Description

Technical Field

[0001] The utility model belongs to the technical field of playback equipment, and in particular relates to a vibration-damping foot pad and a speaker. Background Art

[0002] Audio refers to a system of devices used for sound reproduction and amplification, primarily consisting of speakers, amplifiers, sound sources, and audio processors. Speakers, based on the principle of electromagnetic induction vibration, can convert amplified electrical signals into sound waves. The main components of speakers that convert electrical energy into sound energy include magnets, coils, and vibrating membranes. During the energy conversion process, the magnet provides a stable magnetic field, current flows through the coil, and a magnetic field is generated around the coil. This magnetic field interacts with the magnetic field generated by the magnet to apply force to the coil. The vibrating membrane converts the force applied to the coil into vibrations, which in turn pushes the air to generate sound waves.

[0003] The high-frequency vibrations of the diaphragm in a speaker can cause displacement during playback. In severe cases, the speaker may fall from a table, causing damage. To ensure stability and achieve vibration reduction, a vibration-damping assembly can be installed on the bottom of the speaker. The vibration-damping assembly includes an elastic member and rubber feet. The elastic member is installed on the bottom of the speaker, and the rubber feet are installed on the side of the elastic member away from the speaker.

[0004] However, the existing vibration reduction components have a complex structure and are not easy to disassemble, assemble or replace. Utility Model Content

[0005] In order to address the deficiencies of the prior art, the present invention provides a vibration-damping foot pad and a speaker. The elastic protrusions sense gravity during vibration. The elastic protrusions squeeze the air in the vibration-damping cavity through the elastic arms. The elastic arms deform in the vibration-damping cavity to achieve a vibration-damping effect. The vibration-damping foot pad has a simple structure and is easy to disassemble and replace.

[0006] The technical effects to be achieved by the present invention are achieved through the following technical aspects:

[0007] In the first aspect, the utility model provides a vibration-damping foot pad, comprising: an elastic arm, comprising a vibration-damping surface and a fitting surface for fitting with an object to be vibration-damped, the fitting surface being recessed into the interior of the elastic arm to form a vibration-damping cavity; and an elastic protrusion, arranged on the vibration-damping surface, the elastic protrusion being arranged corresponding to the vibration-damping cavity.

[0008] In some implementations, a reinforcing rib is provided between the elastic protrusion and the elastic arm, and the reinforcing rib is arranged around the outside of the elastic protrusion.

[0009] In some implementations, the cross-sectional width of the vibration-damping cavity is greater than the cross-sectional width of the elastic protrusion.

[0010] In some implementations, the vibration-damping cavity includes a bottom wall, the bottom wall is arranged opposite to the elastic protrusion, and the bottom wall is a plane or a curved surface.

[0011] In some implementations, a plurality of elastic protrusions are provided, and the plurality of elastic protrusions are arranged at intervals on the vibration-damping surface.

[0012] In some implementations, the elastic arm includes a vibration-damping section and a connecting section, and the vibration-damping cavity and the elastic protrusion are both provided in the vibration-damping section.

[0013] In some implementations, the elastic arm defines an inner cavity in the middle of the connecting section, and the vibration-damping cavity is communicated with the inner cavity.

[0014] In a second aspect, the utility model provides a speaker comprising a housing and the aforementioned vibration-damping pad, wherein the vibration-damping pad is arranged on the housing, wherein the fitting surface fits with the outer wall of the housing.

[0015] In some implementations, the housing includes a shell and a base, the base is provided with a mounting hole, the base is detachably connected to the shell at the mounting hole, the vibration-damping foot pad is arranged on the base, and the elastic protrusion is arranged opposite to the mounting hole.

[0016] In some implementations, the elastic arm is disposed along an edge of the base.

[0017] In summary, the present invention has at least the following advantages:

[0018] 1. The vibration-damping foot pad provided by this utility model is placed in contact with the object to be damped. When vibration occurs, the elastic protrusions sense gravity and, under the action of the vibration, squeeze the spring arm in the vibration-damping cavity. The air in the vibration-damping cavity is compressed, and the spring arm deforms in the vibration-damping cavity to offset the vibration. The spring arm then returns to its original shape, achieving an excellent vibration-damping effect. The elastic protrusions achieve vibration-damping effects by deforming the spring arm in the vibration-damping cavity. The elastic protrusions and spring arm have a simple structure and can be easily disassembled and replaced.

[0019] 2. The speaker provided by the present invention has an outer wall of the shell fitted with the fitting surface, so that the vibration-damping cavity becomes a sealed cavity.

