The circuit unit 5 converts an electric signal, which is an audio signal, into a driving signal.

A dedicated application program is installed in the portable terminal 1 and an audio signal of various patterns predetermined in accordance with the operation of the dedicated application program is generated and an audio signal as an electric signal is supplied to the circuit unit 5 by the ear plug 6, Lt; / RTI >

Specifically, different audio signals are transmitted to the circuit unit 5 through the first signal unit 62 and the second signal unit 63, respectively.

The circuit unit 5 converts the audio signal into a drive signal for operating the drive module 4 and applies a current to the coil 43. [

Accordingly, the first driving unit is operated by the electric signal transmitted through the first signal unit 62, and the second driving unit is operated by the electric signal transmitted through the second signal unit 63.

When an electric current is applied to the coil 43, the electromagnetic force is generated by an electromagnetic interaction with a magnetic field formed by the magnet 42, and the electromagnetic force moves the coil 43 along the center yoke 413.

At this time, since the coil 43 is mounted on one end of the rotator 44, the rotator 44 rotates the drive shaft 441 while rotating around the drive shaft 441 together with the coil 43.

That is, the coil 43, the rotator 44, and the drive shaft 441 rotate together.

At the same time, the spring 46 coupled to the other end of the rotator 44 is bent and elastically deformed.

As a result, the operating part 3 connected to the driving shaft 441 is rotated, and the ears (operating parts 3a and 3b) of the fixing part 2 made of the dog character are lifted up as shown in FIG.

When the current is interrupted in the coil 43, the electromagnetic force disappears and the coil 43, the rotator 44 and the drive shaft 441 rotate in the opposite direction due to the elastic restoring force of the spring 46, 3b) descend and return to the home position.

The operation unit 3 as described above can express various patterns of operation predetermined according to the audio signal by the dedicated application program and can operate the user by operating the portable terminal 1. [

When the earphone plug 6 for transmitting an electric signal to the circuit unit 5 is inserted into the voice output terminal and the voice communication is performed using the portable terminal 1, The voice signal is output to the front speaker of the portable terminal 1 without being transmitted to the ear plug 6 through the voice output terminal.

Therefore, it is possible to communicate without separating the portable terminal 1 and the accessories.

Hereinafter, a driving module for a portable terminal accessory according to an embodiment of the present invention will be described in more detail.

FIG. 9 is an exploded perspective view of the driving module according to the embodiment of the present invention, FIG. 10 is a sectional view taken along line A-A of FIG. 7, and FIG. 11 is a sectional view taken along line B-B of FIG.

The circuit unit 5 converts an audio signal into a driving signal to apply a current to the coil 43 in order to operate the driving module 4.

When an electric current is applied to the coil 43, the electromagnetic force is generated by an electromagnetic interaction with a magnetic field formed by the magnet 42, and the electromagnetic force moves the coil 43 along the center yoke 413.

At this time, since the coil 43 is mounted on one end of the rotator 44, the rotator 44 rotates the drive shaft 441 while rotating around the drive shaft 441 together with the coil 43.

That is, the coil 43, the rotator 44, and the drive shaft 441 rotate together.

At the same time, the spring 46 coupled to the other end of the rotator 44 is bent and elastically deformed.

As a result, the operating portion 3 connected to the driving shaft 441 is rotated, and the ear (operating portion 3) of the fixing portion 2 made of the puppy character is lifted up as shown in FIG.

When the current is interrupted in the coil 43, the electromagnetic force disappears and the coil 43, the rotator 44 and the drive shaft 441 rotate in the opposite direction due to the elastic restoring force of the spring 46, And then returns to the home position.

The operation unit 3 as described above can express various patterns of operation predetermined according to the audio signal by the dedicated application program and can operate the user by operating the portable terminal 1. [

Such an accessory can be carried along with the portable terminal 1, and can perform a variety of interesting games by performing actual operations in conjunction with a dedicated application program.

The ear plug of the accessory for the portable terminal of the present invention, the accessory provided with the ear plug and the driving module for the portable terminal accessory are not limited to the above-described embodiments, and various modifications may be made within the scope of the technical idea of the present invention .
