Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a multi-channel voltage MEMS microphone. Background Technology

[0002] MEMS (Micro-Electro-Mechanical Systems) technology, with its advantages of miniaturization, low power consumption, and high integration, has gradually become the mainstream direction in the sensor field. Against this backdrop, multi-channel voltage-type MEMS microphones have emerged. By integrating multiple MEMS microphone units onto a single chip and combining the flexibility of voltage signal output, they not only achieve synchronous acquisition and processing of sound field spatial information but also enhance target sound sources and suppress environmental interference through array algorithms. This provides efficient and low-cost solutions for scenarios such as intelligent voice interaction, professional audio acquisition, and industrial acoustic detection, becoming a key force driving innovation in audio sensing technology.

[0003] Currently, the multi-channel voltage MEMS microphones in existing technology have a fixed grip length for handheld use. This makes it difficult for users with different hand shapes and grip habits to find a comfortable grip posture, which may affect the user experience and cause fatigue during long-term use, resulting in poor practicality. In addition, existing multi-channel voltage MEMS microphones do not have a restraining mechanism when the user holds the microphone, which may cause it to fall due to unstable holding by the user, resulting in poor stability. Utility Model Content

[0004] The purpose of this invention is to solve the problems of fixed grip length in existing handheld microphones, which makes it difficult for users with different hand shapes and grip habits to find a comfortable grip posture, potentially affecting the user experience and causing fatigue during long-term use. Furthermore, the lack of a limiting mechanism when users hold the microphone can lead to it falling due to unstable grip. Therefore, this invention proposes a multi-channel voltage MEMS microphone.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-channel voltage MEMS microphone, including a microphone body, a display screen mounted on the outer wall of the microphone body, a control button mounted on one side of the display screen, an extension grip slidably connected to the inner bottom of the display screen, a drive structure for driving the extension grip to move inside the microphone body, and a strap on the outer wall of the microphone body.

[0006] Preferably, the driving structure includes a motor installed inside the microphone body, a screw fixed to the output end of the motor, the screw being threadedly connected to the extension grip, limit posts fixed at both ends of the screw on the inner wall of the microphone body, and a limit groove matching the limit posts being provided inside the extension grip.

[0007] Preferably, a support block is fixed inside the microphone body, and a dust cover is provided on the top of the support block outside the pickup end of the microphone body.

[0008] Preferably, both ends of the dust cover are fixed with a first mounting plate, and both first mounting plates are fixed to the support block by first bolts.

[0009] Preferably, a limiting plate is fixed to the bottom outer wall of the limiting post, and a limiting groove matching the limiting plate is opened inside the extending grip on the outer side of the limiting groove.

[0010] Preferably, two connecting blocks are fixed on the outer wall of the microphone body, and a second mounting plate is respectively installed on the end of the two connecting blocks away from the microphone body by a second bolt, and the strap is fixed between the two second mounting plates.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the operation of the motor drives the screw to rotate, causing the extended grip to move under the limitation of the limiting post and the limiting groove. This allows the extended grip to move outside the microphone body, thereby expanding the length of the original microphone body grip. This makes it easier for users with different hand shapes and gripping habits to find a comfortable gripping posture, thus enhancing its practicality. In addition, the device has a strap, which allows one or two fingers to pass through when the user holds the microphone body and the extended grip. The strap can limit the user's fingers to a certain extent, preventing the microphone body from falling directly when the grip is not tight, thus enhancing stability. Attached Figure Description

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a multi-channel voltage MEMS microphone, including a microphone body 1, a display screen 3 installed on the outer wall of the microphone body 1, a control button 4 installed on one side of the display screen 3, an extension grip 8 slidably connected to the inner bottom of the display screen 3, a drive structure 9 for driving the extension grip 8 to move inside the microphone body 1, and a strap 15 provided on the outer wall of the microphone body 1.

