This utility model discloses a dual-function over-ear headphone, relating to the field of headphones. It includes a headband, with an earphone body connected to the bottom of the headband. A sponge pad is connected to the side of the earphone body, and a microphone is installed on the side of the earphone body away from the sponge pad. A mounting groove is formed on the side of the mounting groove, and a miniature air pump is installed inside the mounting groove. The output end of the miniature air pump is connected to a connecting pipe, which passes through and connects to the side of the airbag ring. A compression ball slides inside the telescopic groove. In this dual-function over-ear headphone, the airbag ring can expand inside the mounting groove after being supplied with gas. When the airbag ring expands, it can compress the side walls of the waterproof membrane and waterproof mesh fabric, improving the sealing effect of the earphone body. When the sponge pad is pulled, it can cause the sliding block to slide out of the L-shaped groove, and at the same time, the fixing block will also slide out of the surface of the fixing ring, allowing the sponge pad and the earphone body to be separated and disassembled, improving the convenience of using the headphones.

The utility model discloses a mouse button pre -press structure, including mouse main part, button subassembly, micro -switch and plastic framework, and the button column is established between the button subassembly bottom abutment structure and micro -switch, the steel wire clamping spring is installed in the inside of the reverse pull arm of plastic framework front end, and the abutment structure is connected with the end of clamping spring, and the silica gel cover of button column is wrapped wear -resisting piece, and the silica gel edge first buffering when contacting micro -switch, and the pre -pressure is exerted to button subassembly through the reverse pull arm of clamping spring, and the balance button tension is made, and the down pressure is consistent with switch feedback force, and when rebounding, the button column is limited to hit the framework, and the hand feeling and noise are improved, and the no -loop fool -proof design of two end hooks vertical intersection is adopted to clamping during assembly, and the installation difficulty is reduced, and the structure is through the pre -pressure spring and silica gel buffer design, and the button hand feeling and assembly efficiency are promoted, and the problem that the existing torsion ring structure buffer is poor and assembly is complicated is solved.

The application provides a kind of loudspeaker sound optimization system and method, belongs to loudspeaker technical field, containing loudspeaker support, the loudspeaker support is equipped with loudspeaker body, the outside of the loudspeaker support is fixedly connected with connecting outer ring;The outer circumferential surface of the connecting outer ring is fixedly connected with assembly outer ring, and the assembly outer ring is reserved with mounting hole;The upper and lower two side rods on the loudspeaker support are equipped with anti-oscillation module;The other end of the anti-oscillation module is equipped with assembly rod.The application solves the problem that the existing loudspeaker lacks structure to reduce oscillation, and the loudspeaker will produce oscillation during work, which will cause the components to touch each other, and noise will be generated when touching, which will cause the sound quality played by the loudspeaker to deteriorate during work, and the oscillation will also cause the connection between parts to be loose or even detached.

The application provides a split type sound box, which comprises a first sound box body and a second sound box body buckled together, the first sound box body is provided with a clamping groove structure, the second sound box body is provided with a clamping body structure matched with the clamping groove structure, the first sound box body comprises a first shell and a first loudspeaker assembly installed in the first shell, the first shell is further provided with a first cover plate assembly matched with the first shell and used for fixing the first loudspeaker assembly, and the first cover plate assembly is provided with a first panel assembly. The split type sound box has the advantages of good sound quality, flexible use mode, effective improvement of the atmosphere of the use environment and the like, and greatly improves the use experience of customers.

The embodiment of the application discloses a human voice recognition and enhancement method and device for a voice device and a storage medium, relates to the field of communication technology, and can be applied to a scene in which sound of a intercom in a mask needs to be amplified and sound enhanced in emergency rescue. The application comprises the following steps: performing echo cancellation on collected sound signals by an NLMS algorithm, wherein the collected sound signals comprise environmental noise and voice signals; performing spectrum analysis on the sound processed in step 1, and extracting sound signals conforming to human voice characteristics; performing enhancement processing on the sound signals conforming to human voice characteristics by an IIR; and sending the sound signals processed by the enhancement processing to a intercom module.
