Abstract

A receiver is provided in the present invention. The receiver includes: a housing having a hollow inner cavity; a diaphragm mechanism disposed in the hollow inner cavity, partitioning the hollow inner cavity into a first cavity and a second cavity, and including a vibration plate; and an electromagnetic driving mechanism disposed in the hollow inner cavity and including a coil assembly and at least one magnetic field generation member. Each magnetic field generation member is disposed in the first cavity or the second cavity, and the magnetic field generation member is close to a free end of the vibration plate. The coil assembly is disposed in the second cavity and includes a coil and a magnetic core. The coil and the vibration plate are placed in the same direction. The magnetic core is inserted in a hollow inner hole of the coil. A first end of the magnetic core extends out of the hollow inner hole of the coil and is fixed in the second cavity, and a second end of the magnetic core extends out of the hollow inner hole of the coil and serves as a support for the vibration plate. A periphery of the diaphragm mechanism is sealingly connected to an inner wall of the housing. Compared with the prior art, the receiver in the present invention reduces connection between movable parts, thereby simplifying the assembly process and reducing the manufacturing cost.

Abstract

The present invention provides a diaphragm and a receiver using the diaphragm. The diaphragm comprises: a fixing frame, having an inner cavity running through the fixing frame in the thickness direction; a reed, having a hinge end connected to the fixing frame and a vibration end suspended in the fixing frame; and a vibration plate, fixedly connected to the vibration end of the reed, the vibration plate being suspended in the fixing frame, and a predetermined gap being formed between the vibration plate and the fixing frame. Compared with the prior art, the diaphragm in the present invention can improve high frequency response while ensuring high air vibration efficiency, thereby improving the overall condition and performance of a receiver.

Abstract

Provided is a receiver. The receiver comprises: a shell provided with a hollow inner cavity; a diaphragm mechanism arranged in the hollow inner cavity and dividing the hollow inner cavity into a first cavity and a second cavity, the diaphragm mechanism comprising a vibration plate; and an electromagnetic drive mechanism arranged in the hollow inner cavity and comprising a coil assembly and at least one magnetic field generating piece. Each magnetic field generating piece is arranged in the first cavity or the second cavity, and the magnetic field generating piece is close to a free end of the vibration plate. The coil assembly is arranged in the second cavity, and the coil assembly comprises a coil and a magnetic core, wherein the coil and the vibration plate are placed in the same direction; the magnetic core is sleeved in a hollow inner hole of the coil; and a first end of the magnetic core extends out of the hollow inner hole of the coil and is fixed in the second cavity, and a second end of the magnetic core extends out of the hollow inner hole of the coil and serves as a support for the vibration plate. The periphery of the diaphragm mechanism is in sealed connection with an inner wall of the shell. Compared with the prior art, in the present invention, the connection between moving parts is reduced, thereby simplifying an assembly process and reducing manufacturing cost.

Abstract

Provided is a receiver, comprising: a housing having an inner chamber; a diaphragm mechanism disposed within the inner chamber and dividing the inner chamber into a first chamber and a second chamber, the diaphragm mechanism comprising a vibration plate connected to an inner wall of the housing; and an electromagnetic drive mechanism disposed within the inner chamber and comprising a coil assembly and a first magnetic field assembly, wherein the first magnetic field assembly is attached to a side surface of the vibration plate, and the coil assembly is disposed within the second chamber. Compared to the prior art, the present invention has a design in which the first magnetic field assembly, which generates a direct current magnetic field, is attached to one side surface of the vibration plate, such that an alternating current magnetic field generated when a coil is energized interacts with the direct current magnetic field, thereby generating a drive force that vibrates the vibration plate to generate sound without the need for additional drive rods or reeds, accordingly simplifying connections between moving components and the assembly process thereof, reducing manufacturing costs.
