Embodiment
Describe the speaker volume display unit and the method thereof of the portable terminal device among the present invention with reference to the accompanying drawings in detail.
In an embodiment of the present invention, for making the basic technological thought of clear and definite the present invention omit detailed description at known function and structure.
Fig. 3 is the structured flowchart of the speaker volume display unit in the embodiment of the invention, and as shown in Figure 3, it includes following several sections: memory 310 is used to store the outside music file of downloading; Display part 330 is used to show the display the play output size of music of MP3 music file catalogue and frequency spectrum form; MIDI handling part 320 receives digital MP3 data and is stored in the above-mentioned memory 310, plays the music file that the user selects and also outputs to loud speaker (SP); Sound press test section 360, the sound press by loud speaker detects the output size of playing back music; LED portion 350, according to the output of above-mentioned playing back music size glimmer, luminous; Control part 340, the broadcast of notifying the music file that the user selects for above-mentioned MIDI handling part 220 receives the output size of playing back music and above-mentioned LED portion 350 is glimmered from above-mentioned sound press test section 360 simultaneously.
Above-mentioned LED portion 350 includes: the LED that is used to show the LED of open state or incoming call situation and is used for the backlight effect of keypad.
And above-mentioned LED portion 350 can install the LED that glimmers according to the output size of playing back music separately.
As shown in Figure 4, above-mentioned sound press test section 360 is installed in the position that is comparable to loud speaker (SP), and it includes: balance plate capacitor 400 supplies to bias voltage (bias voltage) and changes static capacity according to the sound press of loud speaker; Resistance (R) is used to detect the voltage of the static capacity correspondence of above-mentioned balance plate capacitor 400.
Above-mentioned balance plate capacitor 400 is that the electronics (-) by balance plate 420 adsorbs the capacitor that the principle of (+) electric charge is made.Between two balance plates 410 and 420, be placed with nonconducting material, or the area of above-mentioned two balance plates 410 and 420 is when big, the static capacity of above-mentioned balance plate capacitor 400 will increase, but the distance of above-mentioned two balance plates reduces owing to electric absorption affinity reduces to make static capacity when far away more.
That is, the distance of the capacitance of above-mentioned balance plate capacitor 400 and above-mentioned two balance plates 410 and 420 is inversely proportional to, and is directly proportional with the area of above-mentioned two balance plates 410 and 420.(proportionality constant: DIELECTRIC CONSTANT (permittivity))
The following describes the as above action and the action effect of the embodiment of the invention of structure.
At first, the user stores into the memory 310 by control part 340 from the MP3 music file of outside (computer, internet etc.) download.
Then, the user sets the MP3 play mode and sets MP3 music file catalogue when showing, above-mentioned control part 340 reads in the catalogue data of the music file of storage in the memory 310, and shows in above-mentioned display part 330.
At this moment, when the user selects music file arbitrarily, above-mentioned control part 340 is notified to it in MIDI handling part 320.
Thus, above-mentioned MIDI handling part 320 is play corresponding music file and it is outputed to loud speaker (SP).
Then, the sound press test section 360 that is installed in the close position of above-mentioned loud speaker (SP) will detect the sound press of loud speaker.
Wherein, above-mentioned sound press test section 360 is sound press detecting sensors of utilizing balance plate capacitor 400, above-mentioned balance plate capacitor 400 is by the movable electrode (vibrating membrane) 410 that vibrates displacement according to the sound press of loud speaker, and the fixed electrode (polarity) 420 that aligns with above-mentioned movable motor 410 in the interval that keeps minimum constitutes, when displacement takes place according to the sound press of above-mentioned loud speaker in above-mentioned vibrating membrane 410, with the static capacity of the corresponding with it above-mentioned balance plate capacitor 400 of change.
Thus, static capacity changes corresponding electric charge and will convert load voltage (Vload) to and be sent in the control part 340 by load resistance (R).
Then, above-mentioned control part 340 converts the load voltage (Vload) that transmits in the above-mentioned sound press test section 360 to digital signal, thereby judge the size of the playing back music of output in the loud speaker (SP), and according to above-mentioned judgement make LED portion 350 glimmer, luminous.
Promptly, the present invention utilizes the sound press of loud speaker to detect load voltage in the portable terminal device with MP3 function, judges the output size of playing back music from the rank of above-mentioned detection voltage, and make above-mentioned LED portion 350 glimmer, luminous, thereby make the user visually experience playing back music.
Simultaneously, in said process, the MP3 music file is stored in memory 310 by above-mentioned MIDI handling part 320, but also can directly store by above-mentioned control part 340.
And, in said process, when playing the MP3 music file,, but also can in the flicker operation of LED, in display part 330, show the output size of above-mentioned music file with the frequency spectrum form according to the big or small LED that glimmers of the output of above-mentioned music file.
In addition, above-mentioned LED portion 350 can install most LED separately in the outside of portable terminal device, makes it change flicker or luminous number, flicker or the sequence of light of LED according to the output size of playing back music.
Perhaps, above-mentioned LED portion 350 is backlight LED of key region portion, and its output size according to above-mentioned music file is glimmered or luminous backlight LED, thereby makes the music of user in visually confirming to play.
As above described in detail, effect of the present invention is, utilize the sound press detecting sensor to detect the output size of playing back music among the present invention, and LED is glimmered or luminous according to above-mentioned testing result, thereby the output size with playing back music compared to existing technology is presented at LCD with the frequency spectrum form, can reduce the current drain and corresponding the extending working time of battery.
And the present invention is glimmered LED according to the output of playing back music size or is luminous, thereby makes the user visually experience playing back music, satisfies the satisfaction in user's use.
Above embodiment only limits to illustrate the present invention, but not is used to limit the present invention.
