[0027] The following is a detailed description of a loudspeaker with easy replacement of diaphragm according to the present invention in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, an embodiment of a loudspeaker for facilitating replacement of a diaphragm of the utility model comprises a support frame 1 and a diaphragm 2 placed above the support frame 1, wherein the support frame 1 is in a rectangular ring shape, wherein a hanging edge 3 (such as Figure 7As shown), and the hanging edge 3 is placed on the top surface of the supporting frame 1; however, in order to fix the hanging edge 3 on the diaphragm 2 on the supporting frame 1, a pair of pressing plates 6 for pressing the hanging edge 3 are provided on the supporting frame 1, and the pressing plates 6 are symmetrically arranged, and movable parts are provided on both sides of the width direction of the supporting frame 1. The pressing plates 6 are movably connected to the supporting frame 1 through the movable parts. Under the action of the movable parts, the pressing plates 6 can press or loosen the hanging edge 3 placed on the top surface of the supporting frame 1; further, the hanging edge 3 is an elastic member, and when the pressing plate 6 presses the hanging edge 3, the hanging edge 3 is fixed to the supporting frame 1, so that the diaphragm 2 is elastically connected to the supporting frame 1 through the hanging edge 3.

[0029] Specifically, the movable component includes a fixing member 7 fixedly arranged on the support frame 1 and a rotating member 8 fixedly arranged on the pressure plate 6, and the fixing member 7 is rotatably connected to the rotating member 8. With the cooperation of the fixing member 7 and the rotating member 8, the symmetrically arranged pressure plate 6 can be moved on the support frame 1, thereby achieving the tightening or loosening of the hanging edge 3. In addition, in order to ensure that the pressure plate 6 is always in a state of pressing the hanging edge 3, locking components for locking the pressure plate 6 are provided on both sides in the width direction of the supporting frame 1. When the pressure plate 6 presses the hanging edge 3, the locking components are controlled to lock the pressure plate 6, so that the pressure plate 6 is always in a state of pressing the hanging edge 3, and the diaphragm 2 is installed on the supporting frame 1; however, when the diaphragm 2 needs to be replaced, the locking components are controlled to unlock, so that the pressure plate 6 releases the hanging edge 3, and after release, the diaphragm 2 can be removed from the supporting frame 1, thereby realizing the replacement of the diaphragm 2; when the diaphragm 2 is replaced, the speaker is simple to operate, which greatly improves the replacement efficiency of the diaphragm 2, and the speaker has a simple structure, which reduces the production cost, and is suitable for mass production.

[0030] like Figure 2-3As shown, a magnetic circuit component 5 and a voice coil 4 are provided inside the support frame 1, wherein the top of the voice coil 4 is fixedly arranged with the bottom surface of the diaphragm 2, and part of the voice coil 4 is placed inside the magnetic circuit component 5; when the voice coil 4 is energized, the voice coil 4 will reciprocate under the action of the magnetic circuit component 5, and the voice coil 4 will vibrate with the diaphragm 2, thereby generating sound. Further, the magnetic circuit component 5 includes a U-shaped iron 501, a magnet 502, and a washer 503, wherein the U-shaped iron 501 includes a bottom plate and a pair of side plates fixedly arranged with the inner side walls of the support frame 1, the side plates are symmetrically arranged on both sides of the bottom plate, and together with the bottom plate, form a cavity with an opening facing upward, the magnet 502 is fixedly arranged on the bottom plate and placed in the middle of the cavity, the washer 503 is arranged on the top of the magnet 502, the U-shaped iron 4 and the washer 503 both play a role in magnetic conduction, and a magnetic gap is formed between the washer 503 and the inner side wall of the side plate, the voice coil 4 is fixedly arranged with the bottom of the diaphragm 2 and part of it is placed in the magnetic gap. The magnetic gap provides a uniform permanent magnetic field required for the movement of the voice coil 4. When current flows through the voice coil 4, an electromagnetic field is generated around the voice coil 4, and the positive pole of the voice coil 4 is attracted to the negative pole of the permanent magnetic field, and conversely, the negative pole repels from the negative pole of the permanent magnetic field. When the direction of the current in the voice coil 4 is changed to change its polarity, the magnetic force between the voice coil 4 and the permanent magnet also changes accordingly, and the direction of the current in the voice coil 4 is constantly changed, thereby pushing the voice coil 4 to move back and forth rapidly. When the voice coil 4 moves, it pushes and pulls the diaphragm 2 to perform reciprocating motion, causing the air in front of the speaker to vibrate and generate sound waves.

