Description

Memorandum Book Hearing aid Sickle field

The present invention relates to a hearing aid, more specifically, a hearing aid used when a person with a hearing impairment has a conversation or watches a television, or has a conversation in a fan situation. The present invention relates to a hearing aid using a compact and high-performance bone conduction speaker. Background leak ''

Conventionally, humans with hearing impairment have S-conversations and watch TV: hearing aids have not been used as hearing aids in ^. The hearing aids are generally air-conducting and are attached to the ears and shelves. Therefore, it is not suitable for use as an official for the purpose of listening to only the necessary sounds, such as listening to and listening to television sounds, and talking with specific people.

As described above, in the past, humans with a sense of hearing impairment S had a conversation or watched television: ^^ In the past, there was no hearing aid suitable for listening only to the sounds that were mainly needed. Ii shall provide a hearing aid suitable for such use. In particular, the present invention provides a compact, high-performance, IS-based hearing aid that uses a bone conduction speaker that is architecturally positive. Disclosure of the invention

An embodiment of the present invention will be described with reference to a drawing of f dimensions. The hearing aid according to the present invention includes the chair I and the speaker part 2 connected to the remote 151.

The book # ¾1 includes a microphone 3, a vineyard switch 4, a volume haze knob 5, and the like. In addition, an amplifier and a battery that stores the amplifier are built in. The side of the book # 1 has a speaker cap, and preferably has an audio cable. (See Figure 3).

The speaker part 2 consists of a bone conduction speaker 8, a knob on one side thereof, a cable 10 and a force, and the connector 11 of the cable 10 is completely solved |こと Connected to book 1 by inserting it into child 6.

The audio cable connected to the audio cable connection eaves 7 is connected to the audio output of the crane output device. Needless to say, Diocable is an input means for inputting the word from the sound output device to the real solution (51. The sound output device includes audio signals such as televisions, CD players, and radio receptions) The output of ^ f symbols such as audio signals from the audio output terminal is included.

The above-mentioned speaker part 2 is a force S that is used by holding the hand 159 by hand, and this force can be used in a node-free manner using a headband. That is, one end A headband 13 provided with an inlet 14 is provided, and the vehicle i¾9a of the gripping section 9 is inserted into the outlet 14 (see FIG. 2).

In addition, the speaker part 2 has ear hooks 16 attached to both ends of the curved material 15 turned around the back of the head, and one or both of the sculptures I, and the bone conduction speaker 8 in the cutout 16. Can be configured as a headset 17] (see Fig. 3). Further, the speaker section 2 may be attached to the temple of the experiment (usually a temple, but also in the middle). In that case, it is possible to return the speaker part 2 to the vine.

Next, the bone conduction speaker 8 shown in FIGS. 4 to 8 and suitable for use in the present invention will be described. The bone conduction speaker 8 is composed of a yoke 21 having a mid-sized table 22, a split magnet 24 disposed outside a donut-shaped voice coil 23 surrounding the mid 2 2, and a yoke 21. It is composed of b-plate 25 attached to plate-solid 26. The yoke 21 is slightly larger than the voice coil 23 and has extensions in four directions. Two opposing parts of the ft ^ are magnet installation parts 27 and 27, and the other two are vibration plate fixing parts 28 and 28. A magnet 24 of S ^ i, which is in contact with the voice coil 23, is fixed to the magnets 27, 27, respectively. The magnet 24 may have a shape that curves along the voice coil 23.

ί Leak plate fixed; ¾¾ 26, 26 are fixed vertically to the plate fixed erection portions 28, 28 of the yoke 21. The board 25 is fixed at the center. It has a hole 29 for making. As shown in FIG. 8, the tm plate 25 has the same shape as the yoke 21 and has four protruding sides. 8, the upper and lower protruding portions have through holes 30 and 30 corresponding to the stop holes 29, respectively. Further, in FIG. The operation plate 25 is fixed to the fixed members 26 and 26 via spacers 32 by screwing screws.

A plate yoke 33 is attached to the plate 25. The plate yoke 3 3 extends along the central opening 3 1, and the portion located inside the central opening 3 1 is made thick, so that its upper surface and the vertical plate 25 are usually flush with each other. The thin part is fixed to the back surface of the leak plate 25 by brazing or the like. That is, the plate yoke 33 is fixed to the vibrating plate 25 only at the thin portions at both ends, and the middle thick portion is placed in the central opening 31 so that it can be excited. In the middle thick part of the plate yoke 33, usually two toughs 34 are formed, and by screwing the screws 36 into the housing 35 at the time iii, the speaker 37 as a whole is nozed 35 It can be attached to. The housing 35 can be divided into upper and lower parts.

At the time of the thread I3t, the bone conduction speaker 37 is attached to the housing 35 so as to float in the housing 35 via the plate yoke 33. Thus, since the sound generated by the application of the voice or the; -Dio input signal is {5} applied to the housing 35, the bone conduction speaker 37 can be difficult with high efficiency. In addition,: ^ of this fushige is divided into magnets 24 (conventional ones are circular and the case is wrapped around the outside). They are arranged concentrically and do not overhang. Therefore, the configuration becomes compact.

When the hearing aid according to the present invention is used in a conversation, ^ gives a book to the person to talk to and speaks into the microphone 3, and the person holds the bone extraction speaker 9 and raises the bone conduction speaker 8 near the force. Press lightly on several places and select the most listened place. Adjust the volume by turning the volume knob 5 on * 1.

To determine the age at which you watch TV, replace one end of the audio cable with the Diode Cable 7 and sell the other end to the audio output terminal on the back of the normal TV, as described above. Then, the bone conduction speaker 8 is brought into contact with the head via the head band 13, the head set, the vine of the experiment, or the like. Industrial applicability

The present invention is exactly as described above, and is used for hearing impaired people to talk or watch television, and for people with normal hearing to talk under stepping conditions. It is suitable for.
