Recordable Sound Module DIYmall USB Horn Button

Description

Product Overview

The DIYmall Recordable Sound Module is a compact, versatile audio playback unit designed for creators who want to add a personal soundtrack to their projects. Housed in a lightweight plastic shell measuring 3.94 x 1.97 x 1.18 inches and weighing just 3 ounces, the module fits easily into greeting cards, small gift boxes, photo frames, and other handcrafted items. It features an integrated horn for clear, audible playback, a push‑button trigger, and solder pads that allow a TTL (transistor‑transistor logic) trigger for more advanced applications. The module includes 8 MB of internal flash memory, accessible via a micro‑USB data cable that makes the device appear as a standard USB drive on any computer. Users can simply drag and drop MP3 or WAV files onto the drive, eliminating the need for special software. The package also contains a battery case that holds three AAA batteries (not included) and a USB cable for programming and charging.

Usage

This sound module is ideal for a wide range of DIY projects. Craft enthusiasts can embed it in handmade music boxes that play a favorite tune when the lid opens. Holiday makers can create personalized Christmas ornaments that greet friends with a recorded message. Parents can design custom photo frames that play a short video clip or song when the frame is lifted. The button trigger offers a straightforward, one‑press activation, while the TTL option lets electronics hobbyists integrate the module into Arduino or Raspberry Pi projects, enabling remote or sensor‑based playback. Because the module is recognized as a USB drive, updating the audio file is as simple as connecting it to a laptop, swapping the file, and disconnecting—perfect for seasonal updates or gifting multiple versions of the same product.

FAQ

What audio formats are supported?

The module accepts standard MP3 and WAV files. Ensure the file size does not exceed the 8 MB internal storage limit.

How do I change the stored audio?

Connect the module to a computer via the supplied micro‑USB cable. It will appear as a removable drive; simply delete the existing file and copy the new one onto the drive, then safely eject.

Can I use the module without batteries?

The module requires power to operate. It can be powered by three AAA batteries placed in the included battery case, or by an external 5 V supply if you solder a suitable voltage regulator to the TTL pads.

Is the horn loud enough for larger spaces?

The built‑in horn is optimized for close‑range playback, such as within a card or small box. For larger spaces, consider adding an external speaker to the TTL trigger circuit.

What is the difference between button and TTL trigger?

The button trigger activates playback with a single press, ideal for simple gifts. The TTL trigger allows the module to be controlled by a low‑voltage signal from a microcontroller, enabling automated or sensor‑based playback scenarios.
