Description

Technical Field

[0001] This application relates to the technical field of wireless devices, and particularly to an audio wireless transmitter. Background Art

[0002] With the development of technology and the progress of wireless transmission technology, wireless audio transmitters have been widely used in daily life and work. Traditional wireless audio transmitters usually have only one sound collection element and rely on wired charging, which to a certain extent limits the flexibility and convenience of their use. Especially in scenarios where long-term use or mobile use is required, traditional wireless audio transmitters obviously cannot meet the needs of modern users. Therefore, how to improve the use efficiency and convenience of wireless audio transmitters has become an urgent problem to be solved.

[0003] The utility model patent publication number CN210225392U discloses a wireless transmitter and a wireless receiving device matching the wireless transmitter, belonging to the communication field. The wireless transmitter of the present utility model includes a housing, a wireless transmitter circuit arranged in the housing, and a power supply module for supplying power to the wireless transmitter. An audio input interface and a transmitting antenna respectively connected to the wireless transmitter circuit are provided on the housing. The wireless transmitter further includes a control signal input structure connected to the wireless transmitter circuit. The wireless transmitter circuit synthesizes the received sound source audio signal and control signal into a modulation signal, and then transmits it through the transmitting antenna. The wireless transmitter can transmit information wirelessly, but usually the wireless transmitter is fixedly arranged, resulting in an inability to obtain information wirelessly in indoor or other areas where it is not suitable to install the wireless transmitter, reducing the application range of the wireless transmitter. Summary of the Invention

[0004] In order to solve the problem that the application scenarios of the wireless transmitter are few due to the need for fixed installation, this application provides an audio wireless transmitter.

[0005] The audio wireless transmitter provided by this application adopts the following technical solutions:

[0006] An audio wireless transmitter includes:

[0007] An installation plate having a sound collection port, a wireless transmission port, and a wireless charging port;

[0008] A transmission component including a circuit board, a sound collection component, a signal component, and a charging coil. The circuit board is installed in the installation plate, the charging coil and the sound collection component are both arranged on the circuit board, the signal component is arranged inside the installation plate and connected to the circuit board, the sound collection component is arranged corresponding to the sound collection port, the signal component is arranged corresponding to the wireless transmission port, and the charging coil corresponds to the wireless charging port;

[0009] Power supply assembly, including a battery and an electrical connection port. The battery is disposed within the mounting plate and is connected to the circuit board. The electrical connection port passes through the mounting plate and is connected to the battery.

[0010] By adopting the above technical solution, by providing a sound receiving component and a signal component within the mounting plate, the wireless transmitter can utilize the sound receiving component to obtain surrounding sounds, and convert the sounds into electrical signals. After being processed by the circuit board, the signals are transmitted to an external receiving device through the signal component. The wireless transmitter uses the mounting plate as the main body, which is convenient for placement and carrying, and can also be conveniently used in scenarios such as indoors, and can be used as a hearing aid. And by providing a charging coil within the mounting plate, while the wireless transmitter has the function of transmitting sound signals, it can use the charging coil to wirelessly charge receiving devices such as earphones, having a wide range of applications and being able to meet different usage scenarios.

[0011] Optionally, the wireless charging port is covered with a coil protective cover.

[0012] By adopting the above technical solution, the coil protective cover can protect the charging coil on the outside. Compared with the mounting plate, the coil protective cover is more conducive to transmitting magnetic force. While protecting the charging coil, it maintains efficient energy transfer during charging, improving the usage efficiency of the wireless transmitter.

[0013] Optionally, the number of sound receiving components is four, and they are evenly distributed on the circuit board, and the number of sound receiving ports correspondingly is four.

[0014] By adopting the above technical solution, the four evenly distributed sound receiving components can expand the sound receiving range of the wireless transmitter, enabling the user to receive clearer and more complete audio information, thereby improving the usage experience of the wireless transmitter.

[0015] Optionally, positioning blocks are provided on the circuit board, and positioning holes are provided on the mounting plate. The positioning blocks are connected in cooperation with the positioning holes.

[0016] By adopting the above technical solution, since the sound receiving components on the circuit board need to correspond to the sound receiving ports, and the signal components need to correspond to the wireless transmission ports, it is necessary to keep the relative positions of the circuit board and the mounting plate stable. By using the connection of the positioning blocks and the positioning holes to determine the relative positions of the circuit board and the mounting plate, the positions of the internal components of the mounting board are guaranteed to be stable.

[0017] Optionally, the number of signal components is multiple. The transmission assembly further includes a transmission strip and a transmitter. The transmitter is disposed on the circuit board, and the transmission strip sequentially connects the multiple signal components and the transmitter.

[0018] By adopting the above technical solution, the signal components are used to transmit signals to the outside world. Multiple signal components enable the wireless transmitter to transmit signals over a larger range and ensure signal stability. Since the signal components receive the electrical signals processed by the circuit board, and the circuit board only outputs electrical signals through one output port, through the transmitter and the transmission strip, the electrical signals output from one output port can be transmitted to multiple signal components, improving the transmission performance of the wireless transmitter.

[0019] Optionally, the power supply component further includes a mounting bracket, and the mounting bracket is respectively connected to the battery and the circuit board.

[0020] By adopting the above technical solution, since the battery needs to be relatively stable with respect to the circuit board, and it is difficult to directly connect the battery and the circuit board, a mounting bracket is provided so that the mounting bracket can form appropriate connections with the circuit board and the battery respectively in different connection modes, thereby ensuring the stable installation of the internal components of the wireless transmitter.

