The utility model discloses a kind of magnetic shaft structures that can sound, including base, the upper cover being set on base, the guide core being movably set between base and upper cover, and the elastic member being sleeved between base and guide core, further including the magnet being sleeved on the bottom of the guide core, the lower end of guide core is formed with magnetic installation groove, the middle part of magnetic installation groove is formed with the sound column extending towards base direction;Magnet is overall circular ring column shape, it is embedded in the magnetic installation groove, wherein hollow part is sleeved on the periphery of sound column;The lower end of sound column penetrates through magnet lower end surface and continues to extend downward, and its downward extending portion is impacted base to sound under the action of external force.The utility model provides a kind of magnetic shaft structures that can sound, guide core is impacted on base when being pressed and moved downward, magnet is sleeved on guide core, so as to realize good sound effect in the case where magnet is not damaged and the transmission accuracy is guaranteed, improve the use experience of user.

The utility model relates to diaphragm technical field, concretely is a kind of novel elastic composite flat diaphragm, the flat diaphragm includes support and diaphragm component, hollow hole is opened in the support, the diaphragm component is fixed on support, and hollow hole is completely shielded, the diaphragm component includes elastic membrane layer and the metal layer being arranged on the upper and lower ends of elastic membrane layer, electrically conductive coil is arranged at hollow hole on the metal layer, the both ends of electrically conductive coil are all provided with conducting point, and the conducting point and electrically conductive coil are electrically connected, and the protective layer is provided on the end face of electrically conductive coil away from metal layer. The utility model has simple structure, reasonable in design, diaphragm sound production effect is good, service life is long, and electrically conductive coil resistance adjustable, satisfy the use demand of different products, it is worth promoting and using.

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 application provides a sound generating module mounting structure and an air conditioner with the same, the sound generating module mounting structure comprises a front shell, a first covering part and a detachable top cover plate are arranged on the front shell, the first covering part and the top cover plate form a top part of the front shell, a sound generating hole is arranged on the top cover plate, a sound generating module is arranged on the lower side of the top cover plate, the sound generating module is arranged correspondingly with the sound generating hole and is used for generating sound through the sound generating hole. Through the arrangement of the top cover plate and the sound generating module below the top cover plate, the indoor unit of the air conditioner generates sound through the top part, on the one hand, the appearance of the cabinet type indoor unit is not affected, on the other hand, the indoor unit is not affected by being placed in a corner position, through the arrangement of the film, the electric control box obtains good heat dissipation performance in the case of shielding electromagnetic interference. The application has the advantages of simple structure, simple and convenient assembly and improved precision of voice instruction control of users.
