Full acoustic horn and method for producing same

Abstract

The invention relates to speaker systems for high-quality sound reproduction. It provides a simplified structure of the device, improves the device manufacturability and durability. The speaker system includes the driver, the horn for reproducing low-frequency range sound (rear horn), and the horn for reproducing high-frequency and mid-frequency range sound (front horn); both horns are made in the form of a single enclosure with the capability of mounting the driver in this enclosure, while the enclosure is made of two solid parts symmetrical with respect to the plane of the central vertical section, each part represents a half of the overall profile of the front and rear horns, with no joints at the junction between the front and the rear horns.

Claims

1. Acoustic horn that includes a driver consisting of at least a diaphragm, a diaphragm suspension and a driver basket, and an enclosure in the form of a contour flaring according to a calculation, consisting of a throat, an aperture and a mouth, characterized in that the driver basket is installed in an area of the throat in a seat formed by a protrusion on an inner surface of the enclosure, while a compensating element is installed over the driver basket, which restores a profile of the horn in the area of the throat, wherein the profile formed by the enclosure is broken by the protrusion serving as a driver mounting seat.

2. Acoustic horn defined in claim 1, characterized in that the compensating element is made in the form of a ring having a three-sided shape in section, formed by two straight sides connected at right angle and one curvilinear side calculated in accordance with the profile of the horn.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

(8) The speaker system includes the driver 1, and the horn 3 located on the back side 2 of the driver 1 for reproducing low-frequency range sound (rear horn 3) in the form of a contour flaring according to the specified calculation, consisting of an inlet opening (throat) 4, aperture 5 and outlet opening (mouth) 6. The speaker system additionally includes a horn 7 to amplify sound in high-frequency and mid-frequency range (front horn 7), both horns 3 and 7 are made in the form of a single enclosure 8 with the capability of mounting the driver 1 in this enclosure 8 in the seat 9 provided for this.

(9) Seat 9 for mounting the driver 1 is made on the side of the front horn 7, it is located directly in the throat 10 of the front horn 7, while the driver 1 is installed in the area between the throat 10 of the front horn 7 and the throat 4 of the rear horn 3, so that the diaphragm 11 of the driver 1 faces the front horn, and the back side 2 faces the rear horn 3.

(10) The enlarged drawing of the speaker system unit—an acoustic horn (front horn)—is shown in FIG. 5.

(11) The acoustic horn includes the driver 1 consisting of at least the diaphragm (membrane) 11, the suspension 12 of the diaphragm 11 and the basket 13 of the driver 1, and the enclosure 8 itself—the horn. Basket 13 of the driver 1 is installed in the area of the horn throat 10 in a special seat 9 formed by a protrusion on the inner surface of the horn enclosure 8.

(12) To improve the quality of sound transmission and protect the sound against distortions, the device is equipped with a compensating element 14 that restores the desired profile of the front horn 7 in the area of its throat 10, where the above said profile formed by the device enclosure 8 is broken by a protrusion serving as a seat 9 for mounting the driver 1. The compensating element 14 is made in the form of a ring having a three-sided shape in section, formed by two straight sides connected at right angle and one curvilinear side 15 calculated in accordance with the selected profile of the front horn 7. Compensating ring 14 is installed end-to-end with the perimeter of the throat 10 of the front horn 7 on top of the basket 13 of the driver 1, installed on the seat 9 for mounting the driver 1 in the device enclosure 8.

(13) The device operates as follows.

(14) The sound from the driver 1 enters simultaneously the front horn 7 and the rear horn 3. At the same time, sounds of high and midrange frequencies are transmitted from the diaphragm 11 of the driver 1 through the front horn 7, the compensating ring 14 aligns the profile of the front horn 7 in the area of the throat 10, which ensures sound transmission at high and midrange frequencies with virtually no distortions. Low-frequency sounds are transmitted from the back side 2 of the driver 1 through the rear horn 3, forming a high-quality bass sound at the output.
