20110091052 | Sound and light control apparatus - A sound and light control apparatus includes an audio signal input terminal for receiving an audio signal, a voltage dividing circuit electrically connected to the audio signal input terminal for dividing the voltage of the audio signal into two divided voltages, a control knob electrically connected to the voltage dividing circuit for adjusting the divided voltages, at least one audio signal output terminal electrically connected to the voltage dividing circuit and at least one loudspeaker for transmitting one divided voltage to the loudspeaker, a frequency-divider crossover circuit electrically connected to the voltage dividing circuit for filtering the other divided voltage according to a plurality of different audio frequencies to generate corresponding frequency division voltages, and transmitting each frequency division voltage to a corresponding frequency division voltage output terminal electrically connected to a light emitting diode and enabling the light emitting diode to produce light corresponding to the frequency division voltage. | 04-21-2011 |
20110108695 | Three-dimensional multi-directional rotation support - The present invention is to provide a three-dimensional multi-directional rotation support, which comprises a fixation base, a first connection base and a second connection base each having a plate with two opposite end edges bent at an angle and extended away from the plate to form a parallel portion respectively, wherein both of the parallel portions are parallel to each other and each of the parallel portion is formed with a pivot hole having a plurality of positioning points formed on the periphery thereof, so that the fixation base can be fixed on a plane, the second connection base can be fixed with an object, and the first connection base can be pivotally connected between the fixation base and the second connection base, enabling a user to adjust various angles of the object to a best direction in a three-dimensional space according to actual needs of the user. | 05-12-2011 |
20110116678 | Speaker having a long voice coil bobbin and dampers - The present invention is to provide a speaker having a long voice coil bobbin and a plurality of dampers, wherein each of the dampers is formed with a central hole for connecting to the long voice coil bobbin at a position adjacent to a lower or upper end of a cone frame of the speaker for enabling the long voice coil bobbin to stably vibrate due to the balance effect of the dampers. In addition, since a ratio of 3˜6 is defined between the length of the long voice coil bobbin and winding length of a voice coil unit of the speaker, the long voice coil bobbin is able to perform the true frequency and amplitude of mega bass more precisely and transmit the vibration to a diaphragm of the speaker for enhancing the vibration strength of the diaphragm and improving the sound quality and volume of the speaker effectively. | 05-19-2011 |
20110235845 | Audio radiation type reflective sound box structure - The present invention is to provide an audio radiation type reflective sound box structure, which comprises a hollow cone tube having a first end received in a box, a second end extended out of an opening of the box to form an inclined side wall, and at least one vent disposed adjacent to the first end. When a diaphragm of a speaker mounted on an inner side edge of the second end generates vibrations, compressed air in the hollow cone tube is pushed out of the opening through the vent, and then collides with the outer edge of the inclined side wall and is diffused toward a peripheral direction adjacent to a front side of the speaker along an extension direction of the inclined side wall. Thus, the sounds reflected by the box can be evenly transmitted to a peripheral environment adjacent to the front side of the speaker. | 09-29-2011 |
20110243369 | Device with dynamic magnet loudspeaker - The present invention is to provide a device with dynamic magnet speaker, which comprises a first housing member having a wall and a first magnetic element fixed on an inner surface of the wall; a seat having a first side connected to the first housing member to define a first receiving space between the first housing member and the first side of the seat; and a hollow tube fixedly provided on the seat and corresponding in position to the first magnetic element, wherein a first coil unit is fixedly mounted around the hollow tube, and the hollow tube extends toward the first magnetic element and is either mounted around an outer periphery of the first magnetic element or inserted in a first central hole of the first magnetic element, so as to not only reduce the weight and spatial volume thereof, but also substantially lower the directivity of sound produced. | 10-06-2011 |
20110243370 | Loudspeaker with magnetic elements fixedly provided on diaphragm - The present invention is to provide a loudspeaker, which includes a frame having a through hole centrally provided at a bottom side thereof, a coil tube with a coil unit fixedly mounted around the outer periphery thereof and having a first end fixed to the through hole and a second end received in a receiving space of the frame, a diaphragm attached to periphery of an opening of the frame, and a plurality of oppositely oriented magnetic elements fixed on the diaphragm, wherein every two adjacent magnetic elements are spaced apart by an appropriate distance, and the magnetic elements are located in the coil tube at positions that magnetic lines generated by the coil unit are highly concentrated. Since vibration of the magnetic elements caused by the magnetic forces generated from the coil unit is enhanced, output power of the loudspeaker will increase accordingly. | 10-06-2011 |
20110274876 | Three-dimensional board structure and method for making the same - The present invention is to provide a three-dimensional board structure and method thereof by sequentially coating an adhesive on a plurality of veneers containing plant fibers, sequentially bonding the veneers together to form a multilayer board, penetrating and pressing the multilayer board by using a plurality of spikes arranged on a tool for deforming and breaking the plant fibers around peripheries of penetrated portions of the veneers, and removing the spikes from the multilayer board, such that the plant fibers around the peripheries of the penetrated portions of any two adjacent veneers are entangled with each other to form three-dimensional connecting portions in the multilayer board. Since the adhesive will permeate into the three-dimensional connecting portions due to penetration of the spikes and pressure of the tool, the three-dimensional connecting portions between the adjacent veneers and the adhesive permeated therein make the multilayer board having a three-dimensional bonding strength accordingly. | 11-10-2011 |
20120321847 | THREE-DIMENSIONAL BOARD STRUCTURE AND METHOD FOR MAKING THE SAME - The present invention is to provide a three-dimensional board structure and method thereof by sequentially coating an adhesive on a plurality of veneers containing plant fibers, sequentially bonding the veneers together to form a multilayer board, penetrating and pressing the multilayer board by using a plurality of spikes arranged on a tool for deforming and breaking the plant fibers around peripheries of penetrated portions of the veneers, and removing the spikes from the multilayer board, such that the plant fibers around the peripheries of the penetrated portions of any two adjacent veneers are entangled with each other to form three-dimensional connecting portions in the multilayer board.
