| 20090249627 | METHOD OF MANUFACTURING LAMINATED DAMPING STRUCTURE WITH VULCANIZED RUBBER AS VISCOELASTIC CORE - The present invention provides an improved method of manufacturing constrained layer dampers with a vulcanized rubber viscoelastic core. The method includes the steps of: applying a first layer of adhesive to a first constraining layer; applying a layer of unvulcanized rubber solved in a solvent to the first layer of adhesive to form a first laminate structure; applying a second layer of adhesive to a second constraining layer to form a second laminate structure; laminating the first laminate structure with the second laminate structure; coiling the laminated first and second laminate structures; and increasing the temperature of the coiled first and second laminate structures to thereby vulcanize the layer of rubber. | 10-08-2009 |
| 20140013601 | METHOD FOR MAKING ACOUSTIC HONEYCOMB - A method for making an acoustic structure that includes a honeycomb having cells in which septum caps are located. The septum caps are formed from sheets of flexible material that may be perforated before or after the material is inserted into the honeycomb. The flexible material is sufficiently flexible to allow folding into the shape of a septum cap. The flexible material is also sufficiently stiff to provide frictional engagement and locking of the septum cap to the honeycomb cell when the cap is inserted into the honeycomb during fabrication of the acoustic structure. An adhesive is applied to the septum caps after the caps have been inserted into the honeycomb cells to provide a permanent bond. | 01-16-2014 |
| 20140068944 | SYSTEMS AND METHODS FOR ASSEMBLING NON-OCCLUDING EARBUDS - Systems and methods for assembling non-occluding earbuds are disclosed. The earbud includes a non-occluding housing having a directional sound port offset with respect to a center axis of the earbud. The housing can have an asymmetric shape amenable to in-the-ear retention. Additionally, the housing can have a seamless or nearly seamless construction even though two or more parts are joined together to form the housing. | 03-13-2014 |
| 029896210 | Hearing aid component making | 1 |
| 20080301944 | HEARING DEVICE WITH EMBEDDED CHANNEL - A hearing device having at least one of an acoustical/electrical converter and an electrical/acoustical converter respectively with an acoustical input or output. The input or output, as the case may be, is linked to a coupling opening at the outer surface of the device via a channel. At least a part of the outer surface of the device is formed by a one-part shell. The shell defines an inner space of the device, with the channel being provided within and along the part of the shell and being formed within the material of the shell. | 12-11-2008 |

| 20130111757 | METHOD OF FABRICATING BOW STICK OF STRINGED INSTRUMENTAND BOW STICK OF STRINGED INSTRUMENT - A method of fabricating a bow stick includes winding a prepreg, in which a fiber is impregnated with a resin, on a mandrel with a diameter gradually decreasing toward a distal end, setting a semi-fabricated product, in which the prepreg is wound on the mandrel, into a mold and molding the semi-fabricated product in a shape corresponding to a cavity formed between the mold and the mandrel by heating and pressurizing the semi-fabricated product in the mold, and taking out the mandrel from a molded product molded in the shape corresponding to the cavity to acquire a long and hollow stick body. When adjusting at least one of a weight distribution, a center of gravity, and a weight of the stick body, the volume of the cavity is changed using the mandrel of which the diameter or the diameter variation is gradually changed in an axis direction. | 05-09-2013 |
| 20130318794 | Method of Coupling Diatonic Harmonicas - A method of coupling diatonic harmonicas that increases the musical range of the diatonic harmonicas being coupled. Diatonic harmonicas are stacked and secured together by a clamping mechanism in order to form an instrumental assembly that is more versatile than a single diatonic harmonica. An ideal key is first determined according to a selected musical piece. The ideal key provides a foundation from which an initial harmonica and a subsequent harmonica are selected from a plurality of harmonicas. Each of the plurality of harmonicas is tuned in a musical key that is either major or minor. The musical key of the initial harmonica is determined according to the ideal key, while the musical key of the subsequent harmonica is determined from the chromatic scale. Once the initial harmonica and the subsequent harmonica are selected, they are coupled together by the clamping mechanism. | 12-05-2013 |
| 20140298654 | VERTICAL SIDES BANJO TONE RING AND METHODS - The present invention is a banjo tone ring with vertical sides ( | 10-09-2014 |
| 20150107112 | METHOD OF RETROFITTING A HARMONICA - A harmonica with a tube plate that provides production of sweeter, clearer notes with a minimum of skill. The tube plate has a plurality of tubes and sits over the reeds and the comb under the cover plate, a tube coupled with each air chamber in the comb. The tubes form tunnels with the air chambers, enhancing reverberation and separating the sound waves emanating from the reed in each chamber. The tube plate can be added to a conventional harmonica. The harmonica has a plurality of reed units, each reed in a separate unit. Each reed unit is individually replaced when a reed requires replacement or when modification of the harmonica key is desired. The reed units can replace a reed plate in a conventional harmonica. | 04-23-2015 |

| 029896230 | Including diaphragm or support therefor | 1 |
| 20160088412 | METHOD OF MANUFACTURING DIAPHRAGM - The present disclosure illustrates a diaphragm and manufacturing method thereof. The diaphragm includes a ring-like diaphragm edge made of metal material and a diaphragm film formed by graphene film plate. The diaphragm film is fixedly connected with an edge of the diaphragm. The present disclosure uses the metal ring and the graphene film to form the diaphragm, to increase sensitivity and strength of the diaphragm. At the same time, the diaphragm of the present disclosure can meet the requirement for minimized manufacturing by utilizing manufacturing processes of CVD, PVD, exposure, and development. | 03-24-2016 |
