Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of multifunctional sound calibrators, in particular to a multifunctional sound calibrator. Background Art
[0002] The multifunctional acoustic calibrator can generate sound pressure levels at multiple frequencies and can perform acoustic calibration on test microphones, sound level meters, and other acoustic measuring instruments over the entire audio frequency range. It can also obtain acoustic and electrical frequency weightings and frequency responses. It can also verify and calibrate time weighting, level linearity, tone burst response, and repetitive tone burst response. It is a widely used laboratory and on-site acoustic verification and calibration device.
[0003] Most of the existing multifunctional sound calibrators connect the multifunctional sound calibrators to the coupling cavity through connecting cables. However, the connecting cables are easily tangled during storage and carrying. When the multifunctional sound calibrator needs to be used, it takes time to untangle the tangled connecting cables, which reduces work efficiency. This inconvenience is especially prominent in scenarios such as outdoors where calibration work needs to be performed quickly. At the same time, when using the existing multifunctional sound calibrators, most of them are directly placed on the hands for operation. When the hands become sore, it may lead to insufficient grip, which makes the multifunctional sound calibrator at risk of falling.
[0004] Therefore, we propose a multifunctional sound calibrator to solve the above problems. Utility Model Content
[0005] 1. Technical problems to be solved by the utility model:
[0006] The purpose of the present utility model is to provide a multifunctional sound calibrator to solve the problems in the current market raised by the above background technology.

[0009] An elastic clip is installed on the side of the multifunctional sound calibrator body, and the elastic clip is used to fix the coupling cavity. An elastic band is provided on the rear side of the multifunctional sound calibrator body, and the upper and lower ends of the elastic band are fixedly connected to the multifunctional sound calibrator body.
[0010] Furthermore, the storage container includes a shell, a rotating drum is rotatably installed inside the shell, and the left end of the rotating drum is connected to a rotating plate on the outside of the shell, and a torsion spring is installed between the rotating drum and the shell.
[0011] Through the above technical solution, when the rotating drum is not subjected to external force, it can rotate in the opposite direction and reset under the action of the torsion spring.
[0012] Furthermore, the ends of the connecting line 1 and the connecting line 2 close to the receptacle are fixed on the rotating drum, and the middle parts of the connecting line 1 and the connecting line 2 are wound in the same direction on the outside of the rotating drum.
[0013] Through the above technical solution, after the rotating drum rotates, the connecting line 1 and the connecting line 2 can be wound around the rotating drum.
[0014] Furthermore, the clamping part includes a fixing frame fixed to the outside of the shell, the internal bearing of the fixing frame is installed with a threaded rod, and the threaded rod is fixed with a rotating block on the outside of the fixing frame, and a movable block is sleeved on the outside of the right end of the threaded rod, and a pressure plate is fixed to the right end of the movable block.
[0015] Through the above technical solution, the pressing plate and the movable block can be displaced synchronously.
[0016] Furthermore, the side of the movable block is fitted with the inner wall of the fixing frame, and the movable block and the threaded rod are threadedly connected.
[0017] Through the above technical solution, when the threaded rod rotates, the pressure plate and the movable block can be driven to move.
[0018] Furthermore, a rubber pad is installed on the side of the pressure plate close to the rotating plate.
[0019] The above technical solution can improve the compacting effect.
[0020] 3.Beneficial effects:
[0021] Compared with the prior art, the present invention adopts the technical solution provided by the present invention. The multifunctional sound calibrator can store the coupling cavity and the connecting wire through the cooperation of the storage container and the elastic clip, so as to facilitate carrying. At the same time, the elastic band can prevent the device from falling due to insufficient grip strength. The specific contents are as follows:
[0022] When storing and carrying, the rotating block drives the threaded rod to rotate synchronously. The movable block, which is threadedly sleeved on the outside of the threaded rod, drives the pressure plate away from the rotating plate by the contact between the movable block and the fixed frame. Then, under the elastic action of the torsion spring, the rotating drum is driven to rotate. During the rotation of the rotating drum, the connecting wires 1 and 2 are driven to rewind into the interior of the shell for storage. The coupling cavity is fixed to the side of the multifunctional sound calibrator body by an elastic clip to facilitate storage and carrying.
[0023] When in use, take out the coupling cavity, then pull out connecting wires 1 and 2 from the inside of the shell, and then rotate the rotating block in the opposite direction. Following the above working principle, drive the pressure plate close to the rotating plate, press the rotating plate tightly to prevent the rotating cylinder from rotating in the opposite direction, and then place your palm between the elastic band and the multifunctional sound calibrator body. The multifunctional sound calibrator body and the coupling cavity can be used for calibration operations. Under the action of the elastic band, it can prevent the device from falling due to insufficient grip strength of the hand. BRIEF DESCRIPTION OF THE DRAWINGS
