摘要： To improve the reproduction of audio signals, the signal components of a selected audio frequency range (1) of an audio signal are concentrated in a narrower audio frequency range (II). This is achieved by detecting first signal components in the first audio frequency range (I), generating second signal components in the second audio frequency range (II), and controlling the amplitude of the second signal components in response to the amplitude of the first signal components. As a result, dedicated transducers may be used which are particularly efficient in the narrower frequency range. The original frequency range (I) may contain the lower frequency signal components (bass components) of the audio signal.

摘要： A device (1) is arranged for adjusting the amplitude of an audio signal (x) such that the output of a transducer (2) coupled to the device is equivalent to the output of a reference transducer. The device comprises a first simulation unit (11) for producing a reference signal (y) in response to the audio signal (x), a second simulation unit (12) for producing a further signal (z) in response the audio signal (x), and comparator means (15) for comparing the reference signal (y) and the further signal (z) so as to produce an adjustment signal (a) which is fed to an adjustment unit (10).

摘要： An audio signal may be enhanced by adding enhancement signals, such as harmonics and/or sub-harmonics of the signal's bass components. To avoid any unwanted enhancement signals during soft passages or speech, it is proposed to monitor the audio signal for tonal signal components in a frequency range and to only add the enhancement signals if such tonal signals are detected. A tonal detector (3) may comprise sine and cosine generators whose frequency is preferably equal to a dominant frequency of the frequency range.

摘要： A cooling device (1) using pulsating fluid for cooling of an object, comprising: a transducer (2) having a membrane adapted to generate pressure waves at a working frequency (fw), and a cavity (4) enclosing a first side of the membrane. The cavity (4) has at least one opening (5) adapted to emit a pulsating net output fluid flow towards the object, wherein the opening (5) is in communication with a second side of the membrane. The cavity (4) is sufficiently small to prevent fluid in the cavity (4) from acting as a spring in a resonating mass-spring system in the working range. This is advantageous as a volume velocity (u1) at the opening is essentially equal to a volume velocity (u1′) at the second side of the membrane, apart from a minus sign. Thus, at the working frequency the pulsating net output fluid can be largely cancelled due to the counter phase with the pressure waves on the second side of the membrane resulting in a close to zero far-field volume velocity. Thus a low sound level is achieved, at a low cost, without requiring mechanical symmetry.
摘要翻译： 一种使用用于冷却物体的脉动流体的冷却装置（1），包括：具有适于产生工作频率（fw）的压力波的膜的换能器（2）和包围所述第一侧的空腔（4） 膜。 空腔（4）具有至少一个开口（5），适于朝向物体发射脉动的净输出流体流，其中开口（5）与膜的第二侧连通。 空腔（4）足够小以防止空腔（4）中的流体在工作范围内作为共振质弹簧系统中的弹簧。 这是有利的，因为开口处的体积速度（u1）基本上等于膜的第二侧处的体积速度（u1'），除了负号。 因此，在工作频率下，脉动净输出流体由于与膜的第二侧上的压力波的相反相而可能被大大地消除，导致接近于零的远场体积速度。 因此，以低成本实现低声级，而不需要机械对称。

摘要： An audio driver including a diaphragm with a first side and a second side. The diaphragm is coupled to a transducer element on the second side and is arranged to radiate sound. The transducer element converts an electrical input signal into movement of the diaphragm. The diaphragm is arranged such that a part of the diaphragm at least partly forms a cavity at the second side of an air conduit is coupled to the cavity. The air conduit has a first opening into the cavity and a second opening outside of the cavity. The air conduit and cavity form a resonator which has a resonance frequency that is less than half a free air acoustic resonance frequency of the audio driver.
