Description

TECHNICAL FIELD

[0001] The utility model relates to earphone technical field especially is earphone head beam and head -wearing earphone. BACKGROUND

[0002] The head beam is usually provided with a steel bar, which can reinforce the structure of the head beam and provide better elasticity for the head beam.

[0003] At present, the fixing of the head-wearing steel bar of some head-wearing earphones on the market is through the upper cover and the sheath support to clamp the steel bar up and down, and the limiting column is inserted into the steel bar to fix the steel bar. Because the steel bar groove between the head-wearing upper cover and the sheath support is usually larger than the thickness of the steel bar, when the head beam of the head-wearing earphone is expanded, the deformation degree of the head-wearing steel bar is slightly smaller than that of the plastic part, so that the steel bar will press the sheath, which not only affects the service life of the sheath, but also affects the wearing experience.

[0004] For example, Chinese patent application No. CN202021498045.3 earphone head beam and head-wearing earphone. Specifically discloses "earphone head beam, including steel bar, two head beam plastic parts respectively installed on the opposite ends of the steel bar, sponge part abutting between the two head beam plastic parts, and leather sheath; the leather sheath is sleeved on the outside of the head beam plastic part, the sponge part and the steel bar; one end of the head beam plastic part is provided with a pressing structure, and the other end of the head beam plastic part is provided with a fixed table; the steel bar is inserted between the pressing structure and the head beam plastic part, and the steel bar is fixedly connected with the fixed table". When the earphone head beam expands, the deformation degree of the steel bar will be smaller than that of the leather sheath, so that the steel bar will press the sponge, which affects the service life of the sponge and also affects the wearing experience.

[0005] For example, Chinese patent application No. CN201921360814.0 discloses an earphone head beam, which comprises a head beam body, a head arch fixedly installed on the head beam body, a fixing piece located on the side of the head arch away from the head beam body, and a sponge leather sheath fixedly connected with the fixing piece; the sponge leather sheath is located on the side of the fixing piece away from the head arch; the fixing piece has a first clamping piece; the head beam body has a second clamping piece clamped with the first clamping piece; the head beam body is an elastic plastic part and / or the fixing piece is an elastic plastic part. When the head beam expands, the bending degree of the head arch will be smaller than that of the head beam body, and the head arch will also press the sponge leather sheath, which affects the service life of the sponge leather sheath and also affects the wearing experience.
