Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a polygonal loudspeaker basin frame. Background Art

[0002] A loudspeaker is a common transducer device that converts electrical energy into sound energy. It can be found in any electrical equipment that can make sound. A general loudspeaker consists of a magnet, a basin frame, a centering support, and a membrane folded cone paper basin. Most of the other components are supported and connected by the basin frame, so the speaker has relatively high requirements for the structural strength and rigidity of the basin frame. At the same time, the basin frame also needs to have functions such as sealing and anti-resonance.

[0003] However, most traditional speaker baskets are basically connected to the speaker and the basket by fixing them or connecting them with bolts. However, after long-term use, the bolts will rust and become inconvenient to remove, and external tools are required to remove them, which will cause inconvenience and tediousness to users in actual use. In addition, the speaker cannot be cooled during use. Long-term use in the basket will cause excessive heat to damage the internal electronic components. For this reason, we propose a polygonal speaker basket. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a polygonal speaker basin frame, which has the following beneficial effects:

[0015] 1. The polygonal speaker basin frame drives the two protective rings to move in opposite directions through the output ends of the two hydraulic telescopic rods on the two connecting blocks, so that the two protective rings and the output ends of the two hydraulic telescopic rods are respectively moved out of the two circular grooves, and then the two fixing bolts are rotated counterclockwise in the inner cavity of the threaded grooves in groups of two to be taken out, so as to release the fixation of the two U-shaped blocks from the basin frame body. After release, the speaker body is moved upward and the U-shaped blocks are synchronously moved out of the matching grooves, and the speaker body is taken out of the installation groove and separated from the basin frame body, so that the user can easily separate the speaker body from the basin frame body for replacement and maintenance, which brings convenience to the user.

[0016] 2. The polygonal speaker basket can drive the four fan blades arranged on its outer ring to rotate by the rotation of the output shaft of the electric motor, so as to blow air into the basket body, so that the speaker body can be cooled by the wind when in use. At the same time, the heat generated by the speaker body in the basket body can be quickly dissipated through multiple heat dissipation grooves, thereby achieving double heat dissipation for the speaker body, preventing the speaker body from being damaged by excessive heat when in use due to internal electronic components.

[0017] 3. The polygonal speaker basin frame can prevent the speaker body from being contaminated by dust during use through the dustproof net, which can prevent external dust from being contaminated on the speaker body, thereby preventing unnecessary damage that affects the service life; and, when the dust isolated by the dustproof net reaches a certain amount that needs to be cleaned, the dustproof net can be removed from the speaker body by twisting it counterclockwise, thereby facilitating the user to clean the dustproof net, thereby preventing the inconvenience of cleaning and the deterioration of the dustproof effect due to the non-removable nature.

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.

[0025] See also Figure 1-5 A polygonal speaker basin frame includes a basin frame body 1, a mounting groove 2 is opened on the top of the basin frame body 1, card grooves 3 are opened on both sides of the top of the basin frame body 1, a speaker body 4 is arranged in the inner cavity of the mounting groove 2, U-shaped card blocks 5 are fixedly installed on both sides of the middle of the speaker body 4, circular grooves 8 are opened on both sides of the inner wall of the mounting groove 2, connecting blocks 9 are fixedly installed on both sides of the bottom of the speaker body 4, and a hydraulic telescopic rod 10 is fixedly installed on one side of every two connecting blocks 9.

[0026] Furthermore, thread grooves 6 are provided on the top of the U-shaped block 5 and on both sides of the top of the basin frame body 1 , and the inner cavities of every two thread grooves 6 are threadedly connected with fixing bolts 7 .

[0027] Furthermore, a protective ring 11 is fixedly installed on one side of the output end of the two hydraulic telescopic rods 10, and the material of the protective ring 11 is rubber material. Advantages: the output ends of the two hydraulic telescopic rods 10 on the two connecting blocks 9 drive the two protective rings 11 to move in opposite directions, so that the two protective rings 11 and the output ends of the two hydraulic telescopic rods 10 are respectively moved out of the two circular grooves 8, and then the two fixing bolts 7 are rotated counterclockwise in the inner cavity of the threaded grooves 6 in groups of two to be taken out, and the two U-shaped blocks 5 are fixed to the basin frame body 1. After release, the speaker body 4 is moved upward and the U-shaped block 5 is synchronously moved out of the corresponding groove 3, and the speaker body 4 is taken out from the installation groove 2 and separated from the basin frame body 1, so that the user can easily separate the speaker body 4 from the basin frame body 1 for replacement and maintenance, which brings convenience to the user.

