DETAILED DESCRIPTION

(11) For descriptive purposes, the invention relates to the construction of an electric guitar, without this limiting the scope of the invention, since it can be applied to any stringed musical instrument.

(12) As shown in FIGS. 1, 3 and 4, the unitary structure (40) incorporates all the basic elements of a guitar or similar instrument; including body (15), neck (41) and head (17), minus the strings, the tuning pegs, the fingerboard, the bridge and any desired electronic means.

(13) The body (15) of the guitar preferably comprises a distinctive pattern of cavities (24) and/or housings (37) in its front part (43) placed in predetermined locations and intervals and open chambers (29) extending between said front part and the rear part (42). This preferred arrangement reduces the total body weight while maintaining the required structural strength.

(14) At least some of said cavities (24) and/or housings (37) are communicated internally by openings arranged in the side walls thereof forming an interconnected network that allows to control the resonance and sustain within the structure of the integrally formed body.

(15) The open chambers (29) are delimited by at least some internal ribs (28).

(16) The body (15) further comprises projections (27) in one of the housings (37) for the mounting of pickups (5).

(17) The neck (41) is formed as an open frame including hollow cavities in its front part delimited by a side wall (39), a bottom wall (38) and a central rib (26). It is contemplated that said cavities may accommodate optical fibers or resins connected to light emitting diodes (LEDs), visible through one or more light ports (3,47) located on the front of the fingerboard (2).

(18) The neck is provided with fixing means (25, 36) for fixing the fingerboard (2).

(19) The head (17) is provided with holes (44) for mounting tuners (19) with their corresponding pegs.

(20) Additionally, it is contemplated that the optical fibers or resins extend to a housing (34) located on the back of the head (41), which in turn serves to reduce the weight of the instrument, and are visible through a light port (1) located on the front thereon. The housing (34) is sealed by a back cover (18).

(21) In another embodiment, it is contemplated that the front part (43) of the instrument includes a touch screen.

(22) FIG. 3 shows the back of the guitar including a housing (45) for housing the structure of a tail piece (9), the latter included integrally in said body (15), and a housing (46) equipped with supports (30) that are an integral part of the unitary structure and are intended to support a power source.

(23) FIG. 4 shows the unitary structure (40) with front panels (13A, 13B, 13C) that frontally seal the body (15) and are connected to said body through connection means (14). The front part (43) includes a bridge (6) also manufactured by CNC, preferably in aluminum, pickups (5) mounted on one of the front panels (13B) and supported by the projections (27) and electronic means (10, 11 and 12) mounted on one of the front panels (13C).

(24) FIGS. 5 and 6 show a front view of two embodiments of the fingerboard (2, 2′). Said fingerboard includes a front surface (35) with a compound radius (2A-2B, 2′A-2′B) that offers multiple possible combinations, an associated set of frets (31) integrally configured with said front surface and comprising a zero-fret (33) and a zero-fret guide (32). Additionally, the fingerboard (2, 2′) is provided with connection means (16, 25) for the removable connection of the fingerboard to the neck (41).

(25) In an alternative embodiment, it is contemplated that the fingerboard-neck connection be made by magnet-type connection means.

(26) FIG. 8 shows a rear view of the instrument with rear panels (21A, 21B) which subsequently seal the body (15) and are connected to said body through connection means (22).

(27) In an alternative embodiment, it is contemplated that the connection means (14, 22) of the front and/or rear panels is made by magnet-type connection means.

(28) The structure formed integrally is produced from a solid block of non-wood material by computer numerical control (CNC) that allows the production of structures of high precision and quality.

(29) The fingerboard is manufactured with the frets mechanized under CNC integrally with the rest of the structure of the fingerboard from a single block of rigid material, preferably aluminum.

(30) Once the nature of the invention has been sufficiently described, as well as some examples of preferred embodiments, it is stated for the appropriate purposes that the materials, form, and size of the elements described may be modified, provided that this does not involve an alteration of the essential features of the invention that are claimed below.
