Abstract
A headset provides for user selectable switching between various frequency responses for the headset through manipulation of mechanical acoustic elements of the headset. The acoustic elements allow adjustment of the transmission paths between a transducer element in the headset and the user's ear canal, and adjustment of the resonant characteristics of the headset housing itself. Adjustment of the transmission path is made by manipulation of ports and openings in and between various volumes containing the transducer and the ear canal, and through the use of various resistant elements along such transmission paths. The user is able to independently and mechanically alter the inductance and resistance along the transmission path, and thereby independently control the high and low frequency response of the headset. Adjustment of the headset resonance is also made by manipulation of ports between interior volumes and external ports, and through variation in the size of the interior volume of the headset, thereby and increasing or decreasing the compliance of transducer. The acoustic switching may be embodied with either discrete or continuous adjustment of the acoustic elements of the …
