Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar components or components having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
A sound emitting device 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 6, and the sound emitting device 100 may be an audio device.
As shown in fig. 1, 2 and 4, a sound generating apparatus 100 according to an embodiment of the present invention includes: a housing 1, a speaker module 2, a pressure guide 3, a heat sink 4, and a diaphragm 6.
Wherein, the housing 1 may define a mounting chamber 1a therein, and the speaker module 2, the pressure guide member 3, the heat dissipation member 4 and the diaphragm 6 are disposed in the mounting chamber 1 a. The speaker module 2 may include a module housing 21 and a speaker unit 22, the speaker unit 22 is disposed in an installation space 2a defined by the module housing 21, the module housing 21 is provided with a pressure guide member 3 extending toward a direction away from the installation space 2a (upward as shown in fig. 2), the pressure guide member 3 is hollow and is communicated with the installation space 2a, and one end of the pressure guide member 3 away from the installation space 2a is provided with a pressure guide hole 3a.
As shown in fig. 2 and 4, the heat dissipation member 4 may be disposed on the module housing 21, the heat dissipation member 4 may be provided with a heat generating device 5, and a position of the heat dissipation member 4 opposite to the pressure guiding hole 3a is provided with a avoiding hole 4a. When the sound generating device 100 works, the heat generating device 5 generates heat, and the heat generated by the heat generating device 5 can be transferred to the heat dissipation element 4. Alternatively, the heating device 5 may be a chip or a circuit board of the sound generating device 100, and the heat dissipation element 4 may be a heat conductive metal plate manufactured by die casting, aluminum extrusion, stamping, or the like.
As shown in fig. 2, the diaphragm 6 may be disposed at the outlet of the pressure guide member 3 and cover the pressure guide hole 3a, the diaphragm 6 is disposed opposite to the avoidance hole 4a, and the speaker unit 22 may drive the diaphragm 6 to vibrate to drive the air in the installation chamber 1a to flow when in operation. Specifically, when the sound generating device 100 is operated, the diaphragm of the speaker unit 22 vibrates up and down, which may cause the air pressure in the space inside the module case 21 to change, and the air pressure in the installation space 2a changes because the inlet area of the pressure guide member 3 is much smaller than that of the installation chamber 1a, the air pressure in the installation space 2a may intensively act on the diaphragm 6 at the outlet of the pressure guide member 3, and the diaphragm 6 may vibrate up and down along with the operation of the speaker unit 22, thereby driving the air flow in the installation chamber 1 a. Because the heat dissipation part 4 is located in the installation cavity 1a, the heat generated by the heating device 5 is transferred to the heat dissipation part 4, and the air flows and effectively dissipates the heat of the heat dissipation part 4, so that the heat dissipation efficiency of the heat dissipation part 4 can be increased, and the normal operation of the heating device 5 can be ensured.
Alternatively, the pressure guide 3 may be formed as an integral piece with the module housing 21, for example, the pressure guide 3 may be formed as an integral injection molded piece with the module housing 21. Of course, the pressure guide 3 may be formed as a separate piece from the module housing 21, and the pressure guide 3 may be assembled with the module housing 21 by welding or gluing. The structural arrangement of the pressure guide member 3 is not particularly limited in this application.
According to the sound generating device 100 of the embodiment of the invention, the guide pressing piece 3 is arranged on the module shell 21, and the guide pressing piece 3 can guide the air pressure in the module shell 21 to act on the vibrating membrane 6 in a concentrated manner when the speaker module 2 works, so that the vibrating membrane 6 can be driven to vibrate up and down, the air flow speed in the installation cavity 1a can be accelerated, the heat dissipation efficiency of the heat dissipation piece 4 can be improved, and the normal operation of the sound generating device 100 is ensured. Moreover, the sound generating device 100 in the invention has more reasonable and compact structural design and stronger practicability.

In some embodiments of the present invention, the guide surface 21a may extend in the circumferential direction of the guide 3 and be formed in a closed loop shape, whereby the air pressure around the guide 3 may be guided while flowing into the guide 3, and the vibration frequency of the diaphragm 6 may be raised.

As shown in fig. 2-3, in some embodiments of the invention, the cross-sectional area of the follower 3 gradually decreases in the direction of the flow of the air pressure (from bottom to top as shown in fig. 2). Therefore, in the flowing process of the air pressure, the cross section area of the pressure guide piece 3 is gradually reduced, the pressure to which the air pressure is subjected is gradually increased, so that the circulation speed of the air pressure can be increased, the vibration frequency of the vibrating membrane 6 can be increased, and the heat dissipation efficiency of the heat dissipation piece 4 is improved. Of course, the pressure guide 3 is not limited to the above-described structure. For example, as shown in fig. 4, the pressure guide 3 may also be formed in a cylindrical barrel structure.
As shown in fig. 1 and 3, according to some embodiments of the present invention, a plurality of heat dissipation convex hulls 41 may be provided on the heat dissipation element 4, so that the contact area between the heat dissipation element 4 and the air flow may be increased, and thus the heat dissipation efficiency of the heat dissipation element 4 may be increased. Alternatively, the plurality of heat radiation convex hulls 41 may protrude in a direction away from the module case 21. Thereby, the diaphragm 6 can drive the air above the heat sink 4 to flow, so that the heat radiation convex hull 41 can be fully contacted with the air flow. Alternatively, the plurality of heat radiation convex hulls 41 may be formed by press molding.
As shown in fig. 3, according to some embodiments of the present invention, an end of the pressure guide 3 remote from the installation space 2a (an upper end as shown in fig. 2) may be provided with an installation step 31, and an outer circumferential edge of the diaphragm 6 may be provided in the installation step 31, thereby facilitating assembly of the diaphragm 6 with the pressure guide 3.

Alternatively, the outer periphery of the diaphragm 6 may be sandwiched between the pressure guide member 3 and the heat dissipation member 4, whereby the assembly manner of the diaphragm 6 can be made simpler and the operation is facilitated.
