    • 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.
    • 本发明涉及适合放置在人的耳朵处或附近的助听设备1,助听设备1包括麦克风2,接收器4和连接到麦克风2和接收器4的信号调节装置3, 麦克风2被布置用于接收来自人的周围环境7的声音信号并将这些声学信号转换成电信号,并且接收器4被布置用于将电信号转换成声学信号并且将这些信号传输到耳朵的耳道13中。本发明的目的 将提供一种小型轻量级听力装置1.该问题通过以下方式解决:接收器4包括热声换能器18,该热声换能器18允许接收器4在听力装置1中占用较小的空间并且可具有较小的 重量。 这具有使听力装置1小而轻的优点,从而提供改进的佩戴舒适性。 本发明可以例如 用于助听器补偿一个人的听力丧失能力。

    • 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.
