Remotely programmable, vandal-resistant voice communications unit
First Claim
1. A remotely programmable voice communications unit, comprising:
- transmitter means for transmitting a voice signal;
receiver means for receiving a voice signal and for receiving a remotely generated programming signal initiated by a remotely located caller without any input from a user of said remotely programmable voice communications unit which is transmitted via a public telephone system, the remotely generated programming signal including telephone number data and control data;
means for coupling the transmitter means and the receiver means with the public telephone system for respectively transmitting and receiving voice signals therethrough; and
remotely programmable unit controller means for storing the telephone number data as a preprogrammed telephone number without any assistance from said user of said remotely programmable voice communications unit in response to the control data included in said remotely generated programming signal received by the receiver means and for controlling the operation of the transmitter means to automatically transmit the preprogrammed telephone number via the public telephone system in response to user actuation for establishing voice communication with a predetermined remotely located telephone unit.

Abstract
A vandal resistant, remotely programmable voice communications unit is capable of being programmed for automatically calling predetermined telephone numbers. The unit is programmed remotely from any touch-tone telephone. A vandal-resistant push-button actuator employs first and second axially spaced apart, slidable seals on a push-button mounted within a housing. The seals absorb transverse blows to a raised portion of the push-button and a lubricant is disposed between the seals to prevent an adhesive inserted by a vandal from disabling the actuator. A speaker and microphone baffle utilizes offset passageways to inhibit the introduction of a pointed object therethrough to prevent damage to the speaker or microphone. A raised push-button actuator is disposed inwardly of an escutcheon and shaped to form a concave, ring-shaped surface therewith, thus to inhibit damage to the inner surface of the escutcheon from a hammer blow. A vandal-resistant pole mounting device clamps about the pole and is fastened by means of a fastener enclosed within a vandal-resistant housing, thus to prevent tampering with the fastener by a vandal in order to prevent removal of the housing and the mounting device from the pole.

9. A speakerphone assembly, comprising:
an outer housing having a transducer mounting wall;
a transducer mounting member having first and second walls in opposing relation, the transducer mounting member being affixed to the transducer mounting wall such that the first wall thereof abuts the transducer mounting wall;
a speaker mounted on the second wall of the transducer mounting member; and
a microphone mounted on the second wall of the transducer mounting member;
the transducer mounting member having at least one first sound aperture extending from its second wall adjacent the speaker to the first wall thereof adjacent the transducer mounting wall and at least one second sound aperture extending from its second wall adjacent the microphone to the first wall thereof adjacent the transducer mounting wall;
the first and second apertures being arranged in the transducer mounting member to extend in mutually deviating directions such that sound from the speaker is projected outwardly of the transducer mounting wall in a direction generally away from a sound path from the transducer mounting wall through the second sound aperture to the microphone whereby sound from the speaker is denied a direct path to the microphone.
