Description

Technical Field

[0001] The utility model relates to the technical field of voice collection equipment, in particular to a voice collection device capable of preventing sound leakage. Background Art

[0002] At present, sound is a wave generated by the vibration of an object. When an object vibrates, the surrounding narrow air is constantly compressed and relaxed and diffused to the surrounding. This is the sound wave. The frequency range of sound that people can hear is 20Hz~20kHz. The main formats of audio data are: WAVE, MOD, Layer-3, Real Audio, CD Audio, etc. There are three common methods for collecting audio data: directly obtaining existing audio, using audio processing software to capture and intercept sound, and recording sound with a microphone. Since sound collection is a technology used in many industries, it is necessary to optimize the equipment for sound collection.

[0003] For example, a voice collection device is disclosed in the Chinese utility model patent with the announcement number CN211455292U. Although the above-mentioned prior art is conducive to the automatic installation of the voice control program and the plug-and-play of the voice collection device, when the voice collection device collects voice, the collected voice will have a sound leakage effect due to different collection environments. For example, in a noisy environment or when the speaking voice is too loud, sound leakage will occur. Sound leakage will affect the quality of voice collection and make the voice collection effect worse. Therefore, it is necessary to design a voice collection device that prevents sound leakage. Utility Model Content

[0004] In order to solve the technical problem that a voice collection device may produce a sound leakage effect due to problems such as the collection environment, the utility model provides a voice collection device that prevents sound leakage.

[0005] The utility model is implemented by the following technical scheme: a voice collection device for preventing sound leakage, comprising a sound collector body, one side of the sound collector body is provided with a sound leakage prevention component for preventing sound leakage when collecting sound, the bottom of the sound leakage prevention component is provided with an auxiliary component for assisting the sound leakage prevention component to be unfolded to prevent sound leakage, one side of the auxiliary component is provided with a limiting component for limiting the sound leakage prevention component when it is not unfolded, and the sound leakage prevention component comprises a plurality of support rods arranged on one side of the sound collector body and sound insulation cloth fixedly installed between every two adjacent support rods.

[0006] Through the above technical solution, when performing voice collection to prevent sound leakage, the auxiliary component can be slid to allow the anti-sound leakage component to move upward and unfold, thereby limiting the voice collection environment.

[0007] As a further improvement of the above solution, on one side of the two farthest-separated support rods, magnetrons that cooperate with each other are fixedly installed, and a sliding block is rotatably installed at one end of each support rod.

[0008] Through the above technical solution, when the support rods are unfolded and held by the magnetrons, sound leakage prevention for voice collection can be achieved.

[0009] As a further improvement of the above solution, the auxiliary component includes a limiting block sleeved on the sound collector body and a limiting ring fixedly installed on one side of the limiting block and provided with a sliding groove.

[0010] Through the above technical solution, when the support rods are unfolded along the sliding groove of the limiting ring, sound leakage prevention for voice collection can be achieved.

[0011] As a further improvement of the above solution, each sliding block is slidably matched with the limiting ring through a sliding groove.

[0012] Through the above technical solution, the sliding block can drive the support rod to move along the sliding groove.

[0013] As a further improvement of the above solution, the limiting component includes a limiting plate provided on one side of the limiting block and provided with a moving groove, and a moving block slidably arranged inside the moving groove, and one side of the moving block is fixedly installed with the limiting block.

[0014] Through the above technical solution, when multiple support rods are retracted, the limiting plate will prevent the multiple support rods from automatically sliding and unfolding.

[0015] As a further improvement of the above solution, a fixing plate arranged in a "C" shape is fixedly installed at the bottom of the limiting block, a baffle is slidably arranged inside the fixing plate, and one side of the baffle extends to the bottom of the limiting plate.

