摘要： A sound source device of a horn according to one aspect of the present invention includes: a diaphragm; a movable iron core connected to the diaphragm through a support point; and a coil (bobbin and winding) into which a driving signal is inputted. The driving signal includes a first signal component that resonates with the diaphragm and a second signal component of a second frequency that resonates with the movable iron core of a first frequency and has a chord relationship with the first frequency. The support point is provided at a position eccentric from the center of the diaphragm, and the movable iron core is structured such that a gravity center is displaced further in an eccentric direction than the support point.

摘要： A portable ultrasonic underwater sensor 15 has a piezoelectric element 21 disposed in a case 22 constructed as a cylinder 24 and having a truncated cone 25 both being integrally and axisymmetrically formed so as to constitute a vibrator 22A. A piezoelectric element 21 and the vibrator 22A are bonded together with a center of the piezoelectric element 21 matches the center of a reverse face of the truncated cone 25 of vibrator 22A, whereby the vibrator 22A is entirely resonant in a vibration mode in which flexional vibration at the center of the truncated cone 25 is a maximum amplitude, and wherein means for holding the vibrator 22A is located along a vibration nodal line on an external side face of the vibrator 22A.

摘要： An electric horn has a diaphragm driven by a plunger which is vibrated by a coil having a pole piece. A small air gap between the plunger and the pole piece is required to assure that they will not touch during vibration. The gap is adjusted by assembling the horn with the gap small enough to permit the plunger to be pulled into contact with the pole piece by magnetic force when a preset direct current is applied to the coil. After assembly a calibration procedure is to apply the preset current to the coil, mechanically pull the pole piece away from the plunger until the diaphragm force overcomes the magnetic force causing the plunger and pole piece to separate, electrically detect the time of separation, and then stop or optionally pull the pole piece an additional fixed amount to set the required gap. Apparatus automatically performs the calibration procedure.
摘要翻译：电喇叭具有由柱塞驱动的隔膜，其由具有极片的线圈振动。需要柱塞和极片之间的小气隙，以确保它们在振动期间不会接触。通过将喇叭组装成足够小的间隙来调节间隙，以允许当预设的直流电被施加到线圈时通过磁力将柱塞拉动与极片接触。组装后，校准程序是将预设电流施加到线圈，将极片机械地拉动离开柱塞直到隔膜力克服磁力使柱塞和极片分离，电检测分离时间，然后停止或可选地拉动极靴额外的固定量以设定所需的间隙。仪器自动执行校准程序。
