HIGH SOUND QUALITY PIEZOELECTRIC SPEAKER |
| 摘要 |
A high sound quality piezoelectric speaker includes a moving coil speaker, a support frame, a vibration plate, and a piezoelectric ceramic plate. The support frame is arranged on the moving coil speaker and the vibration plate is positioned on the support frame. With the piezoelectric ceramic plate being positioned on the vibration plate, the moving coil speaker and the piezoelectric ceramic plate may collaboratively and better handle both high-frequency and low-frequency sounds, exhibiting relatively wide playback band and making sound quality better, to thereby reach the standard of high sound quality and provide users with improved enjoyment of sound perception. |
