Description

Bone conduction vibrator of bone conduction and airway hearing

The present invention relates to an oscillator, which is an acoustic vibration transducer that converts a voice signal given as an input into vibration, and in particular, in the case of a hearing impaired person who has an omnidirectional deafness by inducing bone conduction hearing and airway hearing, using normal hearing hearing. The case of phosphorus relates to a bone conduction oscillator for both bone conduction and airway hearing, which is used as a cuff of a bone conduction phone to make a telephone call using airway hearing.

Since the conventional handset of the general telephone is a handset of an airbag made of a speaker, a hearing impaired person with a total voice hearing loss cannot actually make a telephone call with the general telephone.

Accordingly, in view of the fact that the hearing impaired person can perceive the voice signal through the vibration of the bone, a bone conduction phone employing a bone conduction vibrator as a handcuff has been proposed, but even in this case, an airway handset employing a general airway handcuff Because the two models of the bone conduction handset employing the bone conduction handcuff for the hearing and bone conduction only are kept or adopt only the bone conduction handset, the phone itself is bulky and expensive, In this living house, there is a problem that it is somewhat inconvenient to use together with a separate telephone.

However, in order to solve such a problem, Patent Registration No. 96-103913 by the present applicant has been proposed to solve the above problem. That is, the bone conduction vibrator according to the present invention has the advantage of having a parabolic diaphragm that can compensate for hearing impairment in the high frequency region, but the diaphragm can maintain a certain level of elasticity to protect the vibrator from external impact. Since the material must be used, there is a problem that the airway characteristics are relatively degraded.

Accordingly, the present invention has been made to solve the above problems, by adopting the principle of operation of the general speaker and the small speaker unit and the cross-shaped diaphragm causing bone conduction hearing and airway hearing, listening to the vibration sound by bone conduction hearing as well The purpose of the present invention is to provide a bone conduction vibrator that can listen to a voice signal by using normal hearing aid airway hearing.
