Abstract
The invention discloses a headset plug special for Apple terminals. The headset plug comprises a plug body, a connecting body connected with the plug body and a control circuit, wherein the most front end of the plug body (1) is in a semi-metal semi-insulator structure, and the control circuit comprises a metal oxide semiconductor (MOS) tube, a first resistor and a second resistor. External level control signals are input to grids of the MOS tube through the first resistor, a drain electrode of the MOS tube is connected with one end of the connecting body (2), and a source electrode of the MOS tube is grounded through the second resistor. Through control of peripheral equipment, free switching control of audio input/output signal transmission channels of the Apple terminals like iPhones, iPads and iPods is achieved.
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 employed headset plugs of apple terminal peripheral hardware such as existing apple iPhone/iPad/iPod are when inserting, and the apple terminals such as apple iPhone/iPad/iPod can automatic I/O with audio signal switch to headset plug.At this moment, its built-in loud speaker and microphone can't be worked.But in a lot of situations, ancillary equipment only just need to switch to headset plug with the I/O of audio signal 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 the normal operation of its boombox and microphone.
Summary of the invention
The invention provides a kind of headset plug, solve the problem that ancillary equipment is freely controlled the apple terminal audio frequency input/output signal switchings such as apple iPhone/iPad/iPod.Realized in the situation that guarantees the normal operation of its boombox and microphone, thereby by the free switching controls of control ancillary equipment realization 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 that adopts is:
A kind of apple terminal-specific headset plug comprises plug body, the connector that is 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, outside level controling signal inputs to the grid of metal-oxide-semiconductor by the first resistance, and described metal-oxide-semiconductor drain electrode is connected with an end of connector, and the source electrode of described metal-oxide-semiconductor passes through the second grounding through resistance; When metal-oxide-semiconductor grid input high level, the drain electrode of metal-oxide-semiconductor and source electrode conducting, the metallic object partial earthing of plug body front end, exterior terminal switches to headset plug with the audio frequency input/output signal; Otherwise, when metal-oxide-semiconductor grid input low level, the leakage level of metal-oxide-semiconductor and source electrode cut-off, exterior terminal automatically switches to boombox and microphone with the audio frequency input/output signal.。
As the further prioritization scheme of a kind of apple terminal-specific of the present invention 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 terminal-specific of the present invention 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 that ancillary equipment is to the free switching controls of the apple terminal audio frequency input/output signal transmission channels such as apple iPhone/iPad/iPod.
Description of drawings
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 use status circuit figure 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 elaborated.
As shown in Figure 1, headset plug is four-part form, mainly be divided into plug body 1 and the connector 2 that is 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 (the A indication partly is metallic object, and the B indication partly is insulator, and the C indication partly is metallic object).When inserting the apple terminal 3.5mm audio socket such as apple iPhone/iPad/iPod when headset plug, use the ancillary equipment of this headset plug can freely control as required the transmission channel of the apple terminal audio frequency input/output signals such as apple iPhone/iPad/iPod.
As shown in Figure 2, the drain electrode of a termination metal-oxide-semiconductor of the connector that the headset plug body connects, control signal connects the metal-oxide-semiconductor grid, and the metal-oxide-semiconductor source electrode passes through grounding through resistance; Metal-oxide-semiconductor grid input high level hourglass level and source electrode conducting in circuit shown in Figure 2, headset plug A holds ground connection, i.e. A and C conducting, the apple terminal switches to headset plug with the audio frequency input/output signal.At this moment, ancillary equipment can communicate by apple terminals such as MIC circuit and apple iPhone/iPad/iPod, and boombox and the microphone of the apple terminals such as apple iPhone/iPad/iPod can't be worked.Otherwise, during metal-oxide-semiconductor grid input low level, leak level and source electrode cut-off, the apple terminals such as apple iPhone/iPad/iPod automatically switch to boombox and microphone with the audio frequency input/output signal.
As shown in Figure 3, headset plug is when inserting the apple terminal, plug body 1 metal part foremost only allows towards volume button one side, be about to metallic object part (A end) ground connection of headset plug, the insulator part (B end) of headset plug cuts off boombox and microphone can't be worked it.When input high level, so that the apple terminal is by MIC circuit and original MIC connection; During input low level, the audio frequency input/output signal automatically switches to boombox and microphone.
Claims (3)
1. 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, described control circuit comprises metal-oxide-semiconductor and first, second resistance; Wherein, outside level controling signal inputs to the grid of metal-oxide-semiconductor by the first resistance, and described metal-oxide-semiconductor drain electrode is connected with an end of connector (2), and the source electrode of described metal-oxide-semiconductor passes through the second grounding through resistance; When metal-oxide-semiconductor grid input high level, the drain electrode of metal-oxide-semiconductor and source electrode conducting, the metallic object partial earthing of plug body front end, exterior terminal switches to headset plug with the audio frequency input/output signal; Otherwise, when metal-oxide-semiconductor grid input low level, the leakage level of metal-oxide-semiconductor and source electrode cut-off, exterior terminal automatically switches to boombox and microphone with the audio frequency input/output signal.
