Muro Box−N40 音箱與共鳴箱意見調查結果
大家好，我是Muro Box 發明人-馮振祥，以下為本次進度報告的重點：
1. 解釋目前設計的方向
2. 摘要目前問卷 #5結果Part1:音箱設計，標示既有客戶和尚未購買的客戶的回應比例，呈現N40新產品訂閱者的整體意見趨勢
3. 感謝幾位讀者特別花時間查詢資料，以提供我們後續進行音質/工法/材質相關研究
[1] 解釋目前設計的方向
真的非常感謝各位的建議與踴躍的回應。經由問卷，在統計上我了解了大家的喜好與人數比例，但更重要的是，經由多位顧客提醒，我終於體會到音樂盒真正的核心價值為何。
簡單說，我所得到最重要收穫，就是追求更好的聲音是必須的，但不代表是要將音樂盒直接放到某種樂器的框框裡。
比如說，前兩天一位彈奏琵琶的顧客A到我們三重辦公室取貨音樂盒，我們就在現場訪問他對各種音箱的想法，包含現場直接拿出吉他當作音箱做為測試。沒想到A一聽就直接說吉他殘響較大，歌曲節奏較快就不適合。
其實我一聽A的說明就直接震驚了。因為大型音樂盒的殘響還遠遠長過我們目前的N20小音樂盒，所以聲音延續更長 – 我一直理解是一個”好”的音樂盒特質。
聲音的好壞真的是很主觀的。我們如果以吉他為設計一定會顧此失彼，學誰都是不對，像音樂盒該有的樣子才是正確答案。也就是外觀是方形的盒形發出的聲音，是目前最符合音樂盒價值觀的選擇。
另外一個大問題是音箱的大小。毫無疑問箱體越大越符合音樂盒華麗的聲音效果。但如果按照聲音的波長來計算，一公尺寬的箱體才是我們最佳的尺寸，這並不符合我們目前顧客對產品大小的期待。
所以目前最佳的作法，應該是在達到基本共鳴效果的同時，盡量縮小尺寸，讓想要有擴音效果的顧客自行將N40與喜歡的外部共鳴箱結合。
也就是我們會將N40箱體 (350 x 200 x 90 mm) 限制大小，約為我們目前N20共鳴箱N20-RB的大小。也就是會提供基本的腔體容積給予N40低音基本的支援，讓N40就算單獨播放也不至於聲音太過單薄。但如果想要追求更豐富的聲音，請各位自行將N40與身邊的樂器結合。
因此我們預計會特別設計額外的吉他外型共鳴箱，但會比較晚才執行。目前我們會專注在完善N40本身的設計。
針對外置共鳴箱，我們音箱會設計額外導音柱(soundpost)，以加強將聲音傳遞給外置共鳴箱時的效果。
至於外型，既然沒有要模仿樂器，我們將會延續系列中機心外露的透明上蓋，木盒”方中帶圓，圓中帶方”的意象。材質我們正在思考中，除了木頭之外，碳纖維也是我們目前考慮的選項之一。
[2] 摘要目前問卷 #5結果，呈現N40新產品訂閱者的意見趨勢
本次問卷 #5 總共收集到91位讀者回應，其中67位是英文讀者，24位是中文讀者。
67位英文讀者中，已買過N20智慧音樂盒的有32位 (約47.3%)，尚未買過者有35位(約52.3%)。24位中文讀者中，已買過N20智慧音樂盒的有14位(約58.4%)，尚未買過者有10位(約41.6%)。
a.是否同意我們延後開發N40經典款?
