  • Publication number: 20080298620
    Abstract: A wearing hook is provided for the behind-the-ear hearing device to improve acoustic stability. The wearing hook being composed of a metal part and a plastic part. The wearing hook is split substantially at a right angle to the sound channel, which runs along the inside of a wearing hook, into a first section and a second section. The first section, via which the wearing hook is mountable on the behind-the-ear hearing device, is substantially composed of a plastic. On the other hand the second section is substantially composed of a metal. The additional mass of the metal reduces the vibrations at the point of the wearing hook so that acoustic stability is improved.

  • Publication number: 20080232626
    Abstract: A volume control module of a hearing apparatus and specifically a hearing device is to be easily replaceable. A volume control module including a mounting element, specifically a PCB, and including a volume control mounted on the mounting element, is accordingly provided. The mounting element, e.g. the PCB, features at least one fixing recess. A pin element is inserted in the housing recess and in the fixing recess in a form-fit and removable fashion. Thus the volume control module can be removed from the housing once the pin element has been removed from the fixing recess. Secure mounting of the volume control module in the housing, but also at the same time rapid replacement of the volume control module, is thereby possible.

  • Publication number: 20080205680
    Abstract: An ear hook is to be able to be tightly attached to a hearing device housing in a simple fashion. To this end, provision is made for it to be possible to clip the ear hook onto the hearing device housing. One of the two parts; hearing device housing and ear hook has a sound outlet tube, which can be inserted into a corresponding opening in the other part. The two parts are detachably fastened to one another in an axial direction in respect of the sound outlet tube by means of a magnetic connection. The magnetic connection ensures that the two components are fitted tightly onto one another, though it enables said two components to rotate in respect of each other.

  • Publication number: 20080199031
    Abstract: A hearing apparatus is to be provided, with which the battery can be exchanged in an almost wear-free fashion. Provision is thus made to magnetically attach a battery compartment or a battery holding device in the housing of the hearing apparatus or hearing device. The battery holding device is inserted into an opening in the housing. A detachable magnetic connection realized by magnetic elements thus exists between the housing and the battery holding device, the principle force component of which runs in the insertion direction. It is thus possible to dispense with plug or snap connections for instance.

  • Publication number: 20080192968
    Abstract: The hearing comfort when wearing hearing apparatuses is to be improved. To this end, a hearing apparatus and in particular a hearing device is proposed, which has a directional microphone with a preferred direction of recording sound. Furthermore, the hearing apparatus has an inclination determination facility, for determining an inclination of the preferred direction of recording sound in respect of the absolute horizontal for instance. An alignment unit then provides for the directional microphone to be aligned as a function of the determined inclination. The directional microphone of a hearing device can thus always be aligned horizontally independently of the movement of the head of a hearing device wearer.

  • Patent number: 7336935
    Abstract: The present invention is to provide a dynamic power control circuit for a wireless communication device, which comprises a power detector, a comparator, a low pass filter and an adder disposed between a radio frequency auto-gain control circuit and an antenna thereof. A reference voltage is imposed on the adder to enable the power detector to detect and output signal voltage to the comparator which compares the received voltage with a specified received voltage limit and outputs a reference voltage to the low pass filter for filtering out the noise of the reference voltage and outputting it to the adder. The adder then adds the reference voltage and the specified reference voltage, and outputs the result to the radio frequency auto-gain control circuit for controlling the output power corresponding to the strength of the received signals.
