Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker voice coils, in particular to a reinforced and anti-deformation loudspeaker voice coil. Background Art

[0002] The voice coil, defined simply as the coil of wire through which current flows, is a crucial component of the electrodynamic speaker's mechanical wave system, essentially the speaker's heart. Its performance influences the speaker's sound intensity, sound level, impedance curve, distortion, transient characteristics, speaker parameters, and sound quality, particularly its power handling capacity and lifespan. Just as heart disease is a fatal factor, speaker damage often begins with the voice coil.

[0003] Existing voice coil frames are mostly made of metal sheets, which are thinner and more fragile after processing. They are easily damaged by external and internal contact and compression. Therefore, the voice coil needs to be reinforced. Utility Model Content

[0004] The purpose of the present utility model is to provide a loudspeaker voice coil that is reinforced and prevents deformation, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a reinforced anti-deformation loudspeaker voice coil, comprising a loudspeaker voice coil body, an outer reinforcement frame, an inner reinforcement frame and a cross mounting frame,

[0006] The speaker voice coil body is respectively provided with a lead wire and a coil;

[0007] A cross mounting bracket is sleeved inside the speaker voice coil body;

[0008] The inner walls of the cross mounting frame are respectively mounted with a driving mechanism 1 and a driving mechanism 2;

[0009] The output shaft of the driving mechanism 1 is provided with a screw rod 1;

[0010] The output shaft of the second driving mechanism is provided with a second screw rod;

[0011] A fixing frame 1 is welded to the inner wall of the outer reinforcement frame;

[0012] A second fixing frame is welded to the inner wall of the inner reinforcing frame.

[0013] Preferably, the outer reinforcement frame is sleeved on the outer surface of the speaker voice coil body, and the inner reinforcement frame is sleeved on the inner wall of the speaker voice coil body. The outer reinforcement frame can support the outer surface of the speaker voice coil body, and the inner reinforcement frame can support the inner wall of the speaker voice coil body.

[0014] Preferably, a guide block 1 is welded to the end of the fixing frame 1 facing away from the outer reinforcement frame. The guide block 1 is slidably sleeved on the cross mounting frame and is threadedly mounted on the screw rod 1. The guide block 1 is slidably sleeved on the cross mounting frame to limit the position. When the guide block 1 is threadedly mounted on the screw rod 1, a person can activate the drive mechanism 1 to rotate the screw rod 1, and the guide block 1 and the fixing frame 1 can be moved left and right according to the rotation direction of the screw rod 1.

[0015] Preferably, a second guide block is welded to the end of the second fixing frame facing away from the inner reinforcement frame. The second guide block is slidably sleeved on the cross mounting frame and is threadedly mounted on the second screw rod. The second guide block is slidably sleeved on the cross mounting frame to limit the position. When the position is limited, the second guide block is threadedly mounted on the second screw rod, allowing a person to activate the second drive mechanism to rotate the second screw rod, and the second guide block and the second fixing frame can be driven to move forward and backward according to the rotation direction of the second screw rod.

[0016] Preferably, there are four drive mechanisms 1 and 2 in total, and the four drive mechanisms 1 and 2 are arranged in a rectangular array relative to the cross mounting frame. By having four drive mechanisms 1 and 2 in total, two drive mechanisms 1 and 2 are respectively formed to drive two sets of screw rods 1 and screw rods 2 to rotate.

