Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing pair
The utility model embodiment is described in further detail.
Embodiment one
As it is shown in figure 1, the utility model embodiment provides a kind of bluetooth earphone 100, comprising: voice touches
Send out module the 120th, audio frequency IC module the 150th, low-power consumption bluetooth module the 130th, conventional Bluetooth module the 140th,
Microphone 110 and loudspeaker 160.Wherein, low-power consumption bluetooth module 130 and host side 200 keep long
Connecting, low-power consumption bluetooth module 130 shuts down or low-power consumption bluetooth module 130 at bluetooth earphone 100
Being in sleep state before carrying out interactive voice with host side 200, conventional Bluetooth module 140 is at bluetooth ear
Machine 100 shuts down or is in and non-is in sleep state when taking phone.Voice activated module 120 and microphone
110th, low-power consumption bluetooth module 130 and conventional Bluetooth module 140 are electrically connected, audio frequency IC module
150 are electrically connected with loudspeaker the 160th, low-power consumption bluetooth module 130 and conventional Bluetooth module 140,
Low-power consumption bluetooth module 130 electrically connects with conventional Bluetooth module 140.Host side 200 can be for example hand
Machine or other intelligent wireless communication apparatus.
Wherein, microphone 110 is constantly in the state of monitoring users voice command, and the voice that will receive
Order is forwarded to voice activated module 120.
When user sends the voice command waking up low-power consumption bluetooth module 130 up, voice activated module 120
By this voice command with preset wake up keyword comparison up, if with default to wake up keyword up consistent, then language
Sound voice activated module 120 sends wake-up signal such as interrupt signal to low-power consumption bluetooth module 130.Low work(
Consumption bluetooth module 130 wakes up up when receiving wake-up signal, is that it is handed over the voice of host side 200 afterwards
Prepare mutually.In embodiment of the present utility model, that presets in voice activated module 120 wakes up key up
Word is arranged by User Defined, can by user after host side 200 voice training through by low-power consumption bluetooth
Module 130 is transmitted to voice activated module 120.
In preferred version of the present utility model, low-power consumption bluetooth module 130 also sends while being waken up
Feedback voice is to audio frequency IC module 150.Audio frequency IC module 150 is used for receiving low-power consumption bluetooth module 130
The voice signal sending.Audio frequency IC module 150 also electrically connects with loudspeaker 160, audio frequency IC module
150 by this transmitting voice signal to loudspeaker 160, and loudspeaker 160 is play this feedback sound, informs
User's bluetooth earphone 100 has been turned on.
From the foregoing, when microphone is in the state of monitoring voice command, at low-power consumption bluetooth earphone
In sleep state, keep extremely low power dissipation, extra power consumption will not be produced when being not connected to wake-up signal, because of
This can reduce the power consumption of this bluetooth earphone to greatest extent such that it is able to extends bluetooth earphone as much as possible
Stand-by time.
After low-power consumption bluetooth module 130 is waken up, interactive voice can be carried out with host side 200.When
When user sends voice command, microphone 110 receives this voice command, and the voice command that will receive
It is forwarded to voice activated module 120.Voice activated module 120 is for the institute's speech commands that will receive
Transmission is to low-power consumption bluetooth module 130.Low-power consumption bluetooth module 130, for the voice command that will receive
Transmitted to host side 200 by low-power consumption Bluetooth link.Host side 200 carries out voice to this voice command
Identifying and processing, and processing result information is converted to voice signal, this voice is believed by host side 200 again
Number by low-power consumption Bluetooth link transmit to low-power consumption bluetooth module 130.Low-power consumption bluetooth module 130 connects
Receive the voice signal that host side 200 feeds back according to voice command and be forwarded to audio frequency IC module 150；Sound
Frequently IC module 150 receives the voice signal of low-power consumption bluetooth module 130 transmission and transmits to loudspeaker 160；
The voice signal that audio frequency IC module 150 receives play by loudspeaker 160.
Illustrate as a example by inquiry weather below.User be directed at microphone 110 say " tomorrow weather such as
What ", microphone 110 forwards it to voice activated module 120, voice after receiving this voice command
Trigger module 120 transmits this voice command receiving again to low-power consumption bluetooth module 130.Low-power consumption
The voice command receiving is transmitted to host side 200 by bluetooth module 130 by low-power consumption Bluetooth link.Main
Machine end 200 carries out speech recognition to this voice command, after identifying the voice command of this inquiry weather, main
Machine end 200 by web search application program from internet hunt weather conditions, after inquiring weather conditions,
The information of this weather conditions is converted to voice signal, for example " tomorrow is fine ", host side 200
Again this voice signal is transmitted to low-power consumption bluetooth module 130 by low-power consumption Bluetooth link.Low-power consumption is blue
Tooth module 130 receives this voice signal and is forwarded to audio frequency IC module 150；Audio frequency IC module 150 connects
