Loudspeaker capable of reducing distortion

Abstract

The invention discloses a loudspeaker capable of reducing distortion, which comprises a shell, and a vibration system and a magnetic circuit system arranged in the shell, and is characterized in thatthe vibration system comprises a diaphragm fixedly connected with the shell and a voice coil assembly for driving the diaphragm to vibrate, and the voice coil assembly comprises a skeleton suspended at the bottom of the diaphragm and a voice coil part arranged on the skeleton; an FPC board is fixedly arranged below the framework; the FPC board comprises an outer ring, an inner ring arranged in theouter ring and an extension part connected to the outer edge of the outer ring, the outer ring and the inner ring are connected through a cantilever, the inner ring is fixedly connected with the lower end of the framework, and the extension part penetrates out of the shell; a conductive layer communicated with an external circuit is arranged in the FPC board, and the conductive layer is electrically connected with the voice coil lead of the voice coil part. According to the invention, the FPC board is fixedly connected to the lower end of the skeleton, so that the amplitude of transverse vibration of the voice coil assembly during vibration can be greatly reduced, the stability of longitudinal movement of the voice coil assembly is improved, and the effect of reducing distortion is achieved.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker for reducing distortion. Background technique [0002] Existing micro-speakers generally include a diaphragm, a voice coil assembly, a washer, a magnet, a yoke, and a housing, and the magnetic circuit of the speaker includes a washer, a magnet, and a yoke. In the current loudspeaker, the electrical connection terminals connected to the external circuit are generally provided on the housing. When the speaker is assembled, the voice coil lead wire of the voice coil assembly needs to be passed from the inside of the housing to the outside of the housing to be welded to the electrical connection terminal. The operation process is complicated and difficult, and it is inconvenient to weld. Not only the welding quality is poor, but also prone to defects such as false welding, and it is also easy to cause disconnection of the voice coil lead, which affects the yield ra...

In the current loudspeaker, the electrical connection terminals connected to the external circuit are generally provided on the housing. When the speaker is assembled, the voice coil lead wire of the voice coil assembly needs to be passed from the inside of the housing to the outside of the housing to be welded to the electrical connection terminal. The operation process is complicated and difficult, and it is inconvenient to weld. Not only the welding quality is poor, but it is prone to defects such as false welding, and it is also easy to cause disconnection of the voice coil lead, which affects the yield rate of the speaker.
