چکیده

This paper presents a method of steering audible sound beams generated by parametric arrays in air. A hybrid system consisting of combined electronical / mechanical phased array technique is used. Although commercially available emitter technology has been used and therefore several guidelines known from prior-art phased arrays could not be realized, sufficient beam steering performance has been reached.

Highly directional multi-beam audio loudspeaker

This work presents an audio beam loudspeaker that possesses the capability of emitting multiple audio beams into different directions at the same time. Ultrasonic loudspeakers applying parametric array technology are used to generate highly directional audible sound beams. The loudspeaker itself appears as a single device and can be mounted under the ceiling of a room in order to supply selecte...

Steerable parametric loudspeaker with preprocessing methods

The emerging applications of the parametric loudspeaker, such as 3D audio playback systems, require both controllable directivity and high fidelity at the audible frequency (a.k.a. the difference frequency). Although phased array techniques have been applied and proven adequate to steer the mainlobe of a parametric loudspeaker, and preprocessing methods have been studied to reduce the harmonic ...

Smart directional and diffuse digital loudspeaker arrays

A theory of smart loudspeaker arrays is described where a modified Fourier technique yields complex filter coefficients to determine the broadband radiation characteristics of a uniform array of micro drive units. Beam width and direction are individually programmable over a 180-degree arc, where multiple agile and steerable beams carrying dissimilar signals can be accommodated. A novel method ...

Performance Analysis Of Effect Of Directional Antennas On Energy In Routing Protocol

In this paper we have presented an analytical model for power-aware, multi-hop wireless network nodes equipped with antennas such as omni directional, steerable and switched beam antennas. Complexity is day by day increasing of routing between the nodes because of highly dynamic nature of the mobile ad hoc network results due to frequent change in network topology. However, it may be possible t...
