Abstract: The present invention is to provide a display device which efficiently drives light emitting display pixels and which can restrain an excessive increment of an operational voltage outputted from a power supply circuit due to trouble of the circuit or the like. Treating light emitting elements 2 in all the display pixels in a light emitting display panel as objects, a maximum value of the forward voltages is drawn by a multi-input comparator 3a and a peak hold circuit 3b. Based on the maximum value of the forward voltages, a voltage boost circuit 6 switching operates a power FET to supply a boosted output by this operation to a constant current circuit 1 as the operational voltage VH. In the case where the maximum value of the forward voltages increases due to trouble or the like and based on this increment the operational voltage VH excessively increases, the operation of the voltage boost circuit 6 is stopped by a control output from an analog comparator 7a which functions as a voltage limiter.

Abstract: In a speaker device, each inner peripheral edge portion of a conductive damper and an ordinary damper is fixed to an area in the vicinity of a lower end of a cylindrical portion of a connecting member, and each outer peripheral edge portion of them is fixed to a support member. The conductive and ordinary dampers are attached to an area within a constant winding width of a voice coil. When the speaker device is driven, the voice coil bobbin vibrates in an axial direction of the speaker device. The voice coil bobbin sometimes rolls due to various factors. Since a fulcrum of the rolling is within the winding width, a distance r2 from the fulcrum P11 to an intersection of a central axis of the speaker device and a plane surface including a center in the winding width becomes short, and the bobbin hardly rolls.

After the step of forming the first electrodes, piezoelectric elements functioning a SAW touch sensor is formed on a second major surface of the transparent substrate. Furthermore, after the step of forming the piezoelectric elements, the light-emitting elements forming step of forming light-emitting elements on the first electrodes which are patterned in advance is sequentially executed. Since the first electrodes are formed in the form of stripes, the piezoelectric elements can be prevented from being damaged by an etching solution used at this time. After the formation of the piezoelectric elements, since the step of forming the light-emitting elements is executed, the light-emitting elements can be prevented from being damaged by receiving heat in the formation of the piezoelectric elements.

Abstract: A speaker apparatus is configured such that a speaker unit including a single magnetic circuit system, a plurality of vibration systems and a case is housed inside a speaker box. In the speaker unit, magnetic gaps having a magnetic field of the same magnitude are defined by a magnet holder, a magnet and a yoke in each of the vibration systems. In one vibration system and the other vibration system, voice coils are wound around voice coil bobbins in directions reverse to each other. Consequently, the vibration systems are moved in directions opposite to each other by the same force by applying the same electric signal to the voice coil in each of the vibration systems from an amplifier. Therefore, acoustic waves are radiated in the directions opposite to each other.

Abstract: A speaker device includes a terminal member, a connecting member, a conductive damper and a diaphragm. The connecting member has a terminal mounting part. The terminal mounting part has a projecting part and a connecting part. The connecting member has a hole in its upper end portion and a fixing part at its lower end portion. The terminal member is mounted to the terminal mounting part. At this time, the projecting part is inserted into the hole, and the fixing part is inserted into a groove. Thereby, at positions of two spots, the terminal member is physically fixed to the connecting member. The connecting part is connected to the conductive member of the conductive damper. Thus, a soldering operation of the connecting part and the conductive member can be performed easily. Then soldering is performed for the terminal member, a lead wire of a voice coil and the conductive member.

Abstract: A speaker device includes a terminal member, a connecting member and a voice coil. The connecting member has a terminal mounting part, a flat surface and a recessed portion. The terminal member is mounted to the terminal mounting part. On the flat surface, an inner peripheral edge portion of a diaphragm is mounted via an adhesive. A lead wire drawn from the voice coil is drawn along an outer peripheral wall of the voice coil bobbin and inside the recessed portion to be electrically connected to a connecting part of the terminal member. Thus, the lead wire is not sandwiched by the flat surface and the diaphragm. Thereby, at the time of driving the speaker device, pressure is not given to the lead wire drawn into the recessed portion from the diaphragm and the connecting member. The cut of the lead wire can be thus prevented.
