Abstract: Provided is a clamp for fastening a portable electronic device. The clamp comprises two spring biased sliding arms and a spring biased trigger member. Pushing the trigger member toward the body will move the shuttle member upward to unlock both arms for extending thereafter. In response to sandwiching the device between the arms releasing the trigger member will push the trigger member outward and the shuttle member downward respectively for locking the ridges. In a case of the device having its ports provided at one side or both sides thereof, two central, rectangular openings of the arms are adapted to allow the ports to dispose therein for causing no interference to a normal operation of the fastened device. A distance between both arms can be adjusted by sliding one arm toward or away from the other arm or sliding both arms toward or away from each other.

Abstract: To attain a slide mechanism of a portable terminal device which, having a minimal number of parts and keeping the same function as that of a conventional one, enables a substantial production cost reduction, a mechanism relatively slides a first casing and a second casing in a state that the casings are laid over each other in a vertical direction, and is constituted with: a slide case mounted on either one of the first casing and the second casing; a slider slidably accommodated in the slide case and mounted on the other one of the first casing and the second casing; and a resilient means resiliently disposed between the slider and the slide case. The slide case is formed as an integral structure with a guide groove which extends to both ends in a longitudinal direction with the one end thereof being opened. Additionally the slider has a shape which enables the slider to be inserted into the guide groove in an engaged state from the open end side.

Abstract: A space-efficient ergonomic telephony keypad is described which comprises three separate groups of four buttons collectively capable of performing twelve distinct electronic switch operations. Each button is formed for tactile operation. Each group has the four buttons positioned about equally around an imaginary central axis. And, each group of four buttons is positionally rotated about 45 degrees relative to the positioning of an adjacent group of four buttons.

Abstract: A mobile terminal comprising a main housing, first and second sub-housings, each slidably mounted on an upper surface of the main housing such that the first and second sub-housings can slide towards each other or away from each other to open or close a predetermined region of the upper surface of the main housing, and a sliding module. The mobile terminal is structured such that the display apparatus can be opened or closed by the first and second sub-housings, and such that it is easy to operate keypads with both hands when the display apparatus is open, resulting in convenience of playing games or chatting. Additionally, the sliding module of the mobile terminal is structured such that the first and second sub-housings are interlinked with each other, which allows for easy opening and closing of the display apparatus.

Abstract: An electronic device comprises a body. An at least partly covering lid is rotatably mounted to the body by a hinge slideably mounted to the body. The lid is rotatable to an open position, in which open position the lid reveals a key-pad of the electronic device positioned in a front side of the electronic device, above a display. The hinge is resiliently mounted to the body, so that the lid is rotatable to a closed position, in which closed position the hinge retreats to be generally invisible by the covering lid.

Abstract: A frame is provided with an opening allowing insertion of a jig for setting an inner rim of a suspension holder to a proper position. The jig ensures positive alignment of the suspension holder when making connection to the frame. The jig also ensures reliable bonding of a diaphragm to the suspension holder with a bonding agent, since it steadily supports the suspension holder in position during the bonding process. The positioning of the bobbin and a voice coil is thus reliable when being assembled, thereby improving acoustic performance of a speaker.

Abstract: A hearing device is activated by operating the hearing device in an operating mode in a first phase after supplying energy to internal circuitry of the hearing device, by operating the hearing device in a reduced operating mode in a second phase and by operating the hearing device in a selectable operating mode in a third phase. Thereby, the hearing device user can examine a correct functioning of the hearing device before its insertion into the ear. In addition, the hearing device can thereafter be inserted without that a feedback signal is generated.

Abstract: The invention relates to an electromagnetic driver comprising a soft magnetic core in the form of an E with three legs and a back, an alternating field driver, magnetically coupled to the soft magnetic core, for generating an alternating magnetic field in the soft magnetic core, depending upon a sound signal, a constant field driver magnetically coupled to the soft magnetic core for generation of a constant magnetic field in the soft magnetic core, a soft magnetic element for coupling to the plate of the planar diaphragm loudspeaker, lying opposite the back and magnetically closing the legs across at least one small induction gap, whereby the constant field and the alternating field are asymmetrically superimposed such that a resulting force, or a resulting torque on the soft magnetic element, is proportional to the sound signal.

