Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a transmitter and a microphone. Background Technology

[0002] A wireless microphone includes a transmitter and a receiver. The transmitter includes a housing, a PCB board, and a microphone core. The microphone core is located at the end of the housing, and the PCB board is located inside the housing. The microphone core and the solder pads of the PCB board are electrically connected by leads, which are enameled wires, with the middle part of the leads suspended in the inner cavity of the housing.

[0003] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0004] 1. In traditional wire connection methods, the wire structure occupies a certain proportion of space. Although the middle position of the wire is suspended, it will still occupy a certain amount of shell space. During use, the wireless lavalier microphone will sway and tilt with the user's body movements. When the wire touches the electrical components in the area during the swaying process, it will have a certain structural impact on the insulation layer of the wire and the electrical components.

[0005] 2. Traditional lead wires have a certain length. During long-distance transmission, audio signals will suffer some loss, resulting in damage to the original audio signal. Severe loss can even lead to serious distortion of the audio signal, affecting the microphone's sound pickup effect. Utility Model Content

[0006] This invention proposes a transmitter to solve the technical problem of lead wires occupying space in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model proposes a transmitter, including a housing, a microphone core, a PCB board, and pins;

[0008] The housing has a mounting groove and a mounting cavity. The microphone core is located in the mounting groove, the PCB board is located in the mounting cavity, the pins are located on the microphone core, and the microphone core is in contact with and electrically connected to the PCB board through the pins.

[0009] Optionally, the mounting cavity is provided with a support column and / or a support plate, and the PCB board is mounted on the support column and / or the support plate.

[0010] Optionally, the end of the support column is provided with a first positioning post, and the PCB board is provided with a positioning groove that cooperates with the first positioning post.

[0011] Optionally, the sidewall of the mounting cavity is provided with a limiting rib, and the end of the PCB board is provided with a first limiting notch that cooperates with the limiting rib.

[0012] Optionally, the transmitter further includes a control button, a limiting post is provided in the mounting cavity, a mounting hole is provided on the housing, the mounting hole communicates with the mounting cavity, the control button is installed in the mounting hole and is in contact with the PCB board, and the control button is provided with a second limiting notch that cooperates with the limiting post.

[0013] Optionally, the transmitter further includes a sponge mounting base, which is disposed on the housing and located at the microphone core. The sponge mounting base is provided with a buckle, and the housing is provided with a snap-fit ​​groove that engages with the buckle.

[0014] Optionally, the cross-section of the snap-fit ​​groove is T-shaped.

[0015] Optionally, the snap-fit ​​groove includes a first hole and a second hole, the first hole being located on a first surface of the housing and the second hole being located on a second surface of the housing, and the first hole and the second hole communicating with each other.

[0017] This utility model also proposes a microphone, including the aforementioned transmitter.

[0018] Compared with existing technologies, in the transmitter of this invention, the mounting slot is used to confine the microphone core and prevent it from becoming loose. The mounting cavity is used to confine the PCB board and prevent it from becoming loose. By using pins to connect the microphone core and the PCB board, the short pin length eliminates the space occupied by the leads, optimizes the structure, and makes the overall structure of the transmitter more compact, thus preventing pin loosening.

[0028] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Please refer to Figures 1 to 3An embodiment of this utility model provides a transmitter 100, including a housing 10, a microphone 20, a PCB board 30, and pins 40; the housing 10 is provided with a mounting groove 11 and a mounting cavity 12, the microphone 20 is disposed in the mounting groove 11, the PCB board 30 is disposed in the mounting cavity 12, and the pins 40 are disposed on the microphone 20. The microphone 20 and the PCB board 30 are abutted and electrically connected through the pins 40.

[0030] During installation, the PCB board 30 is first placed in the preset position of the mounting cavity 12, then the microphone 20 is placed in the mounting slot 11. The pins 40 of the microphone 20 are pulled out of the mounting slot 11 and extended to the solder pads of the PCB. Finally, they are soldered, thus completing the direct soldering of the pins 40 inside the housing 10. Compared with the traditional lead wire connection method, in the transmitter 100 of this embodiment, the mounting slot 11 is used to restrict the microphone 20 and prevent it from becoming loose. The mounting cavity 12 is used to restrict the PCB board 30 and prevent it from becoming loose. By using pins 40 to connect the microphone 20 and the PCB board 30 to abut and be electrically connected, the short length of the pins 40 eliminates the space occupied by the leads, optimizes the structure, and makes the overall structure of the transmitter 100 more compact, thus preventing the pins 40 from becoming loose. On the other hand, the direct soldering of the pins 40 to the PCB board 30 greatly reduces the transmission loss of the audio signal generated by the microphone 20, effectively realizes the original sound recording restoration, and improves the acoustic performance of the transmitter 100.

[0031] Furthermore, the method of mounting the microphone core 20 by soldering the pins 40 inside the housing 10 allows the housing 10 to replace a dedicated soldering fixture. The microphone core 20 does not need to be assembled after being soldered to the PCB board 30 externally. The soldering process can be performed simply by placing the microphone core 20 and the PCB board 30 in the corresponding positions. Compared with the positional deviation caused by external direct soldering, which makes it impossible for the microphone core 20 to be installed in the corresponding position of the housing 10, the direct soldering solution inside the housing 10 provided in this embodiment effectively improves the ease of installation and yield of the microphone core 20, and effectively improves the manufacturing efficiency of the transmitter 100.

By providing the first positioning column 1211 and the positioning groove 31, phenomena such as loosening of the PCB board 30 can be further avoided.

[0034] In one embodiment, the sidewall of the mounting cavity 12 is provided with a limiting rib 123, and the end of the PCB board 30 is provided with a first limiting notch 32 that cooperates with the limiting rib 123. By setting the cooperation between the limiting rib 123 and the first limiting notch 32, it is possible to further prevent the PCB board 30 from becoming loose.

[0035] In one embodiment, the transmitter 100 further includes a control button 50, and a limiting post 124 is provided in the mounting cavity 12. A mounting hole 13 is provided on the housing 10, communicating with the mounting cavity 12. The control button 50 is mounted in the mounting hole 13 and is in contact with the PCB board 30. The control button 50 has a second limiting notch 51 that cooperates with the limiting post 124. The control button 50 allows for touch operation on the PCB board 30. The mounting hole 13 is used to mount the control button 50, and the cooperation of the limiting post 124 and the second limiting notch 51 prevents the control button 50 from becoming loose.

[0036] It is understood that in some embodiments, the control button 50 can be omitted, and operation and control can be performed directly by turning the power on and off.

[0038] In one embodiment, the cross-section of the snap-fit ​​groove 14 is T-shaped. Since the snap-fit ​​groove 14 is T-shaped, it is convenient to install and lock the buckle 61 and the snap-fit ​​groove 14.
