Definitions
- the low-frequency sound effect of the speaker module needs to be improved, and the bass effect of the speaker module is mainly controlled by the volume of the rear sound cavity.
- the bass effect is better.
- electronic products are becoming thinner and smaller, and the size of the speaker module is also limited. Therefore, it is impossible to expand the low frequency of the product by increasing the volume of the rear cavity.
- the technical problem to be solved by the present invention is to provide a speaker module, which can effectively dissipate heat from the speaker module, effectively expand the low frequency of the product, and have a certain position and size of the sound hole of the speaker module.
- the internal space of the speaker module can be saved to increase the size of the speaker unit.
- the peripheral frame further includes a middle case coupled between the upper case and the lower case;
- the middle case includes an outer side wall combined with the upper case and the lower case, and is disposed inside the middle case
- the sealing rib position is a welding rib, and the sealing rib position is welded and fixed to the inner side wall of the middle casing.
- the speaker unit, the partition wall of the middle case, the outer side wall of the middle case, and the lower case together form the rear acoustic cavity;
- the open end is an opening in which the inverted pipe communicates with the rear acoustic cavity, and sound waves in the rear acoustic cavity enter the inverted pipe through the open end.
- the middle case includes a fixing portion that houses the speaker unit; the speaker unit and the upper case and the middle case together form a front sound cavity of the speaker module.
- the speaker module of the present invention is provided with an inverted phase tube connecting the rear sound cavity, which can significantly enhance the low frequency sound effect of the product and improve the bass effect of the speaker module;
- the speaker module can realize the heat dissipation and air pressure balance of the rear sound chamber through the inverted tube; in addition, since the inverter tube and the speaker unit share the front sound chamber and the sound hole, the space inside the speaker module can be saved. It is beneficial to increase the size of the speaker unit, which is beneficial to improve the acoustic performance of the product.
- FIG. 2 is a perspective view showing a three-dimensional structure of a speaker module of the present invention combined with a middle case;
- FIG. 3 is a schematic perspective view showing a three-dimensional combination structure of the speaker module of the present invention
- the peripheral frame of the present embodiment further includes a middle case 12 coupled between the upper case 11 and the lower case 13; the front acoustic cavity of the embodiment is formed by the upper case 11, the middle case 12 and the speaker unit 2, and the rear sound chamber It is formed by the lower case 13, the middle case 12, and the speaker unit 2.
- the specific structure diagram of the speaker unit 2 is not shown, and includes a vibration system and a magnetic circuit system.
- the vibration system includes a diaphragm and a voice coil coupled to one side of the diaphragm.
- the magnetic circuit system includes a washer, a magnet and a basin frame which are sequentially combined.
- the magnetic circuit system forms a magnetic gap for accommodating the voice coil.
- the sealing joint between the upper casing 11 and the inner side wall 122 is not limited to this manner, and the sealing rib 110 may also be a welding rib.
- the welding ribs on the upper casing 11 and the inner side wall 122 are fixed by ultrasonic welding. Combine.
- the edge of the upper casing 11 and the outer side wall 123 of the middle casing 12 may be sealed and fixed by means of gluing or ultrasonic welding, and this embodiment is a rubberized sealing.
- the sound hole 10 of the speaker module of this embodiment is located on the side, as shown in FIG. 3, but is not limited thereto. This position may also be disposed on the side facing the speaker unit 2, and the speaker unit 2 is fixedly coupled to the middle case. Inside the fixing portion 121 of 12. The inner side wall 122, the outer side wall 123, the speaker unit 2 and the upper shell 11 on both sides of the speaker unit 2 together form a front sound chamber of the speaker module, and the front sound chamber of the speaker module communicates with the sound hole 10.
- the inverted tube formed between the 122 and the outer side wall 123 forms the other open end of the inverter tube at the edge of the speaker unit 2, and the open end communicates with the front acoustic chamber of the speaker module.
- the sound wave of the sound chamber of the speaker module enters the inverted tube through the open end 120, and the sound wave passes through the inverted tube and enters the front sound chamber through the open end of the inverted tube on the side of the front sound chamber, and then radiates to the outside through the front sound chamber, that is,
- the sound wave radiated from the rear side of the diaphragm is radiated to the outside through the path S2, as shown in FIG. 2 and FIG.
