Find Your Favorite
Pinewood
Pinewood has a clean white color, which turns slightly yellow after applying transparent protective varnish. Pinewood is easy to process, the material is readily available, the wood grain is clean, and the color variation is stable. Due to its low hardness, the residual echoes are noticeable. However, traditional music boxes emphasize the vibrational sensation of the bass side’s aftertaste, and the more pronounced residual echo is exactly the characteristic sound when used as a traditional music box.
The unfinished Pinewood resonance box is the default version provided with the purchase of the N40 music box, unless you have upgraded to the Pinewood resonance box with clear lacquer finish or the Pinewood resonance box with black walnut lacquer finish, or selected the Millettia Laurentii (Chicken Wing Wood) resonance box for your N40 music box shipment. In those cases, we will ship the N40 with the selected resonance box as per your instructions.
Which Color of the Pinewood Resonance Box Do You Prefer?
Taiwanese Acacia wood
Taiwanese Acacia wood is a deep coffee color, and due to additional heat treatment, it has the highest hardness of all the woods mentioned. The high notes are solid and clear with each note, but they don’t feel as dry or dull as maple. Instead, they have a pleasant, proper aftertaste.
More importantly, it has a unique caramel aroma, allowing you to almost “smell the taste of music” when you’re close to it. Each Acacia wood resonance box is hand-waxed, avoiding spray painting in order to preserve the unique caramel scent created by the heat treatment.
Millettia Laurentii
Millettia Laurentii (its Chinese name means “Chicken wing wood”), as its name suggests, features the most pleasing deep black feather-like wood grain. The sound leans towards cleanliness, but it’s slightly more complex than acacia wood, with additional characteristics reminiscent of the wings of chickens.
The residual echoes in the bass are more pronounced, but it doesn’t feel sticky together like pinewood. Apart from the wood itself lacking any noticeable odor, the sound quality is top-notch. I consider it a reliable choice of wood. However, there is one drawback to the appearance of chicken wing wood: the prominent fibrous texture and occasional small pieces of wood may chip off at the edges.
Please note that this flaw is inherent to the material and unavoidable; we will ship it out as standard quality products.
Summary of Insights from Experimenting with Various Resonance Boxes
Here is the evaluation from Muro Box inventor Dr. Chen-Hsiang Feng, comparing the wood characteristics of various resonance boxes based on sound quality and appearance after actual prototyping:
Considering both sound and appearance, Millettia Laurentii > Pinewood. This ranking also corresponds to the order of hardness of the woods themselves. Music boxes are indeed more suitable for resonance boxes made of hardwood.
N40 Resonance Box Assembly Steps
1. Use your fingers or a screwdriver to remove the 8 hand-twist screws.
2. Screw the 4 shock absorbers into the 4 corners’ holes under the resonance box. Place the 4 shock absorbers above their pads to prevent the shock absorber scratching the table surface.
3. Next, place the sound post. Its primary function is to support the weight of the music box on the top board, while also enhancing sound transmission.
First, adjust the sound post to the appropriate length, then check the length against the edge of the resonance box.
The goal is for the sound post to “just” protrude slightly above the resonance box to touch the top board. As long as there is slight contact, it will be effective. Do not extend it too much, as this could cause the top board to crack. Please be careful to control the protrusion to be less than 1mm.
4. The position of the sound post can be placed according to your preference. Place the top board on the resonance box to feel the contact position of the sound post, or confirm the placement of the sound post from the side lifting holes. Then, screw the hand-twisted screws to fasten the top board on the resonance box. Be sure to tighten the hand-twisted screws to avoid noise during music box playback caused by vibration.
5. We’ve left a little fun for you. In addition to placing the sound post in the middle, you can try placing it in other positions to hear the sound effect. Once you find your favorite position, remember to ensure that the hand-twisted screws on the top board are tightened when experimenting with the sound effect.
6. The C-shaped sound hole on the top board of the resonance box is designed based on the principle of violin sound production. The curved square groove of the Muro Box Logo is for securing the bottom feet of a 20-note Muro Box music box, while the four small circular grooves are for fitting the 4 feet of the N40 music box. The two types of grooves allow customers who own both a N20 model and a N40 model of music boxes to interchangeably use this same resonance box for amplified playback effects.
