2388 results about "Sound box" patented technology

A sound box or sounding box (sometimes written soundbox) is an open chamber in the body of a musical instrument which modifies the sound of the instrument, and helps transfer that sound to the surrounding air. Objects respond more strongly to vibrations at certain frequencies, known as resonances. The frequency and strength of the resonances of the body of a musical instrument have a significant impact on the tone quality it produces. The air inside the chamber has its own resonances, and these interact with the resonances of the body, altering the resonances of the instrument as a whole. The sound box typically adds resonances at lower frequencies, enhancing the lower-frequency response of the instrument.

Method for compensating delay and frequency response characteristics of multi-output channel sound system

ActiveCN103414980APhase coincidenceConsistent frequency response characteristicsFrequency/directions obtaining arrangementsFilter (signal processing)Medium frequency
The invention discloses a method for compensating delay and frequency response characteristics of multi-output channel sound system and system implementation thereof. The method comprises the following steps that firstly, phase difference between channels of a multi-channel output device is measured, so that the situation that the multi-channel output device itself is in the state of synchronously outputting signals is ensured; then the delay of the signals which are output by the multi-channel output device and pass through a signal processing system, a loudspeaker box and a space transmission routine to reach a specific audition area is estimated through a delay estimation method, and delay compensation is conducted on the channels by comparing delay difference between the channels; finally, an FIR frequency response compensating filter is designed and achieved according to actually detected frequency response curves of a signal transmission routine, and the part above the low and medium frequency in the frequency response curves of the multiple channels is compensated into a straight line through the filter as far as possible. By means of the method, when sound waves transmitted out of each loudspeaker box reach the audition area, the phases of the sound waves are basically the same, and the frequency response characteristics of the channels are basically the same.

Sound source positioning method of intelligent sound box, intelligent sound box and computer readable medium

The present invention provides a sound source positioning method of an intelligent sound box, the intelligent sound box and a computer readable medium, wherein the method comprises the steps of obtaining a first voice signal carrying a preset awakening word, sent by a target sound source and received by at least two sets of signal reception modules on the intelligent sound box if the situation ofneeding to acquire the voice signal sent out by the target sound source is determined; obtaining the time difference of the two signal reception modules in each signal reception module pair for receiving the first voice signal; according to the first voice signal and the time difference of each signal reception module pair for receiving the first voice signal, determining the orientation of the target sound source sending out the first voice signal. According to the technical scheme of the present invention, the target sound source can be positioned on a scene of more sound sources, so that the intelligent sound box can only acquire the voice signal of the target sound source in the positioned direction, and further provide the services to a user corresponding to the target sound source. Moreover, the functions of the intelligent sound box also can be enriched effectively, so that the intelligent sound box is more flexible and convenient to use.
