Abstract
The invention discloses a kind of apple terminal-specific headset plug, this plug comprises plug body, the connector be connected with plug body, control circuit, described plug body (1) be semimetal semi-insulator structure foremost, described control circuit comprises metal-oxide-semiconductor and first, second resistance; Wherein, external level control signal inputs to the grid of metal-oxide-semiconductor by the first resistance, and described metal-oxide-semiconductor drain electrode is connected with one end of connector (2), and the source electrode of described metal-oxide-semiconductor is by the second grounding through resistance.The present invention is by controlling ancillary equipment thus realizing the free switching controls to apple terminal audio frequency input/output signal transmission channels such as apple iPhone/iPad/iPod.
Description
Technical field
The present invention relates to a kind of headset plug, particularly a kind of headset plug of apple terminal-specific.
Background technology
The headset plug that the apple terminal peripheral hardwares such as existing apple iPhone/iPad/iPod use is when inserting, and the I/O of audio signal can be switched to headset plug by the apple terminals such as apple iPhone/iPad/iPod automatically.Now, its built-in loud speaker and microphone cannot work.But in a lot of situation, ancillary equipment only just needs the I/O of audio signal to be switched to headset plug when carrying out data communication with the apple terminal such as apple iPhone/iPad/iPod by external Mike's circuit.In other situation, then wish that its boombox and microphone normally work.
Summary of the invention
The invention provides a kind of headset plug, solve the problem that ancillary equipment freely controls the apple terminal audio frequency input/output signal switchings such as apple iPhone/iPad/iPod.Achieve when ensureing that its boombox and microphone normally work, by controlling ancillary equipment thus realizing the free switching controls to apple terminal audio frequency input/output signal transmission channels such as apple iPhone/iPad/iPod.
The present invention is for solving above technical problem, and the technical scheme adopted is:
A kind of apple terminal-specific headset plug, comprises plug body, the connector be connected with plug body, control circuit, described plug body be semimetal semi-insulator structure foremost, described control circuit comprises metal-oxide-semiconductor and first, second resistance; Wherein, external level control signal inputs to the grid of metal-oxide-semiconductor by the first resistance, and described metal-oxide-semiconductor drain electrode is connected with one end of connector, and the source electrode of described metal-oxide-semiconductor is by the second grounding through resistance; When metal-oxide-semiconductor grid input high level, the drain electrode of metal-oxide-semiconductor and source conduction, the metallic object partial earthing of plug body front end, audio frequency input/output signal is switched to headset plug by exterior terminal; Otherwise when metal-oxide-semiconductor grid input low level, the leakage level of metal-oxide-semiconductor and source electrode end, and audio frequency input/output signal is automatically switched to boombox and microphone by exterior terminal.。
As the further prioritization scheme of a kind of apple of the present invention terminal-specific headset plug, the material of the metallic object structure of described plug body is copper.
As the further prioritization scheme of a kind of apple of the present invention terminal-specific headset plug, the material of the insulator structure of described plug body is plastic cement.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
Realize the free switching controls of ancillary equipment to apple terminal audio frequency input/output signal transmission channels such as apple iPhone/iPad/iPod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.Number in the figure: 1-plug body, the connector of 2-plug body.
Fig. 2 is using state circuit diagram of the present invention.
Fig. 3 is use schematic diagram of the present invention.
Embodiment
Below with reference to accompanying drawing, technical scheme of the present invention is described in detail.
As shown in Figure 1, headset plug is four-part form, the connector 2 being mainly divided into plug body 1 and being connected with plug body, plug body 1 is semimetal semi-insulator structure, the part that oblique line shown in Fig. 1 covers is insulator structure, remainder is metallic object mechanism (A indication part is metallic object, and B indication part is insulator, and C indication part is metallic object).When inserting the apple terminal 3.5mm audio sockets such as apple iPhone/iPad/iPod when headset plug, use the ancillary equipment of this headset plug freely can control the transmission channel of the apple terminal audio frequency input/output signals such as apple iPhone/iPad/iPod as required.
As shown in Figure 2, a termination metal-oxide-semiconductor drain electrode of the connector that headset plug body connects, control signal connects metal-oxide-semiconductor grid, and metal-oxide-semiconductor source electrode passes through grounding through resistance; When metal-oxide-semiconductor grid input high level hourglass level and source conduction in circuit shown in Fig. 2, headset plug A holds ground connection, i.e. A and C conducting, and audio frequency input/output signal is switched to headset plug by apple terminal.Now, ancillary equipment communicates with apple terminals such as apple iPhone/iPad/iPod by MIC circuit, and boombox and the microphone of the apple terminals such as apple iPhone/iPad/iPod cannot work.Otherwise during metal-oxide-semiconductor grid input low level, leakage level and source electrode end, and audio frequency input/output signal is automatically switched to boombox and microphone by the apple terminals such as apple iPhone/iPad/iPod.
As shown in Figure 3, headset plug is when inserting apple terminal, plug body 1 metallic member foremost only allows towards volume button side, by metallic object part (A end) ground connection of headset plug, the insulator part (B end) of headset plug cuts off boombox and microphone makes it work.When input high level, make apple terminal by MIC circuit and original MIC connection; During input low level, audio frequency input/output signal automatically switches to boombox and microphone.
Claims (3)
1. an apple terminal-specific headset plug, the connector (2), the control circuit that comprise plug body (1), are connected with plug body, it is characterized in that: described plug body (1) foremost for semimetal semi-insulator structure, and metallic member is parallel with axis foremost with the divisional plane of insulator part; Described control circuit comprises metal-oxide-semiconductor and first, second resistance; Wherein, external level control signal inputs to the grid of MOS pipe by the first resistance, and described MOS pipe drain electrode is connected with one end of connector (2), and the source electrode of described MOS pipe is by the second grounding through resistance; When MOS tube grid input high level, the drain electrode of MOS pipe and source conduction, the metallic object partial earthing of plug body front end, audio frequency input/output signal is switched to headset plug by apple terminal; Otherwise when MOS tube grid input low level, the leakage level of MOS pipe and source electrode end, audio frequency input/output signal is automatically switched to boombox and the microphone of apple terminal by apple terminal.
