Description

Technical Field

[0001] This utility model relates to the field of music performance technology, and in particular to a wireless in-ear monitor with anti-feedback function suitable for music performance. Background Technology

[0002] In the field of music performance, wireless in-ear monitors have become an indispensable piece of equipment for performers. They allow performers to monitor the accompaniment, their own singing voice, and other audio signals in real time and clearly, thereby better controlling the rhythm and pitch of the performance and helping them to present a higher quality and more infectious performance effect. Anti-feedback wireless in-ear monitors are a key type of these monitors. They can effectively avoid the ear-piercing howling caused by signal feedback and other problems during the transmission of audio signals through specific technical means, which greatly protects the auditory experience at the performance site and creates a good acoustic environment for both performers and audiences.

[0003] In existing technologies, wireless in-ear monitors generally use wireless signal transmission technology. Typically, a transmitter sends the audio source signal to a receiver in the form of electromagnetic waves or other wireless methods. After receiving the signal, the receiver then transmits it to the headphones, thus achieving wireless audio transmission. For anti-feedback functions, advanced audio processing algorithms are mostly used to monitor and process audio signals in real time and accurately. When a signal that may cause feedback is detected, the frequency, amplitude, and other parameters of the signal are quickly and intelligently adjusted to suppress feedback and ensure smooth and stable audio output.

[0004] However, existing wireless earphone monitoring devices, in highly dynamic scenarios such as music performances, are prone to falling off during performers' stage movements and physical demonstrations due to the lack of a dedicated and effective fixing structure. This not only damages the device and increases usage costs but also seriously affects the performer's experience and may even interfere with the performance, negatively impacting the overall effect. Therefore, this paper proposes an anti-feedback wireless earphone monitoring device suitable for music performances to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-feedback wireless in-ear monitor suitable for music performances, aiming to improve the problem that existing wireless in-ear monitors are prone to falling off with the performer's movements in music performances and other scenarios due to the lack of an effective fixing structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wireless in-ear monitor for music performances with feedback protection includes a neckband and a transmitter. The neckband has symmetrical receivers on its sidewalls, the transmitter has a connecting cable on one side, and each receiver has an earphone on one side. The neckband has symmetrical clamping components on its outer wall.

[0008] The clamping assembly includes multiple connecting rings, each of which is slidably connected to the outer wall of the neck ring. Each connecting ring is fixedly connected to a first fixing clip, and each first fixing clip is rotatably connected to a connecting rod. Each connecting rod is rotatably connected to a second fixing clip. Anti-slip teeth are provided inside each second fixing clip and each first fixing clip. An elastic pad is provided on one side of each first fixing clip. One end of each elastic pad is fixedly connected to the inner wall of the first fixing clip, and the other end of each elastic pad is fixedly connected to the inner wall of the second fixing clip. A connecting assembly is provided on the side wall of the transmitter.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a fixing frame and a limiting ring. One side of the fixing frame is fixedly connected to the side wall of the transmitter, and the lower surface of the limiting ring is fixedly connected to the inner wall of the fixing frame.

[0011] As a further description of the above technical solution:

[0012] A support block is fixedly connected to the upper surface of the fixed frame, and a pull block is provided on the top of the support block.

[0013] As a further description of the above technical solution:

[0014] The pull block has an anti-slip groove inside, and the bottom of the pull block is fixedly connected to symmetrical connecting columns.

[0015] As a further description of the above technical solution:

[0016] Each of the connecting columns is slidably connected inside the support block and the fixing frame, and a limit ring is fixedly connected to the bottom of each connecting column.

[0017] As a further description of the above technical solution:

[0018] The second limiting ring is symmetrically arranged with the first limiting ring, and both the connecting post and the second limiting ring are semi-circular.

