  • Patent number: 10321240
    Abstract: A receiver comprises a peripheral housing, and a magnet circuit system and a vibrating system. The vibrating system comprises a vibrating diaphragm and a voice coil. The periphery housing comprises a first and second housing matched with each other, which are provided with electrical connection structures conductive with each other. A sidewall of the first housing is provided with a first elastic piece including one end welded with a spring electrically connected to an external circuit and another end exposed at the outer side of the sidewall of the first housing. A sidewall of the second housing is provided with a second elastic piece including one end electrically connected with a lead wire of the voice coil and another end exposed at the outer side of the sidewall of the second housing and welded and fixed with a portion of the first elastic piece exposed to the outer side.

  • Patent number: 10284936
    Abstract: Disclosed is a receiver comprises an external housing, the external housing comprises a first housing, a second housing and a third housing adapted with each other from top to bottom, a vibration system is accommodated in a cavity formed by the external housing and comprises a vibration diaphragm dividing the receiver into a front sound cavity and a rear sound cavity, the third housing is injection-molded and provided with a sound outlet hole of the rear sound cavity which is in communication with outside environment. The third housing is coupled with a mesh fabric at a position corresponding to the sound outlet hole by injection-molding, and the mesh fabric isolates the rear sound cavity from the outside environment. The receiver can effectively prevent performance degradation of a product caused by impurities of the outside environment falling into the rear cavity, thereby providing a function of product protection.

  • Patent number: 10129619
    Abstract: The present invention discloses a receiver comprising an outer housing that consists of a first housing, a second housing and a third housing fitting to each other from top to bottom. The third housing is an integral structure, and includes a magnetic conductive piece and a plastic piece integrally injection-molded therewith. The magnetic conductive piece is bonded and fixed with a magnet and a washer. The magnetic conductive piece, the magnet and the washer together form a magnetic circuit system of the receiver, and the third housing is fixed with the second housing by ultrasonic welding through the plastic piece. The receiver of the present invention can realize one-step assembly of the rear cavity housing of the product, simplify the production process of the product, save the production time, and further reduce the production cost of the product.
