Earphone hole type holding wire

Abstract

This invention discloses an earphone hole signal line, which designs a first connector and a second connector at both ends of a signal line, in which, said first connector is used in plugging in an earphone hole of a mobile phone and the second connector is used in plugging in a hand-free earphone, said signal line includes at least an earphone circuit and a microphone circuit, the earphone hole signal line is set with an incoming test unit for triggering operation of the hand-free earphone.

Description

technical field [0001] The invention relates to an earphone hole type signal line, in particular to a signal line which can be plugged between the earphone hole of a mobile phone and a hands-free handset, so as to effectively increase the versatility of the signal line and reduce the manufacturing cost. Background technique [0002] The structure of the current general-purpose hands-free handset is as follows: figure 1 As shown, a single hands-free handset 1 is combined with a signal line 2. One end of the signal line 2 is provided with a joint 21 to connect to the hands-free handset 1, and the other end is provided with a joint 22 corresponding to the level jack of the mobile phone. When the user changes the mobile phone, the use of the original speakerphone can be retained by changing the signal line 2 corresponding to the style of the newly purchased mobile phone. [0003] The above-mentioned known general-purpose hands-free handset uses the method of replacing the signa...

Problems solved by technology

[0003] The above-mentioned known general-purpose hands-free handset uses the method of replacing the signal line to solve the problem that the hands-free handset cannot be used universally. In the past, the signal line of the hands-free handset was used. It can be obtained through the special connector of the line, which includes functions such as sound signal and incoming call notification signal. Although mobile phones of the same brand may share a small number of signal lines, most of them still need a signal line to match a mobile phone. However, due to the There are many types of mobile phones, and the replacement rate is fast. If the traditional method of developing signal lines is followed, there will be the following defects:

[0004] 1. Mobile phones are launched too quickly and have a short lifespan in the market. In the past, the development of signal lines for special connectors was difficult and took a long time. Often, after the development of a new signal line is completed, the corresponding mobile phone has already withdrawn from the market. As a result, consumers cannot quickly enjoy the convenience of continuing to use the hands-free handset in the car when replacing a new mobile phone, resulting in a waste of the hands-free handset for the car

[0005] 2. There are many types of mobile phones, so many kinds of signal lines with special connectors need to be developed to meet the market demand. In this way, in addition to the increase in manufacturer development and inventory costs, signal line vendors also need to prepare many types. Signal lines to cope with the various types of mobile phones in the market; in addition, if the prepared signal lines and their corresponding mobile phones have withdrawn from the market, these signal lines will be useless and will cause great losses
