    摘要: A digitally driven headphone suppresses the occurrence of spurious radiation even when directly converting digital signals into sound waves. The digitally driven headphone includes a first sound emission unit, a second sound emission unit, and a signal line. The first sound emission unit includes at least one magnetic body into which the signal line is inserted, a signal processing circuit configured to process digital signals from a sound source, a circuit board on which the signal processing circuit is disposed, a driving part configured to drive the diaphragm in response to digital signals from the sound source, and a diaphragm configured to vibrate in response to driving of the driving part. The signal processing circuit has an output part disposed at an end portion of the circuit board. The signal line is inserted into the at least one magnetic body, and is connected to the output part and the second sound emission unit. The at least one magnetic body is disposed adjacent to the output part.

    摘要: The present disclosure provides a method for testing an apparatus which comprises a set of operational subunits each comprising a moving element, wherein the moving elements move between respective first and second extreme positions, the method comprising: transferring to the apparatus stabilization control commands; transferring to the apparatus first latching-commands for latching to the first extreme position a candidate moving element which is a moving element of a candidate operational subunit; when the first latching control commands are in effect, measuring a first output frequency of an oscillator whose output is coupled to the candidate operational subunit in an electrical coupling setup which causes the output frequency of the oscillator to depend on positions of a plurality of moving elements which comprises the candidate moving element; and based on the first output frequency determining a state of the candidate operational subunit.

    摘要: Provided is an electro-acoustic conversion film that is suitably used for a digital speaker or the like, and that includes a polymer composite piezoelectric body formed by dispersing piezoelectric particles in a viscoelastic matrix formed of a polymer material having viscoelasticity at room temperature, and thin-film electrodes provided on both surfaces of the polymer composite piezoelectric body, in which at least one of the thin-film electrodes is divided into a plurality of regions having the same area, and the respective regions are coupled in parallel and grouped to correspond to a weight of each bit digit of a parallel PCM digital signal. Thus, an electro-acoustic conversion film by which a digital speaker in which reverberation or crosstalk between segments is suppressed is obtained is provided.

    摘要: A digital loudspeaker and a method for operating a digital loudspeaker are disclosed. In an embodiment a digital loudspeaker includes a substrate, a first stator fixed with respect to the substrate, a second stator fixed with respect to the substrate and spaced at a distance from the first stator, and a membrane between the first stator and the second stator. The membrane is displaceable between a first position in which the membrane mechanically contacts the first stator and a second position in which the membrane mechanically contacts the second stator. The first stator and the second stator are arranged to electrostatically move the membrane from a rest position spaced apart from the first position and the second position to the first position and the second position, respectively.
