Description

Technical Field

[0001] The invention belongs to the technical field of speaker grille installation, and in particular relates to a speaker grille pressing device. Background Art

[0002] In order to protect the exposed speaker unit and meet the appearance requirements, a grille is usually provided on the speaker. After the grille is connected to the speaker body, it covers the speaker unit, thereby protecting the speaker unit and having a good appearance, and at the same time improving the sound quality of the speaker. At present, the grille is fixed to the speaker body with screws, which has the advantage of reliable connection and the disadvantage of inconvenience in removal. Another way is that the grille is connected to the speaker body with a buckle, which has the advantage of easy removal.

[0003] However, when the audio system is fastened to the speaker body with buckles, a plurality of buckles will be evenly arranged on the fastening surface of the speaker body, and a plurality of corresponding slots will be arranged on the mesh. The mesh will be fixed by the buckles and the slots. In order to ensure the stability of the mesh connection to the speaker body, the buckles are usually composed of a structure with a certain elasticity. When the mesh is pressed onto the speaker body, the side walls of the slots will push the buckles to form a certain deformation until the buckles fall into the slots. Then the buckles will return to their original state and be tightly fastened with the slots. It is precisely because the buckles need to be interference fit with the slots during the installation process to ensure the fastening effect of the buckles and the slots.

[0004] However, since the existing grille structure has a certain curvature and is relatively thin, when installing the grille on the speaker body, if the force applied to the grille is too small, it will be difficult to snap the grille onto the speaker body. If the force applied is too large, it will easily cause the structure of the grille to change, thereby affecting the sound quality of the speaker. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] See also Figure 1-Figure 2The present embodiment provides a speaker grille pressing device, comprising an upper template 1, a lower template 2, a fixing plate 3, a guide column 4 and a buffer spring 5, a speaker profiling groove 31 is provided on the top surface of the fixing plate 3, and a grille profiling groove 21 is provided on the top surface of the lower template 2, wherein the speaker profiling groove 31 is used to define the position of the speaker body 6 on the fixing plate 3, and the grille profiling groove 21 is used to define the position of the grille 7 on the lower template 2, and when the upper template 1 is pressed on the fixing plate 3, an installation cavity is formed between the upper template 1 and the fixing plate 3, and the speaker body 6 is stably installed on the speaker profiling groove 31 through the installation cavity, the guide column 4 is installed on the top surface of the lower template 2, the spring is sleeved on the guide column 4, and the bottom surface of the fixing plate 3 is provided. A guide hole 22 is opened, and the fixing plate 3 can be slidably connected to the guide column 4 through the guide hole 22. When the face mesh 7 is installed on the speaker body 6, the face mesh 7 is placed in the face mesh profiling groove 21, and then the fixing plate 3 is placed above the lower template 2 through the cooperation of the guide hole 22 and the guide column 4, and is suspended on the lower template 2 through the buffer spring 5, and then the speaker body 6 is placed in the speaker profiling groove 31, and then the lower template 2 is buckled, and then the lower template 2 is pressed down to abut the speaker body 6 with the face mesh 7, so that the buckles on the speaker body 6 can abut against the side walls of the slot on the face mesh 7 at the same time, and then in the process of continuous downward pressure of the lower template 2, all the buckles can be simultaneously connected with the slot.

[0023] Under the restriction of the lower template 2 and the fixing plate 3, the speaker body 6 can be pressed so that all the buckles can be snapped into the slots at the same time, and because the buckles and the slots are snapped into place with an interference fit, once the face grille 7 is connected to the speaker body 6, some buckles are snapped into place first, and the remaining buckles will be dragged by the buckles that have been snapped into place, resulting in the buckles that have not been snapped into place being much more difficult to snap into place than the buckles that have been snapped into place. Allowing all the buckles to snap into place with the slots at the same time can ensure that the interference fit between the buckles and the slots is within the designed range, thereby avoiding the situation where once any buckle is snapped into place first, the interference between the remaining buckles and the slots will increase when the buckle is snapped into place, thereby avoiding the situation where the structure of the face grille 7 is changed or the installation cannot be completed smoothly due to the inability to accurately control the installation force when installing the face grille 7 on the speaker body 6.

[0024] In order to ensure the stability of the guide column 4 when providing guidance for the fixed plate 3 for a long time and not to cause shaking due to long-term use, thereby affecting the accuracy of the fixed plate 3 and the lower template 2 when being pressed together, in this embodiment, a plurality of stepped holes are opened on the top surface of the lower template 2, and the guide column 4 is installed in the stepped hole. The bottom surface of the spring abuts against the stepped surface of the stepped hole. By opening a stepped hole on the top surface of the lower template 2, the bottom of the guide column 4 is located in the stepped hole, so that the guide column 4 can ensure stability under the restriction of the side wall of the stepped hole. At the same time, the cooperation between the guide column 4 and the side wall of the stepped hole can reduce the shaking of the guide column 4 during long-term use.

[0025] In order to ensure that the position of the speaker body 6 can be limited without causing shaking when the upper template 1 is pressed on the fixing plate 3, in one embodiment, a positioning column 11 is provided on the bottom surface of the upper template 1, and a positioning guide sleeve 32 is provided on the top surface of the fixing plate 3. When the upper template 1 is pressed, the positioning column 11 is engaged with the positioning guide sleeve 32. When the upper template 1 is pressed on the fixing plate 3, the bottom end of the positioning column 11 will be engaged with the positioning guide sleeve 32, so that when the upper template 1 is pressed on the fixing plate 3, the upper template 1 can be accurately pressed on the fixing plate 3 through the cooperation of the positioning column 11 and the positioning guide sleeve 32, so as to better limit the speaker body 6, so that the speaker body 6 will not shake or have position deviation during the pressing process, and it is ensured that the buckle of the speaker body 6 can be smoothly connected with the card slot when pressing.

