Embodiment 1

[0031] Such as image 3 and 4 as shown, image 3 for figure 1 The structural frame diagram of the first embodiment of the shown multi-motor drive system 1, Figure 4 for image 3 The working flowchart of the multi-motor drive system 2 shown. The multi-motor drive system 2 of the first embodiment provided by the present invention includes a first motor 200 and a second motor 201, a first preamplifier 210 and a second preamplifier connected to the first motor 200 and the second motor 201 respectively The preamplifier 211 , the first phase monitoring module 230 and the second phase monitoring module 231 respectively used to monitor the motion phase of the first motor 200 and the second motor 201 , and the phase controller 22 .

[0032] The phase controller 22 is connected with the first preamplifier 210, the second preamplifier 211, the first phase monitoring module 230 and the second phase monitoring module 231, and according to the first phase monitoring module 230 and the...

Embodiment 2

[0035] Such as Figure 5 and 6 as shown, Figure 5 for figure 1 The structural frame diagram of the second embodiment of the shown multi-motor drive system 1, Image 6 for Figure 5The working flowchart of the multi-motor drive system 3 shown. In the second embodiment of the present invention, the multi-motor drive system 3 includes a first motor 300 and a second motor 301, a first preamplifier 310 and a first preamplifier 310 connected to the first motor 300 and the second motor 301, respectively. Two preamplifiers 311 , a first phase monitoring module 330 and a second phase monitoring module 331 for monitoring the motion phases of the first motor 300 and the second motor 301 respectively, and a phase controller 32 . The difference between the multi-motor drive system 3 disclosed in the second embodiment and the multi-motor drive system 2 disclosed in the first embodiment is that in the second embodiment, the phase controller 32 is only connected with the second front a...

Abstract

The present invention discloses a multi-motor drive system which comprises at least two motors for generating vibration, a preamplifier which is connected to at least one motor and is used for amplifying driving signals inputted to the motors, a phase controller which is connected to at least one of the motors and is used for adjusting the phase of the driving signal inputted to the motor, and a phase monitoring module for monitoring the motion of each of the motors and sending a monitored motor motion phase value to the phase controller, wherein the phase controller changes the phase of the driving signal inputted to the motor according to the received motor motion phase value, and thus the motion of the motor is controlled. The invention provides the multi-motor drive system, through controlling the vibration phases of multiple motors, the vibration amount of the system is large enough, and the sense of vibration is rich.

Description

【Technical field】 [0001] The invention relates to the field of motors, in particular to a multi-motor drive system for portable consumer electronic products and a drive method thereof. 【Background technique】 [0002] With the development of electronic technology, portable consumer electronic products are becoming more and more popular, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc. These electronic products generally use vibration motors for system feedback. Such as mobile phone call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. Such a wide range of applications requires high performance and long service life of the vibration motor. [0003] At present, vibration and tactile feedback have become the basic functions of electronic devices such as mobile phones. When the size of the electronic device is large, such as a large-sized mobile phone, a tablet compu...
