Description

Technical Field

[0001] This utility model relates to the field of broadcasting and television technology, and in particular to an intelligent broadcasting and television volume adjustment device. Background Technology

[0002] Broadcast and television volume control equipment is the core device for regulating the audio output of broadcast and television. It achieves volume control by adjusting the audio signal gain, which can effectively avoid sudden volume changes when switching programs or inserting advertisements. With its wide adjustment range, high precision, and excellent signal-to-noise ratio, it is widely used in home theaters, public broadcasting and other scenarios. Among them, the hardware knob-type adjustment structure has become the mainstream form in the market due to its intuitive operation and direct response.

[0003] However, this smart broadcast television volume control device has the following drawbacks:

[0004] (1) At present, most volume control knobs are directly exposed. Dust and moisture in the environment can easily penetrate the twisting and mating parts between the knob and the device body. Long-term accumulation will cause the knob to jam and have poor contact. In severe cases, the knob will completely fail, which will not only greatly shorten the service life of the device and increase maintenance costs, but also affect the normal user experience due to frequent failures.

[0005] (2) When the connection terminal at the rear end of the equipment is connected to the wire, there is no effective fixed limit structure. When the wire is pulled by external force or the equipment is moved slightly, the wire is easily detached from the connection terminal. This will not only cause the audio signal transmission to be interrupted, but may also cause safety hazards such as poor contact and short circuit due to the wire falling off. Especially in high-frequency use scenarios such as public broadcasting, it is easy to cause the broadcasting system to be paralyzed and affect normal use. Utility Model Content

The spring 403 is compressed, and at this time the first elastic clip 405 is engaged in the limit hole 406 of the fixing plate 7, thereby fixing and locking the protective box 404 to prevent accidental sliding. This allows the knob to be exposed for operation. In normal state, the protective box 404 is kept closed under the elastic thrust of the spring 403 on the outer periphery of the limit rod 402, completely covering all volume adjustment knobs 2 and preventing environmental impurities from contacting the knob turning parts, thereby improving the service life of the equipment.

[0037] The second step: When installing the wire, first insert the end 6 into the ring buckle 501, then put the ring buckle 501 on the outer periphery of the wire port 3, and align the second elastic clip 504 on the inner side of the ring buckle 501 with the slot 502 of the fixing ring 503 and lock it in place. At this time, the ring buckle 501 is tightly fitted with the outer wall of the wire port 3, forming an axial pressing force on the end 6. Even if the wire is pulled by external force or the equipment moves slightly, the end 6 can be prevented from loosening. When it is necessary to disassemble the wire, press the second elastic clip 504 to disengage it from the slot 502, and the ring buckle 501 can be removed and the end 6 can be pulled out. The operation is convenient and does not damage the components.
