4 results about "Second sound" patented technology

The present invention provides novel methods and devices for providing audio to players of a gaming machine and to nearby players. According to preferred implementations, sounds intended for a person currently using a gaming machine are distinguished from second sounds intended for persons who are not currently using the gaming machine. The former sounds are directed to the player of the gaming machine by one or more methods and/or devices. For example, the gaming machine may include a device for producing ultrasonic waves (e.g., in a beam) that produce the first sounds via interaction with a medium, a sound dome, a speaker array, or other devices for producing directional sound. The sound may be directed to a predetermined area near the gaming machine. Alternatively, the sound may be directed to an area at or near where the player is detected to be, where the player's player tracking card is detected to be, etc.

The invention discloses a method used for eliminating sound effect switching noise when playing an audio signal, which consists of sampling points. N sampling points constitute a sliding step length, and N is a natural number. When sound effect is switched, smoothing processing is carried out according to the last recorded audio pulse code modulation (PCM) value of audio data blocks before switching and after first sound effect processing and the audio PCM value of second sound effect processing after switching, thus obtaining a new audio PCM value. The invention also discloses an audio playing device. The proposal of the invention can lead the PCM waveform of audio signals before and after sound effect switching to keep smooth transition, thus avoiding sound effect switching noise. The invention needs extremely small calculation amount and storage space and is very applicable to be applied to portable multi-media players.

The invention provides a layout structure of a mobile terminal function device. The function device comprises an earphone and a first function device. The first function device is embedded into a first shell. The earphone is located in an accommodating space between the first shell and a second shell. A mobile terminal comprises an isolating member which isolates a sound outlet channel of the earphone from the accommodating space. The isolating member comprises a first sound guide hole and a second sound guide hole. The first sound guide hole faces the sound outlet face of the earphone, and the second sound guide hole faces the outer portion of the mobile terminal. The first sound guide hole and the second sound guide hole are communicated in the isolating member. The layout structure of the function device has the advantages that space is reversed for a screen display region, and accordingly, high screen occupation ratio is provided; sounds sent out by the earphone can be spread to the outside of the mobile terminal through a channel communicated in the isolating member along the first sound guide hole and the second sound guide hole, so that users can hear the sounds clearly.

The invention discloses a song sound correction method and device, electronic equipment and a storage medium. The method comprises the steps: acquiring first sound wave information of a synthetic song, the first sound wave information comprising pitch to be corrected; adjusting the first sound wave information based on the standard pitch to obtain second sound wave information; and obtaining the synthesized song after sound correction according to the second sound wave information. In the intelligent composition process, the first sound wave information of the synthesized song is obtained, thestandard pitch is adopted to adjust the first sound wave information to obtain the second sound wave information, and sound correction of the song is completed, so that the quality of the synthesizedsong is improved, and the experience effect of a user is improved.
