[ detailed description ] embodiments

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 to 4, the present invention provides a spiral directional separation sound structure 100 with small cavity.

In the embodiment of the present invention, the spiral directional separation sound structure 100 with small cavity includes a temple 10, a temple cover 20, a speaker 30 and a speaker holder 40.

Specifically, a sound transmission cavity 11 is arranged in the glasses leg 10, the upper surface of the sound transmission cavity is in an open state, a spiral structure 12 for separating sound is arranged on the bottom wall of the sound transmission cavity 11, a main sound outlet 13 and an auxiliary sound outlet 14 are arranged on the side wall of the sound transmission cavity 11, the horn fixing seat 40 is mounted on the spiral structure 12, a first sound outlet 41 is arranged on the side, away from the spiral structure 12, of the horn fixing seat 40, a second sound outlet 42 and a third sound outlet 43 are arranged on the side, close to the spiral structure 12, of the horn fixing seat 40, the horn 30 is mounted in the horn fixing seat 40, the glasses leg cover 20 is covered on the glasses leg 10, a low sound outlet 21 is arranged at one end of the glasses leg cover, the first sound outlet 41 is directly communicated with the main sound outlet 13, the second sound outlet 42 is communicated with the auxiliary sound outlet 14 through the cavity of the spiral structure 12, the third sound outlet 43 is communicated with the bass sound outlet 21 after passing through the cavity of the spiral structure 12 and the sound transmission cavity 11 in sequence.

It can be understood that, when the speaker 30 operates, the sound emitted from the rear cavity of the speaker 30 passes through the first sound outlet 41 and the main sound outlet 13 in sequence and is then emitted, a part of the sound emitted from the front cavity of the speaker 30 passes through the second sound outlet 42, the cavity of the spiral structure 12 and the auxiliary sound outlet 14 in sequence and is then emitted, and another part of the sound passes through the cavity of the spiral structure 12, the sound transmission cavity 11 and the bass sound outlet 21 in sequence and is then emitted.
