Description

Technical Field

[0001] The utility model relates to the technical field of ceramic speakers, and particularly relates to a ceramic Bluetooth speaker with a replaceable ceramic shell. Background Art

[0002] With the improvement of the public's living standard and appreciation level, people's requirements for home intelligent devices are also getting higher and higher. For example, for Bluetooth speakers, most of the speakers sold on the market are made of plastic parts, with low value and relatively average aesthetics. Therefore, there are also some ceramic Bluetooth speakers made of ceramic shells on the market, which not only have excellent decorative effects, but also have a high mass density of the shell fired at high temperature, and can form a sound purity and clarity that cannot be compared with traditional speakers. However, when assembling some existing ceramic Bluetooth speakers, the various components of the Bluetooth speaker, such as full-frequency speakers, power supply batteries, circuit main boards, etc., are usually directly installed on the ceramic shell. However, due to the characteristics of the ceramic material, the ceramic shell is prone to cracking and damage when accidentally bumped or dropped. Once the ceramic shell is damaged, then this ceramic Bluetooth speaker will generally be discarded or unable to be used normally, resulting in waste. Summary of the Utility Model
