Hereinafter, with reference to the accompanying drawings a preferred embodiment of a removable mobile phone according to the present invention will be described.

1 is a perspective view of a mobile phone detachable accessory according to the present invention.

As shown in Figure 1, a variety of electrical components are built-in and the body 10, the antenna is installed at one upper end, and the hinge is coupled to both sides of the lower side of the body by a key (not shown) by opening and closing of the user A cover 20 capable of opening the display, a display unit 30 for displaying a telephone number input and an operation state by pressing the key, and a detachable form on the underside of the body of the mobile phone, It is composed of an external accessory 40 having a stereo speaker, a headphone function, an ear jack function, a speakerphone function, a vibration function, a radio function, and an external power input function inside.

As shown in FIG. 2, the external accessory 40 is detachably connected to an external power supply unit 40-1 that receives operating power from a battery pack and switches to an external mode, and is detachably connected to the bottom of the body of the mobile phone. A connector 40-2, a codec 40-3 connected to the connector 40-2 to perform encoding / decoding of a signal, a stereo speaker function, a headphone function, an ear jack function, a speakerphone function Stereo and amplifier unit 40-4 to perform, the radio (40-5) that is turned on / off when the user selects the radio function, the mobile phone (on) or when receiving a signal from the other party to notify the user by vibration Is composed of a vibration unit (40-6).

3A is a circuit diagram of the power supply unit of FIG. 2, FIG. 3B is a circuit diagram of the codec of FIG. 2, FIG. 3C is a circuit diagram of the amplifier of FIG. 2, FIG. 3D is a circuit diagram of the radio of FIG. 2, and FIG. 3E is of FIG. 2. It is a circuit diagram of a vibration part.

Referring to the operation of the removable mobile phone is configured as described above is as follows.

First, during a call, the external accessory 40 can be attached to and detached from the underside of the body of the mobile phone.

If the user requests a function other than a call, when the external accessory 40, which is separately provided, is coupled to the bottom of the body of the mobile phone, the external power supply 40-1 receives power from a battery pack (not shown). A component mounted on accessory 40 provides an enable signal to allow the user to switch to an external mode.
