HEARING ASSISTIVE AID, WHICH IS STERILIZING CHARGER FOR PUBLIC USE

Technical Field

[1] This idea is for 'Hearing Assistive Aid, which is sterilizing charger for public use'. It is hearing assistive aid that old man, who hearing ability is not good or hard of hearing people can use easily together in public facilities etc.. This has the form that everybody can use easily without putting earphone or hearing aid directly in inside of the ear in order to have the convenience in public use. And UV sterilization function is included in stand-type charger, so many people can use this 'Hearing Assistive Aid, which is sterilizing charger for public use' easily and cleanly.

[2]

Background Art

[3] Existent hearing aids have developed & produced by individual's exclusive use that only individual has. In other words, it was, for the most part, put inside of the ear and used in pocket type, behind the ear type, in the ear type etc. according to individual's hearing's characteristic.

[4] But, it was not suitable that public citizens use it together by such structural form.

Because earhole's size differs in people, so it is hard to use and very troublesome and not hygienic that many people use one earphone jointly. Also sterilization function of existent hearing aid is limited to small-sized individual's hearing aid, so the following methods are considered. - the method, that the user puts hearing aid to special sterilization device and then sterilizes it OR the method, that doing nano silver coating and then sterilizes etc..

[5]

Disclosure of Invention Technical Problem

[6] The purpose of this idea is in order that hard of hearing people do as can use

'Hearing Assistive Aid, which is sterilizing charger for public use' easily & conveniently in public facilities etc. It's structure, external appearance, function etc. were made conveniently to use in order that various users can use it without explanation for using method specially. And it is applied DSP (Digital Signal Processing) for hearing assistive aid's function and then maximized characteristic hearing function of noise exclusion and voice definition etc.. and also it was made so that can be charged and sterilized at the same time for hygiene and convenience. It can be converted outside audio signal of high-sensitive microphone or cellular phone to magnetic induction

signal and delivered by using coil for hearing aid compatibility certification and also have technological assignment that sterilizing charger made by built-in type.

[7]

Technical Solution

[8] To achieve above stated purpose, this 'Hearing Assistive Aid, which is sterilizing charger for public use', is achieved sterilization and charge together through charger, which is included sterilizing function in order that old man and hard of hearing people can use it easily in public facilities etc., so everybody can use it always. And it was applied coil for hearing aid compatibility certification so that people, who put individual hearing aid, can hear the sound clearly without howling when they use this 'Hearing Assistive Aid, which is sterilizing charger for public use' or when they get a call (though they use this hearing assistive aid together with their individual hearing aid). Also if connect it with outside sound device such as cellular phone etc. by using special cable, do as can hear wishful sound clearly without interference of surrounding noise.

[9] The composition of this idea can be explained dividing into hearing assistive aid part and sterilizing charger part greatly and hereafter, explains desirable enforcement instance of this idea which do attached drawings by reference in detail.

[10] Figure 1 is a whole drawing that hearing assistive aid part (1) and sterilizing charger part (2) are combined. Figure 2 (hearing assistive aid) is consisted of speaker part (5) that can hold it in user's hand easily and put on user's ear and then use, switch (4) that controls ON/OFF & volume, and cable jack (6) that can connect with outside audio device directly and hear, PUSH button (7) of power ON/OFF for user's convenience. Figure 3 is sterilizing charger part, when charging, it sterilizes speaker part (5) which touches in ear of people through UV - LED (Light Emitting Diode) or UV Lamp (8). Figure 4 is another whole drawing that another shape's hearing assistive aid part (1) and sterilizing charger part (2) are combined.

[11] As is illustrated to drawing 5, organic combined relation of components for inside necessary function is as follows ;

[12] In hearing assistive aid department (9), Audio selection department (12) applies high-sensitive nondirectional microphone and selects microphone input (10) that inputs surrounding audio signal or audio input (11) that inputs audio signal of external equipment. This is passed by DSP (Digital Signal Processing) department (13) and converts analog audio signal to digital signal through A/D converter(14) and handles noise filter, audio feedback, voice definition, AGC function etc.. through DSP processing department (15) and it is converted to analog signal again through D/A converter(16) and outputted. Outputted signal changes the size of audio signal that

applies manual volume through audio volume department (17). This transmits audio signal to last audio amplifier (18) of low electric power's characteristic through micro speaker (19) more than 120 dBs or coil for hearing aid compatibility certification (20) through induction coil of hearing aid for individual. In power controlling department (22) through charging terminal (21). it controls power ON/OFF of hearing assistive aid and battery charging department (23) improves the stability of battery by applying battery charge of overcharge, over discharge etc. and protection circuit. Power department (24) applies Li-Polymer battery, so minimized danger of explosion.

[13] Sterilizing charger department (25) applies AC/DC adaptor (26), so outputs DC power voltage and battery charging department (27) does quick charge function that is suitable to Li-Polymer battery's characteristic and overcurrent's break, countercurrent's prevention and battery connection existence and nonexistence checking. When inputs battery connection signal in battery charging department (27), controlling department (28) runs ultraviolet rays sterilization department (30) and inspects battery charging state. Indication department (29) displays battery charging state and charging's completion state. Ultraviolet rays sterilization department (30) produces ultraviolet rays wave using UV-LED or UV Lamp and runs when hearing assistive aid (1) is placed on it.

Advantageous Effects

[15] As described above, this 'Hearing Assistive Aid, which is sterilizing charger for public use' is hearing assistive aid that is old man, who hearing ability is bad or hard of hearing people can use easily in public space such as public institution, station, terminal, bank etc.. So, people who hearing aid did not have or people who did not obtain the desired effect of hearing aids for individual because of public space's peculiarity though they put hearing aid for individual, can hear wishful sounds well and talking partner might not shout loudness. So this 'Hearing Assistive Aid, which is sterilizing charger for public use' will be help to make agreeable environment of public space. Also when taking a serious view of individual's health like nowadays, Sterilizing Charger for hearing assistive aid that is including sterilization function for prevention of bacterial infection and shape/structure that do not need special explanation for use may give the convenience to all of the administrator or user. And it is possible to use that connects with cellular phone or other sound device directly according to need, so the user can hear wishful sounds clearly without disturbance of surrounding noise.
