Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a headset with a built-in battery.

[0002]

2. Description of the Related Art A headset in which a main body of a headset having a speaker is exposed to the ear canal opening by hooking an ear hook on the right or left ear has been known. In order to improve the stability (wearing stability) of the headset body when worn on the outer ear and the feeling of wearing that is related to pain and fatigue that occurs when wearing this kind of headset, use the ear hook Although it is beneficial to match the shape of the contour line of the inner circumference of the ear with the outer circumference of the auricle, there are individual differences in the shape of the ear, so the inner circumference of the ear hook should match the shape of the ear of each individual. There is a limit in matching the shapes of the contour lines.

As a built-in battery type headset having a built-in battery as a power source, it is known that the headset body, which is mounted so as to face the ear canal opening of the auricle, has a built-in battery. Then, not only is the size of the headset main body increased because it is necessary to secure a storage space for the battery inside the headset main body, but the weight of the battery is added to the weight of the headset main body. It becomes difficult to reduce the size and weight of the set body, and therefore there is a limit to improving the wearing stability to the ear.

Japanese Unexamined Patent Publication No. 2001-112081 discloses that
There is a description of headphones in which an ear hook is rotatably connected around a single axis to a headset body with a built-in speaker. According to this, the headset when the ear hook is hooked on the root of the outer ear is described. The position of the main body can be adjusted by shifting about one axis (first precedent example).

Further, in Japanese Unexamined Patent Publication No. 10-56697, an ear hook is connected to a headset main body containing a speaker, and a holder for accommodating a battery as a power source is attached to the ear hook so that the holder protrudes backward. There is a description of the electroacoustic transducer (second prior art example).

Further, Japanese Patent No. 29949929 discloses that
There is a description of an ear-hook type hearing aid in which a body case accommodating a battery as a power source is provided with an ear hook (third prior example).

[0007]

In the techniques found in the first and second prior art examples, as described above, the shape of the contour line of the inner peripheral portion of the ear hooking portion is adjusted according to the shape of the ear of each individual. Since there is a limit to the matching, in order to compensate for this point and improve the above-mentioned wearing stability and wearing feeling, it is necessary to consider the balance of the weight added to the ear at the time of wearing together with the shape of the ear hook. It may be beneficial to properly determine the appropriate weight balance.

However, as seen in the second prior art example, when a holder for accommodating a battery is attached to the ear hook portion so as to project rearward thereof, the weight of the holder or the battery accommodated in the holder causes the ear hook portion to move. The center of gravity comes to be located in the rear part of the root part of the outer ear. Also, a force is generated to rotate the ear hook. Therefore, a large load is applied to the root part of the outer ear, and it is not sufficient as a measure for reducing the pain and fatigue that occur when the user continues wearing the ear.

Further, in the second prior art example, it is assumed that a good wearing feeling can be obtained when the earpiece is attached to the outer ear and the headset body is properly exposed to the opening of the ear canal. , When the ear hook is attached to or removed from the outer ear, the headset body becomes a hindrance and good detachability cannot be ensured.

In the third prior art example, since the main body case accommodating the battery and the ear hook are formed so as to follow the outer peripheral shape of the base portion of the auricle, it can be said that the wearing feeling is improved.

The present invention has been made under the above circumstances, and when the ear hook is hung on the base of the outer ear and the headset main body faces the opening of the external auditory meatus, the balance of the weight applied to the ear is balanced. It is an object of the present invention to provide a headset with a built-in battery, which can achieve good wearing stability and can provide a feeling of wearing that does not cause much pain and fatigue by taking measures to improve the headset.

It is another object of the present invention to provide a built-in battery type headset which has a good wearing feeling and is excellent in operability for attaching and detaching to the outer ear.

[0013]

In the headset with a built-in battery according to the present invention, the headset main body can be exposed to the opening of the ear canal by hanging the headset main body with a speaker on the root portion of the outer ear. It has an ear hooking part and a battery accommodating part as a power source. The ear hooking portion is provided with the housing portion, and the weight of the headset main body is lighter than the weight of the ear hooking portion in which the battery is housed in the housing portion.

