Abstract
The acoustic radiating membrane () is for assembly in a music box or a striking watch. The membrane includes a first sheet () having a certain number of cells (), which is secured to a first face of a second sheet () which has no cells. The membrane may also include a third sheet () having a certain number of cells () which is fixed to a second face of the second sheet (). The shape and dimension of the cells are adapted according to the type of material and the note or notes to be radiated by the membrane with uniform amplification within the audible frequency band. The cells () of the first and third sheets are configured in a honeycomb arrangement to occupy most of the surface of the membrane, for the uniform amplification and efficient radiation of the note or notes produced.
