Embodiment 1

[0058] A mobile phone headset access device according to an embodiment of the present invention includes a headset jack 2, an audio encoding decoder 3, and a switch switching module. The audio encoding decoder 3 is used to encode and decode audio data, and the headset jack 2 is switched through The switching module is connected to the audio encoding decoder 3, the earphone socket 2 is used to connect the earphone plug 1, and the switch switching module is used to switch the connection mode when its connection mode does not conform to the interface standard of the inserted earphone plug 1 To a connection mode that conforms to the interface standard of the earphone plug 1; wherein the connection mode of the switch switch module conforms to the interface standard of the inserted earphone plug 1 means that the switch switch module is in this connection mode, and the earphone socket Each signal terminal of 2 is connected to the corresponding signal terminal of the audio coding decode...

Embodiment 2

[0081] Such as image 3 As shown, the 2.5mm mobile phone headset access device of an embodiment of the present invention, for a 2.5mm, 3-segment headset, its end is equivalent to the combination of the end of the 4-segment headset and the middle ring 2, so the 2.5mm mobile headset access In the device, when a 3-segment earphone is inserted, the interface 1 and signal terminal 2 of the earphone socket are connected to the end of the 3-segment earphone. Since the interface 1 is connected to the GND signal terminal of the audio encoding decoder, no matter how the SW2 is switched, the earphone The ends of the sockets are all GND.

[0082] If the mobile phone earphone access device is switched to the foreign interface standard, the analog switch SW1 connects the signal terminal 4 of the earphone socket and the MIC signal terminal, and the three-stage earphone socket is "MIC / R / GND" from the tip to the end, and the middle ring is single Channel R, the 3-segment headphone jack from the t...

Embodiment 3

[0086] Such as Figure 4 As shown, in a 3.5mm mobile phone earphone access device according to an embodiment of the present invention, the earphone socket 2 includes six signal terminals, the signal terminal 1 is connected to the earphone plug end, the signal terminal 2 is connected to the earphone plug middle ring 2, and the signal terminal 3 and The signal terminal 5 is connected with the earphone plug center ring 1, and the signal terminal 4 and the signal terminal 6 are connected with the tip of the earphone plug.

[0087] The audio coding decoder 3 has four signal terminals, namely L, R, GND and MIC signal terminals. Among them, the first signal terminal is MIC, and the second signal terminal is GND.

[0088] The baseband processor 4 includes an Ear_Det earphone detection signal terminal and a Channel_Ct1 channel control signal terminal.

[0089] The signal terminal 3 of the earphone socket 2 is connected to the R signal terminal of the audio encoding decoder 3, the signal term...

Abstract

The invention discloses a device for accessing an earphone of a mobile phone, comprising an earphone socket, an audio encoding and decoding device and a switch switching module, wherein the audio encoding and decoding device is used for encoding and decoding audio data; the earphone socket is connected with the audio encoding and decoding device by the switch switching module and is used for connecting an earphone plug; and the switch switching module is used for switching the connection mode into a connection mode conforming to the interface standard of the earphone plug when the connection mode of the switch switching module does not conform to the interface standard of the earphone plug. The device for accessing the earphone of the mobile phone can be compatible with earphones of the mobile phones with different interface standards.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a mobile phone headset access device and a mobile phone headset access method. Background technique [0002] At present, the universal mobile phone headphone jack is a concentric connector with a standard specification that follows the JIS C 6560-1994 standard, including a socket end and a plug end, and the mobile phone side uses a socket end. There are two kinds of interfaces for mobile phone headsets, which are called 2.5mm concentric connector interface and 3.5mm concentric connector interface according to the diameter of the connector. Hereinafter referred to as 2.5mm interface and 3.5mm interface, it can also be called 2.5mm mobile phone headset. And 3.5mm mobile phone headset. [0003] The above two headphone interface definitions mainly have two different typical standards: one is YD / T1885-2009 "Technical Requirements and Test Methods for Mobile Phone Headphone Interfaces of...
