摘要： An electroacoustic transducer which has at least one stator member with an operating surface and a suspended emitter diaphragm spaced from the operating surface of the stator member to enable the diaphragm to oscillate in response to an applied signal voltage. The diaphragm has increased stiffness in a direction along the diaphragm and within the emitter section to enable the emitter diaphragm to oscillate without applying tension in the direction of stiffness. A clamp member secures the diaphragm to maintain the diaphragm in a fixed position relative to the stator to minimize distortion. The clamp member is positioned to define at least two isolated emitter sections for enhancing the frequency response of the transducer. A method is also provided for generating audio output from an electroacoustic transducer. A stator member with an operating surface is positioned adjacent to an emitter diaphragm, which is suspended and spaced a sufficient distance from the operating surface of the stator member to enable diaphragm oscillation in an emitter section of the diaphragm in response to an applied signal voltage. The diaphragm is configured with increased stiffness longitudinally along the diaphragm and within the emitter section to enable the emitter diaphragm to oscillate without applying tension in the direction of stiffness. A clamp is positioned between the diaphragm and the operating surface of the stator member to maintain the diaphragm in a fixed position relative to the stator. Emitter sections on the diaphragm are established by the clamp to provide complementary resonant frequencies, to enhance the frequency response of the transducer.

摘要： An electroacoustic transducer which includes at least one stator member with an operating surface positioned adjacent to an emitter diaphragm. The stator member is comprised of at least one stiff sheet of paper having perforations for acoustic transparency. The stator also includes a means to develop electrical conductivity and to receive an applied voltage. An emitter diaphragm is suspended adjacent to and spaced a sufficient distance from the operating surface of the stator member to enable diaphragm oscillation in response to an applied signal voltage. This arrangement permits diaphragm movement within at least one emitter section without creating restrictive contact on the operating surface of the stator member. The diaphragm may be composed of paper with electrical conductivity sufficient to receive an acoustic signal voltage from a voltage source and to vibrate as an acoustic emitter with respect to forces applied at the stator member. Alternatively, the stator member may be of conventional construction, and combined with an emitter diaphragm constructed of a paper composition. Electrical contacts are also positioned on the stator member and the emitter diaphragm for coupling to appropriate voltage sources.

摘要： A loudspeaker has a horn adapted to both cause air drag and to direct acoustic waves. A speaker and signal generator are electrically coupled to the speaker and secure to the horn. The loudspeaker is transported over a target and dropped from a high elevation. Upon landing the loudspeaker commences broadcasting a message. A shock absorber may secure to the horn and absorbs some of the shock of impact. Contact sensors or motions sensors may trigger broadcasting a message from the speaker. A portion of the horn may be expandable to increase the size of the horn upon deployment or upon impact with the ground.

摘要： Systems and methods for altering audio for more effective delivery to long range targets. An example of the present invention includes a speaker coupled to a processor and one or more sensors suitable for sensing environmental conditions such as temperature and humidity. The processor reads the output of the sensors and compensates for frequency dependent attenuation likely to occur at the sensed environmental condition. In one embodiment, the user specifies a range that the sound is to travel and an equalization table compensating for attenuation at the desired range is selected according to the user input.
