The comb may be made of wood, metal, plastic, carbon graphite, graphite and composites. The metal may be steel, aluminum, stainless steel, brass, or other metals. The metal may have a plating, such as, chrome or nickel or other plating, and/or a coating, such as, Teflon or other coating. The plastic may be acrylonitrile butadiene styrene (ABS) or other plastics. The plastic may be a composite and may be glass filled. The inserts may be made of metal, such as, brass, steel, aluminum, or other metal. The reed plates and reeds may be made of metal, such as, brass or steel.
Another embodiment of the harmonica is shown in FIGS. 12-19. The harmonica 300 is similar to the harmonica 100, but the harmonica 300 uses side buttons to attach the cover to the comb. Referring to FIGS. 12 and 19, the comb 304 may include side buttons 314, 316. The cover 302 may include openings 310, 312 to engage the buttons 314, 316. The user may depress the side buttons 314, 316 in order to remove the cover 302 from the comb 304.
Another embodiment of the harmonica is shown in FIGS. 20-28. The harmonica 400 is similar to the harmonica 100, but the harmonica 400 may include a pivot and a latch to attach the cover to the comb. Referring to FIGS. 21, 22 and 27, the cover 402 may include openings 411, 413 and the comb 404 may include an opening 415. A screw 417 may be inserted through the openings and the screw 417 may engage a nut 419. In other embodiments, the screw may engage a threaded opening in the cover or the comb, and a nut may not be necessary. In order to gain access to the comb, the cover may rotate relative to the comb along a pivot point. Referring to FIG. 28, the cover 402 may rotate relative to the comb 404 on the screw 417. Thus, the user can open the harmonica by rotating the cover 402 relative to the comb 404 in order to clean the harmonica or to repair the reeds. After the user has finished the cleaning or the repairs, the user can close the harmonica by rotating the cover 402 relative to the comb 404. The comb and/or the cover may include a latch mechanism 421. For example, the comb 404 may include a protrusion 423 which may engage a protrusion on the cover 402 to provide a snap engagement. In other embodiments, the latch mechanism may be a button and opening arrangement, such as, the side button and opening shown in FIG. 12.
Another embodiment of the harmonica is shown in FIGS. 29-40. The harmonica 500 is similar to the harmonica 100, but the harmonica 500 may include two fasteners for the covers and side vents for the cover. Referring to FIG. 36, the cover 502 may include openings 511, 513 and the comb 504 may include openings 515, 517. Screws 519, 521 may be inserted through the openings and the screws may engage nuts 523, 525. Thus, the cover may be attached to the comb. In other embodiments, the screws may engage a threaded opening in the bottom cover or the comb, and a nut may not be necessary.
Referring to FIGS. 29, 34 and 35, the harmonica 500 may include side vents 530, 532. The side vents 530, 532 may be located in the cover 502 on the left side and/or right side. The side vents allow air to escape or to enter the harmonica when the harmonica is being played. Thus, the side vents may improve the sound of the harmonica. In addition, the user may decide to cover a portion of the side vent or the entire side vent to alter the sound of the harmonica. The side vents 530, 532 may have an oval shape. In other embodiments, the side vents may have the following shapes: rectangle, square, polygon, or circle. In other embodiments, the harmonica may have one vent, three vents, four vents, or more vents. The side vent may be used with the other embodiments described herein as appropriate, such as, the harmonica in FIGS. 1, 12 and 20.
Referring to FIG. 29, the user would play the harmonica 500 by blowing into the slots 552 to make the reeds vibrate or by inhaling and drawing air past the reeds and into the slots. The air exits or enters the harmonica through the openings at the rear of the harmonica and the side vents. For example, referring to FIGS. 37 and 39, when air 555 is blown into the slot 552, the air 555 moves past the reed 544 and vibrates the reed. The air 555 then exits the harmonica through the upper rear openings 588, 590, 592 and the side vents 530, 532. The air 555 may also travel around the sides 560, 562 of the comb and exit through the lower rear openings 594, 596, 598. Referring to FIGS. 38 and 40, when air 557 is drawn into the harmonica, the air 557 may enter the lower rear openings 594, 596, 598 and the side vents 530, 532 and be drawn past the reed 544 and into the slot 552. The air 557 may also enter the upper rear openings 588, 590, 592 and travel around the sides 560, 562 of the comb to be drawn past the reed 544. Thus, the side vents may improve the sound by allowing a greater amount of air to exit or to enter the harmonica as appropriate.