Abstract: A protective grommet for a microphone has an enclosure with an internal cavity. The internal cavity is dimensioned to receive an input end of the microphone therein. A membrane, particularly a mesh, and more particularly a wire mesh, and more particularly a stainless steel wire mesh, is embedded into the enclosure spanning the cavity across the input end of the microphone. In application, the grommet as described is fit over the input end of the microphone.

Abstract: The process of adapting a hearing aid to its wearer is to be simplified. To this end the acoustic conditions in the auditory canal, especially the acoustic impedance, are estimated by measuring the input impedance of the earpiece on the hearing aid. For adjusting the hearing aid it is worthwhile using the mechanical resonance of the system of hearing aid and auditory canal which can be detected with the aid of the input impedance. This is produced by a simplified equivalent circuit diagram from which the corresponding acoustic variables can be obtained.

Abstract: The present invention provides a microphone apparatus. The microphone apparatus includes a housing with an outer surface and an interior chamber. A microphone element is disposed within the interior chamber. The outer surface includes a first substantially planar surface having at least one aperture leading to the interior chamber and a second substantially planar surface intersecting at an angle with the first planar surface.

Abstract: A microphone includes a separate end cover with a sound port. A diaphragm is directly attached to the end cover. The backplate is positioned within the housing against a ridge near an end of the housing. A spacer is positioned against the backplate. The diaphragm engages the spacer when the end cover, with its attached diaphragm, is installed in the housing. The backplate of the microphone has an integral connecting wire that is made of the same material as the backplate. The integral connecting wire may have an inherent spring force to provide a pressure contact with the accompanying electrical components. The integral connecting wire electrically couples the backplate to the electronic components within the housing and transmits the raw audio signal corresponding to movement of the diaphragm. The housing may have first and second ridges on which the printed circuit board and the electret assembly are mounted, respectively.

Abstract: A speaker housing for mounting at least one speaker therein is disclosed. The speaker housing includes a speaker enclosure sealed to a speaker cover. The speaker enclosure includes an opening for sealing a connector attached to a crossover printed circuit board assembly thereto. The connector protrudes through the opening in the speaker enclosure while the printed circuit board to which it is attached compresses a compressible gasket against a wall surrounding the opening in the speaker enclosure, sealing the connector thereto. The chassis wiring is coupled to the connector providing an inexpensive sealed interface between the electronics chassis and the crossover board assembly.

There are provided a receiver (106) provided on a surface (101g) of a first housing member (101a) which is opposed to a second housing member (101b) in a closing state, a speaker (107) provided on a surface (101i) of the second housing member (101b) which is opposed to the first housing member (101a) in the closing state and having a higher output level than the first voice output means, and a control portion (120) for deciding a positional relationship of the first housing member (101a) with the second housing member (101b) and setting an output source for a voice at the start of a voice communication to either the receiver (106) or the speaker (107) corresponding to a result of the decision.

Abstract: The microphones used in hearing devices normally possess different characteristic lines that are to be adapted to one another. For this purpose, the amplitude of an output signal of a first microphone and the amplitude of an output signal of a second microphone are measured. The output signal of the first microphone is subsequently filtered dependent on both measured amplitudes, such that the difference between the two output signals is reduced. One of the two microphones hereby serves as a reference, and an absolute normalization can be foregone.

Abstract: A hearing device and method for handling data in a hearing device that enables writing of the data into a storage location only under certain conditions. The conditions are: the data is being entered by a person who has previously entered data to the hearing device or the data has not been copied from a hearing device of a predetermined type or the hearing device has been enabled to unconditionally accept the data.

Abstract: The invention relates to a microphone. Microphones of very different types and genera have been known for a very long time and are also required for very different applications. Apart from “classical” microphones, microphones are also used in headsets, and frequently microphones are accommodated by mounts, e.g. goosenecks, vibrating mounts, microphone booms and the like. The object of the invention is therefore to avoid the previous disadvantages and to propose an aesthetically attractive solution with which the microphone transducer can be decoupled from the structure-borne sound excitation of the housing. A microphone having a housing and a microphone transducer accommodated by the housing, characterised in that a structure-borne sound decoupling element bearing the transducer is constructed inside the housing.
