KT148A Voice Playback Chip: Unlocking a New Intelligent Interaction Experience for Nail Tool Sterilization Boxes

 As consumers' awareness of hygiene continues to grow, the sanitation standards for nail salon services have become increasingly strict.

If tools such as nail clippers, files, and cuticle pushers are not properly sterilized, they can easily lead to cross-infection of bacteria, fungi, or even viruses, causing diseases such as paronychia or onychomycosis.

According to industry research, infection cases caused by improper sterilization of nail tools have been increasing year by year, which not only harms consumers' health but also seriously damages the reputation and operation of nail salons.

Against this backdrop, ultraviolet (UV) sterilization boxes for nail tools have become an essential device in salons thanks to their efficient and convenient sterilization capability.

With the addition of the KT148A voice playback chip, the sterilization process evolves from silent to intelligent and interactive, ushering in a new era of smart sterilization experience.

Voice System Design Requirements for the Sterilization Box

1. For customers:

When they hear, “UV disinfection has started, killing bacteria — please wait patiently,” they directly perceive the salon's emphasis on hygiene, increasing their trust and satisfaction.

2. For nail technicians:

Voice prompts immediately notify them when the sterilization process is complete, eliminating the need to frequently check indicator lights and significantly improving work efficiency.

3.For error handling:

When abnormalities occur (e.g., door not closed properly, UV lamp failure), voice alerts immediately warn and specify the issue, allowing technicians to locate and fix problems quickly, minimizing downtime.
