Abstract
The invention provides a method for using a single sound channel bluetooth headset to play music, which comprises the following steps: firstly, reading musical file data in an audio playing device, decoding the data into PCM data, secondly, sending the PCM data into a bluetooth chip of the audio playing device, and thirdly, sending the PCM data to the single sound channel bluetooth headset to play by the bluetooth chip. The method for using the single sound channel bluetooth headset to play music, which is provided by the invention, adopts a PCM data mode to realize that the single sound channel bluetooth headset is used to play music files, and has the advantages of low cost and convenient use.
Description
Technical field
The present invention relates to the music field, relate in particular to a kind of method that can use the single sound channel bluetooth headset playing back music.
Background technology
Universal day by day along with portable music player comprises that a lot of portable players of mobile phone can both adopt the bluetooth earphone playing back music, removed the inconvenience that lead brought of conventional earphone like this for the user from, accomplishes hommization more.Yet, present mobile phone all is to adopt I tech clip S to realize music, its process is at first music data to be changed into SBC (Subband Codec) form, asynchronous connected mode by bluetooth sends to I tech clip S then, perhaps directly music file being sent to I tech clip S plays, for single sound channel bluetooth headset, can not realize music at present.On the other hand, because the price of I tech clip S is higher, its use is restricted, and single sound channel bluetooth headset is widely used because of cheap.Therefore, provide the enough single sound channel bluetooth headset of a kind of energy to realize that the method for music is that realistic meaning is arranged very much.
Summary of the invention
The object of the present invention is to provide a kind of method, be intended to solve the defective that single sound channel bluetooth headset in the prior art can not playing back music with the single sound channel bluetooth headset playing back music.
Method with the single sound channel bluetooth headset playing back music provided by the invention may further comprise the steps.
Step a reads the music file data in the audio-frequence player device and data decode is become the PCM data;
Step b sends the PCM data into Bluetooth chip in the audio-frequence player device;
Step c, Bluetooth chip sends to single sound channel bluetooth headset with the PCM data and plays.
Described step a becomes the PCM data by audio decoder software with data decode.
Described step a becomes the PCM data by hardware with data decode.
Described hardware is digital signal processor.
Described audio-frequence player device is a mobile phone.
Described single sound channel bluetooth headset is play after the PCM data that receive are changed into analog signal again.。
Method with the single sound channel bluetooth headset playing back music provided by the invention adopts the PCM data mode to realize using the single sound channel bluetooth headset playing music, has advantage with low cost, easy to use.
Description of drawings
Fig. 1 is a hardware configuration schematic diagram involved in the present invention;
Fig. 2 is the flow chart of the present invention with the single sound channel bluetooth headset playing back music.
Embodiment
For the purpose, technical scheme and the advantage that make invention is clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Shown in Fig. 1, with the mobile phone is example, main thought of the present invention is, according to the bluetooth earphone chip PCM (pulse code modulation) sample rate that can accept, partly set the PCM sample rate of decoding software or hardware at mobile phone, then with music data by decoding software or hardware (digital signal processing chip for example, DSP) be decoded into the data of PCM form, for stereo music, have two-way or multichannel PCM data, need to select one road PCM data wherein to send Bluetooth chip in the mobile phone to, then the music data of PCM form is connected (SCO or eSCO) synchronously by bluetooth and send to bluetooth earphone.Concrete steps are referring to shown in Fig. 2, and the preferred embodiment of the method with the single sound channel bluetooth headset playing back music of the present invention may further comprise the steps:
Step 10: the music file reading of data of from mobile phone, storing;
Step 11: mobile phone becomes PCM (pulse code modulation) data by audio decoder software or hardware with data decode;
Step 12: the PCM data are sent into Bluetooth chip in the mobile phone;
Step 13: Bluetooth chip sends to single sound channel bluetooth headset by connecting (SCO or eSCO) synchronously with the PCM data;
Step 14: single sound channel bluetooth headset is accepted the PCM data by connecting (SCO or eSCO) synchronously;
Step 15: single sound channel bluetooth headset changes into analog signal with the PCM data that receive;
Step 16: analog signal changes into sound by earphone.
By said process, the present invention has realized the purpose of single sound channel bluetooth headset playing music by the PCM data mode.
The foregoing description only is preferred embodiment of the present invention, and the present invention is not limited thereto.For example the present invention not only can be applied on the mobile phone, can also be applied in other equipment with Bluetooth function, for example MP3, PDA, digital camera or the like, its music file that can play not only comprises the file of musical form, also can be broadcast receiver or the like.All any modifications of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