67位英文讀者中，同意延後者有57位 (約85%)，不同意者有35位(約13.1%)，其他意見1人。
24位中文讀者中，同意延後者有20位 (約83.3%)，不同意者有4位(約16.7%)，其他意見0人。
不同意者主要是希望N40經典款與N40標準版可以同時開發推出，以滿足不同客群需求。
補充說明N40標準款與N40經典款差異：
◆Muro Box−N40 標準版 (Muro Box−N40 Standard):
基本上延續N20 標準版的零件與外觀設計，盡量重複利用現有零件，售價2至2.5倍N20價格。主要增加功能是傳統DIN 5 的MIDI 接口，與6.5mm Audio Out。 主要客群是本來已有在玩MIDI鍵盤等相容數位樂器的專業音樂玩家。
◆Muro Box−N40 經典版 (Muro Box−N40 Classic):
更換所有可以讓品質更好的零組件(如基座，齒輪，4片音梳)，外觀將回歸到傳統的方正音樂盒外型。由於產量少無法規模化生產，售價至少會是4倍以上。主要客群是將N40經典款智慧音樂盒當傳家寶收藏者，偏好外觀有獨特工藝設計者。

[3] 其他客戶針對音箱設計的補充建議
感謝以下中文讀者留言補充說明建議給我們：
1.薛小姐(N20客戶)：我會買是因為我喜歡音樂盒，我喜歡音樂盒發出的聲音。就算他受限至於龐大的音箱，發不出完美的聲音我也喜歡。市面上的播放器那麼多種類，要達到完美 並不一定要在這個上面去達成。
2.劉先生(N20客戶)：有實機辦試聽會聽再看看，或許可等比例再縮小。也可以用N20試看不同比例音箱。
3.田先生(N20客戶)：要做到40音階，其實就是朝鋼琴的概念在做，所以聲音的品質必然是重要的（包含機械噪音的降低），承接B20的操作功能，如果N40沒有在聲音上接近樂器的感覺，我到覺得就沒有開發的必要，因為到N40的價格一定是更高的，會願意擁有的客群一定對聲音的質感與外觀會有要求，對我而言應該會與我的高級音響放在一起成為聆聽音樂的另一種來源。他可能會成為少數人的禮品，但大多的應該會是對樂器本身的喜好而購買！
4.曾先生(N20客戶)：外觀第一，音色次之。總之外觀可以不傳統，但不可以大，更不可以醜。
5.卓先生(N20客戶)：能在音箱外觀上取得一個比較不突兀的外形。
6.花先生(N20客戶): 關於音箱的設置，我的建議是(在下非傳統音樂盒粉)，音樂盒放在不同的介質本來就會有不同的共鳴音色，這也是它的特性。 希望N40可以維持 N20的規劃 有基本能傳遞共鳴小巧又精美的機身、復古又時尚的造型(要求還真多) 一樣有選配的音箱(要強迫包套推銷 也OK啦)，若是分離式音箱 可以規劃，N20 N40都可以放置的溝槽。……我小時候頑皮把音樂盒機芯拆解，到處擺放，可以有很多不同的音色，印象最特別的是放在蛋捲鐵盒，音色會變成電音。…….關於貴司實測 吉他音箱的影片，吉他的琴弦已裝設，只要音箱共鳴，琴弦也會共振。 不知是否是這原因 ，才會有文中提到的貼近吉他音色，音箱是有它的響應特性，但是琴弦 機芯才是音色的本體，同把吉他，安裝鋼弦或尼龍弦也會有截然不同的音色。
7.陳先生(N20客戶)：我覺得音箱的存在是為了達成音樂盒演奏上的需求，例如增加高音域的飽滿度、利用擴增尾韻去遮掉機械作動音、提升快速音群的辨識度等等，而不是為了「像某個樂器一樣好」，因此應該會產生擁有自己形狀的共鳴箱才對，而不是直接像某個樂器。
8.王先生(N20客戶)：可以具有樂器的功能，但是外觀更有特色較佳。
9.張先生(非N20客戶)：敝人有許多不同的樂器，有琵琶、Alto烏克麗麗、玩具鋼琴、木箱鼓、秦琴（類似三弦琴）等等，我非常支持只做音樂盒本體，聲音造型則是自己找共鳴箱。音樂盒本體小的話，才能利用不同的樂器共鳴箱箱體來發出聲音，這可以「玩」出不同有趣的聲響，甚至是多買幾台放在不同的樂器共鳴箱上協同演奏的可能性。另外，貴公司也可以推出針對N40音樂盒設計的專用造型共鳴箱的周邊配件，可以搭配N40來使用，例如說是迷你平台鋼琴造型、留聲機造型，甚至是嶄新造型等等，這也建議找聲響工程師的顧問跟木工業者來進行造型開發，屆時N40 可以像是一個核心模組植入這個共鳴體的一個「洞」，完成「指揮艇組合」，就可變成一個嶄新的樂器，這對於沒有樂器的一般人，會很有吸引力，於是可以同時可以滿足演奏、創作的音樂人還有一般愛樂者的需要，另外這種音樂盒跟不同造型共鳴箱合体變成一個新樂器，也可能可以申請專利，或著制定出「標準尺寸規格」（可能不只置入，可能還包含插銷孔位，方便結合），讓第三方有意願來生產各式各樣有趣的共鳴箱箱體。
10.瓦希里亞(非N20客戶)：看過國內外的大小型音樂盒，大部分都是利用類似鋼琴的音箱或者號角喇叭的方式。你們要不要參考看看台南的文鼎留聲博物館的館藏，如果體積變這麼大，乾脆弄個可以放音樂紙捲機構進去。
11.Tony(非N20客戶)：入門的產品多賣一點，是好的決定。 這可以是長遠的方案。
感謝以下英文讀者留言補充說明建議給我們：
1.Jush K. (N20 customer): Consider forming a partnership with my colleagues at Vienna International. We distribute Hailun, Petrof, and Fazioli pianos through the US and global markets. Hailun, specifically, has perfected the meniscus (membrane) spruce soundboard for their grand pianos. A material such as this will be crucial to eliminate warranty claims on cracked soundboards in your N40 music boxes. This material could produce a tone similar to an N40 placed on a finely made acoustic guitar in a far more compact package at a lower cost. Email me and I will happily discuss ideas at length at no cost and later will introduce you to my colleagues. Your company deserves to succeed!
