Description

Vacuum testing device for detecting inside of loudspeaker cavity of loudspeaker Technical Field The utility model relates to the technical field of loudspeaker detection, in particular to a vacuum testing device for detecting the inside of a loudspeaker cavity of a loudspeaker. Background In the current consumer market of loudspeaker loudspeakers, some products are located in outdoor use scenes, and many uncertain factors exist in outdoor scenes, which also include severe environments, and in this case, the loudspeaker loudspeakers have strict requirements on water resistance and tightness. Some conventional horn workflow methods may lack a scientific and effective method of detection, which designers typically make decisions through structural analysis and past accumulated experience. The judging mode lacks scientificity and accuracy, lacks effective persuasion for wide consumers, and cannot accurately judge the waterproof sealing effect of the loudspeaker. Under the condition of lacking effective instrument detection equipment, after the speaker that does not strictly detect flows into the market, there is the risk that the water stain invaded, once the water stain invaded, very easily leads to the speaker to burn out, influences the normal use of product. Moreover, the judgment is performed in a subjective assumption manner, so that not only is the effective persuasion lacked, but also a plurality of uncertainties exist, which can lead to market complaints of a large number of produced speakers due to quality problems, and therefore, a device capable of scientifically and accurately detecting the tightness inside the speaker cavity of the speaker is needed. Disclosure of utility model The utility model mainly aims to provide a vacuum testing device for detecting the inside of a loudspeaker cavity of a loudspeaker, which is used for solving the technical problems. The vacuum testing device for detecting the interior of the loudspeaker cavity of the loudspeaker comprises a base and the loudspeaker detachably mounted on the base, wherein a frame is arranged on the base, a movable adjusting mechanism is arranged on the frame, a fixed head is arranged at the output end of the movable adjusting mechanism and is abutted to the rear end of the loudspeaker, and the vacuum testing device further comprises a vacuum tester, and an air pipe is arranged at the output end of the vacuum tester and is detachably connected with the fixed head. On the basis of the scheme and as a preferable scheme of the scheme, the movable adjusting mechanism comprises a transverse plate detachably arranged at the top of the frame, a first fixing groove is formed in the transverse plate, a mounting plate is detachably arranged on the first fixing groove, a fixing seat is arranged on the mounting plate, a pressing handle is hinged to the top of the fixing seat, a sleeve is further arranged on the fixing seat, a pressing rod is slidably arranged in the sleeve, a connecting block is arranged at the top of the pressing rod, the pressing handle is hinged to the connecting block, and the bottom of the pressing rod is detachably connected with the fixing head.
