Title:
SYSTEM, APPARATUS AND METHOD FOR GENERATING SOUND
Document Type and Number:
WIPO Patent Application WO/2017/045144
Kind Code:
A1
Abstract:
An apparatus and system for generating sound and methods for making and using same. A motor-driving signal(240) with an audio signal(241) component is applied to a motor(300). When driven by the motor-driving signal(240)， the motor(300) thereby can generate a sound that corresponds to the audio signal (241)component. An exemplary sound can include high-quality audio content such as music， speech， or a combination thereof. The motor-driving signal(240) can be produced by modulating a carrier signal with the audio signal(241) and can enable a vibration(370) in the motor(300) for generating the sound. When associated with a mobile platform(900)， the motor(300) can be configured to generate the sound and enable the mobile platform(900) to move. Advantageously， without installing separate audio system hardware， the mobile platform（900） thereby is capable of conveying information that is audible and comprehensible to a human. Communication efficiency between the human and the mobile platform (900) can thus be improved.
