Embodiment Construction

[0023] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0024] Such as figure 1 As shown, the present invention provides a reinforcing part 1 applied to the diaphragm, wherein the shape of the reinforcing part is not limited, and its shape depends on the actual application, such as circular, rectangular, oval and other shapes, according to According to actual needs, it is made into plane, spherical and other shapes, and then compounded on the diaphragm for direct use. The reinforcing part 1 includes a heat dissipation layer 10 and a first support layer 11 and a second support ...

Abstract

The invention discloses a reinforcement part for a speaker diaphragm. The reinforcement part has a multi-layer composite structure; the reinforcement part comprises a cooling layer, a first support layer and a second support layer that are respectively fixed on two sides of the cooling layer; each of the first support layer and the second support layer comprises a through hole penetrating throughtwo sides; the reinforcement part further comprises a filler for transferring heat in each through hole, and the thermal conductivity of the filler is higher than the thermal conductivity of the support layers. Through holes are arranged in the first support layer and the second support layer of the reinforcement part, and the fillers for heat conduction are arranged in the through holes, so thatthermal conductivity of two sides of the reinforcement part is enhanced. The speaker with the reinforcement part can transfer heat from a rear sound cavity to a front sound cavity rapidly, then the heat is dissipated outward through air flowing in and out of the front sound cavity, so that the speaker is cooled rapidly.

Description

technical field [0001] The invention relates to the field of electroacoustic technology. More specifically, it relates to a reinforcement part structure for a diaphragm, and a diaphragm and a loudspeaker to which the reinforcement part structure is applied. Background technique [0002] As a component that can convert electrical energy into sound, the speaker is widely used in terminal electronic devices such as mobile phones, tablet computers, notebook computers, and PDAs. The structure of the loudspeaker generally includes a magnetic circuit system, a vibration system and an auxiliary system, and the vibration system mainly includes a diaphragm and a voice coil. When the speaker is working, the voice coil will generate a lot of heat. Since the voice coil is located in the relatively closed rear acoustic cavity of the speaker, the heat generated by the voice coil is not easy to dissipate to the outside world. [0003] Since the front acoustic cavity of the speaker communi...
