[0002] A speaker is a transducer device that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but it is also the most important component for the sound effect. There are many types of speakers, and the prices vary greatly. Audio electrical energy vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects and resonates (resonates) with the surrounding air to produce sound.

[0003] Existing speakers have certain shortcomings. Most of the speaker diaphragms are fixed by colloid adhesion. External dust can easily be fixed on the filter screen or diaphragm set inside the speaker. It is also inconvenient to disassemble the speaker diaphragm and filter screen. It is difficult to repair the speaker diaphragm filter screen, which reduces the flexibility of disassembly.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a loudspeaker that is easy to install a diaphragm is proposed. Utility Model Content

[0012] Compared with the prior art, the beneficial effect of the utility model is that the loudspeaker with easy installation of the diaphragm can not only improve the efficiency of disassembly and installation, but also can be easily installed with diaphragms of different thicknesses.

[0013] 1. The utility model sets a fixing assembly, slides the card plate set inside the fixing ring into the card slot, and applies pressure to the pressure plate, so that the pressure plate pushes the card plate to move to the bottom of the card slot, then rotates the pressure plate and the fixing ring clockwise, and loosens the pressure on the pressure plate, and the pressure plate is pushed by the return spring to separate from the fixing ring. When the fixing ring is separated, the card plate is pulled into the innermost part of the card slot to be fixed, preventing self-rotation, thereby achieving the purpose of improving the efficiency of disassembly and installation;

[0014] 2. The utility model arranges the installation groove, the positioning ring, the protective soft rubber, the spring rod and the force ring so that after the fixing ring is installed, pressure is applied to the positioning ring placed inside the installation groove, and the positioning ring pushes the positioning ring to apply pressure to the vibration membrane through the spring rod.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 4 As shown, a speaker for facilitating installation of a diaphragm comprises a speaker housing 1 and a fixing assembly 5. A diaphragm 2 is provided inside the right side of the speaker housing 1, and a frame 3 is provided on the outer side of the speaker housing 1 corresponding to the diaphragm 2. A card slot 4 is provided on the outer wall of the frame 3. The fixing assembly 5 for controlling the quick installation and removal of the diaphragm 2 is installed on the outer wall of the frame 3. The fixing assembly 5 comprises a fixing ring 501, a movable groove 502, a card plate 503, a return spring 504 and a Hull pressure plate 505. The inner wall of the fixing ring 501 is symmetrically provided with the movable groove 502, and the card plate 503 is provided inside the movable groove 502. 03. A return spring 504 is sleeved on the outer wall of the end of the card plate 503, and a pressure plate 505 is fixedly installed on the end of the return spring 504. The card plate 503 set inside the fixing ring 501 is slid into the inside of the card slot 4, and by applying pressure to the pressure plate 505, the pressure plate 505 pushes the card plate 503 to move to the bottom of the card slot 4, and then the pressure plate 505 and the fixing ring 501 are rotated clockwise, and the pressure on the pressure plate 505 is loosened, and the pressure plate 505 is pushed by the return spring 504 to separate from the fixing ring 501. When the fixing ring 501 is separated, the card plate 503 is pulled to be fixed in the innermost part of the card slot 4.

[0022] Furthermore, a mounting groove 6 is provided inside the frame 3 , and a positioning ring 7 is placed inside the mounting groove 6 .

[0023] By adopting the above technical solution, the positioning ring 7 positions and installs the protective soft rubber 8 connected to the left side thereof.

[0024] Furthermore, a spring rod 9 is fixedly mounted on the right side of the positioning ring 7, and four groups of spring rods 9 are provided.

[0025] By adopting the above technical solution, the spring rod 9 provides a supporting force for the movement of the positioning ring 7 .

[0026] Furthermore, a force ring 10 is slidably connected to the outer wall of the spring rod 9 , and the force ring 10 is elastically connected to the positioning ring 7 through the spring rod 9 .

[0027] By adopting the above technical solution, the force ring 10 provides pressure for the positioning ring 7 to prevent the positioning ring 7 from being separated from the vibration membrane 2.

[0028] Working principle: When using the loudspeaker that is easy to install the diaphragm, first, after installing the fixing ring 501, pressure is applied to the positioning ring 7 placed inside the installation groove 6, and the positioning ring 7 pushes the positioning ring 7 to apply pressure to the diaphragm 2 through the spring rod 9. The protective soft rubber 8 set on the left side of the positioning ring 7 prevents the diaphragm 2 from sliding, thereby improving stability. The spring rod 9 can automatically adjust the position of the positioning ring 7 according to the thickness of the diaphragm 2, and then slide into the inside of the card slot 4 through the card plate 503 set inside the fixing ring 501, and pressurize the pressure plate 505 so that the pressure plate 505 pushes the card plate 503 to move to the bottom of the card slot 4, then rotate the pressure plate 505 and the fixing ring 501 clockwise, and loosen the pressure on the pressure plate 505, and the pressure plate 505 is pushed by the return spring 504 to separate from the fixing ring 501. When the fixing ring 501 is separated, the card plate 503 is pulled to be stuck in the innermost part of the card slot 4 and fixed. This is the working principle of the loudspeaker that is easy to install the diaphragm.