2.Bill Y. (N20 customer): Is it possible to have resonance boxes being modeled upon other instruments? For example, the resonance box of an Erhu is significantly smaller than a guitar (or even a Ukulele). Its less cursive shape may also allow better placement of the PCBs and other components. The existence of 中胡/二胡/高胡 shows that the size of the sound box could be matched to the range of the instrument.
3.M.Zahid (N20 customer): Keep the body like a traditional wooden box. The sound of a music box doesn’t really need to be that big. Additional sound boxes can always be made for resonance. Focus on the movement and comb and the original sound. Thank you.
4.M.J. Kim(N20 customer): Hello, I’m a very good user of Murobox n20. When I asked my friends about the charm of the n20, they said that the movement of the cogs while playing makes me feel comfortable! So I want to be able to see the cogs spinning when Murobox is playing 🙂 And I think the design of n20 is perfect. I think both men and women will like the round design. I’m looking forward to the release of the n40! Of course, the n20 is great, but some of the music was limited to play. Lastly, thank you for making a good product that I’ve dreamed of since I was young.
5.John S. (N20 customer): Make it beautiful so ladies will display it.
6.Makoto B. (N20 customer):
(1) I think the sound quality is important for the people who want to use N40 as a musical instrument, but the suitable size for my small living room is also important for me. I prefer N20 type one and the separate resonance box option.
(2) Sankyo provided the mechanical movement of a 20-note hand crank music box and some maniac makers installed it on a guitar-like sound box. One example is named “Garyu”.
(3) Another point is the play speed. The hand crank music box can change the speed manually and if Muro box has such function, it may widen the expression.
7.Laurent B. (N20 customer): vous avez toujours eu de très bonne idée je vous fais confiance des choix que vous allez faire (English translation: You have always had very good ideas, I trust you with the choices you are going to make.)
8.Brandon P. (N20 customer): I am very much looking forward to the N40 and can’t wait until I am able to purchase one. Thank you so much for the effort to create it!
9.Christophe D (N20 customer): I think that the shape has to be studied and adapted to the sound you want to get (a guitar body is for the sound and spectrum of a guitar… a musicBox probably deserve a specific shape and internal volume, and wood selection, and braces, etc.).To me the design of the music box itself MUST include the connection to the soundboard/sound box : like the bridge on a guitar, this is a key part of the sound transmission). Since the Muro Box needs power, it may be interesting to have a piezo on it and drive the soundbox using a transducer (and small amplifier) instead of a traditional mechanical coupling via a bridge. That would also give a lot of freedom to the design.
10.Kilsang L. (N20 customer): Hello. I prefer boxed designs. I think the music box’s charm is its incomplete sound quality and tuning. I think the sound quality of Murobox is already similar to Kalimba, so it’s beautiful enough.
11.Jordan T. (N20 customer): I think the recording of the guitar sounded LOVELY. You still retain the mechanical noises and the music box imperfections. To me, it’s about easy amplification and I’d much prefer that vs the practicality of a smaller size. I just think it’s very important to have the acoustic sound resonate in a stronger way (like it is with the guitar); unless you built in a small contact mic that helped. To me, that was the one thing missing from the N20 which I wished it had…and when I tried to mic it, it became too noisy and cumbersome.
