Abstract

The invention discloses a loudspeaker. The invention relates to an electroacoustic transducer, the invention relates to a loudspeaker, in particular to a loudspeaker for converting an electric signalinto a sound signal in an electroacoustic transducer. The loudspeaker comprises a basin stand with an accommodating space, and a vibration system and a magnetic circuit system which are accommodated in the accommodating space, the magnetic circuit system comprises an annular pole part, the basin stand is made of metal, the basin stand is provided with a protruding limiting part, the annular pole part is provided with an X-axis direction positioning part and a Y-axis direction positioning part, and the protruding limiting part is connected with the X-axis direction positioning part and the Y-axis direction positioning part in a matched mode. According to the loudspeaker, the basin stand is made of metal, the heat dissipation effect of the loudspeaker is effectively improved, the annular pole part is connected with the basin stand in a matched mode through the positioning part, the magnetic cover is connected with the annular pole part through the positioning part, the structure is accurate in positioning, a product is not prone to collision in the vibration process, the acoustic performance of the loudspeaker is improved, and the service life is prolonged; the loudspeaker has the advantages of being good in heat dissipation effect, good in acoustic performance and low in distortion.

Description

technical field [0001] The invention relates to an electroacoustic transducer, and in particular provides a loudspeaker for converting electrical signals into sound signals in the electroacoustic transducer. Background technique [0002] The loudspeaker is an important acoustic component of portable electronic equipment. It is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. The loudspeaker in the related art includes a basin frame with a storage space and a vibration system and a magnetic circuit system accommodated in the storage space. The vibration system includes a diaphragm fixed at one end of the basin frame and is stored in the storage space and The voice coil that drives the diaphragm to vibrate. [0003] However, in the loudspeaker of the related art, the pot frame is a plastic pot frame formed by an injection molding process. This type of pot frame has a poor heat dissipation effect, which is not co...
