METHOD AND APPARATUS FOR SUPPLEMENTING LOW FREQUENCY SOUND IN A DISTRIBUTED LOUDSPEAKER ARRANGEMENT
First Claim
1. An audio communication system for generating an audio output for users in a region, the system comprising:
- a plurality of portable communications devices, each said portable communication device being for use by a respective user in said region, each communications device comprising;
a microphone for inputting an audio signal by said user,a loudspeaker for generating an audio output for said user, said loudspeaker being adapted to output said audio output in at least a first frequency band, anda wireless interface for wireless communication to transmit said audio signal from said microphone and receive audio signal derived from a said microphone of at least one other said communications device in said region for generating said audio output by said loudspeaker;
at least one low frequency loudspeaker device having an interface for receiving audio signal derived from said microphone of at least one said communications device in said region, and a low frequency loudspeaker adapted to output a low frequency audio output in said region only in a second frequency band lower than said first frequency band; and
a control unit for communicating with and controlling communications of said wireless interfaces and the or each said interface, wherein said control unit is adapted to receive said audio signal derived from said microphone of at least one said communications device in said region and to broadcast said audio signal to said wireless interfaces and said at least one low frequency loudspeaker device.
