Abstract

The invention relates to a loudspeaker, comprising a sounding module, a power amplifying circuit board and a fixed outer frame which contains the sounding module and the power amplifying circuit and fixes the sounding module and the power amplifying circuit board in the frame; the sounding module comprises a thermal sounding element, and at least one first electrode and at least one second electrode which are electrically connected with the thermal sounding element; the power amplifying circuit board is electrically connected with the thermal sounding element by the first electrode and the second electrode. In the invention, the thermal sounding element and the power amplifying circuit board are assembled to a packaging structure together to form an integral product structure, so as to be convenient for application and dissemination and realize marketization.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a loudspeaker based on carbon nanotubes. Background technique [0002] A loudspeaker in the prior art generally includes a box body and an electro-acoustic element disposed in the box body. The electroacoustic element includes a diaphragm and a magnetic structure. The electroacoustic element drives the vibrating membrane to vibrate to produce sound through the input audio electric signal under the action of magnetoelectric induction. In addition, in the prior art, the input audio signal is usually amplified by a power amplifier circuit before being input to the electroacoustic element. The power amplifier circuit and the above-mentioned electro-acoustic element can be integrated in the box to form the loudspeaker. When the loudspeaker is in use, the power amplifier circuit is connected with an external audio signal source through a data line. However, the electro-acoustic element emits sound ...
