Abstract

The invention relates to a novel loudspeaker. An existing loudspeaker needs to be connected with an external power amplifier and an external power supply so as to be driven to make a sound, the number of external accessories of the existing loudspeaker is large, and cost is high. The novel loudspeaker comprises a power supply, a loudspeaker body, a loudspeaker support and a PCB, wherein the loudspeaker support is arranged on the loudspeaker body, and the PCB is arranged on the loudspeaker support. The novel loudspeaker further comprises a voice IC which is welded to the PCB, wherein the PCB is pasted on the loudspeaker support, and a touch prevention non-woven fabric film is arranged on the outer surface of the loudspeaker body. The novel loudspeaker has the advantages that the accessories are integrally arranged, the number of external parts is small, the novel loudspeaker can be used after being connected with an external power supply, the size is small, and use is convenient; compared with an ordinary loudspeaker, cost is saved by 2 times or more for clients on the aspects of use and assembly; a form can be programmed into the novel loudspeaker according to the assigned requirements of clients, and required sounds can be made.

Description

technical field [0001] The present invention relates to a novel loudspeaker. Background technique [0002] Existing speakers need an external power amplifier and power supply to drive the sound, and the external accessories are many and the cost is high.
