Custom Preloaded Audio Push Button Sound Bar Module with Multiple Independent Touch Buttons for Lightweight Embedded Sound Box

Comes with multiple separated sensitive touch buttons; every single key can store independent audio files. You can freely customize animal sounds, kids songs, daily sound effects, story voiceovers or musical tones as your book theme needs. Fast sound programming turnaround for mass orders, stable audio output without distortion.

Ultra-thin elongated rectangular housing, specially engineered to be embedded into book spines, side margins or inner pages of board books. Lightweight structure will not bulge or warp the book pages, matching the assembly process of most children book printing factories. Reserved assembly gaps simplify manual and automatic machine installation to cut production labor costs.

The whole sound bar shell is made of non-toxic, odor-free ABS plastic with smooth polished edges, no sharp burrs to avoid scratching kids’ hands. The front surface supports custom full-color waterproof sticker printing—you can print cartoon animals, letters, patterns or theme icons matching your book’s artwork to boost kids’ reading fun.

Adopts low-power integrated voice chip with replaceable button battery design. It maintains clear, loud sound quality after thousands of presses, with long standby life to extend the service life of sound books. Strict 100% sound function inspection before delivery to reduce defective rates for book manufacturers.