[0031] like Figure 4-5As shown, the locking component includes a fixed block 9 arranged on the width side of the pressure plate 6, and a pair of through holes arranged vertically upward are provided on the fixed block 9, wherein a pair of slide grooves 10 are provided on the width side of the support frame 1, and a vertically arranged guide rod 11 is provided in each slide groove 10, and in addition, a slider 13 is slidably provided on the guide rod 11, and a movable block 12 is provided on the outer side of the support frame 1, and the movable block 12 is fixedly arranged with the slider 13, under the action of the slider 13 and the guide rod 11, the movable block 12 is slidably arranged on the width side of the support frame 1, and when force is applied to the movable block 12, the movable block 12 can move up and down. Secondly, the movable block 12 is placed below the fixed block 9, and a pair of latches 14 inserted into the through holes are provided on the movable block 12. When the latches 14 are in the state of being inserted into the through holes, the pressure plate 6 is locked. However, after the movable block 12 is driven to move downward, the latches 14 are disengaged from the through holes, that is, the pressure plate 6 is unlocked. After the pressure plate 6 is moved, the diaphragm 2 can be replaced. Among them, in order to ensure that the latches 14 can always remain inserted into the through holes, a clamping component for clamping the movable block 12 is provided between the movable block 12 and the supporting frame 1. Specifically, when the latches 14 are fully inserted into the through holes, the clamping component clamps the movable block 12 to prevent the movable block 12 from automatically moving downward; then, when the movable block 12 is driven to move downward so that the latches 14 are completely disengaged from the through holes, the clamping component clamps the movable block 12 again to prevent the movable block 12 from automatically moving upward.

[0032] In addition, a spring 19 is provided on the guide rod 11, and the spring 19 is placed under the slider 13 to apply an upward thrust to the slider 13. When the latch 14 is inserted into the through hole on the fixed block 9, the spring 19 always supports the slider 13 to prevent the latch 14 from being disengaged from the through hole due to vibration when the speaker is in operation; and under the dual action of the spring 19 and the clamping component, the stability of the pressure plate 6 pressing the suspension edge 3 is improved. In addition, the force of the clamping component to clamp the movable block 12 is greater than the thrust applied to the slider 13 after the spring 19 is compressed. When the diaphragm 2 is replaced, the movable block 12 is driven to move downward. After the latch 14 is completely disengaged from the through hole, the clamping component clamps the movable block 12, and the spring 19 is compressed. In addition, a groove 1201 is also provided on the movable block 12. Under the action of the groove 1201, it is possible to better apply force to the movable block 12 to drive the movable block 12 to move up and down.

[0033] like Figure 5-6As shown, the clamping component includes a limiting groove 16 arranged on the side of the support frame 1, and a fixing seat 15 is provided on the side of the movable block 12 close to the support frame 1. The fixing seat 15 is placed in the limiting groove 16. When the movable block 12 is driven to move up and down, the fixing seat 15 slides up and down in the limiting groove 16; wherein, a pair of slots 18 arranged up and down are provided in the limiting groove 16, and a metal spring 17 for being inserted into the slot 18 is installed on the fixing seat 15. When the latch 14 is fully inserted into the through hole, the metal spring 17 is inserted into the upper slot 18, and vice versa, when the latch 14 is completely separated from the through hole, the metal spring 17 is inserted into the lower slot 18.

[0034] like Figure 7 As shown, in order to further improve the installation efficiency of the diaphragm 2, a plurality of positioning posts 20 are provided on the top surface of the support frame 1, and positioning holes corresponding to the positioning posts 20 are provided on the hanging edge 3 of the diaphragm 2. After the hanging edge 3 is placed on the support frame 1, the positioning posts 20 pass through the positioning holes on the hanging edge 3 to position the diaphragm 2, making it easier to replace the diaphragm 2. In addition, a positioning groove 21 corresponding to the positioning post 20 is provided on the side where the pressure plate 6 contacts the hanging edge 3. When the pressure plate 6 presses the hanging edge 3, the end of the positioning post 20 is placed in the positioning groove 21. When the pressure plate 6 presses the hanging edge 3, the installation effect of the diaphragm 2 is further improved under the action of the positioning posts 20.

[0035] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0036] The above contents are only preferred embodiments of the present invention.