7. Place the four feet of your N40 music box on the four small circles on the music box, plug in the power, and you will hear the default music box melody (a jingle) when the music box is turned on. You can press the knob on the front side to play the preset music box melody, or start pairing it with your Muro Box App to experience the thousands of melodies in our online music library.
You might be curious as to why only two of the four bottom feet of the N40 music box have these soft pads, instead of all four being installed.
The reason is that we need to ensure that two of the wooden feet make direct contact with the resonance box to achieve the best sound transmission effect. Therefore, only two of the bottom feet are equipped with shock-absorbing pads.

Verified owner很棒的精美禮物 - 我後來改買N40當禮物，非常精美，很有重量感、聲音也很好聽。
The Music Box I’ve Always Dreamed Of - I am a theremin performer and composer.
As the theremin is a monophonic instrument, it often requires accompaniment—typically piano or guitar. However, I’ve always been especially fond of pairing it with music boxes.
Over the years, I’ve explored many types, including disc music boxes and punched-roll models. Yet I continued to long for a high-precision, auto-playing music box that could handle more complex performances.
The Muro Box-N40 turned out to be exactly that. It offers beautiful tone, excellent stability, and precise expression through advanced control. Even real-time performance using a MIDI keyboard is possible, with virtually no latency.
I genuinely believe this is a revolutionary instrument.
In my latest video, I perform Debussy’s Rêverie as a duet with the Muro Box-N40 and theremin. The result was everything I had hoped for.
From now on, I look forward to continuing my musical journey with this remarkable partner.
A Magical Box! - This music box is amazing! I love that I am not limited to a single song. My wife and I have been enjoying listening to a long list of music of varying styles and lengths. The Muro Box N20 is exactly what we were hoping for and we are very happy with our purchase.
分享美妙旋律，傳遞幸福時光 - 收到這只音樂盒時當下的驚奇和幸福,，至今我還未找到適切的描述來表達內心真實的感受。我一向是個很珍重情誼的人，當送禮人將這只音樂盒放在桌上，兩個有著38年情誼的中年女生手忙腳亂地在手機上download app, account login, Bluetooth connect … 當清脆無暇的旋律從音樂盒流瀉出來時，我們相視笑著，宛如18歳的女生啊，很是滿足。這是無疑是當代的科技研發和創作。
過去的音樂盒，我們因為曲目和造型設計而入手、擁有和收藏它，且每個音樂盒隨著時間和人承載了不同的故事。隨著科技的進步，如今，將這只音樂盒插上電源，接下來的聆聽體驗或許是當年一個簡單的發條木盒子或是曾經擁有過旋轉芭蕾舞小女孩的音樂盒的你從未有過的想像吧? 如同當我們拿到第一部行動電話時，可曾想過如今smartphone的存在?
音樂盒外觀簡潔且充滿細節的設計，有著安定厚實的觸感，不論是送禮收禮，甚至入手給自己，在客製化的選項配搭過程更像是享受當代充滿溫度的一杯特調。
我很喜歡它，也傳遞、分享這個美妙的音樂盒給其他人。期待不懂作曲的自己，有一天也能編上一段屬於自己的旋律藉由這只音樂盒奏出。

Hidden musical gem in the middle of authentic Taipei - Came here with my mate on 6/30/2025 — though they’re quite a small company they pack a punch. Unique in that they’re the first company in the world to make an automated instrument that plays music acoustically in your own home, and you don’t need to buy a player piano that’s hundreds of times the price to do it! You can either come here to see the magic live in action or order their music box online to play live music in your home! The people here are really nice and they write a card to everyone who visits as a token of gratitude.
