Description

Split type magnetism is inhaled concatenation extension's bluetooth speaker Technical Field The utility model relates to a Bluetooth sound box, in particular to a split type magnetic-attraction spliced and expanded Bluetooth sound box. Background The design concept of the split type magnetic-attraction spliced Bluetooth sound box breaks through the limitation of the traditional Bluetooth sound box on sound effect and sound coverage area, and provides a highly flexible and customizable audio solution for users. In order to achieve efficient connection and co-operation between the speaker units, each speaker unit is provided with directly exposed electrical contacts responsible for power transmission and data communication between adjacent speaker units, while the exposed electrical contacts are exposed to the external environment and are susceptible to moisture, dust and other contaminants, thereby causing poor contact or short circuits, and the electrical contacts exposed to the air for a long period of time may undergo oxidation phenomena, resulting in increased resistance, further reduced transmission efficiency, and possibly shortened service life of the whole device.
