Abstract

The invention provides a ceramic loudspeaker which comprises an upper shell, a lower shell, a PCB and a ceramic sheet. The upper shell and the lower shell are in butt joint, and the PCB and the ceramic sheet are bonded and attached to form a vibration assembly. The ceramic loudspeaker further comprises an installation plate located between a bottom plate of the lower shell and the upper shell, and the vibration assembly is bonded and attached to the top face or the bottom face of the installation plate. Due to the fact that the installation plate is located between the bottom plate of the lower shell and the upper shell, a distance exists between the installation plate and the bottom plate of the lower shell; besides, the vibration assembly is bonded and attached to the installation plate, and thus a distance exists between the vibration assembly and the bottom plate; in this way, when the ceramic loudspeaker is applied to a wearable intelligent device, the vibration assembly cannot make direct contact with the outside part such as the human body, and the amplitude of the ceramic loudspeaker is ensured, so that the sound pressure level and the tone quality clearness degree of the ceramic loudspeaker are increased, and the subjective listening effect is improved.

Description

technical field [0001] The invention relates to the technical field of electronic products, and more specifically, relates to a ceramic loudspeaker. Background technique [0002] Wearable smart devices are often equipped with thinner ceramic speakers. The existing ceramic speakers include an upper shell, a lower shell, a PCB board and a ceramic sheet. The PCB board and the ceramic sheet are bonded to form a vibration component; the vibration component is directly bonded Connected to the upper or lower case. During use, when the vibrating surface of the ceramic speaker is in direct contact with the human body, the vibration amplitude of the ceramic speaker is small, which in turn results in a low sound pressure level and poor sound quality clarity, which affects the subjective hearing effect. [0003] To sum up, how to improve the sound pressure level and sound quality clarity of the ceramic loudspeaker, so as to improve the subjective hearing effect, is a technical problem ...
