Abstract
The invention discloses a motor vibrating along with music amplitude and application. An audio signal is subjected to signal amplification and an envelope signal is acquired; the level of the envelope signal and the preset threshold level REF are subjected to voltage comparison to generate 0-1 signal, namely the signal with voltage greater than VREF is of high level and the signal with voltage less than VREF is of low level; then, a motor driving circuit is controlled by using the high level and low level, so that the high-level motor vibrates and the low-level motor does not vibrate; and thus, the aim of realizing pure hardware that the motor fluctuates along with the audio amplitude is fulfilled. The mode comprises user experience that the motor on the mobile terminal vibrates along with music, so that the interestingness of sounds such as incoming call ringing tone of a mobile terminal user, MP3, alarm clock bell, keystroke and the like and mutual operation of the motor is improved.
Description
Technical field
The present invention relates to a kind of motor, relate in particular to a kind of motor and application with the music amplitude vibrations.
Background technology
Along with the development of technology, portable terminal has become the indispensable means of communication of people's daily life, and the tinkle of bells and motor are two kinds of indispensable functions of present portable terminal, but these two functions of mobile phone all are independent existence at present, and is not related especially on signal.The utility model mainly passes through the amplification to audio signal; Obtain the envelope of audio signal then; Again this envelope is compared with setting threshold level, the vibration that the high-low level after is relatively controlled motor whether, thereby reach the novel user experience that motor vibrates with music rhythm.
Summary of the invention
To not linking mutually of prior art mobile phone music and motor, the novel designs and the application that the object of the present invention is to provide a kind of implemented with low cost motor to vibrate with music rhythm.
The present invention realizes through following technical scheme:
A kind of motor and application with the music amplitude vibrations, described audio signal is amplified through signal and is obtained envelope signal, and envelope signal level and predefined threshold level REF carry out voltage ratio; Produce the 0-1 signal, promptly voltage is higher than the high level that is of VREF, is lower than the low level that is of VREF; Utilize this high-low level control motor drive circuit then; The high level motor vibrations, the low level motor does not vibrate, thereby reaches the pure hard-wired purpose that motor rises and falls and moves with audio amplitude.
Described MP3O_UTL is the audio frequency output from mobile phone base band chip, the A point audio signal after obtaining amplifying after amplifying through the inner first order signal of D403; Through R424, VD402, R425, the detection of C421 obtains B point signal after getting audio frequency envelope circuit; B point signal compares with reference voltage in that D403 is inner, and the 0-1 level control motor drive circuit of the generation after relatively produces motor drive signal, and promptly C point signal is used for CD-ROM drive motor.
Description of drawings
Fig. 1 is a principle of the invention block diagram;
Fig. 2 realizes that through the SGM4834 chip for driving motor is with music amplitude vibrations realization figure for the present invention;
Fig. 3 realizes that through discrete elements such as two triodes motor is with music amplitude vibrations realization figure for the present invention.
Embodiment:
As shown in Figure 1, described audio signal is amplified through signal and is obtained envelope signal, and envelope signal level and predefined threshold level REF carry out voltage ratio; Produce the 0-1 signal, promptly voltage is higher than the high level that is of VREF, is lower than the low level that is of VREF; Utilize this high-low level control motor drive circuit then; The high level motor vibrations, the low level motor does not vibrate, thereby reaches the pure hard-wired purpose that motor rises and falls and moves with audio amplitude.
As shown in Figure 2, described MP3_OUTL is the audio frequency output from mobile phone base band chip, the A point audio signal after obtaining amplifying after amplifying through the inner first order signal of D403; Through R424, VD402, R425, the detection of C421 obtains B point signal after getting audio frequency envelope circuit; B point signal compares with reference voltage in that D403 is inner, and the 0-1 level control motor drive circuit of the generation after relatively produces motor drive signal, and promptly C point signal is used for CD-ROM drive motor.
As shown in Figure 3, described MP3_OUTL is the audio frequency output from mobile phone base band chip, through R4, R3, and C1, R2, R1, R5, NPN transistor VT1 forms audio amplifier circuit, the audio signal A point signal after obtaining amplifying; VD1 is that magnitude of voltage is the voltage stabilizing didoe of VREF=2.5V, annotates: but the TL431AIDBZR voltage stabilizing didoe of type selecting TI.C2, VD1, R6, R7, VT2 constitute the envelope comparison circuit of A point signal and VREF, and when A point signal amplitude during greater than VREF, the B point voltage is 2.5V, triode VT2 conducting, the C point voltage is 1 (being high level); Otherwise, when A point signal amplitude during, not conducting of VD1 less than VREF, further not conducting of VT2, the C point voltage is 0 (being low level); R9, VT3, C3, VD2, M1 constitutes motor drive circuit, when the C point voltage is high level, VT3 conducting, motor operations; Otherwise motor is not worked.