[0021] Optionally, it further includes a fixing clip, and the fixing clip is provided on the outside of the mounting plate.

[0022] By adopting the above technical solution, the fixing bracket can be used to fix the wireless transmitter, and the wireless transmitter can be fixed in some places where it cannot be placed, such as cloth-like clothes or railings, etc., improving the usage range of the wireless transmitter.

[0023] Optionally, the fixing clip is provided with a first magnet, and the mounting plate is provided with a second magnet, and the first magnet and the second magnet form an adsorption to fix the fixing clip on the outside of the mounting plate.

[0024] By adopting, the fixing bracket will make the wireless transmitter unable to be placed stably, affecting the aesthetics and being not conducive to organizing and placing it in a smaller space. Therefore, by setting the fixing clip as a detachable structure, the fixing clip can be removed when it is not needed. Fixing the fixing clip by magnetism makes the installation and removal operations of the fixing clip more convenient.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The wireless transmitter uses the mounting plate as the main body, which is convenient for placement and carrying, and can also be conveniently used in indoor scenarios and can be used as a hearing aid. And by providing a charging coil in the mounting plate, while the wireless transmitter has the function of transmitting sound signals, it can use the charging coil to wirelessly charge receiving devices such as headphones, having a large scope of application and being able to meet different usage scenarios;

[0027] 2. Multiple signal components enable the wireless transmitter to transmit signals over a larger range and ensure signal stability. The circuit board only outputs electrical signals through one output port. Through the transmitter and the transmission strip, the electrical signals output from one output port can be transmitted to multiple signal components, improving the transmission performance of the wireless transmitter.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following further describes the present application in detail with reference to the accompanying drawings.

[0034] An audio wireless transmitter, referring to Figure 1 and Figure 3 , includes a mounting disc 1, a transmission component 2, a power supply component 3, and a fixing clip 4. The mounting disc 1 is the mounting shell of the wireless transmitter. The transmission component 2 and the power supply component 3 are both mounted on the mounting disc 1. By designing it as a portable disc-shaped structure, the mounting disc 1 can be conveniently placed or carried in various occasions, so as to perform the functions of sound collection and audio transmission in various occasions. The mounting disc 1 includes a front cover 16 and a rear cover 17. By separating the front cover 16 and the rear cover 17, various electronic components can be arranged or adjusted inside the mounting disc 1. The front cover 16 is provided with a sound collection port 11, a wireless transmission port 12, and a wireless charging port 13. The wireless charging port 13 is located in the middle of the front cover 16.

Among them, the charging coil 24 is provided in the middle of the circuit board 21 corresponding to the wireless charging port 13, and a coil protective cover 5 is provided on the wireless charging port 13. The coil protective cover 5 can prevent foreign matters such as dust and liquid from entering the wireless charging port 13, and relative to the mounting plate 1, the coil protective cover 5 is more conducive to transmitting magnetic force, protecting the charging coil 24 while maintaining efficient energy transfer during charging. The number of the sound receiving components 22 is four, corresponding to the sound receiving ports 11. By providing four evenly arranged sound receiving components 22, the sound receiving range of the wireless transmitter can be increased, and the user can receive clearer and more complete audio information. The signal component 23 is connected to the front cover 16 corresponding to the wireless transmission port 12, and the back of the circuit board 21 is connected with a transmitter 26 for receiving the electrical signal processed by the circuit board 21. The transmitter 26 is connected to the signal component 23 in sequence through the transmission strip 27, so as to transmit the electrical signal output by the circuit board 21 to a plurality of signal components 23. A positioning block 25 is also provided on the circuit board 21, and a positioning port 14 is also provided on the front cover 16. The positioning block 25 and the positioning port 14 can be fitted and connected to each other. Since the sound receiving component 22 on the circuit board 21 needs to correspond to the sound receiving port 11 and the signal component 23 needs to correspond to the wireless transmission port 12, the relative positions of the circuit board 21 and the mounting plate 1 are determined by using the connection of the positioning block 25 and the positioning port 14, ensuring the stable positions of the components inside the mounting board.

[0037] Referring to Figure 3 , the power supply component 3 includes a battery 31, an electrical connection port 32, and a mounting bracket 33. The mounting bracket 33 is provided on the back of the circuit board 21. While connecting the circuit board 21, the battery 31 is fixed on the mounting bracket 33, thereby realizing the mutual fixation of the battery 31 and the mounting board. The electrical connection port 32 passes through the mounting plate 1 and is respectively connected to the battery 31 and the circuit board 21, so that the electrical connection port 32 can supply power to the battery 31 or transmit an electrical signal to the circuit board 21.

[0038] Referring to Figure 2 and Figure 3, the fixing clip 4 is provided on the outer side of the rear cover 17. A first magnet 41 is connected to the fixing clip 4, and a second magnet 15 is provided in the mounting disc 1.

[0039] The implementation principle of the embodiment of the present application is as follows: The sound signal collected by the sound receiving member 22 is processed by the circuit board 21 and then wirelessly transmitted by the signal member 23. At the same time, the charging coil 24 can wirelessly charge an external device by using the power stored in the battery 31. While being able to conveniently perform audio transmission, it can also perform wireless charging, which has better functionality.
