摘要： A load is powered by a power source and a capacitive element in series such that the voltage provided to the load is the sum of the voltages of the power source and the capacitive element. A power converter imposing a limit on a flow of current through at least a portion of the power converter is coupled to the power source and the capacitive element, and selectively causes the capacitive element to either be charged or to discharge depending on the amount of current drawn by the load. As the capacitor discharges, the power source is permitted to supply a relatively higher amount of current to the load.

摘要： An apparatus for reducing baffle vibration includes a baffle that is subject to vibration. A first transducer that is seated in the baffle includes a first diaphragm that is acoustically coupled to a listening area in a vehicle and also acoustically coupled to a cavity in the vehicle. A first input signal applied to the first transducer causes the first diaphragm to move in a first direction, thereby generating an acoustic output. A second transducer is mechanically coupled to the first transducer. The second transducer includes a second diaphragm that is acoustically coupled to the first diaphragm and also acoustically coupled to the listening area. A second input signal applied to the second transducer causes the second diaphragm to move in a second direction that is substantially opposite to the first direction to reduce a vibration imparted to the baffle while substantially maintaining the acoustic output.

摘要： A method of virtually tuning an audio system that incorporates an acoustic compensation system, where the audio system is adapted to play audio signals in a listening environment over one or more sound transducers. The acoustic compensation system has an audio sensor located at a sensor location in the listening environment. The transfer functions from each sound transducer to the audio sensor location are inherent. The method contemplates recording noise at the sensor location, and creating virtual transfer functions from each sound transducer to the sensor location based on the inherent transfer functions from each sound transducer to the sensor location. Audio signals are processed through the virtual sound transducer to sensor location transfer functions. A virtual sensor signal is created by combining the audio signals processed through the virtual sound transducer to sensor location transfer functions with the noise recorded at the sensor location.

摘要： A noise-reducing stethoscope comprising a body sound sensor for placement on a body to detect internal body sounds and output in response an electrical signal, an ambient noise sensor, proximate the body sound sensor, to detect ambient noise and output in response an electrical signal, and a difference comparator for accepting the electrical signals from both sensors and providing in response a difference signal, in which the difference signal contribution from ambient noise is less than the contribution from ambient noise to the body sound sensor electrical signal to cancel noise artifacts in the body sound sensor electrical signal.

摘要： A mechanical system for reducing unwanted vibration of a stethoscope chestpiece, which reduces the signal components of the chestpiece output due to sources of vibration other than internal physiologic processes within the patient's body. The system includes a compliance, a mass, and a mechanical resistance element, which together increase transmission loss of external sources of vibration between their source and the chestpiece transducer. Methods of using such a system are also disclosed.

摘要： A loudspeaker system for radiation into the passenger compartment of a vehicle has one or more elongated acoustic waveguides to efficiently transfer sound pressure energy from a loudspeaker driver outside the compartment into the compartment. Preferred embodiments feature two elongated acoustic waveguides separated by the loudspeaker driver mounted on a hard baffle panel. One waveguide has an effective length of one quarter wavelength at the lowest frequency desired to be reproduced by the loudspeaker driver, and the other waveguide has an effective length three times that of the first waveguide. One or both waveguides may be folded upon itself. The loudspeaker system is driven through circuitry providing reduced system response at frequencies that may cause the deflection of the loudspeaker to exceed its maximum limits. This circuitry includes a high pass filter for transmitting spectral components above the lowest frequency to be reproduced, and a notch filter centered at a frequency where the loudspeaker cone excursion characteristic is a maximum. Another circuit includes boosts the audio spectral components, reduced by the notch filter, into the passenger compartment through another loudspeaker system, comprising a ported enclosure having a port resonance at the notch frequency.
