Embodiment
Some exemplary embodiments that embody feature of the present invention and advantage will be described in detail in the explanation of back segment.Be understood that the present invention can have various variations on different modes, it does not depart from the scope of the present invention, and explanation wherein and the accompanying drawing usefulness that ought explain in itself, but not in order to restriction the present invention.
See also Fig. 1, it is the circuit block diagram of the volume output regulation circuit of preferred embodiment of the present invention.As shown in Figure 1, volume output regulation circuit 1 of the present invention is applicable to multifunctional paper feeding machine or facsimile machine, but not as limit, volume output regulation circuit 1 of the present invention can comprise holding wire 10, power adjustment unit 11, power conversion unit 14, driver 15 and voice output element 16, wherein, voice output element 16 can be but not be limited to a buzzer.
See also Fig. 2, it is the internal circuit schematic diagram of detecting unit shown in Figure 1, as shown in the figure, detecting unit 12 of the present invention can comprise a comparator 121, comparator 121 receives a dialing tone signal DTin and a variable input voltage vin, and dialing tone signal DTin and variable input voltage vin compared, and export a detected value Y to power controller 13 according to comparison result, and the magnitude of voltage by the variable input voltage vin of control break compares with dialing tone signal DTin, to learn the magnitude of voltage of dialing tone signal DTin, for example, the magnitude of voltage of dialing tone signal DTin is 5V, the start voltage of variable input voltage vin is set to 7V, comparator 121 is compared back discovery dialing tone signal DTin less than variable input voltage vin, and comparator 121 will be exported for example low level detected value Y to power controller 13, this moment, variable input voltage vin was 6V by change setting then, comparator 121 is compared back discovery dialing tone signal DTin once more still less than variable input voltage vin, at this moment, variable input voltage vin is 5V by change setting more then, and compare with dialing tone signal DTin, when comparator 121 is relatively afterwards found dialing tone signal DTin greater than variable input voltage vin, the detected value Y that comparator 121 exports change to power controller 13 is for example high level, and this moment, the variation of the detected value Y that power controller 13 can be transmitted by detecting unit 12 learnt that the magnitude of voltage of dialing tone signal DTin is 5V.
Please consult Fig. 1 again, learn the magnitude of voltage of dialing tone signal DTin when power controller 13 after, then can calculate the conversion multiplying power of the dialing tone signal being carried out the volume amplification according to magnitude of voltage and the default output volume numerical value of dialing tone signal DTin, for example: if default output volume numerical value is 15V, and be 5V by the magnitude of voltage that detecting unit 12 records dialing tone signal DTin, then can calculate and learn that it is 15V/5V=3 that 14 pairs of dialing tone signals of power conversion unit DTin carries out the conversion multiplying power that volume amplifies.
The multiplying power that power controller 13 will come 14 pairs of these dialing tone signals of power controlling converting unit to change according to the conversion multiplying power of calculating gained, driver 15 then is connected with power conversion unit 14 and voice output element 16, in order to the dialing tone signal after receiving conversion from power conversion unit 14, and the dialing tone signal after the 16 output conversions of driving voice output element, because the multiplying power changed of 14 pairs of dialing tone signals of power conversion unit is calculated according to the magnitude of voltage of dialing tone signal DTin and default output volume numerical value and is got, for example: the output result that the magnitude of voltage 5V of dialing tone signal DTin multiply by 3 times of conversion multiplying powers is default output volume numerical value 15V, so the dialing tone volume that voice output element 16 is exported promptly can equal default output volume numerical value, thus, then can keep fixing via the dialing tone volume that voice output element 16 is exported, and the dialing tone signal magnitude difference that can not export because of switch, and problem such as the dialing tone volume that causes voice output element 16 to export is excessive or too small allows the user can know that when desiring to carry out fax program the dialing tone of being exported by voice output element 16 learns the situation of present circuit.
In sum, volume output regulation circuit of the present invention detects the dialing tone voltage of signals value size of being exported by switch by detecting unit earlier, make power controller calculate the conversion multiplying power of this dialing tone signal being carried out the volume amplification according to measured dialing tone voltage of signals value and default output volume numerical value, the conversion multiplying power of the dialing tone signal being changed with the automatic power adjustment converting unit, the dialing tone volume that makes the voice output element be exported promptly can equal default output volume numerical value, can reach the function of the conversion multiplying power of automatic power adjustment converting unit, because the change of switch system or the change of communication environment, and cause the excessive or too small problem of volume to solve.
The present invention must be appointed by those of ordinary skills and executes that the craftsman thinks and be to modify as all, does not take off the scope as the desire protection of attached claim institute.
