[0006] In the earphone connection mechanism with a remote controller configured as described above, a slide switch (not shown) for switching the control operation is slid in the operation direction of the remote control to turn on the switch and to switch on the earphone unit 4. By connecting the connector plug 10 to a connector socket (not shown), a remote control operation can be performed.

In order to use a normal earphone (earphone without a remote controller), a slide switch (not shown) for switching the control operation is slid in a direction opposite to the operation direction of the remote control to turn off the switch. At the same time, it can be performed by connecting a connector plug (not shown) of an earphone unit (not shown) to a connector socket (not shown).

[0008]

By the way, in a conventional connection mechanism of an earphone with a remote controller,
Using a slide switch (not shown) for control operation switching from a control operable state when using an earphone without a remote controller to a remote control operable state when using an earphone with a remote controller or using an earphone with a remote controller Is changed from the remote control operable state to the control operable state when an earphone without a remote controller is used. Therefore, when the use of these earphones is changed, the connector plug 10 is inserted into a connector socket (not shown). An operation and a switching operation of a slide switch (not shown) were required. As a result, the number of operations when changing the use of the earphone without the remote controller and the earphone with the remote controller is increased, and there is a problem that the operation of changing the use of the earphone is complicated.

The present invention has been made in view of such circumstances, and the number of operations when changing the use of an earphone without a remote controller and an earphone with a remote controller can be reduced, thereby simplifying the operation of changing the use of the earphone. An object of the present invention is to provide a connection mechanism of an earphone with a remote controller that can be performed.

[0010]

A connection mechanism for an earphone with a remote controller according to the present invention includes an audio equipment main body having a connector socket for connecting a connector plug , a connector plug and a switch to be inserted into and extracted from the connector socket of the audio equipment main body. In a connection mechanism of an earphone with a remote controller including a pressing rod and an earphone unit having a remote controller connected to the connector plug, a switch for control operation switching is attached to the audio equipment main body, and the switch is inserted and removed by inserting and removing the connector plug. A switch pressing bar that opens and closes is provided in an earphone unit.

[0011]

According to the present invention, a control operable state when an earphone without a remote controller is used is changed from a control operable state when an earphone without a remote controller is used or a remote control operable state when an earphone with a remote controller is used only by an insertion / removal operation of a connector plug with respect to a connector socket. The remote control operable state when using the earphone can be changed to the control operable state when using the earphone without the remote controller.