[0019] As a further description of the above technical solution:

[0020] Each of the connecting columns is fitted with a spring on its outer wall. One end of each spring is fixedly connected to the top of the limiting ring, and the other end of each spring is fixedly connected to the inner wall of the support block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by pressing the second fixing clip and the first fixing clip, the elastic pad is squeezed and deformed elastically, storing elastic potential energy. Then, by contacting the anti-slip teeth of the first fixing clip and the second fixing clip with the collar, the effect of adding clothing fixation to the in-ear monitor is achieved, which solves the problem that it is easy to fall off with the performer's movements during music performances. At the same time, it avoids performance interruption or equipment damage caused by the equipment falling off, and indirectly improves the continuity of the performance and the stability of the equipment.

[0023] 2. In this utility model, by pulling the pull block, the limiting ring two moves synchronously, and at the same time, the spring is squeezed to undergo elastic deformation. Then, the connecting wire is placed between the limiting ring two and the fixed frame, thereby achieving the limiting effect on the transmitter connecting wire. This solves the problem that the transmitter connecting wire is easily tangled due to lack of fixation, and the signal transmission is interrupted or the interface is loose due to pulling. It improves the stability of wireless earphone audio transmission and the reliability of equipment use. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a wireless in-ear monitor for music performances, comprising a neckband 1 and a transmitter 2. The neckband 1 has symmetrical receivers 4 on its sidewalls. The neckband 1 adopts an arc-shaped structure that conforms to the curve of the neck, with receivers 4 symmetrically positioned near the left and right ends of its sidewalls. The two receivers 4 respectively correspond to the left and right ear monitoring needs of the performer and can receive wireless audio signals in real time. A connecting cable 3 is provided on one side of the transmitter 2, which serves as the signal source connection. The connecting cable 3 extends from one side of the transmitter 2. One end of the cable 3 is stably connected to the audio input interface of the transmitter 2, and the other end can be adapted to be inserted into the output interface of external audio sources such as mixing consoles and accompaniment playback devices to achieve stable input of audio signals. Each receiver 4 is equipped with an earphone 5 on one side. The earphone 5 is connected to the audio output interface of the receiver 4 through a short cable. The earphone 5 adopts an in-ear design to enhance the sound isolation and anti-feedback effect, ensuring that the performer can clearly capture and monitor the sound. The outer wall of the neck ring 1 is equipped with symmetrical clamping components on both sides, which can fix the neck ring 1 to the collar or edge of clothing to improve the wearing stability.

[0033] The clamping assembly includes multiple connecting rings 6, each of which adopts a sliding ring structure, is fitted on the outer wall of the neck ring 1 and can be freely adjusted in position along the length of the neck ring 1, so as to facilitate the adjustment of the fixing point according to the performer's clothing style and wearing habits. Each connecting ring 6 is slidably connected to the outer wall of the neck ring 1, and a fixing clip 7 is fixedly connected to the outer wall of each connecting ring 6. A connecting rod 8 is rotatably connected inside each fixing clip 7. The length of the connecting rod 8 is adapted to the inner depth of the fixing clip 7, and it can rotate around the connection point to adjust the clamping angle.

[0034] Each connecting rod 8 has a fixed clamp 2 9 rotatably connected to its outer wall. The fixed clamp 2 9 and the fixed clamp 1 7 form a "double-layer clamping" structure. The opening direction of the fixed clamp 2 9 is the same as that of the fixed clamp 1 7, and the opening sizes of the two are matched to each other. They can clamp the clothes together to enhance the fixing force. Each fixed clamp 2 9 and fixed clamp 1 7 has anti-slip teeth 11 inside. The anti-slip teeth 11 have a fine tooth structure with even distribution, which can increase the friction with the clothing fabric. Each fixed clamp 1 7 has an elastic pad 10 on one side. One end of each elastic pad 10 is fixedly connected to the inner wall of the fixed clamp 1 7, and the other end of each elastic pad 10 is fixedly connected to the inner wall of the fixed clamp 2 9. The transmitter 2 has a connecting component on its side wall for fixing the connecting line 3.

