摘要： Displacement symmetry of a diaphragm is improved to prevent the occurrence of troubles such as diaphragm rolling or the occurrence of abnormal noise, thereby providing high reproduced sound quality. The diaphragm includes an annular edge portion having a convex radial cross section formed by molding a sheet-like member or a film-like member. The edge portion has a plurality of rotationally symmetrical recessed ribs formed by recessing a convex surface. The plurality of recessed ribs includes at least a first rib disposed along a first prescribed line intersecting, at an angle of 45°, a first radial line passing a center point, and a second rib arranged in a position not intersecting but adjacent to the first rib and disposed along a second prescribed line intersecting the second radial line at a predetermined angle of less than 45°.

摘要： There is provided a diaphragm or a dust cap configured to emit a sound wave and an electrodynamic speaker unit including the diaphragm or the dust cap. The speaker unit is configured so that a great peak dip of sound pressure frequency characteristics due to influence of a divided vibration mode can be prevented and excellent reproduced sound quality can be provided. In the diaphragm or the dust cap, a recessed-raised portion imitating a wing of an insect is formed at least on one surface of a diaphragm portion configured to emit a sound wave. Preferably, the recessed-raised portion is formed based on data obtained by measurement of an actual shape of a wing vein of the insect or data of a Voronoi diagram imitating the wing vein of the insect.

摘要： A diffuser which forms a first acoustic passage that sound waves propagate and which radiates the sound waves to an outer diameter direction between a diaphragm and an annular conical surface of a first reflection member, and forms a second acoustic passage the sound waves which pass the opening of the first reflection member propagate and which radiates the sound waves to an outer diameter direction between the annular concave surface of the first reflection member and a conical surface of a second reflection member.

摘要： The present invention is intended to provide constant drive conditions of a relay switch. A relay drive circuit includes a current mirror circuit, a current suppression circuit 26, and a transistor Q3. The current mirror circuit includes a transistor Q1, a first resistor element R1, a transistor Q2, and a second resistor element R2. A relay coil 18 is provided on a current supply path extending from a collector terminal of the transistor Q1 to an earth conductor. The current suppression circuit 26 includes a capacitor C1 as a current suppression element configured to suppress, after conduction between an emitter terminal and a collector terminal of the transistor Q2 has been made, the current flowing through the current suppression element itself as compared to that in such conduction.

摘要： To resolve a problem that a listener feels that sense of localization and sense of connecting with the other channels are lost in case that the listener listens to an audio that is output from a ceiling reflection type speaker in an audio processing device that outputs an analog audio signal to speakers including the ceiling reflection type speaker that makes the audio reflect at a ceiling.A DSP 5 performs low-pass filter processing that extracts low frequency component from a digital audio signal, high-pass filter processing that extracts high frequency component from the digital audio signal, delay processing that delays the low frequency component of the digital audio signal that is extracted by the low-pass filter processing, and composition processing that composes the low frequency component of the digital audio signal that is delayed by the delay processing and the high frequency component of the digital audio signal that is extracted by the high-pass filter processing as audio signal processing.

摘要： An electronic device includes a volatile memory; a non-volatile memory which is for storing firmware; and a circuit, wherein the firmware includes firmware body and loader which is for rewriting the non-volatile memory, and the circuit, judges whether the firmware is being rewritten or not based on a first mark when activating, judges whether the loader is being rewritten or not based on a second mark when it judges that the firmware is being rewritten, copies the loader which is copied to the other position of the non-volatile memory to the volatile memory when it judges that the loader is being rewritten, and executes the loader which is copied to the volatile memory and rewrites the firmware which is stored in the non-volatile memory.
