DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an earphone microphone unit used by being connected to a mobile telephone.

[0002]

2. Description of the Related Art Earphone microphone units are already known. This is configured such that an earphone and a microphone and an earphone microphone terminal are connected to each other by a main signal cable. In this earphone microphone unit, the sound to be output from the handset of the mobile phone is output from the earphone because the earphone microphone terminal is detachably connected to the earphone microphone terminal of a mobile phone such as a mobile phone or a PHS. And the voice to be input to the mobile phone's handset can be input from the microphone.

[0003] Two conventional examples of this type of earphone microphone unit are disclosed in JP-A-2000-236374. Each of the conventional examples includes a sub signal cable connected to a main signal cable and connected to audio equipment such as a recording / reproducing apparatus. In one conventional example, only the sound signal to the earphone, that is, only the signal representing the voice of the other party is transmitted to the audio equipment via the auxiliary signal cable, whereby the voice of the other party is transmitted by the audio equipment. Will be recorded. On the other hand, in the other conventional example, an audio signal to the earphone, an audio signal from the microphone,
That is, a signal representing the voice of the user of the mobile phone is synthesized and transmitted to the audio equipment via the auxiliary signal cable,
As a result, the sound of the other party and the voice of the user are recorded by the audio device.

Japanese Patent Application Laid-Open No. H11-220554 discloses another conventional example. This conventional example also has a sub signal cable connected to the main signal cable and connected to the audio equipment, similarly to the above two conventional examples. However, in this conventional example, the auxiliary signal cable is
It is used to transmit the sound reproduced by the audio equipment to the earphone.

[0005] In short, these prior arts are a sub-signal cable detachably connected to an audio device that performs at least one of recording and reproduction of sound, and include a sound signal to an earphone and a sound signal from a microphone. Is connected to the main signal cable to enable at least one of the above to be transmitted to the audio equipment and to transmit the audio signal output from the audio equipment to the earphone.

[0006]

In these conventional examples, the auxiliary signal cable is always connected to the main signal cable,
It is not possible to remove the auxiliary signal cable from the main signal cable.

However, when a main signal cable is used, a sub signal cable is not always used. That is, for example, when a mobile phone is used in a hands-free state using an earphone, a microphone, and a main signal cable, it is not always necessary to record the voice of the mobile phone with an audio device. It is.

As described above, in these conventional examples, the sub-signal cable is connected to the main signal cable regardless of whether or not it is necessary to use the sub-signal cable. For example, there was the problem that the sub-signal cable would be a hindrance to the user of the mobile telephone if it was not necessary to use the sub-signal cable.

[0009]

Means for Solving the Problems and Effects of the Invention In view of these circumstances, the present invention has been made to solve the problem that the auxiliary signal cable can be easily prevented from being in the way. As a result, the following aspects are obtained.
