Problems solved by technology

[0003] Is there any kind of speaker design that can be compatible with the design that does not need to pay attention to the volume, the speaker is opened in the same direction as the guide hole (front opening), and no need to add wave-absorbing materials to perfectly present the midrange and bass?

Embodiment 1

[0018] Such as figure 1 As shown, a sound box has a total height of 285 mm inside the box body 1, an internal total width of 155 mm, and an internal depth of 95 mm. The outside of the casing 1 can be shaped arbitrarily. A woofer opening 2 is provided at the front center of the box body 1 with a diameter d of 95 mm. A sound guide hole 3 is provided below the woofer opening 2 . The center of the sound guide hole 3 is 47.5 mm from the inner bottom plate of the box, and the diameter of the sound guide hole 3 is 19 mm 20%. The turning points of adjacent two or more sides of the internal structure of the box body 1 cannot be at right angles or acute angles, and are preferably arc turning surfaces to eliminate audio standing waves. The aperture of the sound guide hole 3 is allowed to have a plus or minus error of 20%.

Embodiment 2

[0020] Such as figure 2 As shown, the sound guide hole 3 is arranged above the woofer opening 2, and the center of the sound guide hole 3 is 47.5 mm away from the top plate. Others are with embodiment 1.

Embodiment 3

[0022] When the inner width of the cabinet is 285 mm, the sound guide hole 3 is arranged on the left side of the woofer opening 2, and the center of the sound guide hole 3 is 47.5 mm away from the left side. Others are with embodiment 1.

Abstract

The invention provides a sound box. The height of a box body of the sound box is 3d, the width is (d + 6cm)-3d, and the depth is d; the center of the front surface of the box body is provided with a woofer opening, and the diameter of the woofer opening is d; and a sound guide hole is arranged above or below the bass horn opening. The distance between the center of the sound guide hole and the center line of the top plate or the bottom plate is 1 / 2d, and the sound guide hole diameter is d / 520%. The mounting position of the mid-bass horn or the full-frequency horn is crucial, the mid-bass hornopening or the full-frequency horn opening is formed in the center of the front face of the box body, the echo hole is formed in the position 1 / 2 d away from the center line of the top plate or the bottom plate, and the effects of stronger sound production than the horn, namely full bass and male alto can be achieved. The low sound can be heard by human ears and is not distorted.

Description

technical field [0001] The invention relates to musical equipment, in particular to a sound box. Background technique [0002] Speaker design is ever-changing, theories involve a wide range, and the effects presented are also varied; but in general, speaker design mainly solves the problem of bass presentation. The treble and midrange are presented directly by the speakers. In reality, the woofer still needs to present a certain midrange, so the speaker needs to solve the problem of perfect presentation of the bass and midrange. Furthermore, the design of the speaker must pay attention to the seamless connection of the midrange and bass while the bass is exposed from the cabinet; and the influence of standing wave effects such as refraction, diffraction, and scattering of the bass and midrange in the cabinet. Otherwise, the performance of the midrange and bass will be distorted (the box will be stuffy), the midrange and bass will be out of touch, and there will always be s...