[0035] Reference Figure 4 and Figure 5 The connecting assembly includes a fixing frame 12 and a limiting ring 13. The fixing frame 12 has a "U" shaped frame structure with its opening facing away from the transmitter 2. One side wall of the fixing frame 12 is fixedly connected to the middle of the side wall of the transmitter 2 by welding. The height of the fixing frame 12 is adapted to the diameter of the connecting line 3. The lower surface of the limiting ring 13 is fixedly connected to the inner wall of the fixing frame 12. The lower surface of the limiting ring 13 is integrally formed or connected to the bottom of the inner side of the fixing frame 12, which can support the connecting line 3 from below. A support block 14 is fixedly connected to the upper surface of the fixing frame 12. The support block 14 has a rectangular block structure and has a sliding hole adapted to the connecting post 17 inside.

[0036] The support block 14 has a pull block 15 on its top. The pull block 15 has a flat, block-like structure, and its top surface has anti-slip grooves 16. The anti-slip grooves 16 are horizontally evenly distributed strip-shaped grooves, which increase friction when the performer pinches the pull block 15 with their fingers to prevent slipping. The pull block 15 also has anti-slip grooves 16 inside. The bottom of the pull block 15 is fixedly connected to two symmetrical connecting posts 17. The two connecting posts 17 are located on both sides of the bottom of the pull block 15, and each connecting post 17 passes through the sliding hole of the support block 14 and extends to... Inside the fixed frame 12, and can slide up and down along the sliding hole, each connecting post 17 is slidably connected to the support block 14 and the fixed frame 12. Each connecting post 17 has a fixed limit ring 2 18 at the bottom. The limit ring 2 18 and the limit ring 13 are arranged symmetrically from top to bottom. They also adopt a semi-circular ring structure. Its inner diameter is the same as that of the limit ring 13. When the connecting post 17 slides down, the limit ring 2 18 can be spliced ​​with the limit ring 13 to form a complete circular ring, wrapping the connecting line 3 inside to achieve the limit.

[0037] Limiting ring 2 18 is symmetrically arranged with limiting ring 13. Both connecting post 17 and limiting ring 2 18 are semi-circular. Each connecting post 17 has a spring 19 sleeved on its outer wall. The length of the spring 19 is adapted to the length of the connecting post 17 between the support block 14 and limiting ring 2 18. One end of each spring 19 is fixedly connected to the top surface of limiting ring 2 18, and the other end is fixedly connected to the bottom inner wall of the support block 14. When the pull block 15 is pulled upward, the spring 19 is compressed and generates elastic force. After the pull block 15 is released, the elastic force of the spring 19 can push limiting ring 2 18 downward to reset, and cooperate with limiting ring 13 to complete the automatic clamping of connecting line 3. One end of each spring 19 is fixedly connected to the top of limiting ring 2 18, and the other end of each spring 19 is fixedly connected to the inner wall of the support block 14.

[0038] Working Principle: When using the modified anti-feedback wireless earphone suitable for music performances, the user first connects the transmitter 2 to an external audio source via the connecting cable 3. Then, by wearing the neck loop 1 around the user's neck, pressing the fixing clips 7 and 9 causes them to rotate and deflect on the outer wall of the connecting rod 8, thereby squeezing the elastic pad 10. This causes the elastic pad 10 to undergo elastic deformation, storing elastic potential energy. The elastic restoring force of the elastic pad 10 drives the fixing clips 7 and 9 to return to their original position, thus clamping it at the collar position. This achieves the clamping and fixing of the neck loop 1, preventing it from slipping. When the connecting wire 3 needs to be stored or restricted, the user can pull the pull block 15. Under the action of the pull, the connecting column 17 will slide inside the support block 14 and the fixing frame 12, thereby driving the second limiting ring 18 to move synchronously. The movement of the second limiting ring 18 compresses the spring 19, causing the spring 19 to undergo elastic deformation and store elastic potential energy. After the second limiting ring 18 moves, the connecting wire 3 can be placed between the fixing frame 12 and the second limiting ring 18. The elastic restoring force of the spring 19 will push the second limiting ring 18 to reset, thereby cooperating with the fixing frame 12 to achieve the fixed restriction of the connecting wire 3.
