Muro Box-N20 Lite Battery Version is Coming Soon!

Why did we invent this Battery Version?

Designing the Battery Version is a Challenge

When we were developing the first-generation Muro Box-N20 music box, it coincided with the Samsung smartphone’s lithium battery self-ignition incident.

Considering that products with batteries can complicate the process of air shipping and international customers might face difficulties when purchasing music boxes containing batteries, we decided to avoid designing products with batteries from the beginning.

Moreover, products with batteries presented higher design complexities and compliance testing requirements, which posed significant challenges for us as we embarked on product development for the first time in the early days of our company.

Customers expect the music box
containing batteries

However, since we successfully mass-produced and shipped the N20 Music Box in 2020, we have continually received suggestions from customers that the music box should not be limited by the length of power cords or the location of electrical outlets, allowing them to listen to it wherever they desire.

For instance, one customer mentioned their preference for taking the music box to outdoor camping trips, enjoying the natural scenery while listening to the music box’s tunes. He wished for a battery-powered version to make this possible.

We want to thank Jason Huang who shared this photo in our facebook group for Chinese users of Muro Box on 2020/05/01.

Music Box is Your Assist for the Important Moment

Some people also wish to present the music boxes as important gifts on significant occasions (such as wedding proposals or birthdays) and hope that they can play the music smoothly regardless of the presence of electrical outlets on site. If you pull out the music box during a proposal but then have to awkwardly search for a socket, it can be quite embarrassing.

We want to thank our customer, Daniel Wong, who shared his wedding proposal pictures with us. He placed his Muro Box-N20 Standard on a guitar as its resonance box. He sang along with the Muro Box to propose to his girlfriend successfully!

Daniel is also our N40 subscriber, and he plans to buy a Muro Box-N40 during our Kickstarter campaign to present its live performance in his wedding ceremony in 2024!

The Power Bank Still Has a Cord!

We have thought of a wedding proposal scenario before, so we released the Muro Box-N20 Standard model that allows its user to use a USB-C power bank to connect to the music box’s USB-C PD power input. We thought that using a power bank can already increase its portability. Unfortunately, someone still thinks that the Muro Box still cannot get rid of its long power cord to make it less attractive, so he strongly suggests we should hide the power cord.

Hence, making a battery version of N20 has stayed in our to-do list for several years, until now we finally found a good time to make it come true.

Review Our Customers’ True Needs

This year, we are launching a new product, the Muro Box-N40, which comes with higher specifications. Considering the materials and assembly time required for the N40, it is inevitable that this will need to be reflected in the final retail price. While planning crowdfunding for the new model, we realized that this would deviate too far from our original intention – ‘bringing music boxes back into everyone’s homes. So, we paused to think about what most people really need.

Let Everyone Find the Music Box that Fit His/Her Need

Most people probably just want to have a lot of good music to listen to and don’t really care about the self-composition feature. In fact, the Type-C power source is usually fixed on the wall and used as a regular power adapter, except for when it’s used with a portable power bank. Most people don’t care about the difference between it and the traditional DC plug. What everyone does care about is the price and the ability to operate the music box directly on batteries for important occasions.

So, we’ve decided that, during this crowdfunding opportunity, we will launch the battery-powered version N20 Lite model, which has received the highest demand, alongside the N40.

Why do we need to do a crowdfunding campaign for the N20 Lite battery version, while other N20 products are already available in our store?

One of the biggest expenses for mass-produced goods is inventory. Our current resources are insufficient to stock up components without enough new orders, so we need your early support for our Kickstarter crowdfunding in advance.

After a challenging design journey with our previous model, the N20, we were hit by the impact of COVID-19. While we have persevered, unfortunately, we no longer have the extra resources to complete the development of the new product.

Please give us this opportunity to embark on a miraculous journey with all the dreamers of music boxes.

We hope that those of you who have been observing our Muro Boxes for a long time can understand the efforts of our team and resonate with our vision of making music boxes that play everyone’s unique memories. We invite you to support us in the Kickstarter crowdfunding project in October 2023 by pre-ordering our products, which will allow us to collect funds in advance to arrange for production.

Additionally, with the crowdfunding campaign’s record, we can attract more international distributors to support our team to invent more types of music boxes to cater to various users’ needs.

The Overview of the Muro Box N20 Lite Battery Model

If you don’t have the need to connect the music box to a MIDI keyboard or laptop when arranging your own music, the most cost-effective N20 Lite battery version can already fulfill your dream of “using a mechanical music box to play all your cherished memories!”

10k+ Melodies to Choose in Our Muro Box App

Not only can you listen to songs shared by others, but also you can create your own music box melodies using the app. Turning the Muro Box into your music box version of a Spotify player is easy. There are thousands of songs in the music library for you to choose from. Not only that, the N20 version also offers custom music arrangement and engraving services for you to craft a personalized music box!

Add a Rechargeable Battery’s Compartment

The classic N20 Lite version, combined with the long-awaited battery compartment, completely frees you from the annoying wire! The traditional sturdy DC power interface is simply the best choice. With the same features as the N20 series, you can freely play any song you desire.

The battery version requires an enlarged wooden box to accommodate the additional batteries, with the extended side of the casing serving as the battery compartment for using a rechargeable lithium battery pack.

For shipments within Taiwan, the battery will be included with the music box. In other regions, the battery and the music box will be shipped separately and require the user to assemble it on their own.

Larger Wood Box for Better Resonance Effect

The N20 Lite battery version features upgraded sound, delivering a wider and louder resonance that travels further through the spacious casing!

20-Note Scale Can Already Meet Your Listening Needs in Daily Life

The music box mechanism in the N20 Lite battery version is identical to the currently available N20 standard and Lite versions. The wooden box is also crafted from North American hard maple, and the functionality of the rotary knob for offline playlist selection will be consistent with the existing N20 product design.

In the bottom right corner of the photo, you can see that on the front of the N20 Lite battery version music box, there are three grooves that serve as sound holes. The black rotary knob is used to switch between tracks in the music box's offline playlist, moving to the previous or next song, and it is not used for controlling the volume.

Note: Search “official list” in the Muro Box App, and you will find the 30 complimentary tracks we provide.

Resonance Box for Muro Box
(N40 & N20)

We welcome you to place your Muro Box on various surfaces to test how different materials of the table create different sound effects. You can even try to place it on a guitar to see if you love its sustaining sound effect.

In our specially designed resonance box for both N40 and N20 models, the top and bottom wood plates are made with zebra wood. Using zebra wood will make the sounds in the middle and high range sound richer. The sides of the Resonance Box are made with hard maple, which is also commonly used in making guitars, because it will make the sound become brighter.
