[0034] Please refer to Figures 1 to 5 The utility model embodiment provides a kind of magnetic foot pad, applied to sound box 2, magnetic foot pad includes:

[0035] Pad block body 1 is supported in one side edge foot 21 of the bottom of sound box 2;

[0036] First magnetic attraction piece 11 is arranged on pad block body 1;

[0037] Multiple second magnetic attraction pieces 12 are respectively arranged on multiple side edge feet 21 of the bottom of sound box 2.

[0038] In the embodiment, the magnetic foot pad realizes the adjustment of the attitude angle of the sound box 2 in the three-dimensional space through the innovative magnetic attraction structure.The core design of the application includes the first magnetic attraction piece 11 arranged on the pad block body 1 and the second magnetic attraction piece 12 distributed on the multiple side edge feet 21 of the bottom of the sound box 2, forming a magnetic attraction positioning system linked up and down.By disassembling the magnetic foot pad and re-adsorbing it on the side edge feet 21 of different sides of the bottom of the sound box 2, the placing angle of the sound box 2 can be flexibly adjusted.

[0039] In some preferred embodiments, side edge feet 21 are arranged on the front side and the rear side of the bottom of the sound box 2, i.e., the pad block body 1 can be supported on the front side or the rear side of the bottom of the sound box 2, so as to realize the adjustment of the inclination angle of the sound box 2 in the front-rear side direction.

[0040] In some preferred embodiments, the thickness of the pad block body 1 can affect the inclination angle of the sound box 2 in the front-rear side direction, and the thicker the thickness of the pad block body 1 is, the greater the adjusted inclination angle is.In particular, when the pad block body 1 of the embodiment is switched to support on the side edge feet 21 of the front-rear side of the bottom of the sound box 2, the inclination angle range of the sound box 2 in the rear side direction is 10°-30°.

[0041] In some specific embodiments, as shown in Figure 2 When the pad block body 1 is supported on the side edge feet 21 of the rear side of the sound box 2, the sound box 2 can be adjusted to a certain angle in the front side direction. Figure 3 When the pad block body 1 is supported on the side edge feet 21 of the front side of the sound box 2, the sound box 2 can be adjusted to a certain angle in the rear side direction.

[0042] In an embodiment, the top of the pad block body 1 is provided with a first arc surface 13, and the bottom of the side edge foot 21 is provided with a second arc surface 22; when the first arc surface 13 and the second arc surface 22 abut, they fully fit each other.

[0043] In this embodiment, the first arc surface 13 and the second arc surface 22 are matched between the cushion block body 1 and the side feet 21, which increases the contact area and improves the stability of the cushion block body 1 supporting the sound box 2. This design not only makes the connection between the cushion block body 1 and the side feet 21 not easy to fall off, but also can reduce the wear caused by uneven stress to a certain extent. At the same time, the design of the first arc surface 13 and the second arc surface 22 also makes the installation process more smooth, reducing the installation difficulty.

[0044] In an embodiment, the surfaces of the first arc surface 13 and the second arc surface 22 are provided with a silica gel layer (not shown in the figure).

[0045] In this embodiment, the silica gel layer can further enhance the fit between the first arc surface 13 and the second arc surface 22, thereby improving the support stability of the cushion block body 1 to the sound box 2. In addition, after the silica gel layers are matched with each other, they have strong friction, which can effectively prevent the sound box 2 from sliding or shifting during use. In addition, the silica gel layer also has a certain damping effect, which can reduce the vibration and noise generated by the sound box 2 to a certain extent when working.

[0046] More specifically, in addition to setting a silica gel layer on the surfaces of the first arc surface 13 and the second arc surface 22 to strengthen the support stability and prevent sliding or shifting, the entire cushion block body 1 and / or the side feet 21 can also be made of silica gel. Similarly, it also has the effect of enhancing the support stability and preventing the sound box 2 from sliding or shifting. The cushion block body 1 and / or the side feet 21 made of silica gel have good fit effect and anti-skid performance without the need for additional silica gel layer due to the good elasticity and friction of silica gel itself. At the same time, the production cost of silica gel material is relatively low, which is conducive to reducing the overall production process cost.

