What is a mobile phone speaker
There are many types of mobile phone speakers. Although they work in different ways, they ultimately push the surrounding air by generating mechanical vibrations, causing the air medium to fluctuate to achieve the "electricity-force-sound" conversion.
The mobile phone speaker is divided into three parts: mono, dual and stereo! In mono audio equipment, you can only feel the sound, the front and rear positions of the music, the tone color, and the volume, but not the lateral movement of the sound from left to right. In layman's terms, there are two sound channels. In the circuit, they often transmit different electrical signals. In the process of pursuing stereo sound, electroacoustics only used dual channels at the earliest due to technical limitations. To achieve, so stereo and dual-channel seem to become one thing.
Features of mobile phone speakers
Ultra-thin, light weight, and small space occupation. The energy conversion efficiency is high and the consumption is high. The loudspeaker adopts a full frequency band design, which has the characteristics of wide directivity and low distortion.
