Abstract: The invention concerns a mobile terminal with at least two transducers (LSm, LSs1, LSS2) used simultaneously as loudspeakers for stereophonic effect. According to the invention, one of said transducers is a main transducer (LSm) with a main working frequency band (Bm) corresponding to at least the phone frequency band, while the other transducer is a secondary transducer (LSs1; LSs2) with a secondary working frequency band (Bs1; Bs2) band different from said main frequency band, the lowest frequencies of said secondary working frequency band (Bs1; Bs2) being greater than the lowest frequencies of said main working frequency band.

Abstract: A mobile device that generates and transmits a human-inaudible acoustic signal, which encodes a symbol sequence representing a binary message, for delivery as audio content, is disclosed. The mobile device encodes the binary message into a sequence of symbols that are each associated with frequency characteristics and generates and transmits the human-inaudible acoustic signal, based on the frequency characteristics of the symbols. A further mobile device that receives and decodes a human-inaudible acoustic signal, which encodes a symbol sequence representing a binary message, embedded within audio content, is disclosed. The mobile device repeatedly performs a frequency domain transformation of samples of the signal to generate a symbol sequence, and performs error correction decoding upon the symbol sequence to determine the validity of the symbol sequence. The mobile device then transmits the symbol sequence as the decoded equivalent of the human-inaudible acoustic signal, once a valid symbol sequence has been identified.

Abstract: An improved ultrasonic lens and associated system is provided. Specifically, there is provided an ultrasonic lens with two sets of parallel sound ports operatively connected to an electrodynamic transducer to extend the working range of both audible and ultrasonic sound signals. The ultrasonic lens and electrodynamic transducer are situated so that the electrodynamic transducer axis and the sound port axes are aligned, whereby a shift in either the x or y axis direction will influence the ultrasound and audible behavior of the sound signal from the electrodynamic transducer.

Abstract: Disclosed, in general, are devices that provide a substantially sound-tight chamber over a sound source while absorbing fields of sounds from the sound source. In general, the devices feature: an anechoic chamber that is configured to receive a sound source in a substantially sound-tight manner; and an anechoic channel that is in fluid communication with the ambient atmosphere. The anechoic chamber is adapted to capture air containing sound energy generated by the sound source, and distribute the air about an internal surface area on the inside of the chamber, wherein the internal surface area is sufficiently large to dampen or otherwise absorb the sound energy. Preferably, the air is directed from the anechoic chamber through an anechoic channel extending therefrom to the ambient to further dampen or absorb the sound energy. In one configuration, the outer wall of the apparatus is configured to reflect ambient sounds.

Abstract: Disclosed, in general, are devices that provide a substantially active noise canceling area over a sound source by causing disruptive interference to all frequency fields of speech sounds from the sound source. In some embodiments, active noise control or active noise cancellation means (“ANC means”) are provided to the device. Said means include one or more active noise canceling speakers for the addition of sound specifically designed to cancel noise from the speech sound source without interfering with the sound source going to the microphone, so the listener can clearly hear what the user is saying.
