Description

  The present invention relates to an earphone microphone device used for connection to a mobile phone.

  Earphone microphones are widely used so that a mobile phone can respond while driving a car. In recent years, stereo-compatible earphone microphones that can take music from a distribution to a mobile phone and enjoy the music have been used. On the other hand, this type of earphone microphone is provided with a reel body that allows the jack cord and earphone cord to be wound / drawn in the middle. It is also easy to handle because there is no long code.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an earphone / microphone device for a mobile phone that has a simple configuration and is excellent in functionality, is compatible with stereo, and can wind / draw a jack cord and an earphone cord.

  In this device, a jack cord connected to a mobile phone, a pair of stereo-compatible earphone cords, a reel body capable of winding / drawing each of the cords, a device main body incorporating the reel body, and the device There is provided an earphone / microphone device for a mobile phone comprising a microphone attached to a main body and a volume body for adjusting a listening volume attached to the device main body.

  According to the above configuration, it is possible to use a stereo-compatible mobile phone by connecting the jack cord end pulled out from the device main body to the mobile phone and attaching each of the earphone cord ends to the ear. By providing the volume body, the microphone can be effectively used for collecting voice while the apparatus main body is located near the mouth, and the stereo volume can be adjusted with the earphone.

  According to this device, the microphone can be effectively used in a compact form that can be wound up with the jack cord and the earphone cord when not in use, and the stereo volume can be adjusted with the earphone while being a simple configuration. An earphone / microphone device for a mobile phone having excellent functionality and extremely high practicality can be obtained.

  1 is an external perspective view of an embodiment of an earphone microphone device for a mobile phone according to the present invention, FIG. 2 is a front view thereof, FIG. 3 is a side view thereof, FIG. 4 is a plan view thereof, and FIG.

  The earphone microphone device 1 for a mobile phone is configured by connecting a jack cord 3 connected to a mobile phone to a device main body 2 and a pair of earphone cords 4 and 4 for stereo. A reel body 7 is provided in the apparatus main body 1 so that the respective cords 3, 4, 4 can be wound / drawn out.

  FIG. 6 shows a simplified configuration of the reel body 7, and rotating plates 13 and 14, which are integrated with winding shafts 10 and 11 on both sides opposite to the intermediate plate 9 fixed in the apparatus main body 1 side, are intermediate plates. 9, the periphery of the winding shaft portion 10 is a winding space S1 for the earphone cords 4 and 4, and the periphery of the winding shaft portion 11 is a winding space S2 for the jack cord 3. As described above, the rotating plates 13 and 14 are separately rotated, so that the cords 3, 4, and 4 can be independently wound and pulled out. Although the description of each of the rotary plates 13 and 14 is omitted, automatic winding means using a spring and a lock means, which are conventionally well-known techniques in a tape measure or the like, are integrally provided and arranged. As the reel unit 7, a conventional product of a type in which the rotating part is shared and the jack cord and the earphone cord are pulled out to the opposite side may be used.

  A connection switch 20 and a microphone 21 are provided on the upper surface of the apparatus main body 2, a volume body 22 for adjusting the listening volume is provided on one side, and further, a clothing for the apparatus main body 2 is provided on the rear side. A clip 24 is attached. It should be noted that the electrical connection in the mobile phone earphone microphone device 1 is appropriately made based on a known technique so as to enable the operation described below.

  The operation of the mobile phone earphone microphone 1 will be described below. In use, the jack cord 3 is pulled out to a desired length, and the jack 30 is connected to, for example, a mobile phone in a bag. In this state, the apparatus body 2 is connected to the chest pocket portion of the jacket using the clip 24. The earphone cords 4 and 4 with appropriate lengths are pulled out, and the earphones 41 and 41 are respectively attached to the ears. At this time, the earphone cords 4 and 4 can be pulled out in an arbitrary amount regardless of the length of the jack cord 3 pulled out. For example, when the mobile phone is put in another pocket of the jacket or used in a car during driving, the length of the jack cord 3 is changed as described above, but the earphone cords 4, 4 are not related to this. Can always be used by pulling the earphones 41, 41 in a length that is easy to attach to the ear.

  The mobile phone earphone / microphone device 1 is electrically connected to the mobile phone by turning on the connection switch 20, and a sound signal is transmitted from the mobile phone via the jack cord 3, the device body 2, and the earphone cords 4, 4. The earphones 41 and 41 can hear the voice of the other party and the music distributed from the mobile phone at a volume adjusted by the volume body 22. In addition, a voice or the like collected by the microphone 21 of the apparatus main body 2 is sent to the mobile phone side via the jack cord 3. At that time, since the apparatus main body 2 can be a portion close to the mouth such as a breast pocket of an outer jacket, the voice is clearly transmitted to the telephone partner.