[0021] The overall effect of Embodiment 1 is that the microphone body 1 can be controlled by the control button 4, the battery level and operating level of the microphone body 1 can be displayed by the display screen 3, and the extension handle 8 can be moved by the operation of the drive structure 9. When the extension handle 8 moves outside the microphone body 1, the length of the original microphone body 1 handle is expanded, making it easier for users with different hand shapes and grip habits to find a comfortable grip posture, thus enhancing its practicality. With the strap 15, when the user holds the microphone body 1 and the extension handle 8, one or two fingers can pass through the strap 15. The strap 15 can limit the user's fingers to a certain extent, preventing the microphone body 1 from falling directly when the grip is not tight, thus enhancing stability.

[0022] Example 2, as Figure 1-4As shown, the drive structure 9 includes a motor 901 installed inside the microphone body 1. A screw 902 is fixed to the output end of the motor 901. The screw 902 is threadedly connected to the extension grip 8. Limiting posts 903 are fixed to both ends of the screw 902 on the inner wall of the microphone body 1. A limiting groove 904 matching the limiting posts 903 is provided inside the extension grip 8. A support block 2 is fixed inside the microphone body 1. A dust cover 5 is provided on the top of the support block 2 outside the pickup end of the microphone body 1. Both ends of the dust cover 5 are... A first mounting plate 6 is fixed, and both first mounting plates 6 are fixed to the support block 2 by first bolts 7. A limiting plate 10 is fixed to the bottom outer wall of the limiting post 903. A limiting groove 11 matching the limiting plate 10 is opened in the extension grip 8 on the outside of the limiting groove 904. Two connecting blocks 12 are fixed on the outer wall of the microphone body 1. The ends of the two connecting blocks 12 away from the microphone body 1 are respectively installed with second mounting plates 13 by second bolts 14. The strap 15 is fixed between the two second mounting plates 13.

[0023] The overall effect of Embodiment 2 is that the operation of the motor 901 drives the screw 902 to rotate, causing the extension grip 8 to move under the limitation of the limiting post 903 and the limiting groove 904, so that the extension grip 8 moves out of the microphone body 1, thereby expanding the length of the original microphone body 1 grip, making it easier for users with different hand shapes and grip habits to find a comfortable grip posture, thus enhancing its practicality. The second mounting plate 13 and the second bolt 14 allow for the separate installation and removal of the strap 15. When damaged, only the strap 15 needs to be replaced. The dust cover 5 further enhances the functionality of the extension grip. It can prevent dust from accumulating at the pickup end of the microphone body 1, thus improving its service life. The dust cover 5 can be installed and removed separately through the first mounting plate 6 and the first bolt 7, making it easy to clean and replace it separately. The distance that the extension grip 8 can move can be limited by the limiting plate 10 and the limiting groove 11, preventing the extension grip 8 from moving completely outside the microphone body 1. The support block 2 inside this device is equipped with a multi-channel voltage MEMS electronic chip. The control button 4 of this device can control the operation of the microphone body 1, the display screen 3 and the motor 901.

[0024] Working principle: When in use, the motor 901 drives the screw 902 to rotate, causing the extension grip 8 to move under the constraints of the limiting post 903 and the limiting groove 904. This moves the extension grip 8 outside the microphone body 1, thereby expanding the original length of the microphone body 1 grip. This allows users with different hand shapes and grip habits to find a comfortable grip, enhancing its practicality. Furthermore, the device features a strap 15, allowing one or two fingers to pass through it when the user holds the microphone body 1 and the extension grip 8. The strap 15 can... The design provides some restraint for the user's fingers, preventing the microphone body 1 from falling off when the hand is not gripping it tightly, thus enhancing stability. The second mounting plate 13 and the second bolt 14 allow for the separate installation and removal of the strap 15. When damaged, only the strap 15 needs to be replaced. The dust cover 5 prevents dust from accumulating at the pickup end of the microphone body 1, extending its lifespan. The first mounting plate 6 and the first bolt 7 also allow for the separate installation and removal of the dust cover 5, facilitating its individual cleaning and replacement.

[0025] The wiring diagrams for the control button 4, microphone body 1, display screen 3, and motor 901 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the control button 4, microphone body 1, display screen 3, and motor 901 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