[0030] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see the attached Figure 1-3 The vibration-damping foot pad of the present invention includes an elastic arm 1, a vibration-damping cavity 13 is opened on the elastic arm 1, and an elastic protrusion 2 is provided on the elastic arm 1 corresponding to the vibration-damping cavity 13, which can play a good vibration-damping role. The elastic arm 1 and the elastic protrusion 2 have a simple structure and are easy to disassemble and assemble.

[0034] Please see the attached Figure 1 and Figure 3 The elastic arm 1 is preferably, but not limited to, a silicone pad, a rubber pad, or a TPE pad. The elastic arm 1 includes a vibration-damping surface 11 and a fitting surface 12. The fitting surface 12 is used to fit the object to be vibration-damped. The vibration-damping cavity 13 is a cavity formed by the fitting surface 12 being recessed into the interior of the elastic arm 1. The elastic protrusion 2 is arranged on the vibration-damping surface 11 and corresponds to the vibration-damping cavity 13. When the vibration-damping foot pad is placed on a flat surface such as a table, the elastic protrusion 2 contacts the table. Specifically, the vertical distance h from the contact point of the elastic protrusion 2 with the table to the vibration-damping surface 11 is the thickness of the elastic protrusion 2. The thickness h of the elastic protrusion 2 can be 40 to 70 mm. The elastic protrusion 2 can provide good support.

[0035] Please see the attached Figure 2 and Figure 3 In some specific embodiments shown, the vibration-damping cavity 13 includes a bottom wall 131, which is arranged opposite the elastic protrusion 2. During vibration, the elastic protrusion 2 senses gravity and compresses the elastic arm 1, causing the inner wall of the vibration-damping cavity 13 to deform toward the interior of the vibration-damping cavity 13, thereby compressing the air within the vibration-damping cavity 13. The bottom wall 131 can be flat or curved. Specifically, when the bottom wall 131 is curved, it can be recessed toward the elastic protrusion 2 to increase the deformation space of the elastic arm 1 in the vibration-damping cavity 13. In a preferred embodiment, the cross-sectional width of the vibration-damping cavity 13 is a, and the cross-sectional width of the elastic protrusion 2 is b, where a>b. Specifically, the cross-sectional width a of the vibration-damping cavity 13 can be 50-80 mm, and the cross-sectional width of the elastic protrusion 2 can be 20-30 mm. It will be understood that this does not specifically limit the dimensions of the vibration-damping cavity 13 and the elastic protrusion 2, and those skilled in the art can adjust them according to the specifications of the actual vibration-damping foot pad.

[0036] Please see the attached Figure 1-3 In a preferred embodiment, a plurality of elastic protrusions 2 are provided. Specifically, two elastic protrusions 2 can be provided, and the two elastic protrusions 2 are respectively located at the two ends of the elastic arm 1 along the length direction. This is not a specific limitation on the number of elastic protrusions 2. In other specific embodiments, three elastic protrusions 2 can also be provided. Multiple elastic protrusions 2 are arranged at intervals on the vibration damping surface 11 to ensure the stability of the vibration damping foot pad when it is placed.

[0037] The elastic protrusion 2 is in contact with the desktop. When the vibration force squeezes the elastic arm 1 and the elastic protrusion 2 downward, the elastic protrusion 2 is squeezed into the vibration-damping cavity 13 by gravity. The elastic arm 1 is deformed at the vibration-damping cavity 13, and the air in the vibration-damping cavity 13 is compressed to offset the downward vibration force during the vibration process; when the vibration force squeezes the elastic arm 1 and the elastic protrusion 2 upward, the elastic arm 1 and the elastic protrusion 2 rebound to their original shape, thereby offsetting the upward vibration force. The elastic arm 1 and the elastic protrusion 2 complete a vibration reduction cycle, which repeats over and over again. The vibration-damping foot pad has a good vibration reduction effect, and the structure is simple, which is convenient for disassembly and assembly of the vibration-damping foot pad, and the vibration-damping foot pad can be quickly replaced.

[0038] Example 2:

[0039] The difference between this embodiment and embodiment 1 is that, see Figure 4 In this embodiment, the inner wall of the vibration damping cavity 13 is provided with inner protrusions. As shown in some specific embodiments, the inner protrusions can be circular bumps. Multiple inner protrusions can be provided, and the multiple inner protrusions are spaced apart on the inner wall of the vibration damping cavity 13. The inner protrusions deform during vibration, which helps absorb vibration energy, reduce vibration propagation, and further enhance the vibration damping effect of the elastic arm 1. Specifically, the protrusions on opposite sides of the vibration damping cavity 13 are staggered. The elastic arm 1 compresses the air in the vibration damping cavity 13 through the inner protrusions, thereby forming an effective vibration damping assembly.

