An acoustic apparatus has permanent magnets 2 and 3, which have north poles and south poles magnetized alternately in a stripe-like fashion, at the front and back of a diaphragm 1, respectively; and has a conductor circuit 4 wired on the diaphragm 1 along the stripe-like poles of the permanent magnets 2 and 3. The method involves the use of the medication Flumazenil in a spray delivery device and to teach the person to self-administer the medication by spraying the medication into either the nasal passage, the buccal mucosol membranes or the pulmonary membranes, whenever the need and the urge to relapse arises, thereby preventing relapse. When the MS is located outdoors, it accesses the IMS through an IEEE 802. The sampling rate of the at least one delta-sigma analog to digital converter stages and the pipeline stages may be adjusted by adjusting their sampling frequency and the number of effective pipeline stages may be adjusted\u2014for example, by adjusting a sampling frequency input at each stage. Each of the first layer and second layer comprise less than about 20 percent airfelt. Consequently, resistance to deflection of the connector is provided, as is a more reliable contact engagement between the connector and the interconnected electronic component.
