Description

Technical Field

[0001] The utility model belongs to the technical field of speaker accessories, in particular to a speaker with magic foot pads. Background Art

[0002] In an audio system, a speaker is a key component that converts an electrical signal into sound. A woofer is specifically designed to reproduce low-frequency sounds, typically in the frequency range of 20 Hz to 200 Hz. They play an important role in multimedia experiences such as music playback, movie watching, and gaming.

[0003] During use, when the vibration frequency of the speaker approaches the natural frequency of the speaker cabinet, the vibration amplitude of the cabinet will increase significantly. This phenomenon is called resonance. When a woofer plays low-frequency sounds, it also generates a large amplitude. If the frequency of these amplitudes is close to the natural modal frequency of the speaker cabinet, resonance will be caused. When the speaker cabinet resonates, especially when a large-amplitude woofer is working, it will excite the natural mode of the cabinet. When the mode enters the rocking state, the entire cabinet will move accordingly. This movement not only consumes energy but also may cause sound distortion. Content of the Utility Model

[0004] In view of this, the utility model provides a speaker with magic foot pads that can reduce the vibration of the speaker to meet the requirements of the speaker.

[0005] A speaker with magic foot pads includes a speaker cabinet and at least one foot pad assembly provided on the speaker cabinet. The speaker cabinet includes a speaker cabinet body and at least one mounting groove provided on the speaker cabinet body. The foot pad assembly includes an energy dissipation member accommodated in the mounting groove and used for absorbing the vibration of the speaker cabinet, a foot pad heightening and anti-slip member provided on the energy dissipation member, and a fastener passing through the energy dissipation member and the foot pad heightening and anti-slip member and screwed to the speaker cabinet. The energy dissipation member is made of a flexible material, the foot pad heightening and anti-slip member is made of an anti-slip material, and the hardness of the anti-slip material is greater than that of the flexible material. When the foot pad assembly is installed in the mounting groove, the thickness of the foot pad assembly is greater than the depth in the mounting groove to heighten and protect the speaker cabinet.

[0006] Further, the anti-slip material in the foot pad heightening and anti-slip member is a hard material.

[0007] Further, the speaker cabinet further includes at least one cabinet mounting hole provided in the mounting groove.

[0008] Further, the energy dissipation member includes an energy dissipation member body, a receiving groove provided on one side of the energy dissipation member body, a first installation pipe provided on the side of the energy dissipation member body facing away from the receiving groove, and a first installation through hole penetrating through the energy dissipation member body and the first installation pipe.

[0009] Further, the side wall of the energy dissipation member body facing away from the receiving groove is wavy.

[0010] Further, the foot column heightening and anti-slip member includes a foot column heightening and anti-slip member body received in the receiving groove, anti-slip patterns provided on one side wall of the foot column heightening and anti-slip member body, a second installation pipe provided on the side of the foot column heightening and anti-slip member body facing away from the anti-slip patterns, and a second installation through hole penetrating through the foot column heightening and anti-slip member body and the second installation pipe.

[0011] Further, when the foot column assembly is installed in the installation groove, the second installation pipe is inserted into the first installation through hole, the first installation pipe is inserted into the box body installation hole, and the fasteners are sequentially arranged in the first installation through hole, the second installation through hole, and the box body installation hole.

[0012] Compared with the prior art, the speaker with magic cushion foot columns provided by the present invention prevents the vibration of the speaker box body from being conducted to the foot column heightening and anti-slip member through the energy dissipation member in the foot column assembly. Specifically, the energy dissipation member and the foot column heightening and anti-slip member are sequentially received in the installation groove in the speaker box body, and the energy dissipation member is made of a flexible material. At the same time, the hardness of the flexible material is less than the hardness of the anti-slip material used to prepare the foot column heightening and anti-slip member, so that the energy dissipation member can absorb the vibration of the speaker box body and will not transmit the vibration to the foot column heightening and anti-slip member. Furthermore, the phenomenon of the speaker box body moving when it resonates can be avoided, thereby reducing the energy loss caused thereby and the sound coloring caused by resonance, and ensuring the sound quality of the speaker.

[0016] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein is not intended to limit the protection scope of the present utility model.

