Embodiment Construction

[0037] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.

[0038] This embodiment provides a reflection cone, see Figure 2 to Figure 5 , the reflection surface 211 of the reflection cone 21 is a curved surface obtained by rotating a part of the parabola 213 around the fixed axis 214. The fixed axis 214 passes through the focus 215 of the parabola 213 and is perpendicular to the symmetry axis 216 of the parabola 213. A part of the parabola 213 is overfixed. An intersection point 217 of the axis 214 and the parabola 213 and a portion extending in a direction away f...

Abstract

The invention discloses a reflection cone and a sound box, and belongs to the technical field of sound boxes. The reflection surface of the reflection cone is a curved surface which is formed by the rotating of a part of a parabola around a fixed axis in one circle. The fixed axis passes through the focus of the parabola to be perpendicular to the symmetric axis of the parabola. A part of the parabola passes through one intersection of the fixed axis with the parabola and extends in a direction of leaving the top point of the parabola. The reflection surface of the reflection cone enables a sound wave to be reflected to propagate outwards in the peripheral direction of the reflection surface through the characteristics of the parabola when the sound source is located at the focus of the parabola, wherein the propagation directions of sound waves on any section of the reflection cone are parallel, so a listener has the consistent hearing sense in a 360-degree range. The distortion is small, and the sound quality is good. The sound box comprises the reflection cone and a loudspeaker, and the sound source of the loudspeaker is located at the focus of the parabola. A sound hole of the loudspeaker faces the reflection cone, and a reflection region cannot form a standing wave. The distortion is small, and the sound quality is good.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a reflection cone and a sound box. Background technique [0002] With the improvement of living standards, people pay more and more attention to the fidelity of sound quality while enjoying music. Therefore, high-fidelity speaker systems are accepted by more people. At the same time, people hope to relax and cultivate their sentiments through music during their free and rest time. Large-sized speaker equipment takes up a lot of space and is inconvenient to carry. Therefore, speaker equipment that meets the small-sized listening environment or extreme environment has become everyone's favorite. Needs have promoted the development of speakers to miniaturization. [0003] The inventor found in the process of realizing the present invention that the sound waves from the speaker drive the air to vibrate the traditional sound box to transmit the sound. When in use, the listener he...
