AI Technical Summary

Technical Problem

The electroacoustic conversion efficiency of existing speakers is low, which causes most of the signal energy to be consumed as heat, resulting in unsatisfactory sound amplification effects.

Method used

A new sound amplification device is used, including a first diaphragm, a linear flat vibration motor group, a vibration transmission device and a second diaphragm. The linear flat vibration motor group is connected to a power amplifier to drive the first diaphragm to vibrate, and transmits the vibration to the second diaphragm through the vibration transmission device, thereby improving the sound-to-electricity conversion rate.

Benefits of technology

The sound-to-electricity conversion rate is improved, the sound amplification effect is enhanced, and the linear flat vibration motor has the characteristics of low energy consumption, low noise, wide frequency response range and fast response speed, providing better sound quality.

Abstract

Embodiments of the present invention disclose a novel sound amplification device and a novel sound amplification speaker for use in the field of electroacoustics. The novel sound amplification device includes a first diaphragm, a linear flat vibration motor assembly, a vibration transmission device, and a second diaphragm. The linear flat vibration motor assembly is fixed to the first diaphragm; the first end of the vibration transmission device is fixed to the first diaphragm, and the second end is fixed to the second diaphragm. The vibration transmission device is a rigid body. The linear flat vibration motor assembly is connected to the output end of a power amplifier for amplifying sound signals, and generates vibrations driven by the sound signal output from the output end. The novel sound amplification speaker including this novel sound amplification device can improve the electroacoustic conversion rate and provide high-quality sound amplification.
