Method for adjusting the vibration frequency range of a sound producing device with vibrating tongues

摘要

The invention concerns a method for adjusting the vibration frequency range of a sound producing device with vibrating tongues. The device includes an assembly formed of a comb extended by at least one vibrating tongue, said comb having at least one hole for the securing thereof to a support by means of a support jaw and of a tightening element traversing the support jaw and the hole in the aforecited comb. According to the method, the frequency range is adjusted by reducing the free length of the vibrating tongue or tongues by the localized clamping of said tongues between the support jaw and a local counter-support.

1. A method for adjusting a vibration frequency range of a sound producing device with one or more vibrating tongues, the sound producing device including an assembly formed of a comb extended by at least one vibrating tongue, said comb including at least one hole to secure thereof to a support by a support jaw and a tightening element that traverses the support jaw and the at least one hole of said comb, the method comprising:
adjusting the vibration frequency range by reducing a free length of the vibrating tongue or tongues by localized clamping of the tongue or tongues between the support jaw and a local counter-support, wherein the at least one hole is shaped elongated along a direction of a length of the tongue or tongues to provide a movement of the assembly in relation to a region of the localized clamping, and the support jaw and the local counter-support form two jaws that are shaped to intersect in a manner of a pair of crossed scissors.
