Abstract:
An artificial larynx, comprising:a case having a central case component, a rearward case component, and a forward case component that are connected together by threaded engagement of one another to form an artificial larynx case extending along an axis of elongation of the case, the central case component having a cylindrically shaped interior wall that defines a central portion of the case interior, the rearward case component defining a rearward portion of the case interior, and the forward case component defining a forward portion of the case interior;a circuitboard subassembly, a transducer subassembly, a battery subassembly, and a switch subassembly that are disposed within the case interior and interconnected to function as means for producing an artificial larynx tone;the circuitboard subassembly being disposed within the central portion of the case interior, the circuitboard subassembly including a circuitboard having a forwardly facing side and a rearwardly facing side, and the circuitboard subassembly including a set of rearwardly facing battery connectors mounted on the circuitboard;the battery subassembly being disposed within the rearward portion of the case interior, the battery subassembly including a battery having two battery terminals and a spring adapted to bear rearwardly against the rearward case component and forwardly against the battery so that the two battery terminals bear against the set of rearwardly facing battery connectors on the circuitboard; andthe circuitboard subassembly including a radially inwardly extending flange component that is bonded to the cylindrically shaped interior wall of the central case component to function as means for stopping the circuitboard from moving forwardly within the central portion of the case interior in response to the two battery terminals bearing against the set of rearwardly facing battery connectors.
