(EN) The utility model provides a sounding device. The sounding device provided by the utility model comprises a loudspeaker monomer, and further comprises a shell, a bracket for connecting the loudspeakermonomer with the shell, a first isolation net of which the periphery is connected with the inner wall of the bracket, and a lower clamping plate fixed on the surface, facing the loudspeaker monomer,of the first isolation net, a sound absorption cavity for containing sound absorption materials is defined by the shell, the support, the first isolation net and the lower clamping plate, and the lower clamping plate is provided with heat dissipation protrusions which extend towards the direction of the shell and make contact with the inner wall of the shell. The lower clamping plate and the shellare both metal pieces, the lower clamping plate is directly opposite to the loudspeaker monomer, the shell is communicated with the external environment, and the lower clamping plate is in contact with the inner wall of the shell to form a metal heat dissipation channel, so that heat generated by the loudspeaker monomer is sequentially transferred to the external environment from the lower clamping plate, and the heat dissipation effect of the loudspeaker monomer is effectively improved.
(ZH) 本实用新型提供了发声装置。本实用新型的发声装置包括扬声器单体，该发声装置还包括壳体、连接扬声器单体与壳体的支架、外周与支架的内壁连接的第一隔离网以及固定于第一隔离网朝向扬声器单体的表面的下夹板，壳体、支架、第一隔离网以及下夹板围设形成容纳吸音材料的吸音腔，下夹板上设有向壳体方向延伸并与壳体内壁相接触的散热凸起。下夹板与壳体均为金属件，下夹板直接与扬声器单体相对，壳体与外界环境相通，下夹板与壳体内壁相接触形成金属散热通道，从而实现了扬声器单体产生的热量依次由下夹板到壳体传递至外界环境中，有效提高了扬声器单体的散热效果。
