Abstract

The invention belongs to the technical field of electroacoustics, and discloses a loudspeaker. The loudspeaker comprises a magnetic circuit assembly, a vibration assembly and a basin stand; the magnetic circuit assembly comprises a magnetic conductor, magnetic steel and a magnetic conductive sheet, wherein the magnetic conductive bowl is provided with an accommodating cavity, the bottom wall of the accommodating cavity is provided with a bottom groove, the magnetic steel is provided with a first through hole, and the magnetic conductive sheet is provided with a second through hole; the magnetic steel and the magnetic conductive sheet are sequentially stacked on the bottom wall of the containing cavity, the first through hole is communicated with the second through hole and the bottom groove, and gaps are formed between the magnetic steel and the side wall of the containing cavity and between the magnetic conductive sheet and the side wall of the containing cavity. the vibration assembly comprises a voice coil and a vibration membrane, the vibration membrane covers one end of the voice coil, a winding wire is arranged at one end, far away from the vibration membrane, of the voice coil, and one end, provided with the winding wire, of the voice coil is inserted into the gap in an up-and-down moving manner; the basin stand is used for connecting the magnetic conductive bowl and thevibration assembly. The loudspeaker is simple in structure, and the heating temperature of the voice coil can be reduced, so the bearing power of the loudspeaker is increased.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to a loudspeaker. Background technique [0002] The power of the speaker determines the sound quality and loudness of the speaker, but the current carrying capacity of the voice coil directly determines the power of the speaker. At the same time, the heat dissipation performance of the speaker also affects the power design of the speaker. For the speaker in the prior art, most of the coils on the voice coil are made of copper wire, and the heat generated by the copper wire on the voice coil cannot effectively exchange heat with the outside, thus limiting the power of the speaker. Contents of the invention [0003] The object of the present invention is to provide a loudspeaker to solve the problem that the loudspeaker cannot effectively exchange heat with the outside world and the power the loudspeaker can withstand is limited. [0004] For reaching this purpose, the pre...
