  • Publication number: 20220408167
    Abstract: The present disclosure provides a loudspeaker module and an electronic device. The loudspeaker module comprises a module housing and a loudspeaker unit, wherein the module housing has a cavity and the loudspeaker unit is accommodated in the cavity, the loudspeaker unit divides the cavity into a front acoustic cavity and a rear acoustic cavity; wherein a sound outlet hole is provided on the module housing, the front acoustic cavity is communicated with the sound outlet hole by a sound outlet channel; wherein a concave-convex structure is provided separately in a region of the module housing corresponding to the sound outlet channel. According to the present disclosure, resonance of the module housing can be effectively suppressed, to achieve the effects of increasing high-frequency sensitivity of the loudspeaker module and reducing distortion.

  • Publication number: 20180270580
    Abstract: A voice coil and a miniature loudspeaker provided with the voice coil, which relate to the technical field of electro-acoustic products. The voice coil is formed by winding a wire. The number of wound layers of the wire is an even number. There is a height difference between a starting outgoing line position of the wire located at the innermost layer and a tail outgoing line position of the wire located at the outermost layer; and the height difference is less than 1.5 times the diameter of the wire. The voice coil and the miniature loudspeaker provided with the voice coil of the present invention solve the technical problem in the prior art that a voice coil breaks easily when working under large displacement. A voice coil lead of the voice coil and the miniature loudspeaker provided with the voice coil of the present invention is not easily broken and highly reliable, has a long service life, and can be suitable for a developmental tendency of miniature loudspeaker products.
