Embodiment
To be connected with an earplug by tone frequency channel wire described Hybrid mode plate one end, the other end is connected in audio jack as embodiment is discussed in detail after being mixed with the tone frequency channel wire of another earplug by tone frequency channel wire.
Fig. 1 is the front view of multifunctional headphone of the present utility model; Fig. 2 is the rearview of multifunctional headphone of the present utility model; Fig. 3 is multifunctional headphone exploded front schematic diagram of the present utility model; Fig. 4 is multifunctional headphone exploded rear schematic diagram of the present utility model; Face and be as the criterion with Hybrid mode plate with backsight.As Figure 1-Figure 4, this multifunctional headphone comprises left and right earplug, connecting line, Hybrid mode plate and audio jack.Whole earphone is except Hybrid mode plate, and other is all similar to traditional wired earphone.Wherein, Hybrid mode plate is made up of two daughter boards, upper plate and lower plate, and two plates all have button and sound inlet, and upper plate has tone frequency channel wire (MIC, GND and HPL) to be connected to audio jack, and lower plate has tone frequency channel wire (GNDB and HPLB) to be connected to left earplug.
The upper plate of Hybrid mode plate is the line traffic control making sheet of conventional earphone, plate has microphone, line control machine, is all connected to MIC line, separately has a plug detecting module.Plate shell should have three buttons+, key C, key-, be connected to line control machine respectively, a sound inlet and a through hole, the inner corresponding microphone of sound inlet, the sound inlet of lead to the hole site then on another plate corresponding.The another side that plate shell and button oppose also has four contact pin electrodes (also can be other forms such as plane electrode), be connected to MIC respectively, GND, HPL and GNDa, a resistance Ra is connected between GND and plug detecting module, and GNDa is connected to plug detecting module (can be simple voltage comparator and pulses generation), after the plug state identification of four contact pins, detecting module drives the c that repeatedly pushes button, notice main frame.
Design key of the present utility model is the lower plate of Hybrid mode plate.The lower plate of Hybrid mode plate is bluetooth earphone mainboard, comprises bluetooth transceiver, audio process, power management and controller, microphone, battery, components and parts required for all bluetooth earphones such as USB interface are external earplug unlike its earplug, are driven by the audio frequency power amplifier in audio process.Plate shell should have a button Bc to be connected to internal controller, a sound inlet and a through hole, the inner corresponding microphone of same sound inlet, the sound inlet of lead to the hole site then on another plate corresponding.Plate shell and button Bc also have four jack electrodes (also can be other forms such as plane electrode) on the same face, corresponding with upper plate contact pin electrode, MICB respectively, GNDB, HPLB, CTRLB. this plate same needs plug detection short circuit, here with the simplest circuit realiration, resistance Rb is connected between VDD and CTRLB, like this when two plates interlock, forms bleeder circuit with Ra, if Rb > > is Ra, CTRLB=GNDa=GNDB, and when two plates are taken apart, CTRLB=VDD.Internal controller built-in voltage detection circuit monitoring CTRLB, then achieves and the most simply plugs detecting function.Note also having unlike, MICB line is connected to controller part, and controller can hardware or software simulation mode, and the line traffic control algorithm for different brands drives MICB, for the line traffic control data communication between main frame.MICB and HPLB line is connected to power management section, can built-in DC/DC (DC charging for MICB line) or AC/DC (AC charging for HPLB line) power module in controller, for main frame to the charging with bluetooth earphone.
Further, the four contact pins/jack of two plate inner faces (or more quantity, or other any mode, such as plane electrode is attracting with magnet), can realize machinery and be connected with electricity, dismantle very easily and fastening.
Further, can control to start the microphone on two plates simultaneously, realize multi-microphone recording, strengthen audio.Lower plate also can add sensor function, can in a wired fashion or wireless way for transmitting data with mobile phone.
Further, interface due to two plates is canonical form, can increase one or more intermediate plate therebetween, to increase any feature board of any adaptation and upper and lower plates interface, as long as its one side is contact pin another side is jack, the expansion of the function of Hybrid mode plate can be realized thus.
The job step that composition graphs 5 states multifunctional headphone of the present utility model is as follows:
When upper and lower two plates interlock, MIC=MICB, GND=GNDB, HPL=HPLB, GND=CTRLB, CTRLB are set to low level, are closed completely by bluetooth earphone.Upper and lower tone frequency channel wire is connected, and earphone can form a complete stereo wired line control earphone.Meanwhile, main frame also can by tone frequency channel wire MIC and or HPL charge to the battery of bluetooth earphone, such as main frame low-resistance high level direct current or DC/DC or the AC/DC module that exchanges in driving governor, for charging.Notice that frequency must be greater than audio frequency and people's ear be can't hear, and the impedance of earplug under this frequency greatly increases thus need not consume too many energy in earplug when main frame AC signal drives HPL line.
When upper and lower two plates interlock, but when audio jack does not insert main frame, the manually opened bluetooth earphone function of key Bc or the simple data transfer function use as anti-loss device can be pressed.
When upper and lower two plates interlock, audio jack inserts main frame, when realizing the call of wired earphone, when now taking two plates apart, the CTRLB of lower plate becomes high level from low level, bluetooth earphone starts automatically, after the plug of upper plate detects and do not overstate that identification two plate is taken apart, notice main frame, starts wireless blue tooth communication, converse with the bluetooth earphone of pairing, the hot drawing then realizing bluetooth earphone starts.
When upper and lower two plates interlock, audio jack inserts main frame, can manually press key Bc many times, carry out the microphone in notification audio processor startup lower plate, add the microphone on upper plate, two microphones can be had to work simultaneously, realize multi-microphone recording, strengthen audio, such as stereophonic recording, or background noise is eliminated, etc.
After upper and lower two plates are taken apart, electrode disconnects, and the CTRLB of lower plate is set to high level, opens whole bluetooth earphone, and occupation mode is the same with conventional Bluetooth earphone.But this bluetooth earphone is monophonic audio.
After upper and lower two plates are taken apart, electrode disconnects, upper plate, right earplug, and tone frequency channel wire and audio jack form the wired line control earphone of a complete monophony.Using method is the same with conventional earphone.
Another embodiment is connected with left and right earplug respectively for described Hybrid mode plate one end is separated two tone frequency channel wires, on the other end to be connected with audio jack by tone frequency channel wire, as shown in Figure 6 and Figure 7., be changed to: as the line traffic control making sheet of the conventional earphone of upper plate, one end is by tone frequency channel wire MIC, GND, and HPL, HPR are connected with audio jack; The other end is connected with an earplug by GND with HPR.Other all constant, comprise bluetooth earphone constant, implementation method, with reference to above-described embodiment, does not do detailed discussion at this.
Only as described above, be only preferred embodiment of the present utility model, such as professional who are familiar with this art.After understanding technological means of the present utility model, natural energy, according to actual needs, is changed under instruction of the present utility model.Therefore all equal changes of doing according to the utility model claim and modification, all should still belong in scope that the utility model patent contains.
