Headset plug applicable for different system specifications

Abstract

The invention relates to a headset plug applicable for different system specifications, comprising a terminal and a switching device, wherein the headset plug is a plurality of signal interfaces exposed through the terminal so as to be inserted into a socket of an peripheral electronic device, while the switching device is combined at the terminal and the switching device is provided with a first conductive member and a second conductive member; when the switching device switches between a first mode and a second mode, the first conductive member and the second conductive member contact with two of the plurality of signal interfaces alternately, such that transmission signals defined by the plurality of signal interfaces can be changed to be applicable for electronic devices of different system specifications.

Description

technical field [0001] The invention relates to an earphone plug, in particular to an earphone plug which utilizes mechanical components to alternately switch the plug signal interface so as to comply with two system specifications of OMTP and AT&T. Background technique [0002] Headphones are one of the indispensable accessories for portable electronic products (such as mobile phones, MP3 players, PDAs, etc.), and their structure includes a headphone plug for receiving electronic signals, and for converting electronic signals into sound waves signal from the speaker. In recent years, with the rapid popularization of mobile phones, earphones must be combined with a microphone to provide users with a hands-free function for using mobile phones to achieve the purpose of safety and convenience in calls. At present, the most common headphone plugs can be divided into three-section and four-section types. The three-section type is mainly used for mono headphones, and the four-se...

Problems solved by technology

[0004] However, in addition to the above-mentioned OMTP system, there is another configuration method for the multiple signal interfaces A1, A2, A3 and A4 of the earphone plug at present, that is, the signal interface A1 transmits the left channel signal, and the signal interface A2 transmits the right channel signal , signal interface A3 transmits the ground signal, signal interface A4 transmits the microphone signal, this configuration belongs to the AT&T system

[0005] The above two system configurations still commonly exist in the headphone socket and headphone plug of many mobile phones, so if consumers take the headphone plug of the OMTP system and want to insert it into the headphone socket of the AT&T system, some sounds will be cut off. That is, the functions cannot be fully displayed. Therefore, for users, the most guaranteed thing is to use the earphones provided by the mobile phone manufacturer when purchasing a mobile phone. However, in fact, users certainly hope that their earphones can be used in different It can be applied to different system specifications, no matter the headphone plug is inserted into the headphone socket of any mobile phone, it can effectively perform functions such as music transmission and voice transmission

[0006] This shows that above-mentioned existing earphone plug obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to meet users' needs for a single accessory that can be applied to multiple products, relevant manufacturers have tried their best to find a solution, but for a long time no applicable design has been developed, and general products have not been suitable. The cutting structure can solve the above problems, which is obviously a problem that the relevant industry is eager to solve