[0017] Preferably, a total of four outer reinforcement frames and four inner reinforcement frames are provided, and the four outer reinforcement frames and four inner reinforcement frames are arranged in a rectangular array relative to the cross mounting frame. The four outer reinforcement frames and four inner reinforcement frames form a support mechanism to support the inner and outer walls of the speaker voice coil body respectively.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The present invention incorporates an external reinforcement frame. To effectively prevent accidental contact and compression of the outer wall of the speaker voice coil body when using the speaker voice coil, the cross-mounting frame can be precisely slotted into the interior of the speaker voice coil body. Once slotted, the guide block 1 is mounted on the cross-mounting frame via a sliding slot, thereby providing a position limiter. The guide block 1 is threaded onto the screw 1, enabling the operator to activate the drive mechanism 1 and drive the screw 1 for smooth rotation. Notably, the guide block 1 and the mounting frame 1 can flexibly move left and right depending on the direction of screw 1's rotation. This allows the mounting frame 1 to tightly contact and position the external reinforcement frame against the outer wall of the speaker voice coil body, effectively forming a reliable support mechanism that supports and limits the outer surface of the speaker voice coil body. This provides excellent protection against accidental contact with the external surface, preventing damage to the speaker voice coil body from direct contact.

[0020] 2. The present invention sets an inner reinforcement frame. When a person is using the loudspeaker voice coil body, in order to avoid accidental contact and squeezing of the inner wall of the loudspeaker voice coil body, the guide block 2 can be slidably sleeved on the cross mounting frame to perform a limiting operation. Specifically, the guide block 2 is mounted on the screw rod 2 by a thread, so that the person can turn on the drive mechanism 2 and drive the screw rod 2 to rotate. According to the rotation direction of the screw rod 2, the guide block 2 and the fixed frame 2 can move back and forth. In this way, the fixed frame 2 can drive the inner reinforcement frame to contact and be limited in the loudspeaker voice coil body, so that the inner reinforcement frame plays a role in supporting and limiting the inner wall of the loudspeaker voice coil body. In this way, when accidental contact or squeezing occurs from the outside, the inner reinforcement frame can be used for effective protection to avoid direct contact with the inner wall of the loudspeaker voice coil body, thereby preventing damage.

[0027] Example 1

[0029] The speaker voice coil body 1 is provided with a lead wire 3 and a coil 4;

[0030] A cross mounting bracket 6 is sleeved inside the speaker voice coil body 1;

[0031] The inner wall of the cross mounting frame 6 is respectively mounted with a driving mechanism 10 and a driving mechanism 2 11;

[0034] A fixing frame 8 is welded to the inner wall of the outer reinforcement frame 2;

[0035] A fixing frame 2 14 is welded to the inner wall of the inner reinforcing frame 5 .

[0036] As is well known to those skilled in the art, the provision of drive mechanism 1 10 and drive mechanism 2 11 is commonplace. Drive mechanism 1 10 and drive mechanism 2 11 can be powered by an external power supply such as a wire plug. During power supply, a cable external control switch can be used to control the travel of drive mechanism 1 10 and drive mechanism 2 11. These are all conventional means or common knowledge and will not be described in detail here. Those skilled in the art can make any selection based on their needs or convenience. Drive mechanism 1 10 and drive mechanism 2 11 respectively drive screw rod 1 9 and screw rod 2 12 to rotate.

[0037] The outer reinforcing frame 2 is sleeved on the outer surface of the speaker voice coil body 1, and the inner reinforcing frame 5 is sleeved on the inner wall of the speaker voice coil body 1. The outer reinforcing frame 2 can support the outer surface of the speaker voice coil body 1, and the inner reinforcing frame 5 can support the inner wall of the speaker voice coil body 1.

[0038] A guide block 7 is welded to one end of the fixing frame 8 away from the outer reinforcement frame 2. The guide block 7 is slidably sleeved on the cross mounting frame 6, and the guide block 7 is installed on the screw rod 9 through a thread. The guide block 7 is slidably sleeved on the cross mounting frame 6 to limit the position. When the guide block 7 is slidably sleeved on the cross mounting frame 6, the guide block 7 is installed on the screw rod 9 through a thread when limiting the position, so that the person can open the driving mechanism 10 to drive the screw rod 9 to rotate, and the guide block 7 and the fixing frame 8 can be driven to move left and right according to the rotation direction of the screw rod 9.

