A speaker includes a housing having a receiving space, a speaker unit and a cavity received in the receiving space, sound-absorbing particles filled in the filling cavity, a filling hole opened in the housing and communicating with the filling cavity for filling the sound-absorbing particles into the filling cavity, a hole cover covering the filling hole and a resilient member filled in the filling hole. The resilient member can deform in the height direction of the filling hole, and the resilient member is sandwiched in a compressed state between the hole cover and the sound-absorbing particles. Compared with the related art, the sound-absorbing particles of the speaker disclosed by the present disclosure are not easily damaged.

The present application relates to the technical field of architectural engineering. Disclosed are a slab joint leakage-proof structure of a prefabricated roof panel, a prefabricated roof panel and a prefabricated roof panel system. The slab joint leakage-proof structure comprises a first leakage-proof layer. The first leakage-proof layer comprises two flexible structures which abut against each other and are arranged at the joint of a main rib on the long side of the roof panel and a main rib on the long side of an adjacent roof panel. Either of the flexible structures comprises a main body portion sealably attached to the main rib, and at least one protruding portion which is fixedly disposed on the main body portion, protrudes and extends into the joint, and can tightly abut against the other flexible structure. The protruding portions of the two flexible structures can enclose an air cavity layer sealably isolated from the outside. The air pressure of the air cavity layer is higher than that of the outside for preventing liquid on the bottom end of the joint from permeating into the air cavity layer and entering a room. The slab joint leakage-proof structure has good waterproof performance. The flexible structures are sealably connected to the main ribs, and are not easy to fall off, and the problem that the waterproof performance is poor due to the fact that a mortar is easy to fall off in an existing waterproof mode of filling the mortar is solved.

The present invention provides a speaker, including: a housing body having an accommodation cavity with a first chamber and a second chamber; a first side wall and a second side wall enclosing the first chamber; a third side wall and a fourth side wall enclosing the second chamber; and a speaker unit including a connection part located in the first chamber and a sounding component connecting to the connection part. A distance between the first side wall and the second side wall is smaller than a distance between the third side wall and the fourth side wall. The speaker enables the connection part to be connected to the side wall of the housing body without the end of the connection part needing to exceed the end of the sounding component, which reduces the volume of the housing body and facilitates the miniaturized design of the speaker.

A speaker includes a frame with a leakage hole, a magnetic circuit system and a vibration system received in the frame and a mesh covering the leakage hole. The vibration system comprises a diaphragm and a coil. The magnetic circuit system comprises a lower clamp and a magnet assembly stacked on the lower clamp. The mesh is integrally injection-molded with the frame, and comprises a central portion opposite to the leakage hole and a fixed portion located around the central portion and fixed with the frame. The fixed portion comprises an embedded portion embedded in the frame. The frame comprises a cover portion covering the embedded portion. The cover portion is provided with a recessed portion recessed from the surface of the cover portion away from the embedded portion toward the embedded portion until in contact with the embedded portion.
