DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone,
More specifically, the present invention relates to an earphone microphone attached to a mobile phone and used away from the phone.

[0002]

2. Description of the Related Art It is possible to make a telephone call even when the main body of a mobile phone is put in a bag or a pocket.
Earphone microphones have been put to practical use. This earphone microphone is used as a convenient device because it can be used for hands-free communication if the earphone microphone body is clipped to clothing etc. close to the mouth of the user and the earphone is inserted in the ear. ing.

[0003]

However, in conventional earphone microphones, when a plug is inserted into an earphone microphone terminal of a portable telephone, a ring tone is emitted only from the earphone after that. If you don't wear it in your ear, you can't know the incoming call.

In some cases, a ring tone sounds on the mobile phone main body side even when the plug is inserted. However, if the ring tone sounds while the mobile phone is in a pocket or bag, the sound cannot be heard. In some cases, it may not be possible to determine whether one's own mobile phone is ringing or that of another person.

Some portable telephones have a vibrator function. However, if the portable telephone is in a pocket away from the body by wearing a loose jacket or the like or in a bag, the vibrator vibrates. Cannot detect it.

An object of the present invention is to provide an earphone microphone for a portable telephone that can notify an incoming call by light, sound, vibration, or the like even in such a case.

[0007]

According to the present invention, there is provided an incoming / outgoing / terminating operation circuit having an operation switch in a main body case and an incoming call to a connected mobile phone. An incoming signal sensing circuit that senses that, an incoming notification unit that operates by the output of the incoming signal sensing circuit,
A plug that includes a microphone and a power supply for supplying power to a circuit in the case, and is connected to the circuit in the main body case via a connection cord, and further connected to an earphone microphone terminal of the mobile phone via another connection cord. The problem is solved by using an earphone microphone for a mobile phone comprising:

Further, the above-mentioned problem is solved in the preceding paragraph, in that the incoming call notifying means is based on one of light emission, sound, and vibration.

Further, the above-mentioned problem is solved in the preceding two aspects, wherein the incoming call notifying means includes a plurality of light emission, sound, or vibration, and can be selectively used.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has a function of notifying that an incoming call has been received by light, sound or vibration in the main body case of an earphone microphone, so that the main body of the portable telephone is located in a bag or the like. This is useful when an incoming signal cannot be recognized.

The earphone microphone main body connected to the mobile phone main body by the connection cord has an incoming signal detecting circuit for detecting that there is an incoming call to the mobile phone, and an incoming call notifying means activated by an output of the incoming signal detecting circuit. Be prepared. As an incoming call notifying means, a light display notifying by light emission of an LED or a lamp, a vibration notifying by transmitting vibration of a vibrator or the like to a part of a human body, or a sound signal emitted from a speaker or the like. To be provided.

[0012] If the display is provided with a light display, even if the notification is made on a desk or the like in a state where it is separated from the body, it is possible to know the incoming call regardless of the surrounding noise. If it is provided with the vibration notification, the incoming call can be confirmed without disturbing the surroundings by holding the clip in a breast pocket or the like. Further, if an acoustic notification is provided, the notification can be made on a desk or the like while being separated from the body, and the incoming call can be recognized by ear even if the user is working on another job.

[0013] In addition, as the incoming call notifying means, a combination of three or more of the above-described light display, vibration notification, and sound notification is provided, and if it is selectively used according to the situation, the use range is further expanded. It will be.

The earphone microphone is connected to an incoming / outgoing / ending operation circuit having a switch for operation, a microphone for communication, a power supply to be supplied to a circuit in the case, and a circuit in the main body case via a connection cord. Since the earphone is provided with a plug connected to the earphone microphone terminal of the mobile phone through another connection cord, the function as the earphone microphone is perfect.
