The magnet unit has one side connected to the other side of the frame.

The elastic abutting member abuts between a side of the rear cover relative to the front panel and another side of the magnet unit.

Preferably, the elastic abutting member is disposed on a side of the rear cover relative to the front panel, and includes a buffer base fixed to the rear cover, and a buffer base protrudes toward the front panel. a buffer column, and a cushion disposed at the end of the buffer column and abutting against the other side of the magnet unit.

Preferably, the elastic abutting member comprises a buffer base fixed on one side of the back cover relative to the front plate, a buffer column protruding from the buffer base toward the front plate, and a buffer column The other side of the magnet unit is placed against the cushion of the buffer column.

Preferably, the rear cover is further provided with a fixing groove for fixing the buffer base on one side of the front plate.

Preferably, the elastic cushioning member and the elastic abutting member are made of soft rubber or sponge.

Preferably, the edge of the frame is provided with at least one first through hole, and the elastic buffering member is formed with a protruding post penetrating into the first through hole corresponding to the first through hole.

The utility model has the advantages that the horn main body is combined with the elastic shell and the elastic top abutting member and the casing, which is different from the conventional screw locking method, can effectively reduce the resonance phenomenon of the horn and the casing, thereby reducing the occurrence of no The necessary noise gives the listener a better sound quality.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to FIG. 1 , an electronic device with a speaker mechanism according to the present invention is a television set, but is not limited thereto, and may be an audio device or other electronic device that needs to be equipped with a speaker.

The preferred embodiment includes a casing 1 and a horn mechanism 2 disposed in the casing 1.

The casing 1 has a front plate 11, a rear cover 12, and an accommodating space 13 surrounded by both the front plate 11 and the rear cover 12, and the accommodating space 13 is for accommodating the horn mechanism 2. A horn mounting portion 111 for the horn mechanism 2 is disposed on the inner side of the front panel 11 adjacent to the accommodating space 13, and the rear cover 12 is provided with two spaced fixing slots 121 on one side of the front panel 11.

With reference to FIG. 2, in the present embodiment, the horn mounting portion 111 has three guiding grooves 112, 113, 114 which are not connected to each other, wherein the two guiding grooves 113, 114 are elongated and relatively spaced apart. The spacing of the spacing is just enough for the horn mechanism 2 to pass snugly. The other guiding slot 112 has a U-shape opening toward the two guiding slots 113, 114, so that the horn mechanism 2 can be positioned into the guiding slot 112 to be positioned. The stable card is disposed between the guiding grooves 112, 113, and 114. Actually, the application is not limited to the above, and the shape and arrangement of the guiding groove are designed according to the size of the corresponding horn.

Referring again to FIG. 1, the horn mechanism 2 includes a horn unit 21, a magnet unit 22, and an elastic abutment member 23.

The main function of the horn unit 21 is to vibrate the surrounding air to generate sound, and the horn unit 21 includes a frame 211, a vibrating paper cone 212 disposed on one side of the frame 211, and an elastic buffering member 213 covering the edge of the frame 211. The material of the elastic buffering member 213 may be soft rubber or sponge. The edge of the frame 211, together with the elastic buffering member 213, is pushed into the guiding grooves 113, 114 from one end of the guiding grooves 113, 114 away from the guiding groove 112 toward the end of the guiding groove 112 until one side of the frame 211 is placed. The bottom of the guiding groove 112 is fixed between the guiding grooves 112, 113, 114 such that the elastic buffering member 213 is interposed between the frame 211 and the guiding grooves 112, 113, 114.

The main function of the magnet unit 22 is to cause the vibrating paper cone 212 to vibrate. One side of the magnet unit 22 is connected to the frame 211 on the other side of the vibrating paper cone 212.

The elastic abutting member 23 may be made of a soft rubber or a sponge, and includes two buffer bases 231 respectively fixed to the fixing slots 121, and two buffering columns 232 protruding from the buffer base 231 toward the front plate 11, respectively. A cushion pad 233 is provided at the end of the buffer column 232 and attached to the magnet unit 22.

Referring to FIG. 3, FIG. 4 and FIG. 5, the speaker mechanism 2 is further illustrated. In the state in which the speaker unit 21 is not covered with the elastic buffer member 213, it can be seen from FIG. 4 that the edge of the frame 211 is provided with four through holes 214, and the cushion pad 233. As shown in FIG. 5, the magnet unit 22 is attached in a circular shape, but the cushion 233 may be directly provided on the buffer column 232 without being attached to the magnet unit 22.

Referring to Figures 6 and 7, the elastic cushioning member 213 of the horn unit 21 will be described. The elastic buffering member 213 is completely covered on the edge of the frame 211 as shown in FIG. 7, and the elastic buffering member 213 is formed with four protrusions 215 respectively corresponding to the through holes 214 of the frame 211 for elastic cushioning members. The 213 is more firmly wrapped around the frame 211. However, if the through hole 214 is not provided, the elastic cushioning member 213 can be covered and fixed to the frame 211.

Referring again to Figures 1 and 2, the assembly and operation of the horn mechanism 2 of the present embodiment will be described. First, the frame 211 is inserted between the two straight-shaped guiding grooves 113, 114 by its edge, and is pressed against the other guiding groove 112, so that the elastic buffering member 213 is interposed between the frame 211 and the guiding groove 112, 113, 114, and then cover the rear cover 12 toward the front plate 11, so that the buffer column 232 abuts against the cushion 233, that is, the installation of the speaker mechanism 2 is completed. When the horn mechanism 2 starts to operate, the vibrating paper cone 212 generates front and rear vibrations, and the vibration energy is transmitted to the periphery; at this time, the horn unit 21 is fixed in the screwless manner by the guiding grooves 112, 113, 114 of the embodiment. The vibration of the horn unit 21 and the magnet unit 22 is absorbed on the front plate 11 and the elastic absorbing member 213 and the elastic abutting member 23, thereby effectively reducing the vibration energy transmission of the horn unit 21 and the magnet unit 22 to the casing 1 to reduce the casing. 1 Unnecessary noise due to resonance.

In summary, the design of the guiding groove 112, 113, 114 of the present invention, and the elastic cushioning member 213 covering the edge of the frame 211 and the elastic abutting member 23 abutting between the magnet unit 22 and the rear cover 12 In addition to fixing the speaker unit 21 to the front plate 11 without screws, the resonance between the casing 1 and the horn mechanism 2 can be effectively reduced, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
