Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handset used for a telephone, and more particularly to a handset with an earphone that allows an earphone to project from the earpiece when it is difficult to hear.

[0002]

2. Description of the Related Art Generally, a handset used for a telephone is provided with an earpiece at a portion that touches the ear and a transmitter at a portion corresponding to the mouth. In addition, there are various situations in which the handset is used, for example, when the voice from the earpiece cannot be heard due to surrounding noise or noise, or the volume from the earpiece is insufficient when the hearing-impaired person uses the voice. There are cases.

Therefore, in the prior art, Japanese Laid-Open Patent Publication No. 3-36857.
As described in Japanese Unexamined Patent Publication No. 9-9, the volume of the earpiece can be adjusted so that the volume can be easily heard.
As described in Japanese Patent No. 0553, a receiving portion is provided with a convex portion,
By applying this convex portion to the ear, the space between the earpiece and the ear is narrowed to make it easier to hear the voice.
As described in Japanese Patent No. 547, there is an earphone and its cord that can be stored in a handset so that the earphone can be used appropriately.

[0004]

However, since the one disclosed in Japanese Patent Laid-Open No. 3-36857 simply enlarges the voice from the receiving section, when the voice is used in a loud environment, the surroundings are reduced. There is a problem that sound may be leaked, especially when used on a mobile phone or a public telephone, which may cause trouble to others.
Furthermore, if the voice is made too loud, the sound may be distorted, making it more difficult to hear.

In Japanese Utility Model Laid-Open No. 3-90553, a convex portion narrows the space between the ear and the receiving portion, and the audibility of voice is slightly improved, but external noise is still present. Since noise is likely to be heard in the ear, it is susceptible to such noise and the like, and there is a problem that it is difficult to hear voice in such an environment.

Further, in the one disclosed in Japanese Utility Model Laid-Open No. 1-88547, it is troublesome for the user to take out and store the earphone and its cord, and since the earphone is connected to the handset via the cord, There is a problem that the code becomes an obstacle when used.

[0007] Therefore, an object of the present invention is to provide a handset with an earphone capable of making a voice easily audible by protruding the earphone from a receiver by a simple operation and inserting the earphone into an ear. .

[0008]

SUMMARY OF THE INVENTION A handset with earphones according to the present invention is an earphone provided so that the earpiece can be in a protruding state or a housed state, and an operating section for selectively setting these states. And a drive means for switching the earphone from one of the projecting state and the stored state to the other state in accordance with the setting mode of the operating section and holding the earphone, and a motor or the like is used as the driving means. I am using.

[0009]

As described above, since the earphone is provided so as to be in the protruding state and the housed state in the earpiece, when the user inserts the protruding earphone into the ear and uses the earphone, noise from the ear is generated. It is possible to prevent from entering and to hear the voice clearly. Moreover, the use of earphones prevents the sound from leaking to the surroundings.

Embodiments of the present invention will be described with reference to FIGS. In the figure, 1 is a handset, 1a is a code,
2 is a receiver, 3 is a transmitter, 4 is a receiver unit, 5 is a transmitter unit, 6 is an earphone, 6a is a guide groove, 7 is a tubular part, 8 is a motor (driving means), 9 is an operating part. Reference numeral 10 is a gear with an arm, 10a is an arm portion, 10b is a guide pin, 11 is a bar gear, 12 is a large diameter gear, and 13 is a small diameter gear.

Here, the handset 1 is connected to a telephone body (not shown) by a cord 1a, and the handset unit 4 is attached to a portion inside the handset 1 corresponding to the earpiece 2.
A transmitter unit 5 is provided at a portion corresponding to the transmitter 3. The handset unit 4 converts a reception signal from the telephone body into a voice, and the handset unit 5 converts a voice of the user into a transmission signal.

A tubular portion 7 is provided at a substantially central portion of the earpiece 2, and the earphones can be moved in the tubular portion 7 so that the earpiece 2 can be in a projected state and a housed state. 6 is provided. This earphone 6
In the same manner as the handset unit 4, a reception signal from the telephone main body is sent to. A soft antibacterial resin is used for the surface of the earphone 6.

A motor 8 is used as a driving means of the earphone 6, and its concrete structure is as shown in FIG. First, as the small diameter gear 13 attached to the motor 8 rotates, the large diameter gear 11 rotates, and the rod gear 12 integrated with the large diameter gear 11 also rotates.

Subsequently, the rotation of the bar gear 12 causes the arm gear 10 meshing with the bar gear 12 to rotate, and the arm portion 10a also moves accordingly. Therefore, the arm 10
By associating the guide pin 10b provided on a with the guide pin 6a of the earphone 6, the earphone 6 is guided by the tubular portion 7 and moved by the movement of the arm portion 10a.

Further, the handset 1 has an operating section 9 for selectively setting the protruding state and the housed state of the earphone 6.
Is provided, and one of the projected state and the stored state is switched to the other in accordance with the setting mode of the operation unit 9. That is, depending on the setting mode of the operation unit 9, the motor 8
The earphone 6 is moved by switching the rotation direction of the earphone 6 and changing the moving direction of the arm portion 10a.

At this time, since the arm gear 10 meshes with the rod gear 12, the rotation of the arm gear 10 is restricted by the rod gear 12 even when force is applied to the arm gear 10, whereby the arm portion 10a also moves. As a result, the earphone 6 is held at its moving position, for example, the protruding position or the stored position.

The driving means of the earphone 6 is not limited to the motor 8 and various gears as shown in the drawing,
It is also possible to use a pressing force against a user's operation unit and a restoring force of an elastic body without using a motor, or to utilize the action of a solenoid. In these cases, it is necessary to provide a hook or the like to hold the protruding state and the stored state of the earphone 6.

The received voice needs to be at least emitted from the earphone 6 when the earphone 6 is projected.
Therefore, when the voice is always output from the handset unit 4 regardless of the protrusion and storage of the earphone 6, or when the earphone 6 is extended, the driving means is interlocked so that the voice is not output from the handset unit 4. Any of the above-mentioned switches may be provided.

Further, the earpiece unit 4 may not be provided in the earpiece 2 and the earphone 6 may output the received voice even when the earphone 6 is stored. Further, the position of the operation unit 9 is not limited to the position shown in the figure, and it can be provided at any position. Further, a volume for adjusting the volume of these reception volumes may be provided in a part of the handset 1.

The overall shape of the earphone-equipped handset 1 is not limited to that shown in the drawings.
