Abstract
The invention provides a drive signal for driving a vibrator, which comprises sine wave sequence with variable frequency and can dirive the vibration of the vibrator.
Description
[technical field]
The present invention relates to a kind of drive signal, relate in particular to a kind of sine wave drive signal that drives resonator device.
[background technology]
Communication instrument has to call out usually accepts function, and the prompting that function can produce music such as tune and the tinkle of bells or vibration is accepted in this calling.For allowing vibrating function, communication instrument is enabled resonator device usually, and this resonator device can be sent to actuating force the shell of communication instrument, thereby produces vibration.
Described resonator device, it is provided with vibration unit, this vibration unit has natural frequency, when resonator device being passed to the drive signal (be generally sine wave signal) identical with the natural frequency of vibration unit, vibration unit can produce resonance under this drive signal effect, cause the vibration of resonator device.For example, the natural frequency of the vibration unit of the resonator device on certain mobile phone is 157 ± 5Hz, and the optional frequency of the drive signal of correlation technique is selected any one the single-frequency frequency between 157 ± 5Hz, for example: 152Hz, 153Hz.....161Hz, 162Hz.
The selection method of drive signal is ignored a problem easily in the correlation technique, when the selected frequency departure of the natural frequency of vibration unit and drive signal hour, the amplitude of vibrating elements is more satisfactory; But, when the selected frequency departure of the natural frequency of vibration unit and drive signal is big, the amplitude of vibrating elements can diminish, for example: please join shown in Figure 4, when the natural frequency of vibration unit is 152Hz, during the selected 157Hz of the frequency of drive signal sinusoidal wave, the vibratory output of vibration unit little (128.375dB) can influence the vibrating effect of resonator device like this.
Therefore be necessary the drive signal of correlation technique is improved in fact.
[summary of the invention]
The object of the present invention is to provide a kind of drive signal that can better drive the resonator device vibration.
The object of the present invention is achieved like this: described drive signal is made of the sinusoidal wave sequence of frequency conversion rate, the frequency of described sinusoidal wave sequence in a total cycle comprise frequency range in 152Hz～154Hz " low frequency ", frequency range at 156Hz～158Hz " intermediate frequency " and frequency range " high frequency " at 160Hz～162Hz.
Compared with prior art, the drive signal of the present invention by the sinusoidal wave sequence of frequency conversion rate constitutes can better drive resonator device.

[embodiment]
Drive signal of the present invention (not indicating) is used to drive resonator device.Described resonator device (not shown) is provided with vibration unit (not shown), and the natural frequency scope of this vibration unit is between 157 ± 5Hz, so the selected scope of the frequency of drive signal is 157 ± 5Hz.
Described drive signal is made of the sinusoidal wave sequence of frequency conversion rate, the frequency of this sine wave sequence in a total cycle comprise frequency range in 152Hz～154Hz " low frequency ", frequency range at 156Hz～158Hz " intermediate frequency " and frequency range " high frequency " at 160Hz～162Hz.
Please join shown in Fig. 1-2 first kind of execution mode of the present invention: drive signal with following sinusoidal wave sequence as a total cycle: " 152Hz (3 cycles)～156Hz (1 cycle)～160Hz (3 cycles)～156Hz (1 cycle)～153Hz (3 cycles)～157Hz (1 cycle)～161Hz (3 cycles)～157Hz (1 cycle)～154Hz (3 cycles)～158Hz (1 cycle)～162Hz (3 cycles)～158Hz (1 cycle) ".Here " 152Hz (3 cycles) " be interpreted as: frequency is 3 cycles of sine wave of 152Hz.
As far as possible little for making natural frequency depart from the difference of vibratory output of the vibration unit of 157Hz and the vibration unit that natural frequency is 157Hz, drive signal sine wave of different frequency in one-period is provided with the different minor cycles, for example: " 3 cycles " or " 1 cycle ".
Second kind of execution mode of the present invention (not shown): drive signal with following sine wave as a total cycle: " 162Hz (3 cycles)～157Hz (1 cycle)～152Hz (3 cycles)～157Hz (1 cycle) ".
The third execution mode of the present invention (not shown): drive signal with following sine wave as a total cycle: " 152Hz (2 cycles)～154Hz (1 cycle)～156Hz (1 cycle)～158Hz (1 cycle)～160Hz (1 cycle)～162Hz (2 cycles)～160Hz (1 cycle)～158Hz (1 cycle)～156Hz (1 cycle)～154Hz (1 cycle) ".
Please join shown in Figure 3, first kind of execution mode of drive signal of the present invention acts on the vibratory output (130.113dB) on the resonator device that natural frequency is 152Hz, is that the drive signal of 157Hz acts on the vibratory output (128.375dB) on the resonator device that natural frequency is 152Hz greater than the frequency of correlation technique.Obviously, the drive signal of the present invention by the sinusoidal wave sequence of the frequency conversion rate of some constitutes can better drive resonator device.
The above only is a better embodiment of the present invention; protection scope of the present invention is not exceeded with above-mentioned execution mode; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection range of putting down in writing in claims.
