Problems solved by technology

The keyboard area of ​​a miniature mobile terminal is usually small, and the layout of the keys is compact. The shape design of the keys of some types of mobile terminals is not conducive to accurate pressing, and the error rate is high during operation, especially for special groups (the elderly, visually impaired, etc.) cause a lot of inconvenience
It is also inconvenient for the user to hold the mobile terminal to operate the keyboard while wearing the earphone cable, and most people have to use the hand on the opposite side of the earphone cable to operate the keyboard of the mobile terminal

Embodiment Construction

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0010] figure 1 is a view showing the appearance of the headphone cord according to the embodiment of the present invention.

[0011] refer to figure 1 , according to an embodiment of the present invention, a dial control keyboard area can be set on the earphone line, and a section of touch pressure sensing area can be set as the keyboard number 0-9 dial area at the same time, and the area control switch (not shown) can be set at the control button. When the zone control switch is turned off, the headset is in a normal functional state. When the area control switch is turned on, the earphone cable can transmit the button control signal to the mobile terminal to realize the simple keyboard function, so that simple dialing and other control functions can be completed without manipulating the keyboard of the mobile terminal. If you find that you have pressed ...

Abstract

The invention provides a contact type earphone wire supporting the keypad function and including a contact induction region, which includes: a plurality of resistors, having different resistance values; a plurality of elastic contact switches respectively connected with the resistors, and the position of the elastic contact switches being corresponding to the keys of the contact induction region; a loop signal wire connected with a plug with the contact type earphone wire, and the resistors being connected in parallel by the loop signal wire, so that each resistor, each elastic contact switch and the loop signal wire form a plurality loops independent with each other, respectively corresponding to different key functions. The contact type earphone wire has convenient operation, a user can finish the operations of dialing without handling a mobile terminal.

Description

technical field [0001] The present invention relates to an earphone cord used for a mobile terminal, more specifically, the present invention relates to a touch-press earphone cord supporting a keyboard function. Background technique [0002] The keyboard operation of the existing mobile terminal is completed by the keyboard on the fuselage or by voice. The technology and production cost of voice operation are relatively high, and it is easy to be interfered, and the recognition accuracy is unstable. The keyboard area of ​​a miniature mobile terminal is usually small, and the layout of the keys is compact. The shape design of the keys of some types of mobile terminals is not conducive to accurate pressing, and the error rate is high during operation, especially for special groups (the elderly, visually impaired, etc.) cause a lot of inconvenience. It is also inconvenient for the user to hold the mobile terminal to operate the keyboard while wearing the earphone cable, and m...
