摘要： A parametric transducer which includes a support member extending along an x-axis and a y-axis and having opposing front and back surfaces. The support member (102) includes an array of parallel ridges (108) extending along the x-axis and spaced apart along the y-axis at predetermined separation distances. The ridges have forward, film contacting faces (112) to support an emitter film (114) in a desired film configuration for emitting parametric output. An electrically sensitive and mechanically responsive (ESMR) film is disposed over the support member with one side of the ESMR film (114) being captured by the film contacting faces, and with arcuate sections aligned with and positioned between the parallel ridges. The film contacting faces mechanically isolate each of the arcuate sections (110) of ESMR film from adjacent arcuate sections.

摘要： A sound emitting device (10) for providing at least one new sonic or subsonic frequency as a by-product of emitting a waveform of at least two ultrasonic frequencies whose difference in value corresponds to the desired new sonic or subsonic frequency. The device includes a parametric emitting perimeter or plurality of emitter segments (13) positioned around a central open section (15). This open section (15) is structured with a diagonal width greater than a cross-sectional diagonal of the parametric emitting perimeter. An ultrasonic frequency source (60) and sonic/subsonic frequency generator (62) are coupled together to a modulating circuit (61) for mixing an ultrasonic frequency signal with an electrical signal corresponding to the at least one new sonic or subsonic frequency. The modulator output is coupled to the emitting perimeter (64) which comprises ultrasonic frequency emitting material for propagating the mixed waveform into air for demodulating the waveform to generate the at least one new sonic or subsonic frequency.

摘要： A system (Fig. 2) configured to dynamically adjust the ultrasonic carrier level in a parametric array system in response to changing source signal input levels, and which employs a look-ahead delay strategy (delay line) to enable optimal modulation of the carrier wave to eliminate constant ultrasonic carrier emission (dynamic carrier controller/expander) and reduce the ultrasonic carrier emission to what is actually needed to accomodate the db range of the source material, and at the same time, to also minimize noticeable distortion and sound artifacts of a high-power ultrasonic carrier, and/or distortion/artifacts arising from modulation of an ultrasonic carrier to reduce average power output; and thus it realizes advantages of carrier modulation based on source-signal level, while minimizing inherent drawbacks of carrier modulation.

摘要： A parametric loudspeaker system using improved modulators to compensate for the non-linearity of the parametric process in air (NLD) when driving the air at saturation levels and below saturation levels. The parametric loudspeaker uses a preprocessed (Nth order distortion compensator) single sideband (SSB) modulator that offers ideal linearity as characterized by square root pre-processed double sideband modulators but with a lower carrier frequency and without the wide bandwidth requirements. By eliminating some or all of the lower sideband the carrier frequency can be reduced without producing sideband frequencies in the audible range. Lower operational frequencies result in greater translation efficiency and greater output capability before reaching the saturation limit of air. A preprocessor minimizes the effects of saturation limits for double sideband, truncated double sideband or single sideband processing to achieve superior output.
摘要翻译：参数化扬声器系统使用改进的调制器来补偿空气中参数过程（NLD）的非线性，当在饱和水平和低于饱和水平下驱动空气时。参数扬声器使用预处理（第N阶失真补偿器）单边带（SSB）调制器，其提供理想的线性度，其特征在于平方根预处理的双边带调制器，但具有较低的载波频率并且没有宽带宽要求。通过消除部分或全部低边带，可以减小载波频率，而不会在可听范围内产生边带频率。较低的操作频率在达到空气饱和极限之前会产生更大的翻译效率和更大的输出能力。预处理器最大限度地减少双边带，截断双边带或单边带处理饱和度限制的影响，以实现出色的输出。