According to this, when the ear hook is hung on the root of the outer ear and the headset body is exposed to the opening of the ear canal, the weight of the ear hook and the accommodating portion are accommodated in the root corresponding to the inner side of the outer ear. While the weight of the battery is added, the weight of the headset main body facing the ear canal opening corresponding to the outside of the outer ear is lighter than the weight of the ear hook having the accommodating portion in which the battery is accommodated. Improves the mounting stability when hung on.

In other words, the weight of the headset main body is heavier than the weight of the ear hook portion because the conventional built-in battery type headset has the battery built in the headset main body. The built-in headset transfers the weight of the battery from the headset body to the ear hook by providing the battery holder in the ear hook, and by doing so, the wearing stability can be improved. Of.

In the present invention, the headset main body may include an antenna for transmitting a signal between the headset main body and the counterpart electronic device together with the speaker. According to this, since the antenna is built in the headset main body, the antenna is located away from the battery housed in the housing portion of the ear hook, and the radio wave radiation characteristic of the antenna is improved. .

In the present invention, the ear hook portion is a substantially arcuate member, and the inner peripheral portion of the substantially arcuate member has an outer peripheral auricle shape extending from the upper part of the root part of the auricle to the lower part to the lower part. The accommodating portion has a contour line along it, and the accommodating portion is continuously provided at a lower end portion of the ear hooking portion so as to form a shape that is smoothly continuous with the arcuate member, and the headset main body is provided with a microphone. In addition, it is desirable to adopt a configuration in which a sound collecting arm whose tip portion faces the user's mouth is connected.

According to this, the contour line of the inner peripheral portion formed by the ear hooking portion and the battery accommodating portion provided in the ear hooking portion follows the outer shape of the auricle, so that the wearing feeling can be maintained to some extent. Be done. In addition, the weight of the battery is added to the lower end of the ear hook that is connected to the battery housing, so the center of gravity of the ear hook is located below the root that is inside the outer ear. As a result, the rotational moment does not act on the ear hook, which helps to improve the wearing stability and wearing feeling. Furthermore, since the sound collecting arm is provided so as to face the mouth of the user, the voice of the user can be collected well.

In the present invention, it is possible to adopt a structure in which the headset main body and the base portion of the ear hooking portion are connected to each other so as to be capable of relative swinging around two axes orthogonal to each other. According to this, the headset main body can be moved in any direction with respect to the ear-hooking portion, so that the operability when the headset is attached to and detached from the ear is improved.

In this case, the headset main body and the base of the ear hooking portion open the ear hooking portion with respect to the headset main body and the opening / closing initial position where the ear hooking portion extends substantially parallel to the front surface of the headset main body. The first support shaft swingably connected to the open position, the turning initial position where the ear hook is opposed to the front face of the headset body, and the retracted position where the ear hook is retracted from the initial turning position. It is desirable that they are connected so as to be relatively swingable around two axes formed by a second support shaft that is swingably connected between them.

According to this, when the headset is attached to and detached from the ear, the headset main body is swung around the first support shaft with respect to the ear hooking portion to open or swing around the second support shaft. Since it is possible to shift the position by doing so, it becomes possible to easily attach and detach by performing such an operation. Nevertheless, after being worn on the ear, the headset body can be swung around the first support shaft to the opening / closing initial position, or swung around the second support shaft to the swiveling initial position. Therefore, it is possible to attach the ear hook to the base portion of the outer ear so that the headset main body can properly face the ear canal opening.

In the present invention, it is desirable that the diameter of the contact portion of the headset body with the auricle is 38 mm or less. In a headset with a built-in battery that is attached to the ear, a portion that contacts the outside of the outer ear provided in the headset body (corresponding to the contact portion).
The diameter of is preferably as small as possible. This is because if the diameter of the contact portion is too large, the contact portion crushes the ear itself in a wide range, which easily causes pain and fatigue and deteriorates the wearing feeling. If the diameter of the contact portion of the headset body with the auricle is set to 38 mm or less as described above, pain and fatigue do not occur so much, and the weight of the ear hook portion and the headset body described above does not occur. The feeling of wearing was able to be improved in combination with the action caused by the balance of the height.
