Specific embodiment
In being described below, in order to illustrate rather than in order to limit, it is proposed that such as tool of particular system structure, technology etc Body details, to understand thoroughly the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specifically The present invention can also be realized in the other embodiments of details.In other situations, omit to well-known system, device, electricity Road and the detailed description of method, in case unnecessary details interferes description of the invention.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
As shown in Figure 1, the bluetooth headset of the embodiment of the present invention is shown in figure, including the first contact, the second contact, the 3rd Contact, direct current partition module, bluetooth module, controllable switch, power supply and loud speaker, wherein:
First contact is connected with the energization pins of bluetooth module, and the first contact separates module and loud speaker by direct current Audio input pin be connected, the controlling switch of controllable switch is connected with bluetooth module;
Second contact is connected with the input and output pin of bluetooth module, and the signal output pin of bluetooth module is by controllably opening Pass is connected with the audio input pin of loud speaker;
3rd contact is connected with the grounding pin of loud speaker.
First contact, the second contact and the 3rd contact can collect time arrangement, correspondingly, suitable according to the arrangement of bluetooth headset Sequence, corresponding control conversion earphone socket, the setting order of charging earphone socket.For example, bluetooth headset is according to the first contact, Two contacts, the 3rd contact order set when, then convert earphone socket then successively correspondingly set the 4th contact, the 5th contact, 6th contact, charging earphone socket then set gradually the 7th contact, the 8th contact, the 9th contact.
As shown in Fig. 2, showing the structure of conversion earphone socket in figure, conversion earphone socket includes the 4th contact, the 5th Contact and the 6th contact, the 4th contact are connected with Audio Data Line, and the 5th contact passes through pull-up resistor and conversion earphone socket Power supply is connected, and the 6th contact is connected with converting the ground wire of earphone socket.
As shown in figure 3, showing the connection of charging earphone socket and bluetooth headset in figure, charging earphone socket includes the 7th Contact, the 8th contact and the 9th contact, the 7th contact are connected with the power supply of charging earphone socket, and the 9th contact is inserted with charging earphone The ground wire of seat is connected, and the 8th contact is hanging or is connected with serial communication interface.
Serial communication interface can be UART interface, can be to bluetooth module by by the second contact portion UART interface It carries out the operation such as debugging.
Direct current partition module is used for the voltage for separating direct current, so that the first contact and the socket power of charging earphone socket When being connected, separate the socket power of charging earphone socket, loud speaker will not be caused noise occur or influence making for bluetooth headset Use the service life.
Preferably, direct current partition module includes passive blocking module and/or passive bandpass filters, to improve bluetooth headset Export the quality of audio.As shown in Figure 1, direct current partition module includes passive blocking module and passive bandpass filters, pass through nothing Source blocking module can filter out the influence of DC power supply, by passive bandpass filters, can filter out its beyond audio signal The influence of its noise.
Bluetooth module includes dormant state and working condition, when bluetooth headset is wireless use state, at bluetooth module In working condition, when bluetooth headset is wired use state, bluetooth headset may be at dormant state.
Can by the detection of the contact voltage of the second contact come judge bluetooth module whether in wired use state or Wireless use state.For example, whether the voltage that the second contact can be detected is judged more than certain voltage value.When the second contact Voltage be more than certain voltage value when, bluetooth headset be in wired broadcast state, by bluetooth module control controllable switch connection, Bluetooth module works normally, and receives audio signal by bluetooth module, is sent to loud speaker via controllable switch and plays out.
Controllable switch, that is, active low-ohmic switches, the controlling switch of controllable switch are connected with bluetooth module, can pass through indigo plant Tooth module controls the opening and closing of controllable switch.
Power supply can be rechargeable battery, such as rechargeable lithium battery etc..
Loud speaker is loud speaker built-in in bluetooth headset, and the size of the sound of loud speaker can pass through bluetooth module phase The adjustment answered can also be adjusted by the main side equipment being connected with bluetooth headset.
When bluetooth headset is connected with charging earphone socket as shown in Figure 3, bluetooth module controls active low-ohmic switches to break It opens, the connection between direct current partition module partition loud speaker and the socket power of the first contact, so that charging current will not Trumpet end is influenced, electric current has been avoided to enter loudspeaker, sends noise.Second contact is hanging or is serial communication interface, can use It is used in carrying out debugging to bluetooth module.
As shown in figure 4, the bluetooth headset provided in an embodiment of the present invention based on bluetooth headset and conversion earphone socket is with having The method of line earphone conversion, including:
In step S401, when detecting that the second contact of bluetooth headset is connected with converting the 5th contact of earphone socket, Controllable switch is controlled as off-state and closes bluetooth module.
In embodiments of the present invention, when the socket of the second contact portion to the conversion earphone socket that detect bluetooth headset is electric During source, controllable switch is controlled so that bluetooth headset closes radio play state, and to close bluetooth module for off-state, It can so that bluetooth headset is more energy saving.
It specifically, the 5th contact being connected with the second contact can be by way of pull-up resistor with converting earphone socket Power supply is connected.
Preferably, the first voltage value of the second contact is detected, when the first voltage value is more than default voltage value, control can Control switch is off-state and closes bluetooth module, so that bluetooth headset is more energy saving.It is further preferred that detection second is touched The first voltage value of point, when the ratio of the first voltage value and the voltage value of bluetooth headset is more than predetermined threshold value, for example, when first When the ratio of the voltage value of voltage value and bluetooth headset is more than 2, controllable switch is controlled as off-state and closes bluetooth module, from And the unlatching of bluetooth headset is further accurately controlled, improve the utilization ratio of bluetooth headset.
Herein, which is less than the voltage of the 4th contact, so as to accurately and effectively judge to convert ear Whether machine transplanting of rice seat is connected with bluetooth headset.In addition, predetermined threshold value can flexibly be set according to the use habit of user, when multiple is got over Greatly, then can be longer by the duration for the state that bluetooth headset is in radio play, consume the electricity of power supply in more bluetooth headsets.
In step S402, voice data is sent to loud speaker by the first contact and played out by the 4th contact;
In embodiments of the present invention, the first contact can separate mould passive blocking module in the block and passive band by direct current Audio signal is sent in loud speaker by bandpass filter, to improve the quality of output audio.
In step S403, the 3rd contact is connected with the ground wire of the 6th contact.
