A bone conduction sound generating device for a rear-mounted bone conduction earphone

Abstract

The invention relates to a bone conduction sound production device for a rear-worn bone conduction earphone. The bone conduction sound production device comprises a bone conduction sound producer anda mounting part thereof. The mounting part comprises a front cover surface and a rear cover surface. A flange is set on the inner wall of the front cover surface. The bone conduction sound producer comprises a bone conduction vibrator and a bone conduction vibrator fixing structure. The bone conduction vibrator fixing structure comprises a front cover and a rear cover. The front cover is a cylinder body covering the front end of the bone conduction vibrator and stretches out from an opening of the front cover surface of the mounting part. The rear cover comprises a rear cover cylinder coveringthe rear end of the bone conduction vibrator, a supporting part which is set on the cylinder wall of the rear cover cylinder and is vertical to the cylinder wall of the rear cover cylinder, and a connecting part which is set on the external edge of the supporting part, is parallel to the cylinder wall of the rear cover cylinder and is connected with the flange. According to the bone conduction sound production device provided by the invention, the bone conduction vibrator is stably mounted in the bone conduction vibrator fixing structure and the bone conduction vibrator fixing structure is connected with the mounting part, so the integrated sound quality of the bone conduction sound production device is good and the sound is clear.

Description

technical field [0001] The invention relates to a bone conduction sound generating device of a rear-mounted bone conduction earphone, which belongs to the technical field of earphone equipment. Background technique [0002] The back-mounted earphone is worn on the head through the support frame, and the earpiece is attached to the ear to listen to the sound without plugging in the ear hole, which avoids the discomfort caused by the earplug in the ear, while the traditional back-mounted earphone uses It is made of the principle of air vibration, and there are the following problems: (1) When the performance of the human eardrum decreases with age or disease, it will cause hearing impairment to the person; (2) the use of this earphone cannot hear the sound of the outside world , It is easy to produce danger when driving or crossing the road; (3) long-term use of this earphone at high volume has an impact on people's eardrums, can cause people's tinnitus, and seriously can caus...
