Abstract
The invention discloses a method for recording and playing sound by a monophonic Bluetooth earphone. The method comprises the following steps: working modes of Bluetooth service programs are switched by application programs or key triggering of Bluetooth earphone; and when the working mode of the Bluetooth work is switched, the service program of the Bluetooth can send messages to a sound driver and inform Bluetooth of the switching of the working mode. Then, a sound driving program can switch a sound access in a sound encoding/decoding chip, thus realizing the function of recording and playing by the monophonic Bluetooth earphone. The method for recording and playing sound by a monophonic Bluetooth earphone provided by the invention has the beneficial effects that a user can listen music and record sound by using the monophonic Bluetooth earphone; as the price of the stereo Bluetooth earphone is far higher than that of the monophonic Bluetooth earphone, the user can use the same efficacy with the stereo Bluetooth earphone by only using the monophonic Bluetooth earphone by applying the invention.
Description
Technical field
The present invention relates to the smart mobile phone that comprises bluetooth and sound codec chip.
Background technology
Along with the development of mechanics of communication, bluetooth earphone is very universal.But at present have only I tech clip S to listen to the music in the smart mobile phone, single sound channel bluetooth headset is only supported the basic function of making a phone call, can not playing back music and recording.Along with the continuous development of society, can not satisfy people's colorful life requirement that becomes increasingly abundant.
Summary of the invention
At above-mentioned defective, a kind of single sound channel bluetooth headset provided by the invention method of recording and play sound, the technical problem of solution are, realize the function of single sound channel bluetooth headset recording and playback, can allow and use the client of single sound channel bluetooth headset can listen to the music recorded voice equally.
A kind of single sound channel bluetooth headset provided by the invention method of recording and play sound, its main application program or bluetooth earphone button trigger the mode of operation of switching the bluetooth service program, after the bluetooth mode of operation is switched, the service routine of bluetooth can send message to sound driver, the transformation of notice bluetooth mode of operation.After this, sound driver can switch the sound passage of sound codec chip inside, thereby realizes the function with single sound channel bluetooth headset recording and playback.
A kind of single sound channel bluetooth headset provided by the invention method of recording and play sound, its beneficial effect is that the user uses monaural bluetooth earphone also can listen to the music recorded voice.Because the price of I tech clip S is higher than single sound channel bluetooth headset far away, use this invention, the user only needs just can use the usefulness same with I tech clip S with single sound channel bluetooth headset.

Embodiment
Join
The PCM of Bluetooth chip and sound codec chip (Pulse Code Modulation) interface, the workflow of single sound channel bluetooth headset playback following (Fig. 1): sound process AC97 (Audio CODEC ' 97) interface that central processing unit 11 plays back is in sound codec chip 12.Sound codec chip 12 is sent to Bluetooth chip 13 to the voice data behind the audio mixing through the PCM port.Final sound spreads out of from bluetooth earphone 14.
Workflow following (Fig. 2) with the single sound channel bluetooth headset recording: sound imports into from the Mike of bluetooth earphone 21, to Bluetooth chip 22.Bluetooth chip 22 is sent to sound codec chip 23 to sound through the PCM port.Final sound codec chip 23 is sent to central processing unit 24 to voice data by AC97, thereby has finished the process of single sound channel bluetooth headset recording.
Realize the flow process of single sound channel bluetooth headset recording playback sound process, as Fig. 3:
After bluetooth service program 32 is received the message of application program 31, change the mode of operation of bluetooth, and bluetooth protocol repertory can tell the mode of operation of sound driver 33 bluetooths to switch to sound driver 33 transmission message.
Such scheme example of the present invention only is used for illustrative purposes, is not in order to limit the present invention.Those skilled in the art can make the various modifications that are equal under the premise of not departing from the present invention, and these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
1, a kind of single sound channel bluetooth headset method of recording and play sound is characterized in that, by joining
The PCM of Bluetooth chip and sound codec chip (Pulse Code Modulation) interface, the work that single sound channel bluetooth headset plays a record.
2, a kind of single sound channel bluetooth headset according to claim 1 method of recording and play sound, it is characterized in that, it mainly triggers the mode of operation of switching the bluetooth service program by application program or bluetooth earphone button, after the bluetooth mode of operation is switched, the service routine of bluetooth can send message to sound driver, the transformation of notice bluetooth mode of operation.After this, sound driver can switch the sound passage of sound codec chip inside, thereby realizes the function with single sound channel bluetooth headset recording and playback.
