Abstract

The invention discloses a loudspeaker and an audio device. The loudspeaker comprises a support; a magnetic circuit system which is mounted on the bracket and is provided with a magnetic circuit gap and a conical basin vibration space arranged on the inner side of the magnetic circuit gap; a vibration system which comprises a vibrating diaphragm, an elastic wave and a voice coil, wherein the vibrating diaphragm comprises a conical basin part and an elastic connecting part connected to the periphery of the conical basin part, the outer edge of the elastic connecting part is connected to the support, the bottom of the conical basin part is arranged in the conical basin vibration space, and the elastic wave is connected with the conical basin part and the magnetic circuit system, one end of the voice coil is connected to the elastic connecting part, and the other end of the voice coil extends into the magnetic circuit gap. Thus, the distance between the diaphragm and the upper end of the vibration system can be reduced on the premise of ensuring that the maximum amplitude of the voice coil has a relatively large value, so as to reduce the thickness of the loudspeaker.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to a loudspeaker and an audio device. Background technique [0002] With the development trend of gradually integrating and thinning electronic products (such as TVs) in the current market, higher and higher requirements are placed on the speakers embedded in them; especially for low-frequency speakers, the ultra-thin Sexual demands are getting higher and higher. Due to its bulky size, traditional cone speakers cannot meet the market's demand for ultra-thin speakers. Contents of the invention [0003] The main object of the present invention is to propose a thin loudspeaker. [0004] In order to achieve the above object, the present invention proposes a loudspeaker, comprising: [0005] bracket; [0006] A magnetic circuit system installed on the bracket, the magnetic circuit system has a magnetic circuit gap and a cone vibration space located inside the magnetic circ...
