Description

[0011] The drawings accompanying the invention illustrate the following, in brief:

[0012] Drawing 1 illustrates the present inventive idea by the front view, with two loudspeakers and two openings as well as the detachable covers of the openings (FIG. 1a). It also illustrates a variation of the present inventive idea by the front view, with one loudspeaker and one opening as well as one removable cover of the opening (FIG. 1b). It also illustrates a variation of the present inventive idea shown in FIG. 1b, with one loudspeaker, which is positioned in the center of the front view and one opening and the removable cover of the opening, with special bridge securing the bridge of the strings (FIG. 1c).

[0013] Drawing 2 illustrates the interior of the invention and its electrical components, namely, the loudspeakers, the preamplifier with amplifier without the “vessel” (back cover) of the instrument and the output to the console (FIG. 2a). Illustrates even the above-mentioned parts with the “vessel” of the instrument when the preamplifier with amplifier are placed in an alternative position to the side of the vessel, always in such a way in order for the user to have access to the setting buttons (FIG. 2b).

[0014] Drawing 3 illustrates the front view of the invention, in variations without loudspeaker, with small openings and removable covers (FIG. 3a), with smaller openings (FIG. 3b) or less openings (FIGS. 3c and 3d) and removable covers and without any openings (3e).

[0015] Drawing 4 illustrates the back view of the “vessel” of the invention in variations with four openings and the removable covers in plan view (FIG. 4a) and side view (FIG. 4b) and with one opening and with the removable cover in plan view (FIG. 4c) and side view (FIG. 4d).

[0016] Drawing 5 illustrates in plan view the back of the “vessel” of the invention in variant with more openings (FIG. 5a) and the removable covers (FIG. 5b).

[0017] Following there is an example of an application of the present invention referring to the accompanying drawings:

[0018] As illustrated in drawings 1 and 2, the electroacoustic bouzouki, like all corresponding instruments of current state of the art, bears, in principle, neck (1), which as it happens in all electrical instruments (electric guitar, electric oud, etc.) reaches the tailpiece (2). The neck (1) on the end bears head (3) with tuning keys which tighten and secure the strings (4), carries electromagnet (5) (pickup) and bridge (6) over which the strings pass (4) and continue and fix in the tailpiece (2).

[0019] Besides all the above components, which as stated above exist in all bouzouki, the electroacoustic bouzouki further bears piezoelectric component (8) on the front (7) and mounted inside the bridge (6), for generating and shaping the electrical sound (FIGS. 1a, 1b, 1c). In the inside (FIG. 2) the electroacoustic bouzouki bears preamplifier (9) and amplifier (10) and at least one loudspeaker (11) with exit to the front view (7) of the instrument (FIG. 1b), as it can bear two loudspeakers placed symmetrically (FIG. 1a) or more loudspeakers. When the front view (7) has a loudspeaker (11) in the center (FIG. 1c), special mounting bridge (15) is used for supporting the bridge (6) which supports the strings (4), (FIGS. 1,2).

[0020] The loudspeaker (11) may be of high or low intensity at the option of the user, because placing it on the instrument intends to offer the user natural familiarity with the sound of a loudspeaker, without the need of using a separate amplifier or microphone installation.

[0021] To be able to connect to microphones, electroacoustic bouzouki also bears output (12) of electrical signal to the console. Finally it bears battery (16) for the power supply, which may be in the interior of the instrument (FIG. 2b) or can be externally and the instrument simply has a socket for connection to the battery.

[0022] Also, through the openings (13) of the vessel the user has access to the preamplifier (9) and amplifier (10) and regulates them by the available buttons (Drawing 2 FIG. 2b).

[0023] The electroacoustic bouzouki may not bring any loudspeaker in his body. Thus, as illustrated in Drawing 3, the front view (7) of the instrument, may have openings (18), small (FIG. 3a), smaller (FIG. 3b) or fewer (FIGS. 3c and 3d), in all cases with removable covers (17), or may not have any opening (FIGS. 3d). The size of the openings (18) and their number determine the intensity and configuration of the produced natural sound. In case the electroacoustic bouzouki bears no loudspeaker in its body, the existence of a preamplifier (9) is optional, mainly for reasons of cost, and the output of electric sound, for the microphone system is done either with the function of the electromagnet (5), or the piezoelectric component (8) disposed on the saddle (6) or by the combined operation of the two components.

[0024] In case of operation out of an electric network and without battery (16), the electroacoustic bouzouki always produces a natural sound, which is indeed lower in intensity of the natural sound produced by the traditional bouzouki, but is always greater than the sound produced by a soundless bouzouki. This is because if the instrument has openings in the front view (7), these are always of small size (Drawings 1 and 3) and arrive to be zero (FIG. 3e).

[0025] Drawings 4 and 5 illustrate the rear part “vessel” (13) of the invention, which in each case has at least one opening of any shape. In the examples of the inventive idea illustrated in Drawings 4 and 5 openings (19) are one opening (19) (FIGS. 4c and 4d), four openings (19) (FIGS. 4a and 4b) and six openings (19) (FIGS. 5a and 5b). For each opening there is removable cover (14) of corresponding shape.

[0026] The same inventive concept can be applied when the “vessel” of the electroacoustic bouzouki carries less or more openings, symmetrically or not, and of any shape. The removable covers of the openings adapt the instrument to the needs of each user, meaning that the addition of the covers and the closing of the openings leads to the production of stronger natural sound by the instrument, whereas the removing of the covers leads to the production of weaker natural sound.

[0027] The vessel (13) is mounted on the front part (7) of the instrument by screwing or gluing. The vessel (13) is preferably made of plastic material, but can also be of wood or light metal (e.g. aluminum). The covers (14) of the vessel (13) are preferably made of plastic material.

[0028] The covers (17) of the openings (18) of the front part (7) are preferably made of plastic material but they can also be made of any other material (e.g. wood, light metal, etc.). All covers (17) (14), of the front part (17) and vessel (13) (14) may bear decorative elements and serve as decoration of the instrument.

[0029] The perforated vessel (13), which is preferably made of plastic, keeps the shape of the vessel of the traditional wooden vessel while the openings do not affect the stability of the instrument regarding the grip and the handling by the musician. The maximum operational use of electroacoustic bouzouki with perforated vessel (13) is achieved when the vessel (13) has between four to six openings (19), as illustrated in FIGS. 4a and 5a.

[0030] The piezoelectric (8) component for the producing of the electric sound can operate alone or in conjunction with the electromagnet (5), and the electromagnet (5) can operate without the amplifier (10) and the preamplifier (9).

[0031] The present invention finds application as a musical instrument, which is used to perform music compositions both with natural, and electric sound.
