Benefits of technology

This patented technology improves upon existing speakers that use magnet systems for sound reproduction due to their compact design. It includes two housings joined at one side called top or bottom shell assembly, where there is also a small loudspeaker unit placed near it's center. When this tiny speaker receives audio signals through its earpiece (earphone), sounds emitted into the air create pressure waves within the device. These pressure waves travel backward towards the listener who wears them over headbands attached to these devices. By placing the micro phone around the ears instead of directly behind each other, the distance between the driver/receiver units becomes shorter, resulting in less interference during signal transmission compared to traditional designs. Overall, this innovation enhances the quality of speech perception while reducing any negative impact they might cause.

Problems solved by technology

This patented technical problem addressed in this patents relates to how to prevent damage from being caused during operation due to accidentally touching or damaging sensitive components within these tiny loudspeakers while also improving efficiency over other types of speakers that have larger spaces than them.

Abstract

The present invention relates to the technical field of electroacoustic products. Disclosed is a miniature speaker. The miniature speaker comprises an upper housing and a lower housing combined together. A vibration system and a magnetic circuit system are accommodated in the space defined by the upper housing and the lower housing. The upper housing is disposed close to the vibration system. The miniature speaker also comprises a hearing-aid voice coil. The hearing-aid voice coil is fixed to the upper housing and is located at the inner side of the upper housing. The miniature speaker of the present invention solves the problem of poor acoustics caused by collision of a lead wire of a vibrating voice coil with a hearing-aid voice coil of a miniature speaker in the prior art, and the miniature speaker of the present invention has good acoustic performance and a better hearing-aid effect.
