ABSTRACT:
An in-ear monitor for use with either a recorded or a live audio source is provided. The disclosed in-ear monitor combines a single diaphragm driver and a single armature driver within a single earpiece, thereby taking advantage of the capabilities of each type of driver. Preferably, the diaphragm is used to reproduce the lower frequencies while the higher frequencies are accurately reproduced by the armature driver. Such a hybrid design offers improved fidelity across the desired frequency spectrum and does so at a reduced cost in comparison to multiple armature designs. In addition to the two drivers, the disclosed in-ear monitor includes means for splitting the incoming signal into separate inputs for each driver. Typically this function is performed by a passive crossover circuit although an active crossover circuit can also be used. In at least one embodiment, acoustic dampers are interposed between one or both driver outputs and the eartip.
