Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail。It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention。
Fig. 1 illustrates the structured flowchart of the equipment for switching headset mode provided by the present invention。As it is shown in figure 1, the present invention provides a kind of equipment for switching headset mode, this equipment includes: receive device 220, for receiving the data bandwidth of the source of sound that audio-frequence player device sends；Whether judgment means 230, be used for the data bandwidth judging described source of sound more than a predetermined value；And switching device 210, it is used for: when the data bandwidth of described source of sound is less than or equal to described predetermined value, described earphone is switched to simulation model；And when the data bandwidth of described source of sound is more than described predetermined value, described earphone is switched to figure pattern。This equipment being used for switching headset mode can realize the automatic switchover of headset mode, when not affecting user's acoustics and experiencing, the pattern according to practical situation automatic switchover earphone, effectively reduces earphone power consumption。
This equipment being used for switching headset mode both may be embodied in earphone or audio-frequence player device。
Fig. 2 illustrates the structured flowchart of audio-frequence player device and the earphone provided in one embodiment of the invention。As in figure 2 it is shown, the equipment for switching headset mode both may be embodied in earphone 200 in an embodiment of the present invention, this earphone 200 is the earphone that simulation model can either be supported can to support again figure pattern。
With further reference to Fig. 2, the present invention also provides for a kind of audio-frequence player device 100, this audio-frequence player device 100 can be that any one can play the terminal of audio frequency, such as mobile phone, PAD etc., audio-frequence player device 100 may include that acquisition device 110, for obtaining the sample rate of sound source data, bit depth and channel quantity；Calculation element 120, for calculating the data bandwidth of source of sound according to described sample rate, institute's bit depth and described channel quantity；And dispensing device 130, for the data bandwidth of described source of sound is sent to being used for switching the equipment (being earphone 200) of headset mode。

In audio-frequence player device, the process of the broadcasting of any audio frequency is all be first PCM (PulseCodeModulation by various different compressed formats decompressions, pulse code modulation) data form, the bandwidth of PCM data form is to determine this quality factor of music tonequality, when PCM bandwidth is determined, if the quality of audio frequency it has been determined that therefore the bandwidth of hardware be not less than the bandwidth of PCM, it is possible to ensure the quality of audio frequency play。
The calculating formula of the bandwidth of PCM data form is the product of the sample rate of voice data, bit depth and channel quantity。In the present invention, the bandwidth of PCM data form refers to identical data with the data bandwidth of the source of sound being mentioned above。
As described in the background art, the simulation model of earphone is generally possible to support fixing sample rate (e.g., 48kHz/44.1kHz) and fixing sampling depth (e.g., 16bit), and the bandwidth that sample rate is the PCM data form of 44.1kHz is:
44.1K × 16bit × 2channel=1411.2Kbps=176.4KB/s
The bandwidth that sample rate is the PCM data form of 48kHz is:
48K × 16bit × 2channel=1536Kbps=192KB/s。
