摘要： Disclosed is an arrangement comprising an ultrasonic transducer and a damping element with a longitudinal axis L, which damping element connects the ultrasonic transducer to a housing or measuring tube wall, wherein the transducer has an attachment comprising a surface in contact with a medium, from which surface ultrasonic signals are emitted into a gaseous or liquid medium, and the damping element has at least two annular grooves and an annular mass segment arranged therebetween. The invention is characterised in that the damping element has a first characteristic frequency f
a at which the annular mass segment performs an axial movement parallel to the longitudinal direction of the damping element, wherein this first characteristic frequency is the highest characteristic frequency in the event that there are a plurality of characteristic frequencies at which the annular mass segment performs an axial movement parallel to the longitudinal direction of the damping element, and in that the damping element has a second characteristic frequency f
r , at which the annular mass segment performs a rotational movement, wherein this second characteristic frequency is the lowest characteristic frequency in the event that there are a plurality of characteristic frequencies at which the annular mass segment performs an axial movement parallel to the longitudinal direction of the damping element, and wherein the ratio of the first characteristic frequency f
a to the second characteristic frequency f
r is less than 0.75. Also disclosed is a field device for process measurement technology.-

摘要： Un haut-parleur sous forme de panneau possède un panneau émetteur multimode résonnant, excité à des fréquences situées au-dessus de la fréquence fondamentale de la fréquence de coïncidence du panneau pour produire une efficacité de rayonnement élevée, par l'intermédiaire des mouvements multimodaux à l'intérieur du panneau, contrairement aux nouvements comparables à l'action d'un piston, nécessaires pour les haut-parleurs traditionnels. Le panneau émetteur est un composite revêtu pourvu d'une âme alvéolaire ou similaire et doit être conçu de telle façon qu'il possède un rapport de rigidité en flexion à la masse par unité de surface (en mks) du panneau à la puissance trois d'au moins 10 et, de préférence, d'au moins 100. Un composite revêtu d'aluminium et à âme alvéolaire en aluminium peut répondre facilement à ce critère plus sévère.

摘要： A panel-form loudspeaker has a resonant multi-mode radiator panel which is excited at frequencies above the fundamental frequency and the coincidence frequency of the panel to provide high radiation efficiency through multi-modal motions within the panel, in contrast to the pistonic motions required of conventional loudspeakers. The radiator panel is a skinned composite with a honeycomb or similar core and must be such that it has a ratio of bending stiffness to the third power of panel mass per unit area (in mks units) of at least 10 and preferably at least 100. An aluminium skinned, aluminium honeycomb cored composite can meet this more severe criterion easily.

摘要： Door chime assembly includes a chime base having a rear plate and at least one resonance chamber secured to said rear plate, a tone bar within the chamber and a striking means mounted on the plate for striking the tone bar. The chime base is molded in a single piece and employs at least one living hinge which permits folding of parts of the assembly to form the resonance chamber. The tone bar is mounted on dowels in the chamber of a length which prevents the tone bar from falling off the dowels during transit.

摘要： The present invention relates to a musical instrument for producing a harmonious scale of musical notes. The instrument includes nine separate sound actuators each of which is configured to cause the musical instrument to generate a different frequency selected from the group of frequencies comprising 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz and 963 Hz, the musical instrument being configured such that physically manipulating the sound actuators causes the musical instrument to generate the frequency corresponding to the sound actuator manipulated. The invention is also directed at a system for -writing music to be played with a musical instrument incorporating the harmonious scale of musical notes as described above. The notation system includes a staff of five parallel and horizontal lines separated by four spaces, the first line indicating a fist note of 174 Hz, the space immediately above the first line indicating a second note of 285 Hz, the second line indicating a third note of 396 Hz, the space immediately above the second line indicating a fourth note of 417 Hz, the third line indicating a fifth note of 528 Hz, the space immediately above the third line indicating a sixth note of 639 Hz, the fourth line indicating a seventh note of 741 Hz, the space immediately above the fourth line indicating an eighth of 852 Hz and the fifth line, indicating a ninth note of 963 Hz.
