State the concrete meaning of term in this application.
In a kind of embodiment provided by the present application, bluetooth headset obtains data from mobile phone or other audio-sources, after decoding
It plays out.Due to being the mode being wirelessly connected between mobile phone and bluetooth headset, mobile phone is needed the digital audio-frequency data of broadcasting
Be overpressurized and bluetooth headset be then sent to by Bluetooth signal, bluetooth headset receive the digital audio-frequency data after the pressurization it
Afterwards, it carries out corresponding decompression and obtains digital audio-frequency data to be played.Bluetooth headset plays out the digital audio-frequency data,
It needs the audio data obtaining the corresponding analog audio signal of digital signal by D/A conversion equipment, finally by amplifier
Driving loudspeaker plays out after amplifying to analog audio signal, however for the audio-frequence player device of some professions,
What it was transmitted is lossless analog audio signal.
Again since in order to enable bluetooth headset is more portable, so that its volume becomes small, smaller volume is just meaned
For placing battery space it is just smaller, and then cause bluetooth headset continuation of the journey insufficient, it is difficult to meet and bluetooth headset is commonly used
User demand.
In the user group of high-end profession, user, which is not only satisfied with, enough plays music by bluetooth headset.Especially
Some earphone enthusiasts not only pursue high-level sound quality, also pursue different music styles.However current bluetooth headset is once
After factory, the style of the music played is also just fixed up accordingly, to experience different tone sense effects, can only replace
New bluetooth headset.
In view of this, the embodiment of the present application provides a kind of multi-functional input interface, it is applied to bluetooth headset, this is multi-functional defeated
Incoming interface includes that the first analogue audio frequency contact, the first power supply contact and the first program upgrade contact.Fig. 1 is please referred to, Fig. 1 is that this is more
The connection structure diagram schematic diagram of the contact of function input interface 110 and the bluetooth headset 100.Wherein, the first analogue audio frequency contact
1101 connect with the analog audio input circuit of the bluetooth headset 100, the power supply of the first power supply contact 1102 and bluetooth headset 100
Circuit connection, the first program upgrades contact 1103 and the program of the bluetooth headset 100 upgrades circuit connection.
Optionally, balance simulation output is the analogue audio frequency connection type of current relative ideal, since balanced line is a kind of
The optimal audio signal wire of laser propagation effect, transmission is analog audio signal, but former with common tone frequency channel wire construction and transmission
Reason is different, and every, ordinary audio line is all single wire transmission signal, and shielded layer doubles as ground wire；Balanced line is then that two conducting wires pass
Defeated signal, in addition a core is independent makees ground wire, and realization separately works with shielded layer, transmission loss can be made to be preferably minimized in this way,
And external various interference can be effectively eliminated, to achieve the purpose that high-fidelity transfer audio signal, so a large amount of profession sound
Frequency playback equipment is all to export audio by balance simulation.
Referring to figure 2., Fig. 2 is the contact junction composition of the multi-functional input interface 110, which is patterned into the present embodiment
A kind of local structural graph of the pcb board of the bluetooth headset 100 provided, the contact of the multi-functional input interface 110 is uniformly distributed in
The two sides of the PCB.It is worth noting that the unlimited knot provided in this embodiment of the physical form of the multi-functional input interface 110
Composition, as long as the multi-functional input interface 110 can provide function disclosed in the embodiment of the present application.
In a kind of embodiment provided by the present application, the analogue audio frequency of professional audio playback equipment first can be passed through into profession
A/D (analog to digital converte, analog signal/digital signal converter) conversion chip obtain corresponding number
Signal is sent to bluetooth headset 100 by Bluetooth signal and plays out.However, no matter the conversion accuracy of A/D conversion chip how
It is promoted, compared to primary analogue audio frequency, still has the loss of data.In order to enable 100 user of bluetooth headset can experience
Lossless analogue audio frequency, the embodiment of the present application provide the first analog audio of the analog audio signal exported for receiving balance line
Frequency contact 1101, the first analogue audio frequency contact 1101 include L channel cathode contact 1201, L channel cathode contact 1207, the right side