[0026] Since the mesh 7 itself is easily deformed when subjected to external force, the downward pressure of the speaker body 6 will exert a certain downward pressure on the mesh 7 during the buckle connection process, and since the slot is located at the edge of the mesh 7 and the structure of the mesh 7 is arc-shaped, that is, high in the middle and low at the edge, and the mesh 7 is inverted on the top surface of the lower template 2 during the pressing process, therefore, when the buckle abuts against the side wall of the slot during the pressing process, this will cause the edge of the mesh 7 to be stressed, and at this time the main stress-bearing area of ​​the mesh 7 is located in the middle of the mesh 7, that is, the arc-shaped protrusion. Therefore, in order to ensure that the structure of the mesh 7 does not change during the pressing process and thus affect the quality of the tone, in one embodiment, a profiling column 23 is provided in the mesh profiling groove 21. The profiling column 23 is used to support the middle area of ​​the mesh 7. The profiling column 23 is used to limit the position deviation of the mesh 7 during the pressing process. At the same time, the profiling column 23 can also provide supporting force when the mesh 7 is pressed to ensure that the structure of the mesh 7 does not change.

[0027] Although the structure in the middle of the face net 7 is supported by the profiling column 23 to ensure that the arc-shaped structure in the middle of the face net 7 does not change during the pressing, the face net 7 itself is relatively thin and the buckle and the slot are connected by interference fit, so the face net 7 itself has a certain softness. During the pressing process, the force-bearing area of ​​the face net 7 is located in the area where the slot is located. After the middle of the face net 7 is supported by the profiling column 23, the edge of the face net 7 is prone to turn outward when subjected to external force. Therefore, in order to prevent the edge of the face net 7 from turning outward during the pressing process and causing the structure of the face net 7 to change, In order to prevent the occurrence of such a situation, in one embodiment, a support rod 24 is provided on the top surface of the mesh profiling groove 21 at the position corresponding to the mesh 7 slot, and a flexible layer is provided on the top surface of the support rod 24. The support rod 24 is used to provide support for the slot when the mesh 7 is pressed. By arranging the support rod 24 at the position corresponding to the slot, the support rod 24 can provide support for the force-bearing area when the mesh 7 is pressed. At the same time, the softness of the flexible layer can prevent the support rod 24 from deforming the contact position between the mesh 7 and the support rod 24 during support, and can also prevent the mesh 7 from turning outward during the pressing process, thereby preventing the structure of the mesh 7 from changing.

[0028] During the pressing process of the upper template 1, the compression spring will play a buffering role to prevent the mesh 7 from being directly subjected to a large impact force and being damaged. Since the buffering force of the compression spring depends on its own material limitations and is also affected by the number of coils of the spring, in order to prevent the spring from failing to play a buffering role due to elastic attenuation during a long period of pressing, in one embodiment, a compression rod 33 is provided on the bottom surface of the fixed plate 3, and a compression hole 25 is opened on the top surface of the lower template 2. When the upper template 1 is pressed down, the compression rod 33 slides and fits into the compression hole 25. During the pressing process of the upper template 1, the compression rod 33 squeezes the space in the compression hole 25, thereby increasing the air pressure in the compression hole 25. The smaller the volume of the compressed air, the greater the air pressure. Therefore, a reaction force is provided for the compression rod 33 by reducing the size of the space in the compression hole 25, so that the fixed plate 3 cannot fit on the top surface of the lower template 2 during pressing, thereby ensuring that the structure of the mesh 7 will not be deformed due to the failure of the spring during pressing.

[0029] In order to ensure that the support rod 24 does not shake during the pressing process, in one embodiment, a through hole 26 is opened on the top surface of the mesh contour groove 21, and the compression hole 25 is connected to the through hole 26. An air channel 241 is opened on the bottom surface of the support rod 24, and the through hole 26 is connected to the air channel 241. The through hole 26 is a stepped hole, and the bottom surface of the support rod 24 is in close contact with the stepped surface in the through hole 26, so that the support rod 24 is in close contact with the through hole 26, and the position of the support rod 24 is limited by the through hole 26, so that the support rod 24 can provide supporting force without uneven force due to the abutment with the curved surface of the mesh 7, which will cause the support rod 24 to bend, shake, etc. during continuous support.

[0030] Since the position where the card slot of the face mesh 7 is located is a curved surface, and there are small grooves on the abutting surface corresponding to the card slot, in order to ensure that the support rod 24 can provide all-round support to the position where the card slot is located during support, and to ensure the supporting effect of the support rod 24, in one embodiment, an airbag 8 is provided on the top of the airway 241, and the airbag 8 is made of a flexible material. When the space in the compression hole 25 is squeezed, the compressed gas will enter the airbag 8 through the through hole 26 and the airway 241, and the airbag 8 will be inflated and opened, thereby abutting against the face mesh 7. Since the airbag 8 is made of a flexible material, when the airbag 8 is inflated and expanded, it will fit on the curved surface of the face mesh 7, so that the face mesh 7 can be better supported by the airbag 8, thereby avoiding the situation where the supporting force of the support rod 24 is insufficient due to the complex curved surface of the face mesh 7.

[0031] In order to better improve the supporting force of the airbag 8, in one embodiment, the aperture of the compression hole 25 is larger than the aperture of the airway 241. When the aperture of the compression hole 25 is larger, the compressed space is larger and the compressed air pressure is greater, so that the airbag 8 can be filled with more gas, thereby improving the supporting force of the airbag 8 and ensuring the supporting effect of the airbag 8.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
