摘要： The hybrid sound radiation device (100) according to the invention is used for vibrating a heavy-weight rigid plate at audio frequencies. The device comprises a fixed support member (120); a permanent magnet (210), one end of which is fixed to the support member (120); a fixed first coil (220) arranged around the permanent magnet (210), the central axis of which defines a primary axial direction (110); a second coil (240) disposed around the first coil (220) and movable along the primary axial direction (110); an intermediate member (140) to a first side of which an end of the second coil (240) remote from the support member (120) is attached and said intermediate member (140) is guided along guide support members (130) attached to the support member (120) and extending in the primary axial direction (110); a fluid reservoir attached to the second side of the intermediate member (140) opposite the first side, having a side wall of variable length along the first axial direction (110); and wherein a fluid reservoir containing a medium (310) comprising at least one thixotropic fluid and a predetermined mixture of a rheopectic fluid and a magnetorheological fluid, wherein the three-fluid medium (310) has a substantially constant viscosity as a function of frequency. A third coil (330) is arranged around the side wall (320) of the fluid reservoir, the central axis of which is parallel to the primary axial direction (110), wherein a first electrode (340) and a second electrode (350) of opposite polarity are provided in the fluid reservoir at its side connected to the intermediate member (140), the electrodes (340, 350) providing a substantially constant electric field inside the fluid reservoir. The device further comprises a vibrating element (160) in the form of a heavy-weight, rigid, planar plate rigidly connected to the side of the fluid reservoir opposite the intermediate member (140); and control circuits (270, 370) connected to the first, second and third coils (220, 240, 330) and the electrodes (340, 350).

摘要： To reduce the driving loss in the diaphragm, and to ensure a good sound output in the wide bandwidth. It includes a circular coil bobbin at least partly disposed between a yoke and a magnet, a coil wound around the coil bobbin, the coil being configured to be moved with the coil bobbin where a driving current is supplied to the coil, a piezoelectric element having one end coupled to one end of the coil bobbin in a movement direction, the piezoelectric element being configured to be expanded and contracted and moved in a direction same as the movement direction where an electric current is supplied to the piezoelectric element, and a diaphragm having an inner circumference part coupled to another end of the piezoelectric element, and a coupled part of the diaphragm to the piezoelectric element and a coupled part of the piezoelectric element to the coil bobbin are positioned on a straight line in the movement direction.

摘要： In case of a loss of power supply a short-circuit (1, 2) between the corresponding pins of the two IEEE 1394 connectors (3, 4) of a device is established. Preferably this will be achieved by a relay (1) controlling switches (2). If power is available, the relay is powered and the switches are open. The device then behaves like without this extension. If power is lost, the relay 1 is not powered any longer, and the switches (2) are closed. By this way, the device simply disappears from the cluster, which will then be reorganised according to IEEE 1394 rules.

摘要： According to an aspect of the present disclosure, a hearing aid is disclosed. The hearing aid including a vibrator configured to apply a main vibration stimulation onto a skull of a recipient of the hearing aid. The vibrator may include a first assembly which comprises a magnet configured to provide a static magnetic flux and a coil configured to provide a dynamic magnetic flux based on a first current, and the coil may be wrapped around at least a part of the magnet. Furthermore, the vibrator includes a second assembly which includes a vibrator transfer unit and a suspension spring, and wherein the first assembly may be configured to move relative to the second assembly generating a first vibration based on the static and the dynamic magnetic flux, and the first vibration may be transferred to the vibrator transfer unit. Additionally, the vibrator includes a first piezo assembly configured to move based on a second current generating a second vibration, and wherein the first piezo assembly may be connected to the vibrator transfer unit, and when the first piezo assembly moves, a second vibration may be generated, and the second vibration may be transferred to the vibrator transfer unit. The main vibration which is transferred to a skull of the recipient via the vibrator transfer unit may include the first vibration and/or the second vibration.
