Description

Technical Field

[0001] This utility model relates to the field of silicon microphone technology, specifically a switchable silicon microphone. Background Technology

[0002] A silicon microphone is an acoustic sensor that uses MEMS technology to convert acoustic signals into electrical signals. It typically consists of a MEMS capacitive acoustic sensor, a bias voltage generator, and a signal amplifier, enabling the conversion of sound into electrical signals. Existing silicon microphones have three basic directional classifications: omnidirectional, bidirectional, and monodirectional. Omnidirectional microphones (also known as non-directional microphones) pick up sound from all directions, making them equally sensitive to sound coming from all sides. They are best suited for capturing the ambient sound of a room. Bidirectional microphones, also called figure-eight microphones, pick up sound from both sides, rather than from the front or back. Monodirectional microphones are sensitive to sound coming from only one direction.

[0003] In existing technologies, most devices require the silicon microphone to be replaced according to the actual situation during use, so that the silicon microphone can better meet the needs of actual use. However, the replacement process is complicated, which increases the workload of the staff and makes it difficult to switch silicon microphones more conveniently, thus affecting the efficiency of use.

A sliding rod is provided on the rear side of each mounting bracket, and a mounting plate is slidably mounted on the sliding rod. A silicon microphone is mounted on the mounting plate. A threaded rod is rotatably mounted on each mounting bracket, penetrating the mounting plate and threadedly connected to it. A connecting seat is provided on the lower inner wall of the housing. A contact point is provided at the bottom of each silicon microphone. The silicon microphone on the left mounting plate is an omnidirectional microphone, the silicon microphone on the middle mounting plate is a bidirectional microphone, and the silicon microphone on the right mounting plate is a unidirectional microphone. A first limiting groove is provided on the outer wall of the housing, and a slider is provided on the outer wall of each mounting bracket, slidably connected to the first limiting groove.

[0021] Example

[0022] Please see Figures 1-4 In this embodiment of the invention, a switchable silicon microphone includes a housing 1. Several mounting brackets 2 are slidably arranged inside the housing 1. A sliding rod 3 is provided on the rear side of the mounting bracket 2. A mounting plate 4 is slidably arranged on the sliding rod 3, and a silicon microphone 6 is mounted on the mounting plate 4. A threaded rod 5 is rotatably arranged on the mounting bracket 2, passing through the mounting plate 4 and threadedly connected to it. Rotating the threaded rod 5 moves the mounting plate 4 on the sliding rod 3, thereby adjusting the position of the silicon microphone 6. A connecting seat 7 is also provided on the lower inner wall of the housing 1. A contact point is provided at the bottom of the silicon microphone 6. When the mounting plate 4 moves the silicon microphone 6 up and down, the contact point at the bottom of the silicon microphone 6 contacts the connecting seat 7, thereby connecting the silicon microphone 6 to an external device and enabling the silicon microphone 6 to perform... Correspondingly, a handle 501 is provided at the top end of the threaded rod 5. By rotating the handle 501, the threaded rod 5 can be rotated, thereby moving the mounting plate 4 and thus completing the adjustment of the silicon microphone 6. In addition, the silicon microphone 6 on the left mounting plate 4 is an omnidirectional microphone, the silicon microphone 6 on the middle mounting plate 4 is a bidirectional microphone, and the silicon microphone 6 on the right mounting plate 4 is a unidirectional microphone. At this time, with the action of the sliding mounting bracket 2, the switching of the silicon microphone 6 can be achieved more quickly, so that the device can better meet the needs of actual use, thereby improving the applicability of the device and ensuring the efficiency of the device. The top of the housing 1 is also provided with a second limiting groove 102, which ensures the sliding quality of the mounting bracket 2.

[0023] The outer wall of the housing 1 is also provided with a first limiting groove 101, and the outer wall of the mounting bracket 2 is provided with a slider 8. The slider 8 is slidably connected to the first limiting groove 101. The outer wall of the housing 1 is also provided with a mounting block 9. The mounting block 9 has a cavity inside, and a sliding plate 10 is slidably arranged in the cavity. The bottom of the sliding plate 10 is provided with a right-side insertion rod 11. The slider 8 is provided with an insertion hole for use with the insertion rod 11. When the mounting bracket 2 moves the silicon microphone 6 to a suitable position, the sliding plate 10 moves the insertion rod 11, so that the insertion rod 11 is inserted into the insertion hole on the slider 8, thereby fixing the position of the mounting bracket 2, thus ensuring the connection quality between the silicon microphone 6 and the connector 7, and thus ensuring the use quality of the silicon microphone 6.

[0024] A support rod 12 is provided on the top of the slide plate 10. The support rod 12 passes through the mounting block 9 and is slidably connected to the mounting block 9. A return spring 14 is also sleeved on the outside of the support rod 12. One end of the return spring 14 is connected to the slide plate 10, and the other end of the return spring 14 is connected to the mounting block 9. Under the action of the return spring 14, the fixing quality of the insertion rod 11 to the slider 8 is guaranteed, thereby ensuring the better use quality of the silicon microphone 6. A handle 13 is provided at the top end of the support rod 12. Under the action of the handle 13, the support rod 12 can be moved, thereby releasing the insertion rod 11 from the restriction of the slider 8, thus facilitating the switching of the silicon microphone 6 by the staff. A cover plate 15 is also provided on the top of the housing 1 via a hinge. Under the action of the cover plate 15, it is convenient for the staff to inspect and maintain the silicon microphone 6 on the mounting plate 4, thereby ensuring the use efficiency of the silicon microphone 6.

[0025] In actual use, when it is necessary to switch the silicon microphone 6, the operator can slide the slider 8 to move the mounting bracket 2. After the silicon microphone 6 moves to the top of the connector 7, the operator can turn the handle 501 to move the mounting plate 4 downward using the threaded rod 5, so that the contact point on the silicon microphone 6 connects with the connector 7, thereby allowing the silicon microphone 6 to connect with external devices and perform corresponding operations. At the same time, the plug 11 is inserted into the plug hole on the slider 8 to fix the mounting bracket 2, thereby ensuring the connection quality between the silicon microphone 6 and the connector 7, thus ensuring the efficiency of the silicon microphone 6. In addition, the silicon microphone 6 on the mounting plate 4 can be inspected by opening the cover 15, thus ensuring the efficiency of the silicon microphone 6.
