Abstract:
1. A communication terminal comprising: a housing comprising a first sound cavity portion that is configured to generate sound having a first primary sound when physically tapped; a sound sensing device that is configured to generate an electrical sense signal from an incident audible signal; a tap determination circuit that is configured to determine presence of a component of the sense signal that is associated with a physical tap on the housing and to generate an indication of an operator input based on the determined presence of the component of the sense signal that is associated with a physical tap, and is further configured to identify a component of the sense signal that is attributed to sound from the first sound cavity having the first primary sound, and to generate an indication of a first type of operator input based on the identified component of the sense signal; and a controller that is configured to utilize the indication of the first type of operator input to perform one or more communication terminal functions, wherein the sound sensing device, the tap determination circuit and the controller are at least partially enclosed by the housing.
