Abstract:
A method of combining at least two audio signals for generating an enhanced system output signal is described. The method comprises the steps of: a) measuring a sound signal at a first spatial position using a first transducer, such as a first microphone, in order to generate a first audio signal comprising a first target signal portion and a first noise signal portion, b) measuring the sound signal at a second spatial position using a second transducer, such as a second microphone, in order to generate a second audio signal comprising a second target signal portion and a second noise signal portion, c) processing the first audio signal in order to phase match and amplitude match the first target signal with the second target signal within a predetermined frequency range and generating a first processed output, d) calculating the difference between the second audio signal and the first processed output in order to generate a subtraction output, e) calculating the sum of the second audio signal and the first processed output in order to generate a summation output, f) processing the subtraction output in order to minimise a contribution from the noise signal portions to the system output signal and generating a second processed output, and g) calculating the difference between the summation output and the second processed output in order to generate the system output signal.
Abstract:
An earphone system (1; 23) comprising a wireless earphone (2; 20, 21) and a portable holding device (3; 22). The earphone (2; 20, 21) comprises an ear hook (8) for attaching the earphone (2; 20, 21) to the ear (14) of a user. The holding device (3; 22) comprises an outer surface (25) with an earphone recess (4; 30, 31) adapted for receiving the earphone (2; 20, 21) with the ear hook (8), such that the ear hook (8) follows the outer surface (25) of the holding device (3; 22), and attachment means for attaching the earphone (2; 20, 21) in the earphone recess (4; 30, 31).
Abstract:
Communication unit comprising a housing (1) in which at least one transducer is placed, and on which a microphone arm (2) is suspended. The housing also has an ear hook (6) for fastening the communication unit to the head of a user. The microphone arm (2) is pivotally connected to the housing (1) by a hinge link (3,4,5) at an outer area of the housing, and so that the microphone arm (2) can be moved between a position in which it lies up against the housing (1), and a position in which it extends away from the housing. The microphone arm has a length, which in the main is less than or of the same order as the greatest extent of the housing, so that in the folded-in state the microphone arm does not project out over the circumference of the housing.
Abstract:
The earphone housing is essentially mirror symmetric about a first plane, which is orthogonal to the first side, and which extends through the wire position and the center of the earphone housing. The wearing device extends from the earphone housing at an attachment position, which lies at the upper end of the earphone housing. The attachment position can be a first attachment position for holding the earphone housing at the left ear or a second attachment position for holding the earphone at the right ear. The first and the second attachment positions are mirror symmetric located about the first plane.
Abstract:
A communications system and a method of detecting and learning new ringtones in an automatic manner, comprising a desk phone (1), a hook switch, a ringtone detector (3), and a communications device (2). In a first embodiment a mechanical hook switch device is connected to the desk phone (1), and in a second embodiment an electronic hook switch unit (9) is connected to the desk phone (1). The ringtone detector (3) adaptively sets the filter and amplifier parameters according to the sensor position and pick-up sensitivity. The ringtone detector (3) automatically detects and learns the characteristics of new ringtones. The communications device (2) may comprise a base station (6) and a headset (7).
Abstract:
A battery powered electronic device (1) comprising a housing (2) and a movable part (3) extending from the housing (2). The movable part (3) is movably attached to the housing (2), such that it can be moved between a compact position and an extended position. The electronic device comprises a switch, which is adapted to sense, whether the movable part (3) is in the compact position or not, and the switch is utilised to switch the electronic device (1) On, when the movable part (3) is in the extended position, and Off, when the movable part (3) is in the compact position. The electronics of the device (1) is adapted to be set to off or into a low-power shipping mode, all though the movable part (3) is in the extended position.
Abstract:
The USB device (e.g. an audio class device) comprises a USB bus interface that connects to an upstream USB port and a USB logical device that provides first USB endpoints for upstream communication on a first channel. The USB host comprises a USB host controller that connects to a downstream USB port, and a USB driver that provides second USB endpoints for downstream communication on a second channel; wherein the USB host operates concurrently with the USB device. The processor is configured to communicate data between the first channel and the second channel via the first USB endpoints and the second USB endpoints, respectively.
Abstract:
An earhook (1), for example for a headset, to be worn around the root of the auricle (14) in the postauricular sulcus. The earhook (1) extends between a first end (5) and a second end (6) and has at least a first (2) and a second (3) curved element interconnected at the first end (5). Each curved element (2, 3) has a concave first side pointing forward towards the root of the auricle (14) and a convex second side pointing away from the root of the auricle (14) when worn. The curved elements (2, 3) are arranged with lateral distance (w) seen in a direction essentially perpendicular to the side of the head.
Abstract:
A headset (1; 101; 102) comprising a housing (2; 102; 103) and a microphone arm (3; 103; 203). The microphone arm (3; 103; 203) is connected to a hinge member (4; 104; 204), which is pivotally connected to the housing (2; 102; 103) such that the microphone arm (3; 103; 203) can be rotated about a first pivot axis (P1; P101; P201) between a first position, in which it lies along a first surface (9; 109; 209) of the housing (2; 102; 202) and a second, extended position in which it extends away from the housing (3; 103; 203). The microphone arm (3; 103; 203) is movably connected to the hinge member (4; 104; 204) so that the microphone arm (3; 103; 203) can be moved into a third position, in which it lies along a second surface (10; 110; 210) of the housing (2; 102; 202).
