Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a supporting foot with adjustable multi-angle sound output directions of a loudspeaker. Background Art

[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it means that the speaker main box or subwoofer box has a built-in power amplifier, which amplifies the audio signal and then plays it back through the speaker itself, making the sound louder.

The speaker wall-mounted structure includes a speaker housing, a control circuit is arranged inside the speaker housing, the control circuit includes a long strip of sound effect control circuit board, an adjustable control element is arranged on the sound effect control circuit board, the sound effect control circuit board is placed inside the speaker housing, an adjustment roller is installed on the adjustable end of the adjustable control element, a hole is opened in the speaker housing corresponding to the adjustment roller, the rim of the adjustment roller protrudes from the surface of the speaker housing through the hole, and the rim of the adjustment roller only protrudes slightly from the surface of the speaker. When in use, the volume can be adjusted by rolling the adjustment roller clockwise or counterclockwise. The adjustment is convenient and does not affect the overall appearance of the speaker, making the entire speaker look integrated. But

[0004] The placement of speakers is suitable for different places. For speakers placed on the ground, most of the prior art, like the above patent, are placed flat on the ground, and it is difficult to adjust the sound direction, so that the sound direction can only be horizontal, and the adaptability is low.

[0023] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0024] like Figures 1 to 7 As shown, it is a schematic diagram of the structure of the support foot with adjustable multi-angle speaker sound output direction provided by the utility model. The support foot with adjustable multi-angle speaker sound output direction includes a shell 10, and at least two support foot assemblies 20 arranged on the shell 10. It can be imagined that the support foot with adjustable multi-angle speaker sound output direction also includes other functional modules, such as speakers, mounting components, and fasteners, etc., which are well known to those skilled in the art and will not be repeated here.

[0025] The shell 10 is hollow and its interior is used to place the speaker. The shell 10 includes a slope 11 and a bottom surface 12. The bottom surface 12 is in contact with the placement platform of the support foot with adjustable multi-angle speaker sound output direction and is provided with the support foot assembly 20. The angle between the slope 11 and the bottom surface 12 is an acute angle, which is 35 degrees in this embodiment. A sound outlet 13 is provided at the center of the slope 11, and the speaker inside the shell 10 transmits sound through the sound outlet 13.

[0026] The leg support assembly 20 includes a base 21 , a rotating shaft 22 rotatably disposed on the base 21 , a supporting plate 23 rotatably disposed on the base 21 , and a locking hook 24 disposed on the base 21 .

[0027] The base 21 includes a first substrate 211 , a connecting plate 212 disposed on the first substrate 211 , and a second substrate 213 disposed on the connecting plate 212 .

[0028] The centers of the first substrate 211 and the second substrate 213 are connected to the housing 10 by fasteners. The thickness of the second substrate 213 is less than that of the first substrate 211, so that after the support plate 23 is set, the thickness of the second substrate 213 is the same as that of the first substrate 211 to ensure stability when folded. A first anti-skid pad 214 is provided on the first substrate 211 to increase friction to prevent sliding and improve stability. The connecting plate 212 is inserted with a rotating shaft 22. The second substrate 213 is provided with a locking hook 24.

[0029] Two connecting parts 231 are arranged at intervals at one end of the support plate 23, and a second anti-skid pad 232 is arranged at the other end. The rotating shaft 22 is passed through the connecting part 231 and the connecting plate 212, so as to rotatably connect one end of the support plate 23. A receiving groove 233 is arranged in the middle position of the support plate 23. A through hole 234 is arranged at the center of the receiving groove 233, and a first clamping part 235 extending toward the center is arranged on a side wall of the through hole 234. The first clamping part 235 and the side wall of the through hole 234 are arranged in an arc. A third anti-skid pad 236 is arranged in the receiving groove 233, and the third anti-skid pad 236 is used to cover the through hole 234 to prevent foreign matter from entering the through hole 234, and also has the effect of improving the appearance and anti-skid.

[0030] The locking hook 24 is made of a material with a certain elasticity, such as plastic, so that it can be slightly deformed. The locking hook 24 is arranged perpendicular to the direction of the second substrate 213. When locked, the locking hook 24 is located in the through hole 234, so that it will not extend into the accommodating groove 233. A second clamping portion 241 facing the first clamping portion 235 is arranged on one side of the locking hook 24. The end of the second clamping portion 241 close to the second substrate 213 is connected to the locking hook 24 in an arc, so as to be mutually clamped with the first clamping portion 235. The end of the second clamping portion 241 close to the free end of the locking hook 24 is connected to the locking hook 24 in an inclined surface, and the inclined surface plays a guiding role when the support plate 23 is buckled. Specifically, the first clamping portion 235 slides along the inclined surface and deforms the locking hook 24 after applying force, until the second clamping portion 241 is mutually clamped with the first clamping portion 235, so as to realize the connection between the support plate 23 and the second substrate 213. When it is necessary to open, the support plate 23 is moved. Since the end of the second clamping portion 241 close to the second substrate 213 is connected to the locking hook 24 in an arc shape, the locking hook 24 can be deformed when force is applied, so that the second clamping portion 241 and the first clamping portion 235 are separated from each other. By rotating the support plate 23, one end of the support plate 23 is supported on the ground, so that one end of the shell 10 is lifted up to adjust the direction of the sound outlet 13. In addition, in order to ensure that the support plate 23 and the second substrate 213 and the shell 10 are free from collision and displacement, fourth anti-slip pads 237 are respectively provided at both ends of the end surface of the support plate 23 facing the shell 10.

[0031] Compared with the prior art, the utility model provides a support foot with adjustable multi-angle speaker sound output direction, and a first clamping portion 235 extending toward the center is provided on one side wall of the through hole 234 of the support plate 23. The first clamping portion 235 and the side wall of the through hole 234 are arranged in an arc. A second clamping portion 241 facing the first clamping portion 235 is provided on one side of the locking hook 24. The second clamping portion 241 is connected to the locking hook 24 in an arc at one end close to the second substrate 213, so as to be mutually clamped with the first clamping portion 235 to realize the flat placement of the speaker. At the same time, the locking hook 24 can be deformed when force is applied, so that the second clamping portion 241 and the first clamping portion 235 are separated from each other. By rotating the support plate 23, one end of which is supported on the ground, one end of the housing 10 is lifted up to adjust the direction of the sound outlet 13.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
