Embodiment Construction

[0045] The following embodiments of the present invention describe the vibration information extraction method based on the current mobile phone architecture. It should be able to obtain information such as the corresponding vibration start time, vibration end time, vibration intensity, and vibration frequency according to the characteristics of the music when playing music ( In the context of the present invention, it is called "vibration information"), and based on these vibration information, the vibration motor of the mobile phone is driven, so that the motor vibrates with the music when the music is played, so as to render the effect of music playback.

[0046] The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of claimed subject...

Abstract

The invention relates to a method and a device for extracting vibration information from an audio file and a vibrating device. The method and the device can acquire vibration control information such as vibration starting time, vibration ending time, vibration strength and vibration frequency from a decoded audio stream by time-to-frequency conversion, weighted energy calculation using frequency as a weight, energy-based vibration threshold determination and other steps. The vibration device can drive the vibration motor of a mobile phone on the basis of the vibration information, so that themotor can vibrate with music played for rendering music playing effect.

Description

technical field [0001] The present invention relates to the technology of generating vibration according to music, in particular to a method and device for extracting vibration information from audio files and a vibration device using the same. Background technique [0002] Studies have shown that when a speaker is used to play music, the skin can perceive the vibrations caused by the propagation of sound waves. This tactile perception can assist the auditory perception, thereby making the music sound more vivid. The vibrating horn is a new technology based on this principle. This kind of horn can not only play music, but also vibrate with the ups and downs of the music. When the user holds the portable playback device to play music, if the vibrating speaker is used, the hand will obviously feel the vibration up and down with the music, so as to experience better music effects. [0003] Although the vibrating horn can naturally change some ups and downs in the music into v...
