How do I embed the Baby Sound Module into a toy?

Use an ABS waterproof casing (15-20g) and sew it inside a plush toy or glue it to the cavity of a hard toy. A speaker outlet must be reserved. The light/touch trigger module requires an exposed sensing area, such as the conductive fiber contacts on a cloth book or the silicone buttons on the palm of a doll.

• It is recommended to embed the AG10/AG13 button battery in the compartment, or use a Micro USB port connects to a rechargeable lithium battery pack.
• Low-power design (quiescent current < 5μA) ensures over 30 hours of continuous playback.

• Connect the module's UART port via a USB-TTL tool and use dedicated software to upload WAV audio files (recommended sampling rate 8kHz).
• Supports multi-track audio effect switching, such as animal sounds and nursery rhyme combinations.

• The light sensor module has an adjustable sensitivity threshold (default 50-100 Lux) to adapt to varying ambient lighting conditions.
• Touch trigger supports single/loop playback mode switching.

• Module edges must be rounded and pass EN71-1 mechanical and physical testing.
• The battery compartment must be equipped with a screw-fastening mechanism to prevent accidental swallowing.

• Operating voltage ≤ 3V, meeting IEC62115 insulation resistance requirements.
• LED flash frequency must be > 100Hz to avoid low-frequency flicker damage.

• The modular design supports SMT mounting and can be mass-soldered onto toy control boards.
• OEM customization services are available, including pre-recorded audio content and housing color matching.

This solution enables rapid integration. Typical applications include soothing toys with sound and music education cloth books.
