摘要： This invention addresses a fundamental weakness in currently common microphones, and their applications in feedback for audio speaker systems. This limitation stems from the fundamental difficulties of typical membrane-type microphones in the frequency range 1-100Hz. The self-noise of membrane-type microphones increases in this range approximately as 1/f, and membrane-type microphones are sensitive to parasitic inertial vibrations, which are usually very important in this frequency range. The removal of these limitations enables the use of such a sensor (APV sensor) for effective feedback in audio speakers, dramatically improving performance in the low-frequency range of 10-100Hz. Without feedback, typical audio speakers suffer severe attenuation and/or distortion in this range.

摘要： The invention relates to a hearing device 1 adapted for placement in, at or near a person's ear, the hearing device 1 comprising a microphone 2, a receiver 4 and a signal conditioning means 3 connected to the microphone 2 and to the receiver 4, the microphone 2 being arranged for receiving acoustical signals from the person's surroundings 7 and converting these acoustical signals into electrical signals and the receiver 4 being arranged for converting electrical signals into acoustical signals and transmitting these into the ear's ear canal 13. The object of the present invention is to provide a small, light-weight hearing device 1. The problem is solved in that the receiver 4 comprises a thermoacoustical transducer 18, which allows for a receiver 4 which may take up less space in the hearing device 1 and may have a smaller weight. This has the advantage of allowing the hearing device 1 to be small and light-weight, thus providing an improved wearing comfort. The invention may e.g. be used in hearing aids for compensating a person's loss of hearing capability.

摘要： Even when compression stress is generated because a volume of a thermal insulation layer 2 is expanded due to oxidized by oxygen in the air, occurrence of cracks and fractures of the thermal insulation layer and a heating conductor 3 caused by the cracks are prevented by dispersing the compression stress. A pressure wave generator comprises a substrate 1, the thermal insulation layer 2 of porous material which is formed on a surface of the substrate 1 in thickness direction, and the heating conductor 3 of thin film formed on the thermal insulation layer 2, and generates pressure waves by heat exchange between the heating conductor 3 and a medium. When a thickness at the center of the thermal insulation layer 2 in width direction W is used as a reference thickness, and it is assumed that distribution of thickness of thermal insulation layer in the width direction is averaged with the reference thickness, porosity in an outer peripheral portion of the thermal insulation layer is made smaller than porosity in the center portion. By making the porosity in the outer peripheral portion of the thermal insulation layer 2 smaller, a number of immovable points on the outer periphery of the thermal insulation layer 2 restricted by the substrate 1 is increased and the positions of them are dispersed, so that the compression stress compressed in the outer peripheral portion of the thermal insulation layer 2 can be dispersed.

摘要： Disclosed are a method, system and controller for simultaneously verifying amplitude and temperature parameters of an electrical-acoustic conversion device, including: inputting a sweep signal to the electrical-acoustic conversion device; testing the amplitude of the electrical-acoustic conversion device while adjusting the gain of the whole frequency band of the sweep signal until the maximum value of the tested amplitude is a maximum amplitude parameter Xmax, and testing the temperature of a voice coil at this moment; and if the tested temperature of the voice coil at this moment is higher or lower than Tmax, gradually reducing/increasing the gain of the sweep signal in the frequency band above a gain improvement frequency point until the tested temperature of the voice coil is Tmax, and then maintaining the gain of the sweep signal for a predetermined period of time and then testing the performance of the electrical-acoustic conversion device, wherein the gain improvement frequency point is greater than the resonance frequency FO of the electrical-acoustic conversion device. The verification method in the present invention enables the temperature of a voice coil of an electrical-acoustic conversion device to reach Tmax while the maximum amplitude reaches Xmax, which more accurately simulates the extreme vibration state of the electrical-acoustic conversion device. The experiment result is more accurate and reliable.
