Description

Technical Field

[0001] This utility model relates to the field of audio receiving devices, and in particular to a binding-type audio receiving device. Background Technology

[0002] During a performance, the sound of a piano may not be able to cover the entire audience area. By receiving the piano sound through an audio receiver and amplifying it using a sound system, it can be ensured that all audience members can hear the performance clearly. Therefore, an audio receiver needs to be placed on the piano. However, conventional methods of fixing audio receivers usually involve using adhesive materials such as double-sided tape, strong adhesive, or Velcro to fix them to the piano. These adhesive materials can contaminate the piano and are prone to falling off. Utility Model Content

[0040] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Please refer to Figures 1 to 4 This utility model provides a binding audio receiving device, including a mounting plate 1, an audio receiver 4, a strap 5, a drive wheel 8, a rotating shaft 2, and a hook 6;

[0042] One end of the mounting plate 1 is recessed inward and has a mounting groove;

[0043] The two ends of the rotating shaft 2 are rotatably mounted on the two side walls of the mounting groove, and one end of the rotating shaft 2 passes through the mounting plate 1 and extends outward, and is connected to the drive wheel 8 through a spline;

[0044] A limit rod 10 is provided on the side of the drive wheel 8 near the mounting plate 1;

[0045] The surface of the mounting plate 1 is provided with a plurality of limiting holes 9 corresponding to the limiting rod 10 arranged in a circular array with the rotating shaft 2 as the center;

[0046] The bottom of the mounting plate 1 is provided with a hook 6;

[0047] The strap 5 is wound around the shaft 2, and the strap 5 has several hanging holes that are equally spaced along its length and are adapted to the hook 6.

[0048] The inner wall of the mounting groove is provided with a strap outlet hole corresponding to the strap 5;

[0049] In use, rotate the drive wheel 8 to drive the rotating shaft 2 to rotate via the spline, unwinding the strap 5. When the strap 5 is long enough, slide the drive wheel 8 so that the limiting rod 10 on the drive wheel 8 enters the limiting hole 9 to fix the rotating shaft 2. Then, wrap the strap 5 around the rod-shaped part on the piano leg or the inner wall of the piano and select the corresponding hanging hole on the strap 5 to connect the hook 6 to quickly fix the audio receiver 4 without causing any damage to the piano. This method is suitable for large-scale promotion and use.

[0050] In this embodiment, a limit block 7 is provided at one end of the rotating shaft 2 where the drive wheel 8 is mounted.

[0051] In this embodiment, a rotating mechanism 3 is also included. The rotating mechanism 3 is installed on the upper surface of the mounting plate 1, and the audio receiver 4 is installed on the rotating end of the rotating mechanism 3. The rotating mechanism 3 includes a base 31, a rotating seat 32, and a fastening bolt 33.

[0052] The upper surface of the base 31 is recessed with a rotating groove;

[0053] Rotary seat 32 is rotatably mounted in the rotating slot;

[0054] The outer wall of the base 31 is provided with a threaded hole, and a fastening bolt 33 is threaded into the threaded hole. Tightening the fastening bolt 33 will fix the rotator 32 in the rotating groove.

[0055] In use, the receiving direction of the audio receiver 4 can be adjusted by rotating the base 31, and then fixed by tightening the fastening bolt 33.

[0056] In this embodiment, the strap 5 is made of rubber.

[0057] The working principle of this utility model is as follows:

[0058] Rotating the drive wheel 8 drives the rotating shaft 2 to rotate via the spline, unwinding the strap 5. When the strap 5 is long enough, sliding the drive wheel 8 allows the limiting rod 10 on the drive wheel 8 to enter the limiting hole 9, thus fixing the rotating shaft 2. Then, the strap 5 is placed around the rod-shaped component on the piano leg or the inner wall of the piano. The corresponding hanging hole on the strap 5 is selected to connect the hook 6, which quickly fixes the audio receiver 4 without causing any damage to the piano, making it suitable for large-scale promotion and use.

[0059] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
