Earphone structure with elliptical loudspeaker

Abstract

The utility model discloses an earphone structure with an elliptical horn, which comprises an earphone shell A. The earphone shell A is internally provided with a wire arrangement protection tube which is used for arranging a wire harness and is of an L-shaped structure through a positioning plate, and the external center position of the wire arrangement protection tube is provided with a swinging handle part which enables the earphone wire harness to swing and move along with the swinging handle part. When a person wears the earphone to move, the generated wind resistance blows the swing handle part to swing in a small range, the swing handle part swings in the movable hole groove through the swing fixing pipe, the swing fixing pipe swings in the annular limiting groove through the limiting ring piece, and therefore the swing handle part swings stably in a small range under the wind resistance condition; the problem that the earphone shakes and falls off in the ear canal due to the fact that the swing handle part is blown by wind resistance is solved, so that the phenomenon that the earphone shakes in the ear canal due to the wind resistance can be reduced, and the wearing stability is further kept when the earphone moves in the ear canal.

Description

TECHNICAL FIELD

[0001] The utility model belongs to earphone structure technical field, concretely relates to an earphone structure of oval loudspeaker. BACKGROUND

[0002] The most common earphone is a moving coil earphone, which makes a voice coil vibrate through the action of a magnetic field, drives a diaphragm to vibrate, and forms sound. The shell of the existing earphone is mostly circular or oval, and there are also many shells designed into special shapes to meet the needs of ergonomics and aesthetics; but the loudspeaker in the shell and the diaphragm on the loudspeaker still use the traditional circular diaphragm. For the oval shell earphone with the highest occurrence rate, the circular loudspeaker in the oval shell does not make full use of the space in the shell cavity, resulting in structural waste.

[0003] Therefore, the earphone with an oval loudspeaker with publication number "CN205491041U" includes a signal input unit and an earphone body, the earphone body includes an oval shell, and the inner cavity of the shell contains a loudspeaker. The loudspeaker includes a PCB board, a magnet assembly, a voice coil, and a diaphragm. The voice coil is connected with the magnet assembly and the diaphragm, and the PCB board is connected with the signal input unit. The peripheral contour of the magnet assembly is oval. The peripheral contour of the diaphragm is oval. Because the oval shell of the earphone with an oval loudspeaker has more space than the circular shell, the peripheral contour of the magnet assembly and the diaphragm is oval, and the magnet assembly and the diaphragm are in clearance fit with the inner cavity of the shell, realizing the maximum area of the diaphragm and the magnet assembly. The sound radiation power of the loudspeaker is proportional to the equivalent radiation area and the magnetic field strength, the equivalent radiation area is equal to the working area of the diaphragm, and the magnetic field strength is proportional to the volume of the magnet. Therefore, the maximum area of the diaphragm and the magnet assembly brings higher sound radiation power and better sound quality.

[0004] However, for the above-mentioned earphone with an oval loudspeaker, although the sound radiation power of the loudspeaker is proportional to the equivalent radiation area and the magnetic field strength, the equivalent radiation area is equal to the working area of the diaphragm, and the magnetic field strength is proportional to the volume of the magnet, so the maximum area of the diaphragm and the magnet assembly brings higher sound radiation power and better sound quality, there are still the following obvious defects in the use process: the handle part of the above-mentioned earphone is vertically fixed and will generate wind resistance in the movement, which will cause the earphone to be easily loose and fall off when worn in the ear canal.
