specific Embodiment approach

[0041] Preferably, as a specific embodiment of the audio device provided by the present invention, the air-permeable dust-proof net plug 4 is a 20-40ppi (par per inch, spongy per square inch) component.

[0042] Further, as a specific embodiment of the acoustic device provided by the present invention, the primary phase guiding structure 3 is a paper circular tube phase guiding member, that is, the primary phase guiding structure 3 is a traditional phase guiding tube, but made of paper Composed of high-quality materials, paper materials are more environmentally friendly, and the manufacturing cost is not high.

[0043] Further, as a specific embodiment of the audio device provided by the present invention, the lower bottom plate 2 is screwed to the box body 1 , which facilitates the installation and replacement of the air-permeable dust-proof net plug 4 .

[0044] Further, see Figure 6 to Figure 8 , as a specific embodiment of the acoustic device provided by the present inve...

Abstract

The invention is applicable to the technical field of electroacoustic sound equipment, and provides a sound device. The sound device comprises a box body, a sound production component and a sound production cavity, wherein the sound production component is arranged in the sound production cavity; the box body is provided with a first-stage phase conduction structure and a second-stage phase conduction structure used for non-linear air conduction; the second-stage phase conduction structure is provided with a first opening and a second opening; the second opening communicates with the first-stage phase conduction structure; the first-stage phase conduction structure is arranged in a substantially vertical direction; the second-stage phase conduction structure and the first-stage phase conduction structure are substantially vertical; and the first opening and the sound production component are arranged on the two sides of the box body. The sound device provided by the invention is provided with the first-stage phase conduction structure and the second-stage phase conduction structure used for non-linear air conduction, so that phase conduction sound wave is weakened, and the sound wave and a wall surface are in a non-perpendicular incidence relation, and thus the sound device is combined with the advantages of leading phase and rear phase structures and an ABR passive vibrating diaphragm phase conduction sound box, and the influence of factors of the wall surface and a distance from the wall surface on the sound effect is reduced while a good low-frequency effect is kept.

Description

technical field [0001] The invention belongs to the technical field of electro-acoustic audio equipment, and more specifically relates to an audio device. Background technique [0002] See Figure 1 to Figure 3 , The traditional phase-guided audio structure is nothing more than the front phase, the rear phase and the ABR (Adjustabe Bass Reflex) passive diaphragm phase. The speaker with the structure of leading phase and rear guiding phase can improve the low-frequency effect, but it is more obviously affected by environmental factors, especially the distance between the speaker and the wall. Because of the reflection factor of the wall, the music effect of the speaker will be completely different. ; ABR passive diaphragm phase-conducting (commonly known as false speakers) audio, although not affected by the distance from the wall, but when the power is high and dynamic, it is easy to control the overload, the low-frequency effect is insufficient, and the music effect is diff...
