Abstract

The invention relates to an in-ear receiver, which comprises a stainless steel support, a voice coil, a cylindrical magnet, a diaphragm, a PC board and a sheath, wherein the cylindrical magnet is arranged in the center of the cavity inside the stainless steel support; the inner cavity of the stainless steel support has a diameter of 16 to 20mm; the cylindrical magnet has a diameter of 5 to 10mm; the voice coil is formed by winding and is fixed below the diaphragm; the diaphragm is arranged above the cylindrical magnet; the top end of the stainless steel support is provided with a step, and the lower end of the sheath is attached to the step of the stainless steel support; the PC board is fixed on the stainless steel support inside the sheath and is in winding connection with the voice coil; and a damping plate is arranged below the inner part of the support. The size of the in-ear receiver is further reduced, magnetic leakage can be reduced, and sound production effects are improved.

Description

technical field [0001] The invention specifically relates to an in-ear receiver. Background technique [0002] The receiver is an electroacoustic transducer that converts electrical signals into corresponding acoustic signals in speech communication. In the prior art receiver, the voice coil is set in the gap formed by the external magnetic ring and the internal T-shaped iron, and it must be ensured that the voice coil is placed in the center of the magnetic gap, and it cannot touch the magnet or the T-shaped iron during vibration. There are restrictions on the size of the voice coil. However, the sensitivity of the receiver depends on the wire length of the voice coil, which in turn requires the internal volume of the receiver to meet certain requirements. This increases the design difficulty of the receiver, and the miniaturization of the receiver is limited. Contents of the invention [0003] The object of the present invention is to provide an in-ear receiver aimed ...
