Improved ceramic bluetooth speaker

Abstract

This utility model relates to the field of ceramic products, specifically to an improved ceramic Bluetooth speaker, including a speaker body, a shell, a sealing cover, a passive diaphragm, a support frame, and sound-absorbing cotton. This utility model uses a passive diaphragm to divide the inner cavity of the ceramic shell into an upper cavity and a lower cavity. The speaker of the speaker body is suspended in the sealed cavity of the upper cavity. The sound-absorbing cotton is embedded in the inner wall of the upper cavity and the top wall of the sealing cover. The air spring effect generated by the audio waves from the speaker body causes continuous changes in air pressure within the sealed cavity of the upper cavity, driving the passive diaphragm to vibrate and enhance low-frequency response. The sound-absorbing cotton absorbs high-frequency reflected noise from the inner wall of the shell and the top wall of the sealing cover to optimize sound clarity, thereby enhancing the low-frequency range of the ceramic Bluetooth speaker to improve its richness and stereo effect, and reducing high-frequency reflected noise to improve sound quality, thus enhancing the user's enjoyment of music.
