Description
Technical field
The utility model relates to hearing aid technology, particularly relates to a kind of hearing aids protective sleeve.
Background technology
Hearing aids is one and contributes to hearing disabilities person and improve dysacousis, and then improves and the instrument of his conference communicative competence, unit and instrument etc.Allly in a broad sense effectively the various devices that sound imports ear into can be seen as hearing aids, say that hearing aids is exactly an electroacoustic amplifier in the narrow sense, deaf person is heard sound amplification by it originally to can not hear clearly, unheard sound, this device is exactly hearing aids.Hearing aids today is mainly divided into simulation hearing aids and digital deaf-aid two kinds.Wherein simulation hearing aids is the hearing loss curve shape regardless of patient, carry out unified amplification, and digital deaf-aid compensates accurately according to the hearing loss curve shape of patient to sound.Because the residual hearing protected effect of digital deaf-aid to the compensation effect of hearing and patient all comparatively will simulate hearing aids better, so the main product sold in Present Domestic market is based on digital deaf-aid.Hearing aids can be divided into ear-level hearing aid again from the angle of wearing position and profile, hearing aids, duct-type hearing aids, complete duct-type hearing aids, the hearing aids a multitude of names such as 100% stealthy hearing aids, but the operation principle of all electronic hearing aids is the same.Any hearing aids all comprises 6 basic structures.1. microphone (microphone or microphone) receives sound and it is converted into electric wave form, namely acoustic energy is converted into electric energy; 2. amplifier amplification signal (transistor amplifying circuit); 3. earphone (receiver) is acoustical signal (be namely acoustic energy electric energy conversion) transform electrical signals; 4. ear mold (earplug) inserts external auditory meatus; 5. volume control switch; 6. power supply is for the zinc-air cell of amplifier.
At present, there is the deaf youngster 800,000 that becomes deaf in China, and annual increases newborn deaf youngster 2-3 ten thousand, and hearing aids to carry out the training of sense of hearing speech rehabilitation be avoid deaf youngster because of deaf effective ways of disabling.Deaf youngster's hearing aids price costly, is often propped up 1-2 ten thousand yuan, how available protecting and avoid that hearing aids is fallen, shake etc. damages is the realistic problem that deaf youngster and the heads of a family face.Therefore, the sanitary condition improving them is very important.Therefore, for solving the problem, spy provides a kind of new technical scheme.