[0047] In an embodiment, the top of the cushion block body 1 is provided with a protruding first positioning part 14, and the bottom of the side feet 21 is provided with a recessed second positioning part 23; the first positioning part 14 and the second positioning part 23 are used to position each other when the cushion block body 1 is supported on the side feet 21 at the bottom of the sound box 2.

[0048] In this embodiment, when the cushion block body 1 is supported on the corresponding side feet 21, the protruding shape of the first positioning part 14 matches the recessed shape of the second positioning part 23, forming an accurate positioning mechanism, which not only improves the convenience of installation, but also enhances the connection stability between the cushion block body 1 and the side feet 21 of the sound box 2. This design makes the user only need to simply align the protruding first positioning part 14 with the recessed second positioning part 23 when installing the cushion block body 1, so that the first arc surface 13 and the second arc surface 22 can be quickly and fully matched, making the installation process more simple and convenient, greatly saving the installation time. The user does not need to worry about the improper placement of the cushion block body 1 affecting the stability of the sound box 2.

[0049] In an embodiment, the first magnetic member 11 is embedded inside the cushion body 1 and corresponds to the first positioning part 14; the second magnetic member 12 is embedded inside the side foot 21 and corresponds to the second positioning part 23.

[0050] In this embodiment, when the first positioning part 14 and the second positioning part 23 are correctly positioned, the first magnetic member 11 and the second magnetic member 12 are also magnetically attracted to each other, thereby further ensuring the stable connection between the cushion body 1 and the side foot 21.

[0051] In an embodiment, the first magnetic member 11 and the second magnetic member 12 each include a plurality of magnets of the same number.

[0052] In this embodiment, the specific number can be determined according to factors such as the size and weight of the cushion body 1 and the side foot 21, to ensure sufficient magnetic attraction and stability of the connection.

[0053] In an embodiment, the type of the magnet of the second magnetic member 12 is a loss-of-field electromagnet, and the second magnetic member 12 is electrically connected to a power supply module inside the sound box 2.

[0054] Alternatively, the type of the magnet of the first magnetic member 11 is a loss-of-field electromagnet, and a power supply module for supplying power to the first magnetic member 11 is arranged inside the cushion body 1.

[0055] In this embodiment, one of the first magnetic member 11 and the second magnetic member 12 is set as a loss-of-field electromagnet, and the loss-of-field electromagnet can be powered when the cushion body 1 is detached, so that the cushion body 1 and the side corner of the sound box 2 lose the magnetic attraction, and the cushion body 1 can be more quickly and conveniently detached.

[0056] In this embodiment, the second magnetic member 12 is preferably set as a loss-of-field electromagnet. Specifically, the loss-of-field electromagnet is also called a "normally closed electromagnet" or a "power-off retention electromagnet", and its working principle is opposite to that of a conventional electromagnet. Its characteristic is to maintain magnetism when not powered. When the cushion body 1 normally supports the side foot 21 of the sound box 2, the second magnetic member 12 is not powered, and at this time, the second magnetic member 12 can stably maintain the magnetic attraction with the first magnetic member 11 (which adopts a conventional electromagnet). When it is necessary to quickly detach the cushion body 1, the power supply module inside the sound box 2 can supply power to the second magnetic member 12, so that the second magnetic member 12 "loses magnetism", thereby making it very convenient to quickly detach the cushion body 1. It should be noted that the connection circuit of the second magnetic member 12 and the power supply module can be provided with a control switch for on-off switching control. The control switch can be arranged on the side of the sound box 2 for convenient operation.

[0057] The utility model discloses an audio amplifier, which comprises a cabinet, a speaker, a power supply and a magnetic foot pad.

[0058] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the utility model, and these modifications or replacements should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
