Piezoelectric tweeters and automotive tweeters are two different types of speakers that differ in their working principles, usage scenarios, sound generation effects, and applicability.
Firstly, a piezoelectric tweeter is a type of speaker that utilizes the piezoelectric effect to produce sound. Its working principle is to apply an alternating voltage to a piezoelectric crystal, which generates mechanical vibration under the action of an electric field, thus producing sound. The car tweeter is an electromagnetic speaker that works by generating a magnetic field between a metal coil and a permanent magnet through current, causing the diaphragm to continuously vibrate and produce sound.
Secondly, in terms of usage scenarios, piezoelectric tweeters are more suitable for applications that require high-frequency sound, such as ultrasonic testing, sonar, laser interferometers, and other scientific research and industrial applications. This is because piezoelectric tweeters produce sound frequencies of several tens of kilohertz or higher, while automotive tweeters are more suitable for daily applications such as music playback, car navigation, and voice broadcasting.
Furthermore, in terms of sound generation effect, the sound of piezoelectric tweeters is clearer, more delicate, and pure compared to car tweeters, and is less prone to noise and distortion, but its sound is relatively weaker. The sound produced by car tweeters is relatively loud, layered, and has a relatively warm sound quality, but distortion is prone to occur in the high-frequency part.
In terms of application scope, piezoelectric tweeters are more suitable for high-tech, quasi dense instruments and other fields that are not commonly encountered by general consumers, as their cost and manufacturing difficulty are relatively high. Automotive tweeters are widely used in general fields such as automobiles, home audio systems, conference rooms, banquet halls, etc., with relatively low costs and simple manufacturing processes.
In summary, there are differences between piezoelectric tweeters and automotive tweeters in terms of working principles, applicable scenarios, sound generation effects, and scope of application. Therefore, when purchasing and using speakers, it is necessary to choose the appropriate product based on actual needs to achieve better sound effects.
