Abstract

A portable wireless sound reproduction system includes a first portable housing having a sound signal receiving circuit and controls for processing the sound signal into two signals for transmission by two separate sound signal transmitters located in the same housing. A pair of speakers is detachably connected to the first housing and include receivers for receiving the wireless transmission of signals from the transmitters. The two speakers are adapted to be disposed in side-by-relation with the first housing completely overlying and detachably connected to each of the speakers.

Claims

1. A portable wireless sound reproducing system comprising:

first portable housing means;

sound signal receiving means disposed in said first portable housing means for receiving sound signals from any suitable source;

sound signal control means disposed in said first housing means and connected to said sound signal receiving means for controlling and processing the sound signals received thereby into two separate electrical signals;

a pair of electrical signal transmitting means disposed in said first housing means and connected to said control means for wireless transmission of said two separate electrical signals respectively;

a pair of second portable housing means detachably connected to said first housing means;

receiver means disposed in each of said second portable housing means for receiving the electrical signals transmitted by said pair of transmitting means respectively and speaker means in each of said second portable housing means connected to said receiver means respectively for converting said electrical signals into two audio signals and broadcasting the audio signals wherein said control means in said first housing control the output of the respective speaker means.

2. A portable wireless sound reproduction system as set forth in claim 1 wherein said second portable housing means is comprised of two substantially identical rectilinear housings disposed in side-by-side relation with coplanar upper surfaces, said first portable housing means is comprised of a substantially rectilinear housing having an upper surface with the controls for the system, thereon and having a bottom surface substantially coextensive with the upper surfaces of said pair of second housing means when disposed in side-by-side relation and means for detachably connecting each of said second housing means to the bottom of said first housing means.