[0017] As Figures 1 to 3 shown, it is a schematic structural diagram of a speaker with a magic foot post provided by the present utility model. The speaker with a magic foot post includes a speaker box body 10 and at least one foot post assembly 20 provided on the speaker box body 10. The speaker with a magic foot post also includes some other functional modules, such as an assembly component, etc., which should be well-known technologies to those skilled in the art and will not be elaborated in detail herein one by one.

[0018] The speaker box body 10 includes a speaker box body main body 11, at least one mounting groove 12 provided on the speaker box body main body 11, and at least one box body mounting hole 13 provided in the mounting groove 12. It can be understood that in Figures 1 to 3 order to facilitate drawing, only a part of the speaker box body 10 is shown. In reality, the speaker box body 10 can be a speaker box body of any structure.

[0019] The speaker box body main body 11 is used to accommodate speaker equipment, which is an existing technology in itself and will not be elaborated herein.

[0020] The number of the mounting grooves 12 is the same as the number of the foot post assemblies 20. In this embodiment, only one is shown. The mounting groove 12 is used to accommodate the foot post assembly 20 to limit the position of the foot post assembly 20. The mounting groove 12 will be described in detail below in combination with the foot post assembly 20 and will not be elaborated herein.

[0021] The number of the box body mounting holes 13 is the same as the number of the foot post assemblies 20. In this embodiment, only one is shown. The box body mounting hole 13 is used to mount the foot post assembly 20. The box body mounting hole 13 is used to cooperate with the foot post assembly 20 to facilitate the installation between the foot post assembly 20 and the speaker box body 10. Therefore, the speaker box body 10 will be described in detail below in combination with the foot post assembly 20.

[0022] The number of the foot post assemblies 20 can be set according to the size of the speaker box body 10. For a small desktop speaker, maybe only one such foot post assembly 20 is needed. For some large speakers, maybe four or six are required. Only one of them is taken as an example herein for illustration. The foot post assembly 20 includes an energy dissipation part 21 accommodated in the mounting groove 12 and used to absorb the vibration energy of the speaker box body 10, a foot post heightening and anti-slip part 22 provided on the energy dissipation part 21, and a fastener 23 penetrating through the energy dissipation part 21 and the foot post heightening and anti-slip part 22.

[0023] The energy dissipation member 21 is made of a flexible material, such as silica gel, soft plastic, soft rubber, etc., and is mainly used to absorb or prevent the vibration generated by the speaker box 10 from being transmitted to the foot column elevation and anti-slip member 22. The energy dissipation member 21 includes an energy dissipation member body 211, a receiving groove 212 provided on one side of the energy dissipation member body 211, a first mounting tube 213 provided on the side of the energy dissipation member body 211 facing away from the receiving groove 212, and a first mounting through hole 214 passing through the energy dissipation member body 211 and the first mounting tube 213.

[0024] One side wall of the energy dissipation member body 211 facing the receiving groove 212 is wavy, and this wavy structure changes the contact area between the energy dissipation member body 211 and the box body main body to change its stiffness coefficient. That is, in the processing and design process, the undulation and frequency of the wavy structure of the side wall of the energy dissipation member body 211 facing the receiving groove 212 can be designed to change the contact area between the energy dissipation member body 211 and the box body main body 11 to change its stiffness coefficient, so as to achieve the purpose of adjusting the damping of the energy dissipation member 21. Specifically, the stiffness coefficient is an index to measure the ability of a material or structure to resist deformation. In an audio system, the stiffness coefficient of the speaker box affects its response to the vibration of the speaker. The contact area between the energy dissipation member body 211 and the speaker box 10 directly affects the connection stiffness between the two. The larger the contact area between the energy dissipation member body 211 and the speaker box 10, the higher the connection stiffness, and the more sensitive the energy dissipation member body 211 is to the vibration of the speaker box 10, so that the vibration transmitted from the speaker box 10 can be absorbed as much as possible.

[0025] The receiving groove 212 is used to receive the foot column elevation and anti-slip member 22. The outer contour of the foot column elevation and anti-slip member 22 is consistent with the outer contour of the receiving groove 212, so as to facilitate the installation of the foot column elevation and anti-slip member 22 on one side of the energy dissipation member 21 and limit the position of the foot column elevation and anti-slip member 22.

