Abstract

The invention provides a multi-motor driving device and a method. The device includes an event generation system, a motor system and control system which includes multiple motors, an initial signal issued by the event generation system when an event is generated. The control system includes a control module, a motor selection module, a signal selection module and a driving module. The control module receives initial signal then outputs a motor selection instruction and a signal selection instruction. The motor selection module selects motor control signal of the motor according to the motor selection instruction exported by the control module. The signal selection module exports vibration signal according to signal selection instruction exported by the control module. This disclosure can select a certain motor or multiple motors to vibrate according to actual requirement.

First claim

What is claimed is:

1. A multi-motor driving device, comprising:
an event generation system for sending initial signals when the event is generated;
a motor system including multiple motors;
a control system including:
a control module for receiving the initial signal sent by the event generation system then outputting a motor selection instruction and a signal selection instruction;
a motor selection module for selecting a motor control signal of the motor to be vibrated according to the motor selection instruction outputted by control module;
a signal selection module for outputting a corresponding vibration signal according to the signal selection instruction sent by the control module;
a driving module for receiving the vibration signal outputted by signal selection module and the motor control signal outputted by the motor selection module, then outputting a driving signal to the motor to be vibrated.

2. The multi-motor driving device as described in claim 1 , wherein the control system further includes a signal storage module which includes a number of preset signals, the signal selection module selects corresponding preset signal as a vibration signal from the signal storage module.

3. The multi-motor driving device as described in claim 1 , wherein the motor selection module selects one or multiple motors to be vibrated according to the motor selection instruction exported by the control module.

4. The multi-motor driving device as described in claim 3 , wherein the motor selection module selects a certain one or multiple motors to be vibrated according to the motor selection instruction exported by the control module.

5. The multi-motor driving device as described in claim 1 , wherein a plurality of driving modules are used to drive several motors.

6. A method for driving the multi-motor driving device as described in claim 1 , comprising the steps of:
S 1 : providing an event generation system for sending an initial signal when an event is generated;
S 2 : providing a control module for receiving the initial signal then outputting a motor selection instruction and a signal selection instruction;
S 3 : providing a motor selection module for selecting a motor to be vibrated according to the motor selection instruction then outputting a motor control signal;
S 4 : providing a signal selection module for selecting and outputting a corresponding vibration signal according to the signal selection instruction;
S 5 : providing a driving module for exporting a driving signal which controls the vibration of corresponding motor according to the motor control signal and the vibration signal.

7. The method as described in claim 6 , wherein in S 4 , the signal selection module selects a corresponding preset signals as vibration signal from a number of preset signals in a signal storage module according to the signal selection instruction.

8. The method as described in claim 6 , wherein one or multiple motors to be vibrated are selected according to the motor selection instruction.

9. The method as described in claim 6 , wherein a certain one or multiple motors from multiple motors to be vibrated is selected according to the motor selection instruction.
