Embodiment Construction

[0018] see figure 2 . The bone conduction and air conduction vibrator of the present invention includes a housing 1, a lead wire 2, a pole shoe 3, a permanent magnet 4, a coil 5 and a diaphragm 6, and the housing 1, a lead wire 2, a pole shoe 3, a permanent magnet 4, a coil 5 and The central axes of the vibrating membranes 6 are all coincident, that is, coaxial. Both the permanent magnet and the pole piece are magnets, which together form a magnetic circuit system.

[0019] The center of the housing 1 is hollow, and the pole piece 3 is located in the hollow center of the housing, and the center of one end thereof is recessed inward to form a receiving space 31 . The permanent magnet 4 is placed in the center of the accommodation space 31 .

[0020] The outer edge of the vibrating piece 2 is fixed on the lower end of the housing, and the inner edge of the vibrating piece 2 is fixedly connected to the other end of the pole shoe 3 . When the vibrating plate 2 vibrates, it dr...

Abstract

The invention discloses a bone conduction and air conduction earphone. The bone conduction and air conduction earphone comprises a hollow shell (1) and a lead (7) for inputting electrical signals, wherein a pole piece (3) is arranged in the hollow centre of the shell; one end surface of the pole piece (3) sinks inward to form an accommodating space (31) in which a constant magnet (4) is arranged; one end of the shell is fixedly connected with the outer edge of an vibrating reed (2); the inner edge of the vibrating reed (2) is fixedly connected with the other end of the pole piece (3); a vibrating membrane (6) is fixed at the other end of the shell; the inner side of the vibrating membrane (6) is connected with a coil (5) which is embedded in a gap formed between the pole piece (3) and the constant magnet (4); gaps are reserved between the coil (5) and the constant magnet (4) and between the coil (5) and the pole piece (3); and the coil (5) is connected with the lead (7). The bone conduction and air conduction earphone can be used by normal people and deaf people.

Description

technical field [0001] The invention relates to a vibrator and an earphone with the vibrator, in particular to a bone conduction and air conduction vibrator and an earphone thereof. Background technique [0002] see figure 1 , the structure of the human ear is divided into three parts: the outer ear 81 , the middle ear 82 , and the inner ear 83 . Among them, the outer ear receives the air vibration generated by sound from the outside world; the tympanic membrane 87 of the middle ear vibrates under the action of air vibration, and causes the vibration of the three auditory ossicles - the cone 84, the stapes 86 and the incus 85, and transmits the sound. To the inner ear; the inner ear 83 can generate nerve impulses, which are converted into nerve energy along the auditory nerve, and from there the sound information is transmitted to the brain. If the tympanic membrane or the auditory ossicles are obstructed, the human ear will not be able to hear the sound of the outside wor...