[0026] The first mounting tube 213 is inserted into the box body mounting hole 13, so as to facilitate the positioning of the energy dissipation member 21 into the mounting groove 12, and at the same time increase the contact area between the energy dissipation member 21 and the speaker box 10. The first mounting tube 213 is matched with the box body mounting hole 13 to make the first mounting tube 213 stable in the box body mounting hole 13.

[0027] The first mounting through hole 214 may be a stepped hole, so that not only can the foot column elevation anti-slip member 22 be accommodated, but also the fastener 23 can be inserted, thereby facilitating the fixing of the energy dissipation member 21 and the foot column elevation anti-slip member 21 to the speaker box 10 by the fastener 23.

[0028] The foot column elevation anti-slip member 22 is made of an anti-slip material. The anti-slip material may be a hard material, such as hard rubber, hard plastic, etc. At the same time, the hardness of the anti-slip material is greater than the hardness of the flexible material, that is, the hardness of the foot column elevation anti-slip member 22 is greater than the hardness of the energy dissipation member 21, so that the foot column elevation anti-slip member 22 can support and elevate the speaker box 10 while preventing the energy of the energy dissipation member 21 from being conducted to the foot column elevation anti-slip member 22, thereby preventing the overall movement of the speaker. The foot column elevation anti-slip member 22 includes a foot column elevation anti-slip member main body 221 accommodated in the accommodation groove 212, an anti-slip pattern 222 provided on one side wall of the foot column elevation anti-slip member main body 221, a second mounting tube 223 provided on the side of the foot column elevation anti-slip member main body 221 opposite to the anti-slip pattern 222, and a second mounting through hole 224 provided on the foot column elevation anti-slip member main body 221.

[0029] The anti-slip pattern 222 is provided on the side of the foot column elevation anti-slip member main body 221 opposite to the speaker box 10 to improve the friction of the foot column elevation anti-slip member main body 221 and prevent the speaker box 10 from sliding on different contact surfaces during use. The anti-slip pattern 222 is a prior art and will not be elaborated here.

[0030] The second mounting tube 223 is inserted into the first mounting through hole 214, so that the foot column elevation anti-slip member 22 is restricted to one side of the energy dissipation member 21. The second mounting through hole 224 is used for installing the fastener. The first mounting through hole 214 and the second mounting through hole 224 are both stepped to facilitate the mutual engagement of the foot column elevation anti-slip member 22, the energy dissipation member 21, and the fastener 23. When the foot column assembly 20 is installed in the installation groove 12, the second mounting tube 223 is inserted into the first mounting through hole 214, the first mounting tube 213 is inserted into the box body mounting hole 13, and the fastener 23 is sequentially inserted into the first mounting through hole 214, the second mounting through hole 224, and the box body mounting hole 13 to fix the foot column assembly 20 and the speaker box 10 together.

[0031] The fastener 23 passes through the first mounting through-hole 214 of the energy dissipation member 21 and the second mounting through-hole 224 of the foot post heightening and anti-slip member 22. One end of the fastener 23 is connected to the connecting member in the speaker box 10, thereby realizing the fixation between the foot post assembly 20 and the speaker box 10.

[0032] Compared with the prior art, the speaker with magic foot posts provided by the present utility model prevents the vibration of the speaker box 10 from being conducted to the foot post heightening and anti-slip member 22 through the energy dissipation member 21 in the foot post assembly 20. Specifically, the energy dissipation member 21 and the foot post heightening and anti-slip member 22 are sequentially accommodated in the mounting groove 12 in the speaker box 10. The energy dissipation member 21 is made of a flexible material, and the hardness of the flexible material is less than the hardness of the anti-slip material used to prepare the foot post heightening and anti-slip member 22. Thus, the energy dissipation member 21 can absorb the vibration of the speaker box 10 and will not transmit the vibration to the foot post heightening and anti-slip member 22. Furthermore, it can avoid the phenomenon that the speaker box 10 moves when resonance occurs, thereby reducing the energy loss caused thereby and the sound coloration caused by resonance, and ensuring the sound quality of the speaker.

[0033] The above is only the preferred embodiment of the present utility model and is not used to limit the protection scope of the present utility model. Any modification, equivalent replacement or improvement within the spirit of the present utility model is covered by the scope of the claims of the present utility model.
