Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a bone conduction testing device and a soundproof box. Background Technology

[0002] Bone conduction microphones, also known as vibration microphones, work by generating mechanical vibrations with frequencies and amplitudes that match sound signals. These vibrations move through the body's tissues and bones, stimulating the auditory nerve in the cochlea and enabling the listener to hear. These speakers are sometimes referred to as bone conduction headphones.

[0003] Common Bluetooth glasses typically integrate bone conduction speakers. However, due to the unique shape of the glasses and the fact that bone conduction microphones are usually located on the bridge of the nose in the middle of the glasses, traditional bone conduction testing equipment is often incompatible with them.

[0041] Reference Figures 1-4 The first aspect of this utility model provides a bone conduction testing device, comprising:

[0042] Base 100;

[0043] The clamping mechanism 200 includes a hollow bracket 210 and a clamping sleeve 220. The hollow bracket 210 is disposed on the base 100, and the clamping sleeve 220 is used to fix the object to be measured on the hollow bracket 210.

[0044] The vibrator 300 is located on the base 100, and the hollow bracket 210 is placed obliquely above the base 100. The vibrator 300 is used to pass through the middle of the hollow bracket 210 and come into contact with the object to be tested.

[0045] According to the embodiments of this utility model, by such a setting, at least the following effects can be achieved: the clamping mechanism 200 can mount the object to be tested on the hollow bracket 210 through the cooperation of the hollow bracket 210 and the clamping sleeve 220. The hollow bracket 210 is hollow in the middle, so that the lower part of the object to be tested is exposed on the vibrator 300. The vibrator 300 passes through the middle of the hollow bracket 210 and abuts against the nose of the object to be tested, generating a vibration effect on the object to be tested. After the object to be tested transmits the test results to the controller, the test results are obtained. The hollow bracket 210 is placed obliquely on the base 100, so that the object to be tested can also be placed obliquely above the vibrator 300, so that the vibrator 300 can abut against the nose of the object to be tested.

[0046] Hollowed-out refers to a hollowed-out object that appears as a complete pattern on the outside but is empty inside.

[0047] In some embodiments, the clamping sleeve 220 is rotatably disposed on the hollow bracket 210. The clamping mechanism 200 can be opened or closed by means of the clamping sleeve 220. When opened, the object to be tested can be placed in the hollow bracket 210. When closed, the object to be tested can be fixed in the hollow bracket 210.

[0048] Furthermore, the clamping mechanism 200 also includes a torsion spring 230. The torsion spring 230 has a connecting shaft at its center between the clamping sleeve 220 and the hollow support 210. Both ends of the torsion spring 230 are connected to the clamping sleeve 220 and the hollow support 210, respectively. The torsion spring 230 drives the clamping sleeve 220 and the hollow support 210 to remain in a normally closed state, allowing the object to be tested to be securely mounted on the hollow steel support. When the object to be tested needs to be replaced, the clamping sleeve 220 is opened; releasing it causes the clamping sleeve 220 to automatically close, facilitating use.

[0049] In some embodiments, a locking mechanism 400 is further included, which is used to fix the clamping sleeve 220 to the hollow bracket 210. The clamping sleeve 220 is fixed to the hollow bracket 210 by the locking mechanism 400.

[0050] In some embodiments, the locking mechanism 400 includes:

[0051] The buckle is rotatably mounted on the hollow bracket 210 or the clamping sleeve 220;

[0052] An elastic element is provided in the hollow bracket 210 or the clamping sleeve 220. The buckle is driven by the elastic force to move towards the middle of the hollow bracket 210.

[0053] In this configuration, the clip 220 is secured to the hollow bracket 210 by snapping together. By pressing the clip structure, the clip can be moved away from the hollow bracket 210, causing the clip 220 to release the bracket. The clip is then driven by elastic force to move towards the center of the hollow bracket 210, so that the clip engages with the clip 220.

[0054] In some embodiments, an adjustment mechanism 500 is also included, which is used to drive the clamping mechanism 200 to move. The adjustment mechanism 500 can adjust the position of the hollow bracket 210 in the up-down, left-right, or front-back directions, so that the output end of the vibrator 300 can be connected to the object under test.

[0055] Furthermore, the adjustment mechanism 500 includes multiple sliding brackets and multiple adjusting nuts. By adjusting the position of the adjusting nuts, the corresponding adjusting brackets are moved, thereby adjusting the position of the brackets so that the output end of the vibrator 300 can be connected to the object under test.

[0056] In some embodiments, the vibrator 300 is located below the clamping mechanism 200, and the vibrator 300 is provided with an extension head 310 that passes through the hollow bracket 210. The extension head 310 can increase the distance of the output end of the vibrator 300, so that the vibration effect of the vibrator 300 can be transmitted to the object under test.

[0057] In some embodiments, the clamping sleeve 220 is provided with a plurality of pressure blocks 221, which are used to press down the test object.

[0058] Furthermore, the pressure block 221 is made of an elastic material. The elastic pressure block 221 is equivalent to the elasticity of human skin, which is suitable for the testing environment of the test object and plays a shock-absorbing role, which can reduce the damage to the test object.

[0059] In some embodiments, an adjusting member is also included, which drives the pressure block 221 to approach the hollow support 210. The adjusting member can adjust the distance between the pressure block 221 and the object to be tested, adjust the pressure between the pressure block 221 and the object to be tested, and prevent the pressure block 221 from damaging the object to be tested.

[0060] In some embodiments, the adjusting member is threadedly connected to the perforated bracket 210. The adjusting member can adjust the distance between the pressure block 221 and the object to be tested, thereby adjusting the pressure between the pressure block 221 and the object to be tested and preventing the pressure block 221 from damaging the object to be tested.

[0061] In some embodiments, the perforated bracket 210 is provided with a supporting crossbeam, and the supporting crossbeam is provided with a slot. The slot of the supporting crossbeam is used to abut against the middle of the object to be tested, which can further fix the position of the object to be tested.

[0062] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0063] Although some embodiments of the present utility model have been shown and described in this specification, the present utility model should not be limited to the above embodiments. As long as they achieve the technical effects of the present utility model by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles disclosed in the present utility model, without departing from the principles and purpose of the present utility model, should be included within the scope of protection disclosed in the present utility model and should be considered to fall within the protection scope of the present utility model.