[0039] Based on Example 1: When a person is using the loudspeaker voice coil body 1, in order to support the outer wall of the loudspeaker voice coil body 1 to prevent accidental contact and squeezing, the person can sleeve the cross mounting frame 6 into the loudspeaker voice coil body 1. After sleeved, the guide block 7 is slidably sleeved on the cross mounting frame 6 for limiting the position. When limiting, the guide block 7 is installed on the screw rod 9 through a thread, so that the person can open the driving mechanism 10 to drive the screw rod 9 to rotate. According to the rotation direction of the screw rod 9, the guide block 7 and the fixing frame 8 can be driven to move left and right, so that the fixing frame 8 drives the outer reinforcement frame 2 to contact and be limited on the outer wall of the loudspeaker voice coil body 1, so that the outer reinforcement frame 2 forms a supporting mechanism to support and limit the outer surface of the loudspeaker voice coil body 1, so that when accidentally touched by the outside, it is protected by the outer reinforcement frame 2 to avoid direct contact with the loudspeaker voice coil body 1 and damage caused by damage.

[0041] like Figures 1-4 As shown, the present invention proposes a reinforced anti-deformation loudspeaker voice coil.

[0045] A screw rod 9 is provided on the output shaft of the driving mechanism 10;

[0046] The output shaft of the driving mechanism 11 is provided with a screw rod 12;

[0047] A fixing frame 8 is welded to the inner wall of the outer reinforcement frame 2;

[0048] A fixing frame 2 14 is welded to the inner wall of the inner reinforcing frame 5 .

[0049] A guide block 2 13 is welded to one end of the fixing frame 2 14 away from the inner reinforcement frame 5. The guide block 2 13 is slidably sleeved on the cross mounting frame 6, and the guide block 2 13 is installed on the screw rod 2 12 through a thread. The guide block 2 13 is slidably sleeved on the cross mounting frame 6 for limiting. When limited, the guide block 2 13 is installed on the screw rod 2 12 through a thread, so that a person can open the driving mechanism 2 11 to drive the screw rod 2 12 to rotate, and the guide block 2 13 and the fixing frame 2 14 can be driven to move forward and backward according to the rotation direction of the screw rod 2 12.

[0050] There are four drive mechanisms 1 10 and drive mechanisms 2 11 in total, and the four drive mechanisms 1 10 and drive mechanisms 2 11 are distributed in a rectangular array relative to the cross mounting frame 6. There are four drive mechanisms 1 10 and drive mechanisms 2 11 in total, thereby forming two drive mechanisms 1 10 and drive mechanisms 2 11 to respectively drive two sets of screw rods 1 9 and screw rods 2 12 to rotate.

[0051] There are four outer reinforcing frames 2 and four inner reinforcing frames 5, and the four outer reinforcing frames 2 and four inner reinforcing frames 5 are distributed in a rectangular array relative to the cross mounting frame 6. A total of four outer reinforcing frames 2 and four inner reinforcing frames 5 are provided to form a support mechanism to support the inner wall and outer wall of the speaker voice coil body 1 respectively.

[0052] Based on Example 2: When a person is using the loudspeaker voice coil body 1, in order to support the inner wall of the loudspeaker voice coil body 1 and prevent accidental contact and extrusion, the guide block 2 13 is slidably sleeved on the cross mounting frame 6 to limit the position. When limiting, the guide block 2 13 is installed on the screw rod 2 12 through a thread, so that the person can open the driving mechanism 2 11 to drive the screw rod 2 12 to rotate. According to the rotation direction of the screw rod 2 12, the guide block 2 13 and the fixing frame 2 14 can be driven to move forward and backward, so that the fixing frame 2 14 drives the inner reinforcement frame 5 to contact and limit the inner wall of the loudspeaker voice coil body 1, so that the inner reinforcement frame 5 supports and limits the inner wall of the loudspeaker voice coil body 1, so that when accidentally touched and squeezed by the outside, it is protected by the inner reinforcement frame 5 to avoid direct contact with the inner wall of the loudspeaker voice coil body 1 and causing damage.
