Abstract
The utility model discloses a directional sound source system comprising hardware devices and super directional loudspeakers. The hardware devices are connected with the super directional loudspeakers. The at least two super directional loudspeakers form a super directional loudspeaker array. The super directional loudspeakers in the super directional loudspeaker array are arranged on a same installing plane and surround a center line perpendicular to the installing plane. Combination modes of the super directional loudspeakers can be used in which the planes of multiple super directional loudspeaker arrays are parallel with the ground so that the sound wave is vertically projected right downwards, or multiple super directional loudspeakers are used to focus so that the sound wave is projected to a listening area in an inclined manner. The directional sound source system may generate a broadband audible acoustic beam which has strong directionality and which is like a light beam of a spot light.
Description
Technical field
The utility model relates to a kind of directional sound source system, it is a kind of New-type loudspeaker array that can carry out voice signal directional transmissions, this super directive property array has the characteristics such as super directive property and transmitting range be far away specifically, can be used for exhibition, family, office and public place of entertainment, the directional sound source system of the aspects such as audio frequency secure communication.
Background technology
The directional sound source system is the novel sound system that a kind of nonlinear interaction when utilizing ultrasonic wave to propagate in air produces the high directivity audible sound.It is loaded into the mode of audio signal with amplitude modulation(PAM) in the high-frequency ultrasonic signal by the nonlinear interaction principle that air-borne sound is propagated, and drives the high power altrasonic transducer array, when producing the high directivity ultrasonic beam, produces the high directivity audio signal beam.In order to produce enough audio signal beams of large sound pressure level, often adopt the directional sound source system of a plurality of super directive property array combination.
Summary of the invention
The purpose of this utility model provides and can be used for exhibition, family, office and public place of entertainment, the directional sound source system of the aspects such as audio frequency secure communication.
Realize that the novel technical scheme of this application is: it comprises hardware unit and audio beam loudspeaker, hardware unit is connected with audio beam loudspeaker, it is characterized in that at least two of audio beam loudspeakers, and composition audio beam loudspeaker array, audio beam loudspeaker in this audio beam loudspeaker array is arranged on the same mounting plane in the same way, and around the center line perpendicular to this mounting plane.
Hardware unit comprises audio player, and one turns many conversion equipments, and signal processing module and power amplifier box, audio player turn many conversion equipments by one and be connected with signal processing module, and signal processing module is connected with the audio beam loudspeaker array by the power amplifier box.
Audio beam loudspeaker comprises shell, is located at a plurality of transducer phonation units and a pad in the shell.
The utility model is made up by a plurality of audio beam loudspeaker arrays, is used for playing different sound sources.Its compound mode is can a plurality of audio beam loudspeaker fronts parallel to the ground, sound wave vertically under projection, also can adopt a plurality of audio beam loudspeakers to focus on, the sound wave oblique incidence is to zone pleasant to hear.The utility model can produce very strong directive property, the broadband audible sound bundle as the spotlight light beam.
The utility model has the advantages that: light, compact design, high directivity, orientable playing audio signal; Accumulation sound field effect under the long-distance communications, nonlinear interaction makes audio frequency can propagate larger distance; Stronger reflectivity can be used for producing special sound effect, such as virtual sound source, around sound field.
The utility model is applied to exhibition, can make and only stand in the sound of introducing that the front part spectators of showpiece can hear showpiece, be applied to family, office and public place of entertainment, can make and only have those people at sound Shu Fangxiang to experience audible sound, mean that people can enjoy individual's acoustic enviroment separately.Be applied to remote orientation transaudient, can be in noisy crowd or environment, playing audio signal is such as orientation broadcast and the conversation at stadiums, industrial site.Be applied to the audio frequency secure communication, such as the directed commander in battlefield, naval vessel and naval vessel, naval vessel and harbour beam communication, and the aspect such as ATM (ATM) speech prompting system.
