[description of drawings]
Fig. 1 is the structure chart of the recording device of the portable terminal that provides of the embodiment of the invention.
[embodiment]
The present invention is described in detail below in conjunction with drawings and Examples.
Fig. 1 shows the structure of the recording device of the portable terminal that the embodiment of the invention provides, and this recording device comprises baseband chip 11 and audio connecting cord 12.
Wherein, audio connecting cord 12 connects external sound source 13, and obtains audio electrical signal from external sound source 13, the audio electrical signal that obtains is carried out step-down handle.Baseband chip 11 connects audio connecting cord 12, will be converted into the digital signal storage through the audio electrical signal after audio connecting cord 12 step-downs are handled.
In specific implementation process, audio connecting cord 12 is 2.5mm or 3.5mm audio connecting cord.Audio connecting cord 12 comprises resistor voltage divider circuit, and resistor voltage divider circuit comprises first resistance R 1 and second resistance R 2, wherein, and first resistance R 1 and 2 series connection of second resistance R.
Wherein, external sound source 13 can be mp3 player audio output interface, can certainly be other source of sound for the audio output interface line out of computer sound card also, does not enumerate one by one herein.
The operation principle of the recording device of portable terminal is in the present embodiment:
External sound source 13 (such as mp3 player audio output interface) the output audio signal of telecommunication, the audio electrical signal amplitude of mp3 player audio output interface output can reach the hundreds of millivolt;
In external sound source 13 left and right acoustic channels a road connect the sound channel interface 122 of audio connecting cord 12, first resistance R 1 in the audio connecting cord 12 and second resistance R 2 are formed a resistor voltage divider circuit, the audio electrical signal that sound channel interface 122 receives is after the resistor voltage divider circuit step-down is handled, and the audio electrical signal amplitude drops to has only several millivolts;
Audio electrical signal is after audio connecting cord 12 step-downs are handled, be input to the audio electrical signal receiving interface 111 of baseband chip 11 by audio electrical signal input interface 123, and then by the MIC+ of baseband chip 11 end and MIC-termination receipts, because the amplitude of the audio electrical signal that the MIC+ of baseband chip 11 end and MIC-end can receive is very low, and the audio electrical signal after audio connecting cord 12 step-downs are handled just satisfies the range of receiving of MIC+ end and MIC-end;
The embodiment of the invention is with the source of direct external sound source 13 as audio electrical signal, rather than with the source of microphone of the prior art as audio electrical signal, therefore, the baseband chip 11 of the embodiment of the invention need not power supply signal, saved power supply greatly, and the input of the audio electrical signal of external power source 13 can directly enter the MIC+ of baseband chip 11, be converted to the digital signal storage by baseband chip 11, finish sound-recording function.
The embodiment of the invention also provides a kind of portable terminal, and described terminal comprises the recording device that the embodiment of the invention provides, and will repeat no more in this device in above existing detailed description herein.
The embodiment of the invention is on the basis of the existing microphone input channel of portable terminal, by direct source of sound input, avoided in when recording because the unfavorable factors such as noise that external disturbance causes, improved the recording quality of portable terminal, be beneficial to popularizing of portable terminal.
In the above-described embodiments, only the present invention has been carried out exemplary description, but those skilled in the art can carry out various modifications to the present invention after reading present patent application under the situation that does not break away from the spirit and scope of the present invention.
