Abstract
The utility model discloses a headphone plug special for Apple products. The plug comprises a plug body, a connection body connected with the plug body and a control circuit, wherein the forefront end of the plug body (1) is a half-metal half-insulator structure, the control circuit comprises an MOS tube, a first resistor and a second resistor; the external level control signal is input to a grid electrode of the MOS tube by the first resistor, a drain electrode of the MOS tube is connected with one end of the connection body (2), and a source electrode of the MOS tube is ground by the second resistor. Peripheral devices are controlled to realize the free switch control of a terminal audio input/output signal transmission channel of the Apple products such as iPhone/iPad/iPod.
Description
Technical field
The utility model 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 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, wish the normal operation of its boombox and microphone.
The utility model content
The utility model provides a kind of headset plug, solves 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 guarantee the normal operation of its boombox and microphone, thereby realized free switching controls to apple terminal audio frequency input/output signal transmission channels such as apple iPhone/iPad/iPod by controlling ancillary equipment.
The utility model 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 is by the second grounding through resistance.
As the further prioritization scheme of a kind of apple terminal-specific of the utility model 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 utility model headset plug, the material of the insulator structure of described plug body is plastic cement.
The utility model 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 utility model.Number in the figure: 1-plug body, the connector of 2-plug body.
Fig. 2 is use status circuit figure of the present utility model.
Fig. 3 is use schematic diagram of the present utility model.
Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model 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 is partly insulator, and the C indication is partly metallic object).When the apple terminal 3.5mm audio sockets such as headset plug insertion apple iPhone/iPad/iPod, 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, a termination metal-oxide-semiconductor drain electrode 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, make the apple terminal 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 is by the second grounding through resistance.
2. a kind of apple terminal-specific headset plug as claimed in claim 1, it is characterized in that: the material of the metallic object structure of described plug body is copper.
3. a kind of apple terminal-specific headset plug as claimed in claim 1 or 2, it is characterized in that: the material of the insulator structure of described plug body is plastic cement.