[0040] In a preferred embodiment, the elastic arm 1 is provided with a raised ring 22 on the vibration-damping surface 11. Specifically, the raised ring 22 can be a hollow cylinder, preferably, but not limited to, a rubber cylinder, a silicone cylinder, or the like. Multiple raised rings 22 can be provided, with multiple raised rings 22 arranged around the outer side of the elastic protrusion 2. During vibration, the protrusion may deform and distort under the action of vibration. The provision of the raised ring 22 balances the vibration-damping foot pad to improve stability during vibration. The deformation also assists the elastic protrusion 2 in squeezing the elastic arm 1, enhancing the vibration-damping effect. In some illustrated embodiments, the height of the raised ring 22 is less than or equal to the thickness of the elastic protrusion 2.

[0041] In a preferred embodiment, the elastic arm 1 includes a connecting section 15 and a vibration-damping section 14, the elastic protrusion 2 is arranged in the vibration-damping section 14, the vibration-damping cavity 13 is opened in the vibration-damping section 14, and the elastic arm 1 is provided with an inner cavity inside the vibration-damping section 14, and the vibration-damping cavity 13 is connected to the inner cavity. The opening of the inner cavity is conducive to the elastic arm 1 to further absorb vibration energy, wherein the inner protrusion can be arranged on the inner wall of the vibration-damping cavity 13 and the inner wall of the inner cavity.

[0042] The arrangement of the inner protrusion and the protruding ring 22 of the elastic arm 1 is conducive to further optimizing the structure of the vibration-damping foot pad, so that the vibration-damping foot pad has a better vibration-damping effect in irregular high-frequency vibrations.

[0043] Example 3:

[0044] This embodiment provides a sound system based on the above embodiment. Figure 5 and Figure 6 .

[0045] A speaker includes a shell 3 and the above-mentioned vibration-damping foot pad, wherein the fitting surface 12 of the elastic arm 1 fits with the outer wall of the shell 3. Specifically, an adhesive layer may be provided on the fitting surface 12, and the fitting surface 12 is bonded to the outer wall of the shell 3 through the adhesive layer.

[0046] In a preferred embodiment, the housing 3 includes a shell 31 and a base 32. Specifically, components such as a speaker, an amplifier and an audio processor are provided in the shell 31. It can be understood that the way in which the audio system amplifies and restores sound through the above-mentioned components is known to those skilled in the art and is achievable, and is not described in detail in this embodiment.

[0047] In some of the illustrated embodiments, the base 32 is provided with a mounting hole 321. The base 32 can be removably connected to the housing 31 at the mounting hole 321. The base 32 and the housing 31 are preferably assembled using, but not limited to, screws. The base 32 is provided with screws through the mounting hole 321 and is connected to the housing 31 via the screws. A vibration-damping foot pad is provided on the base 32, wherein the elastic protrusion 2 is arranged opposite the mounting hole 321. The elastic protrusion 2 cooperates with the elastic arm 1 to achieve a good vibration-damping effect at the mounting hole 321, thereby ensuring the stable installation of the base 32 and the housing 31.

[0048] In a preferred embodiment, a mounting groove 322 is provided on the base 32. Specifically, the mounting groove 322 is adapted to the elastic arm 1, and the mounting hole 321 is provided on the inner wall of the mounting groove 322. The vibration-damping foot pad is provided in the mounting groove 322, which is beneficial to increase the contact area between the base 32 and the desktop, thereby ensuring the stability of the sound during vibration.

[0049] In a preferred embodiment, the elastic arm 1 is disposed along the edge of the base 32. Specifically, the elastic arm 1 can be an arc-shaped elastic pad that adapts to the edge of the base 32. It is understood that this is not the only limitation on the shape of the elastic arm 1. In other specific embodiments, the elastic arm 1 can also be an elongated or annular shape. The placement of the elastic arm 1 along the edge of the base 32 helps increase the contact area between the elastic arm 1 and the desktop when deforming, thereby improving the vibration reduction effect on the speaker and ensuring the stability of the speaker during playback.

[0050] The vibration-damping foot pads are set on the base, which helps to improve the phenomenon of the speaker falling due to vibration displacement during playback, and can improve the safety and convenience of using the speaker.