[0028] Furthermore, the top of the speaker body 4 is threadedly connected with a dustproof net 12, which has the advantages that the dustproof net 12 can prevent the speaker body 4 from being contaminated by dust during use, that is, it can prevent external dust from being contaminated on the speaker body 4, thereby preventing unnecessary damage that affects the service life; and, when the dust isolated on the dustproof net 12 reaches a certain amount that needs to be cleaned, the dustproof net 12 can be removed and separated from the speaker body 4 by twisting it counterclockwise, thereby facilitating the user to clean the dustproof net 12, thereby preventing the inconvenience of cleaning and the deterioration of the dustproof effect due to the non-removable nature.

[0029] Furthermore, two heat dissipation grooves 15 are evenly spaced around the outer ring of the basin frame body 1, and an electric motor 13 is arranged in the middle of the bottom of the basin frame body 1, and fan blades 14 are fixedly installed around the outer ring of the output shaft of the electric motor 13. Advantages: the four fan blades 14 arranged on the outer ring are driven to rotate by the rotation of the output shaft of the electric motor 13, so that air can be blown into the basin frame body 1, so that the speaker body 4 is cooled by the wind when in use. At the same time, the heat generated by the speaker body 4 in the basin frame body 1 can be quickly dissipated through the multiple heat dissipation grooves 15, so that the speaker body 4 can be doubly cooled, thereby preventing the speaker body 4 from being damaged by excessive heat when in use.

[0030] Furthermore, support legs 16 are fixedly installed around the bottom of the basin frame body 1, and the bottoms of the support legs 16 are all frosted. The advantage is that by setting the bottoms of the four support legs 16 to be frosted, the friction resistance between the four support legs 16 and the working position when supporting the basin frame body 1 can be increased, thereby preventing autonomous shaking during support, and further improving the stability of the support legs 16 when supporting the basin frame body 1.

[0031] Working principle: When in use, first, after the speaker body 4 is connected to the basin frame body 1, during use, the dustproof net 12 can prevent the speaker body 4 from being contaminated by dust during use, that is, to prevent external dust from being contaminated on the speaker body 4, thereby preventing unnecessary damage that affects the service life. At the same time, the output shaft of the electric motor 13 drives the four fan blades 14 arranged on its outer ring to rotate, which can blow air into the basin frame body 1, so that the speaker body 4 is cooled by the wind when in use. At the same time, the heat generated by the speaker body 4 in the basin frame body 1 can be quickly dissipated through a plurality of heat dissipation grooves 15, thereby achieving double heat dissipation of the speaker body 4, preventing the speaker body 4 from being damaged by excessive heat when in use. When the dust and impurities on the dustproof net 12 need to be cleaned, the dustproof net 12 can be removed and separated from the speaker body 4 by twisting it counterclockwise. And it is convenient for users to clean the dustproof net 12, thereby preventing the inconvenience of cleaning and the deterioration of dustproof effect due to the non-removable structure; when the speaker body 4 needs to be replaced or repaired, first, the two protective rings 11 are driven to move in opposite directions through the output ends of the two hydraulic telescopic rods 10 on the two connecting blocks 9, so that the two protective rings 11 and the output ends of the two hydraulic telescopic rods 10 are respectively moved out of the two circular grooves 8, and then the two fixing bolts 7 are rotated counterclockwise in the inner cavity of the threaded grooves 6 in groups of two to be taken out, and the two U-shaped blocks 5 are released from the fixing of the basin frame body 1. After release, the speaker body 4 is moved upward and the U-shaped blocks 5 are synchronously moved out of the corresponding grooves 3, and the speaker body 4 is taken out from the mounting groove 2 and separated from the basin frame body 1, so that the user can separate the speaker body 4 from the basin frame body 1 for replacement and repair, which brings convenience to the user.
