JPH0336899A - Portable acoustic equipment - Google Patents

Abstract

PURPOSE:To prevent the consumption of a battery based on a switch left unswitched by adopting such a structure that a power switch is closed only in the operating state to activate a portable acoustic equipment and the switch is opened when the equipment is removed. CONSTITUTION:The position of an earphone 8 is adjusted along a spring 7 and when a main body 1 is placed to the top of the head, the earphone 8 touches both ears. A lever 3 at a position A projecting from the main body 1 is displaced and moves to a position B when the lever 3 is in contact with the head, and a button 6 of a microswitch is depressed to turn on a power switch. When the main body 1 is removed from the head, the lever 3 is restored from the position B to the position A thereby turning off the power switch. Thus, when a hearing aid is set to the head, the power is immediately turned on and when the hearing aid is removed, the power switch is immediately turned off. Thus, the consumption of the battery due to the switch left unswitched is prevented without excess operation for the user.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power switch for equipment used by people with some kind of physical disability, such as hearing aids and ultrasonic reading equipment for blind pedestrians.

[Conventional technology]

For example, if we take the example of a hearing aid, although it has a sufficiently effective performance in terms of acoustic technology, the switch is extremely small (it displays ON and OFF, and a grain of rice is a 'It' switch), so it is difficult for elderly people and others with poor memory to use it. Very often people forgot to turn it off after use, and the battery ran out and stopped working in a short time.

[Problem 1 to be solved by the invention: The device should be configured so that it can be turned on by wearing it and turned off by removing it, without the user of the device having to turn the switch on or off.

[Means for solving problems]

For example, in the case of a hearing aid, the part where the hearing aid is attached to the human body,
A contact is provided that protrudes toward the human body, and the power switch is turned on by displacement due to direct or indirect contact with the human body.
N or turn it OFF.

[For production]

To illustrate and explain with reference to FIG.
Position it at position (A) protruding from 1).

When the lever (3) is pushed and displaced by your body and reaches position (B), press the button (6) of the power microsinch (5) to turn on the power switch and remove the device from your body. , the lever (3) is restored from position (B) to (A), the button (6) is restored to its previous position, and the power switch is turned OFF.
become.

The lever (3>) is normally located at the (A) position shown by the solid line, and is configured so that when pushed by an external force, it moves to the (B) position and returns to the (A) position when the external force is removed.

〔Effect of the invention〕

The power switch is turned on and the device operates only when it is in use, and the switch is turned off when removed, so there is no need to forget to turn it off, and even people with reduced attention, writing, and Q-power can use the device without failure. .

〔Example〕

FIGS. 1 and 2 show examples of hearing aids that are worn on the head.

The main body (1) houses a microphone, an amplifier 111 circuit, a power supply, an output terminal, etc. inside, and has springs (7) on both sides.
Earphones (8), (8) are connected via (7), and signals are transmitted from the main body (1) to the earphones (8), (8) via cords (9), (9). The position of the earphones (8), (8) is the spring (7), (
7) so that when the main body (1) is placed on the top of the head as shown in Figure 2, the earphones (8) and (8) are in contact with both ears.

If the main body (1) is hung from the neck or placed in the pocket of the chest when in use, the yaws 1" (9) and (9) extend long from the chest to the ears and become intertwined, causing inconvenience to the user. However, as in this example, if the cords (9) (9) are short and placed along the springs (7), (7), or stored inside the springs (7), (7), they will not get tangled and will be easier to handle. easy.

A feature of the present invention is that when the hearing aid is placed on the head as shown in FIG. 2, the power is turned on immediately, and when it is removed, the power is turned off immediately, so that the user does not have to perform any extra operations.

Since the main body (1), the spring (7), and the earphone (8) can all be made extremely light and small, it is easy to attach them to the head as in this example.

Lever (3) in position (A) protruding from main body (1)
When it comes into contact with the head, it will be displaced and move to position (B). Push in the micro switch button (6) and turn the power switch to O.
When the main unit (1) is removed from the head, the lever (3) returns from the (B) position to the (A) position and the power switch is turned OFF.
It becomes F.

Figure 3 shows an example that is suitable for earphones inserted into the ear canal.
The lever (3
) occupies position (A) when not in use, hits the wall of the ear canal when inserted into the ear canal, moves to position (B), and turns on the power switch.

If you remove it from your ears, the switch will turn off.

[Fig. 4] shows an example in which the present invention is applied to earphones that are hooked onto the ear.

The lever (3) protruding from the main body (1) occupies position (A) when not in use, but when in use it is pushed against the upper edge of the ear (B).
) position and press button (6) of micro switch (5).
) to turn on the power switch, then remove it from your ear to restore it and turn it off.

Turn on the power without using a micro switch Other switch mechanisms that turn off may also be used.

It is sufficient to provide a protruding portion that is displaced when worn on the body, and to turn the power on and off by the displacement of the protruding portion.
