[0002] Audio devices usually need to be equipped with a volume adjustment structure to adjust the sound output. Existing volume adjustment structures mainly include mechanical volume adjustment structures and electronic volume adjustment structures. Among them, the mechanical volume adjustment structure means that the user changes the gain of the audio signal through physical operation to adjust the volume.

[0003] The existing mechanical volume adjustment structure may include a knob, which includes a knob shaft. The knob shaft is a key component for transmitting rotational force. A mechanical movement is arranged on one side of the knob shaft. The mechanical movement includes contacts and a resistor element. When the user rotates the knob, the knob shaft rotates and the contacts move at the same time. The contacts move to change the resistance value. The change in resistance value causes the current in the circuit to change, thereby changing the voltage signal output by the audio device, and the volume is adjusted.

[0004] However, the existing volume adjustment structure has a relatively single function. When the audio device needs to perform multi-functional operations, multiple switch components need to be provided, and the multiple switch components tend to occupy more space. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the utility model provides a multifunctional volume adjustment control structure, in which the volume is adjusted by rotating a knob. At the same time, by pressing the knob, the knob shaft presses the switch key by rotating a pressing piece.

The contact end 31 and the pressing end 32 are both located on the rotating pressing block 34. The rotating pressing block 34 is located on the side of the sleeve 35 away from the knob 2. When the knob 2 is pressed, the knob 2 pushes the contact end 31 toward the switch key 12. The contact end 31 is subjected to a horizontal thrust. Under the action of the lever principle, the shaft 33 drives the sleeve 35 and the pressing end 32 to rotate. The shaft 33 rotates in the concave hole 131. The pressing end 32 presses down the switch key 12, and the switch key 12 is in an open state. The rotating pressing member 3 has a simple structure. The knob 2 is convenient to operate by rotating the pressing member 3 to control the opening and closing of the switch key 12.

The end of the clamping column 46 away from the connection with the second shell 43 passes through the mounting plate 1 and is clamped into the clamping sleeve 45. The clamping column 46 and the clamping sleeve 45 are clamped together to realize the detachable assembly of the first shell 42 and the second shell 43.

[0049] In a preferred embodiment, the mounting plate 1 is detachably connected to the second shell 43, a threaded sleeve 431 is installed on the inner wall of the second shell 43, a second reinforcing rib is provided on the outer wall of the threaded sleeve 431, and the mounting plate 1 and the threaded sleeve 431 are assembled by screws, which is conducive to the convenient disassembly and assembly of the mounting plate 1.

When the first shell 42 and the second shell 43 are covered, the first fitting groove 421 and the second fitting groove 432 are staggered so that the first shell 42 and the second shell 43 fit each other, thereby improving the sealing performance of the housing 4 after assembly. Furthermore, the first shell 42 is provided with a plurality of sealing strips 47 at the edge of the opening, and the plurality of sealing strips 47 are distributed at intervals along the edge of the opening of the first shell 42, and the sealing strips 47 can further improve the sealing performance of the first shell 42 and the second shell 43 after covering.

[0051] Reference Figure 2 and Figure 7In a preferred embodiment, a bone position 441 is installed on the inner wall of the first housing 42. The bone position 441 is arranged opposite to the knob 2. Specifically, the bone position 441 is a cross-shaped protrusion. The bone position 441 includes a limiting portion 4411. A guiding inclined surface is arranged on the side of the limiting portion 4411 close to the knob 2. The guiding inclined surface is inclined from the side of the limiting portion 4411 close to the knob 2 toward the inner wall of the first housing 42. A limiting ring 442 is arranged on the side of the knob 2 close to the bone position 441. The limiting ring 442 is a circular ring and is sleeved on the outside of the bone position 441.
