Audio Speaker System Using Piezo Diaphragm - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240215451 titled 'Audio Speaker System Using Piezo Diaphragm
Simplified Explanation:
The patent application describes an audio speaker system that includes an amplifier and a piezo diaphragm. The amplifier is connected to a first reference voltage node and the piezo diaphragm consists of a metal plate with two piezo films - one functioning as a speaker and the other as a microphone.
- The audio speaker system includes an amplifier connected to a first reference voltage node.
- The piezo diaphragm consists of a metal plate with two piezo films - one for speaker function and the other for microphone function.
- The output terminal of the amplifier is connected to the first piezo film, while the negative input terminal is connected to the second piezo film.
Key Features and Innovation:
- Innovative use of a piezo diaphragm with dual functionality as both a speaker and a microphone.
- Efficient design with the amplifier connected to the first reference voltage node for optimal performance.
- Utilization of piezo films for improved audio quality and functionality in the speaker system.
Potential Applications:
- Consumer electronics such as smartphones, tablets, and laptops.
- Automotive audio systems.
