Detailed Description

The embodiment of the application provides a bone conduction earphone for solve among the prior art conduction earphone and lead to the user uncomfortable when wearing because of structural design is unreasonable, unsuitable permanent wearing and the lower technical problem of steadiness when wearing.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 3, an embodiment of the present invention provides a bone conduction earphone, which includes a front cavity 1, a support 2, a microphone 3, a sound guide tube 4, soundproof cotton 5, a speaker 6 and a rear cover 7; the front cavity 1 is connected with the rear cover 7 in a clamping combination mode, the microphone 3 is arranged in the front cavity 1, the support 2 is arranged in the front cavity 1, and the support 2 is sleeved at one end of the microphone 3 and used for fixing the position of the microphone 3; the sound guide tube 4 is arranged inside the front cavity 1, and the soundproof cotton 5 is sleeved on the sound guide tube 4; speaker 6 establishes in the inside of back lid 7, and after preceding cavity 1 carried out joint aggregate erection with back lid 7, speaker 6 with the one end of leading note pipe 4 is connected.

The side of the ear-entering part of the front cavity 1 protrudes upwards to form a protruding part, and the protruding part can be used for propping against ears when the earphone is worn, so that the wearing stability is greatly improved; one end of the front cavity 1, which is close to the auditory canal of a human body, is inserted into the ear, and a mushroom-shaped soft rubber sleeve is arranged at the end, which is close to the auditory canal of the human body, of the front cavity, and the soft rubber sleeve can be changed into a shape adapting to the auditory canal according to the insertion, so that the wearing comfort is improved, and the wearing stability is improved; the soundproof cotton 5 is sleeved on the sound guide pipe 4, and in the conduction process of the sound guide pipe 4, the soundproof cotton 5 plays a role in preventing sound leakage and better conducts sound to a user; the loudspeaker 6 is connected with one end of the sound guide tube 4, so that the sound guide tube 4 can better conduct the sound emitted by the loudspeaker 6; the inner diameter of one end of the ear-entering part close to the human auditory canal is smaller than that of one end of the microphone, the sound transmission channel is narrow in front and wide in back, and sound transmission is more concentrated by utilizing the shape of the channel.
