    摘要: A device is arranged for producing a driving signal (VM) for a transducer (7), such as a loudspeaker. The driving signal has a frequency substantially equal to a resonance frequency of the transducer and an amplitude controlled by an external signal (VE). The device is arranged for automatically adjusting the frequency of the driving signal to the resonance frequency of the transducer, using a control path (8). The device may be part of a frequency adaptation device (1) for adapting a frequency range of an audio signal to the transducer (7).

    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: An enclosure (1) for an acoustic transducer (2) comprises a first chamber (11) for accommodating the acoustic transducer (2) and a spaced apart second chamber (12), which first and second chambers are acoustically coupled by a coupling section (15). The coupling section may have a smaller diameter than the first and the second chamber. An optional further coupling section (16) may acoustically couple the first chamber (11) to an optional third chamber (13). The volume of the enclosure is distributed over the various chambers, thus providing a relatively large enclosure, even when the first chamber (11) is small. Any non-fundamental resonances induced by the coupling sections (15, 16) lie outside the active region of the transducer (2).

    摘要: A transducer (1) for producing sound in response to an electrical signal comprises an actuator (2) with a magnet (4) and a coil (5), and a vibration surface (3), for example a loudspeaker cone. The actuator and the vibration surface are mechanically coupled. The transducer (1) is designed to operate at substantially its resonance frequency (f0). This results in a very high transducer efficiency, which is particularly relevant for rendering low audio frequencies.