素晴らしい音色 - このオルゴールは、音色が非常に美しく、聴いているだけで心が癒されます。共鳴箱を活用することで音量が増し、離れた場所からでも楽しむことができました。古いスマートフォンを使用した接続では少し手間がかかりましたが、新しいスマートフォンでは簡単に接続できました。総じて、音のクオリティとシンプルな操作性に満足しています。
30年来の夢が叶いました。(A Dream 30 Years in the Making Has Come True.) - 私はオルゴールの音色が大好きで約30年くらい前に初めてオルゴールの曲を作曲し、それから何曲か続けて作りました。
midi音源で自分の曲を再生した時、嬉しさもありましたが当時は現在のリアルな音源やvstもなく「いつか、本物のオルゴールで鳴らしてみたい」という夢を持つようになりました。
それから何年か経ち手回しオルゴールを購入しましたが、当時は白鍵のみで大幅にアレンジが必要な上、長い楽曲には不向きだったり、本物のオルゴールのように自動演奏できないためリラックスして聞くことができませんでした。
2018年にN20のNewsを見ましたが、半音階が使えず購入を断念しました。
理由は、半音階が使えなかったからです。
作曲をする方なら理解できると思いますが作曲を続けていると、どうしても転調や半音階を使ったり、様々なキーで作りたくなります。
N20に半音階がどうしても欲しいと思って、muro boxのプロジェクトを見ていたらN40のプロトタイプの話題があり「出たら必ず買う！」と心に決めていました。
そして、2025年6月…
ついに、私は夢を叶えることができました。
学生だった自分が結婚して家族に、その時作曲した曲を本物のオルゴールで聞かせることができました。
酷鳩の皆さん本当にありがとうございました！
============
I’ve loved the sound of music boxes for as long as I can remember. About 30 years ago, I composed my first piece for a music box, and after that, I wrote several more.
When I played back my compositions using MIDI sound sources, I was happy, but at the time, there were no realistic VST instruments like we have today. I had a dream: “Someday, I want to hear my music played on a real music box.”
Years later, I purchased a hand-cranked music box. However, it only supported white keys and required major rearrangements. It wasn’t suitable for long pieces, and since it couldn’t play automatically like a real music box, I couldn’t listen to it in a relaxed manner.
Then, in 2018, I came across the news about the N20 model. However, I gave up on buying it since it couldn’t play chromatic notes. That was the key reason I passed on it.
Those who compose music can understand this—once you continue writing music, you want to modulate keys, use chromaticism, and compose in various keys.
I really wanted an N20 that could handle chromatic notes. While reading about the Muro Box project, I saw news about a prototype of the N40. I immediately thought, “I’ll definitely buy it when it comes out!” and made up my mind.
And then, in June 2025… At last, my dream came true.
I, who had once been just a student, got married, started a family—and I was finally able to play the pieces I composed back then on a real music box for my loved ones.
Thank you so much to everyone at Cooju!
Verified ownerA Brilliant Device That Brings Music to Life! - Hello,
I'm truly delighted to be using the Muro Box.
I ordered it from South Korea in November, and after nearly six months of use, I wanted to share my experience. I first discovered the Muro Box through its development videos on YouTube, and I was deeply moved by the dedication and passion that went into creating it.
The mechanism is incredibly ingenious—truly admirable from an engineering perspective.
Using the Muro Box app, I played the intro of one of my favorite game OSTs: "To Me, My Childhood" from Lost Ark.
Thank you for creating such an amazing instrument.
Amazing Team!!! - I love my Muro Box N20, it works perfectly on its own, with the included phone app, and I can use midi from my external instruments to control it with no problems. As well I got the resonator box, and I can confirm that it is worth it! The music box sounds louder and the sound really fills the whole room. I would highly recommend these music boxes to everyone.
A beautiful music box - The muro box is one of the best creations of modern times. I found out about Muro Box after searching to create a custom music box, but was a taken aback by the cost of creating a custom movement, and the work required to design something beautiful. When I saw Muro Box, I immediately chose it as the product I wanted. Modernized, sleek, and still respects the traditional beauty of mechanical movements. I am very happy with the product.
無意間完成了她的夢想 - 我是位聲援著名為『凛々咲』虛擬VT的粉絲。會發現MuroBox也是我無意間起的念頭，時間點是在2022/11月底時候，為了慶祝凛々咲的生日企劃而準備禮物。
凛々咲本身也是為創作詞曲的音樂家，當時聽著音樂盒聲音時想到『如果有著一個音樂盒能播放著她的原創曲的話一定很讚』的想法。
於是開始在網路上尋找關於音樂盒訂做的部分，找了許多資料後也間接找到了MuroBox相關訊息
看了以後我很確定我找到我要的答案了，便開始準備禮物事項。
由於生日企畫籌備時間有點趕，一度還擔心會趕不上不過還好感謝團隊的幫忙順利的幫我把禮物給趕工出來也很謝謝劉虹吟老師幫忙編曲凛々咲的原創曲。
最後也把禮物送到凛々咲的手上，在直播中也提到她曾經去過音樂盒博物館去參觀，也夢想有一天希望有她自己音樂的音樂盒，
而我在無意間完成了她的夢想。