[0016] Through the above technical solution, the baffle will prevent the limiting plate from moving downward, thereby restricting the multiple support rods.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a sound leakage prevention component, an auxiliary component and a limiting component, when sound leakage prevention protection for voice collection is required, sliding the auxiliary component upward will make the limiting component unable to restrict the sound leakage prevention component. When it moves to the required position, the sound leakage prevention component is unfolded, and the sound leakage prevention component will form a cylinder for sound leakage prevention. Such a setting can not only achieve sound leakage prevention for voice collection, but also remove multiple components when sound leakage prevention is not required, avoiding affecting the use of the sound collector body.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 A voice collection device for preventing sound leakage in the present embodiment includes a sound collector body 1, a sound leakage prevention component for preventing sound leakage when collecting sound is provided on one side of the sound collector body 1, an auxiliary component for assisting the sound leakage prevention component to be unfolded to prevent sound leakage is provided at the bottom of the sound leakage prevention component, and a limiting component for limiting the sound leakage prevention component when it is not unfolded is provided on one side of the auxiliary component. The sound leakage prevention component includes a plurality of support rods 201 arranged on one side of the sound collector body 1 and sound insulation cloth 202 fixedly installed between every two adjacent support rods 201, the sound insulation cloth 202 is made of cloth with a certain sound insulation effect, such as wool cloth and linen cloth, etc., and magnets 8 that cooperate with each other are fixedly installed on one side of the two support rods 201 that are farthest apart, and a sliding block 5 is rotatably installed on one end of each support rod 201. When performing voice collection for preventing sound leakage, the auxiliary component can be slid to allow the sound leakage prevention component to move up and unfold, thereby limiting the voice collection environment.

[0027] Combination Figure 1-Figure 4 The auxiliary component includes a limit block 301 mounted on the sound collector body 1 and a limit ring 302 fixedly installed on one side of the limit block 301 and having a sliding groove. Each sliding block 5 slides with the limit ring 302 through the sliding groove. The sliding block 5 can drive the support rod 201 to move along the sliding groove. The support rod 201 is unfolded along the sliding groove of the limit ring 302, so as to prevent sound leakage during voice collection.

[0028] Combined with Figure 1-Figure 4 , the limiting component includes a limiting plate 401 provided on one side of the limiting block 301 and having a moving groove, and a moving block 402 slidably disposed inside the moving groove. One side of the moving block 402 is fixedly installed with the limiting block 301. A fixing plate 6 arranged in a "C" shape is fixedly installed at the bottom of the limiting block 301. A baffle 7 is slidably disposed inside the fixing plate 6. One side of the baffle 7 extends to the bottom of the limiting plate 401. When the plurality of support rods 201 are retracted, the limiting plate 401 prevents the plurality of support rods 201 from automatically sliding and unfolding.

[0029] The implementation principle of a voice acquisition device for preventing sound leakage in the embodiment of the present application is as follows: When anti-leakage protection for voice acquisition is required, slide the baffle 7 so that the limiting plate 401 can slide on one side of the limiting block 301, and then slide the limiting block 301 upward, which will drive the plurality of support rods 201 to move upward by the limiting ring 302. At the same time, the limiting plate 401 can move downward to act as a handle of the sound collector body 1. After the limiting ring 302 moves upward, the plurality of support rods 201 are slid and unfolded through the sliding block 5. And since the support rod 201 and the sliding block 5 are in rotational cooperation, and the sound insulation cloth 202 is trapezoid-shaped, wider at the top and narrower at the bottom, the support rods 201 can form a conical cylindrical shape after being attracted by the two magnets 8. In this way, when performing voice acquisition, only need to cover or approach the mouth with the conical cylinder to perform anti-leakage protection. When anti-leakage protection is not required, just slide the limiting block 301 and remove it from the sound collector body 1. Such a setting can not only prevent sound leakage during voice acquisition, but also remove the plurality of components when anti-leakage is not required, avoiding affecting the use of the sound collector body 1.

[0030] The above-mentioned implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the scope of protection required by the present utility model.