12.Bert F. (N20 customer): We discussed my views of making different types of Muro Boxes for different audiences (one as a beautiful toy or gift and one for musicians). The toy variant (and I don’t mean that in any negative way!) should be nice-sounding and beautiful, the musicians’ version should be rugged, have MIDI, a wide note-range with all notes, and should offer an inbuilt pickup system. It should have an inbuilt pickup system and an output jack for connection to a mixing desk or amplifier.
13.Omeylan T. (N20 customer): Dear Muro Box Members, There were a lot of questions, how exactly should the N40 sound. In my opinion, it should be as close to the polyphonic play watches of the forelast century as possible. These are the iconic souls one finds so attractive in the old big watches. A very nice example is here: https://youtu.be/e6bRThvBnC4 By the way, this is also showing that an amazing sound does not necessarily require a shape that mimics other musical instruments (so no need to put the new box in a guitar body). After all, we do not want to get a bit differently sounding guitar, we would all like to hear an authentic sounding music box. Warm greetings from Germany, Sincerely, Omelyan.
14.Jae H. C. (N20 customer): My biggest complaint with N20 was having only the diatonic scale notes available. I didn’t notice this issue at the time of purchase and wouldn’t have bought it if I had known, as it significantly limits the playable repertoire. I am glad to see the range of notes available on N40. I am all for having as many chromatic notes available as possible for a wider range of possible repertoire, including new compositions. I believe a music box should be what it is, mechanized or not, to serve that function. Having a resonance box to make it pretend to be a live musical instrument for its sound’s sake is oxymoronic, in my opinion. One could always place the music box on a resonant surface to make the sound louder or rounder. I placed my N20 on a wooden shelf to find it too loud for my taste. To me, music boxes are attractive in their delicate nature, both in their complex construction and the precious sound produced. I don’t understand why some people would like to record the music box’s sound, it mutes the whole concept of music boxes. My hats off to the inventor, it’s truly an innovative product, and I look forward to seeing N40. All those available notes would be wonderful! I am a professional pianist and am itching to code in my favorite pieces and my own compositions, which I can finally do with N40. Good luck to you all!
15.Jeremy Y. (N20 customer): I think N40 is fascinating because it has 40 notes (meaning a wide sound range), but timing accuracy is more important than number of notes. Actually my MuroBox (the first model) has not good accuracy of playing notes, and I have been told that I must wait for a new model or update. so I request you to dedicate yourself to improving timing accuracy. Thank you.
16.Joeri (N20 customer): Dear Muro Box Team, Go for quality. That takes time. Use the time so good as possible. Thank you for your great products.
17.Nathan R. (not N20 customer): I’ve emailed separately, but I’m looking forward to this N40 product!
18.Dror F. (not N20 customer): I would like a total chromatic box.
19.Siegfried (not N20 customer): (1) Go for the kalimba look. (2) Look at the sizes of disc music boxes with approximately 40 teeth, but I would prefer rectangular not square.
(We want to especially thank Siegfried for sending us a lot of his research on music boxes. For the theme of this update, “the sound box design”, we only presented a tiny part of his suggestions.)
20.Steve (not N20 customer): I believe people will want to put this on their shelf to display, so if you make it too large with a big sound box some people may not buy it. You can always sell a sound box add-on for the N40 for people who want one. Not only will keeping the N40 smaller keep costs down, but it will reduce shipping as well. The lower you can get the N40’s price the better. If it costs too much I believe you will have a harder time selling it. Keep up the great work!
21.Simon B. (not N20 customer): I would like the sound to be like the antique Swiss boxes with a deep rich sound.
22.Ken B. (not N20 customer): First of all THANK YOU for sharing your design considerations and research and including us in the process each step of the way. Based on what you’ve told me, my ideal design would be a square soundbox. It would sound good yet retain both the look and the typical sound of a music box. I was one of the people who spoke of treating it as a musical instrument, but my intent was always for it to look and sound like a high quality music box, not to move away from that sound to some other instrument tonally. That said, I think the experimentation you did was a worthy pursuit. Again, thank you. I’m more excited than ever for the N40! Also, looking at the pitch chart and the different compromises between range vs. chromaticism, I can envision an N50 or N60 in the future 🙂
23.Ian S. (not N20 customer): Sometimes I get so focused on solving a difficult problem that I need to take a step back, take a deep breath, and recenter myself. I think this is what’s happening here. A music box should be small, portable, and easily giveable as a gift. The scale should be continuous, this is not an instrument, it is a music box. I know people have done some neat things with the murobox but it is a music box, it has limitations. People who want a music box want those limitations. They are supposed to make a small amount of noise not resonate like an instrument. I understand there are people interested in this who say they want this, but I’d be very surprised if they actually buy one of the guitar shaped monstrosities. I can use my iPad to write songs that sound like music boxes with no limitations. A midi keyboard. This is not what a music box should be like. Without limitations there can’t be the creativity that makes this project exciting, so please don’t try to turn it into an instrument. If people want to do that, they can modify it themselves. Keep a music box style design. Make it look like the n20 or set it into a different type of box maybe, but remember why you started this project in the first place.
