摘要： A sound source comprising a loudspeaker (6) and a hollow coupler (4) with an open inlet which communicates with and is closed by the loudspeaker (6) and an open outlet, said coupler (4) comprising rigid walls which cannot respond to the sound pressures produced by the loudspeaker (6). According to the invention the loudspeaker (6) comprises a cabinet (8) being narrowed down in the rearward direction. In this manner it is avoided that the cabinet (8) gives a shade from the radiation in the rearward direction, whereby a substantially omnidirectional characteristics is obtained within a relatively large frequency range.

摘要： The displacement of an object of an electrically conducting material is determined. To determine the displacement, an electromagnetic field creating eddy currents in the object is established by means of a transducer being placed adjacent to and spaced from the object, and a first electrical signal which represents the impedance of the transducer is provided. The first electrical signal may be represented by a first vector having first and second components, the first component being a second vector dependent on characteristics of the transducer and on the distance between the transducer and the object, and the second component being a product of a first factor which is a real number and a second factor which is a third vector. Here, the first factor depends on the characteristics of the transducer, the distance between the transducer and the object, and characteristics of the object, and the third vector depends substantially on the characteristics of the transducer. The first electrical signal is processed, which processing includes simulating projection of the first vector onto an axis being generally at right angles to the second component so as to substantially eliminate the dependency on the characteristics of the object. The invention also relates to a unit for linearization of an electrical signal. An input signal is approximated to a polynomial function with positive broken exponents. The polynomial function is used in a feed back loop.

摘要： A method for measuring acceleration or mechanical forces, the acceleration causing inertial forces, uses a transducer or accelerometer in which at least one piezoelectric element is influenced by a shearing force substantially parallel to the polarization axis of the piezoelectric element, where the shearing force is created by a component of a mechanical or an inertial force substantially perpendicular to the polarization axis. A transducer for measuring acceleration or mechanical forces, the acceleration causing inertial forces, includes at least one piezoelectric element and at least two spaced surfaces abutting the piezoelectric element and arranged so that they are mutually displaced by a component of a mechanical or an inertial force acting substantially in a direction perpendicular to the polarization axis of the piezoelectric element. The piezoelectric element is preferably mounted between the free ends of two arms posiitoned on a supporting base, the arms being deformed or tilted in a direction perpendicular to their longitudinal axis by the force or acceleration. Forces or accelerations in three directions may be measured using a single piezoelectric element with a plurality of electrodes. The principles are also useful for the measurement of force or pressure.

摘要： An apparatus for detecting the malfunctioning of an accelerometer (4), where a test signal in form of a pulse is transmitted from a test signal generator (3) to the accelerometer (4) by means of a change-over switch (1, 2) capable of performing a change in such a manner that the response signal from the accelerometer (4) can be transmitted to an analyzing circuit (8) so as to be subjected to a malfunction detection. The change-over switch (1, 2) is adapted to alternately connect the accelerometer (4) either to the test signal generator (3) or to the analyzing circuit (8). In this manner a particularly simple circuit is obtained where the fact is utilized that the response signal in form of a ringing is not selected until the pulse has been transmitted.

摘要： A method and a coupling for reducing the harmonic distortion of a capacity transducer (1), such as a microphone, such as a capacitor microphone, the capacity (Ck) of which is altered in response to a sound pressure on the capacitor electrode (the membrane) by means of a negative capacity. According to the invention the negative capacity is coupled in parallel to the accoustic transducer (1) and dimensioned so as to eliminate the effect of the undesired capacities (CS) causing the distortion. In this manner the harmonic distortion of the capacity transducer (1) is reduced to a minimum.
