Description
Technical Field
[0001] The utility model relates to the technical field of receivers, in particular to a receiver device. Background Art
[0002] A receiver usually refers to an electronic device that can receive electrical signals and convert them into sound signals so that people can hear the sounds. Receivers are common components in phones, headphones, speakers and other audio devices.
[0003] The main function of a receiver is to convert electrical signals into sound waves. Its working principle is usually based on electromagnetic induction or electrostatic effect. The following are common receivers: Dynamic receiver: This is the most common type. It uses a coil and a permanent magnet. When current passes through the coil, the coil moves in the magnetic field, pushing the diaphragm connected to it to generate sound waves; Electrostatic receiver: This receiver uses an electrostatic field to drive the diaphragm. Electrostatic receivers are usually able to provide more delicate audio quality; Magnetostrictive receiver: This receiver uses the property of magnetostrictive materials to deform in a magnetic field to produce sound; Flat receiver: This receiver uses a planar coil and a magnetic field to drive the diaphragm, and is usually used in high-end headphones.
[0004] However, a dynamic receiver is installed in the handset of a fixed telephone on the market. The dynamic receiver is circular in shape and connected by two connecting wires extending from the handset. After the dynamic receiver is connected to the connecting wires, it is directly placed in the space reserved for the receiver in the handset, and then the screw cap is tightened on the outside of the receiver to fix it. However, the receiver is in a movable state in the handset. After the receiver is used for a long time or is impacted by external force, it is very easy to shake in the handset, causing the handset to change the sound path due to the displacement of the diaphragm shell and the voice coil shell, causing sound distortion and affecting the sound quality. In addition, the position change of the voice coil shell and the diaphragm shell may affect the sound output efficiency, resulting in a decrease or increase in the volume. In view of this, a receiver device is provided to overcome the above defects. Utility Model Content

[0007] As a further description of the above technical solution: the interior of the hollow tube is slidably connected to the outer side of the sliding rod, and the end of the top plate close to the voice coil shell is in contact with the surface of the voice coil shell.

[0010] As a further description of the above technical solution: the number of rubber sheets matches the number of top plates, and the overall curvature of the rubber sheets is arranged to match the outer surface of the top plates. The thickness of the rubber sheets is two millimeters, which can effectively increase the friction between the inner edge of the earpiece and the top plate, and improve the stability of the top plate extending outward and contacting the inner edge of the earpiece.

[0012] As a further description of the above technical solution: the first connecting wire and the second connecting wire are both fixed to the top of the rotating ring by winding around the threaded rod, the first connecting wire is wound around the upper position of the outside of the threaded rod, and the second connecting wire is wound around the lower position of the outside of the threaded rod. The length of the first connecting wire and the second connecting wire in the earpiece can be reduced by winding around the outside of the threaded rod.
[0013] As a further description of the above technical solution: the pitch of the internal thread on the inner side of the rotating ring matches the pitch of the external side of the threaded rod, the cross-sectional diameter of the rotating ring matches the cross-sectional diameter of the fixing seat, and the edge thickness of the rubber ring is half of the edge thickness of the rotating ring. The threaded rod and the internal thread on the inner side of the rotating ring can be spirally connected with each other, so that the rubber ring on the top of the rotating ring can contact and squeeze the surface of the first connecting line and the second connecting line. The rubber ring is made of a relatively soft material, which can prevent the first connecting line and the second connecting line from being squeezed by the hard rotating ring for a long time and being damaged.
[0014] The utility model has the following beneficial effects:
[0015] The receiver device designed by the utility model is designed to cooperate with the compression spring and the top plate, so that after the voice coil shell and the diaphragm shell are installed and placed inside the telephone receiver, the top plate is squeezed by the compression spring and expands outward, so that the voice coil shell and the diaphragm shell are stuck in the center position inside the receiver, which can effectively prevent the voice coil shell and the diaphragm shell from being offset under the action of external force after the receiver is used for a long time, resulting in the receiver changing the sound path due to the displacement of the diaphragm shell and the voice coil shell, causing sound distortion and affecting the sound quality, and the position change of the voice coil shell and the diaphragm shell may affect the output efficiency of the sound, resulting in the occurrence of situations such as volume reduction or increase, etc., thereby improving the structural stability of the receiver in the receiver to a certain extent.