24.Aya S. (not N20 customer): To be clear, I want the N40 Music Box to have the same design as the N20, with the relatively small rectangular resonance box. Trying to manufacture and add a massively large guitar-shaped resonance box will not only take up too much space in the home, it will also drive up the unit cost (not to mention the shipping cost) of the N40 to such a high extreme that the final product will be completely beyond the ability of most people to pay! (I certainly would not be able to purchase it in that form.) Please keep this in mind. Most of us are not millionaires. And yes, I think it is the greatest idea to make the N40’s scale start at F3 to be more similar to the paper strips of the regular 30-note music boxes, for the sake of sharing online. Thank you for listening to our opinions.
25.Alex B. (not N20 customer): I wanted this Muro N40 Standard to be MIDI controllable in the studio environment and to place upon various resonance boxes of my own to get different sound characters while accompanying my performances on other acoustic instruments and recording that with microphones in the room. I don’t really want to hear any machine aspect to it (motors turning and grinding). I don’t want any gaps in the scale. I don’t think it would look very pretty or cute mounted to an acoustic guitar body, but maybe borrowing from another instrument besides guitar. It should be able to amplify on its own just enough to reasonably compete with the motor noise and win that battle. Then we can set it atop our own larger resonance boxes such as acoustic guitar or Onde. Anyway, I am a bit confused about the difference between standard and classic, yet I believe you mean classic is the more basic one, without midi control. Can the N40 have an 18650 (or other) battery compartment and be rechargeable for standalone use (possibly via USB-C? Is the MIDI connection via USB-C? I wish it was a MIDI host and/or had MIDI DIN so I can play it most conveniently. Also, if it would receive MIDI over Bluetooth – that would be truly fantastic!
26.Nicolas (not N20 customer): You always talked about the shape, but did you consider taking another material, for example another kind of wood or perhaps something completely different like carbon fiber? There might be a significant impact too. By the way, I am not sure what you meant by talking about sound improvement. I have the feeling you speak about a louder and vibrant sound, but I don’t think this is the requirement for a music box. I think the music box should sound harmonious and soothing, it does not have to be loud and vibrant. Just my opinion, of course.
27.Daniel (not N20 customer): Offering different sound boxes seems like the way to go: create/sell two or three different sound box options so that customers can choose what best meets their individual tastes/needs.
28.Adam (not N20 customer):
(1) I truly think the best design would be the one that sounds the most like a music box. When I want to hear a music box or use one in recordings, it’s because I want to hear the character and feel the nostalgia of a music box. While changing the body shape to emulate something like a guitar body may make the N40 sound more “hi-fi” and give it a more extended frequency response, I personally believe you lose the character of what makes a music box so charming. Thank you for the opportunity to comment on the design!
(2) I would prefer the N40 not need a large additional resonance box. Ideally, the natural volume of the N40 design would be loud enough to clearly record in a quiet room. I would be in favor of making a resonance box optional, as you can buy separately for the N20 currently. But I would not want it to be essential to the N40’s performance.
29.NaNo (not N20 customer): 1. I hope the size of the product is not too big. 2. Design can give up to some extent for sound. 3. I hope the machine noise is low.
30.Austin (not N20 customer): People probably disagree about perfect sound / imperfect sound. Maybe you can make multiple resonance boxes someday? (Modular, sold separately from the device) I would also be curious about a “soundproof” box (not now, but eventually). But any option shown is fine. I trust your decisions, follow your heart.
31.Evan (not N20 customer): If the N40 Classic is not available with the 2023 funding, I will wait for the N40 Classic, whether that’s 2024, 2025, or further away.
32.Alexis (not N20 customer):It would be a deal breaker to have a rechargeable battery instead of requiring the music box to be plugged in all the time. Would definitely increase portability and usability.
