Description

A curved arc speaker

[Technical Field]

The invention relates to the field of sound boxes, and more particularly to a sound box with a circular arc shape. 【Background technique】

I have applied for a circular arc speaker, application number 201220484253.7, including a housing composed of a face shell, a rear case and a bottom case, and a speaker, a circuit board, a battery, an audio line, an audio plug, and the like mounted in the case. In the invention, the face shell and the back shell are arranged in a circular arc shape, and the circle corresponding to the circular arc shape has a convex structure and gradually protrudes inward from the edge, so that the face shell and the rear shell are fixedly connected to form a cavity with a bottom end opening. The bottom case is disposed corresponding to the opening shape and closes the opening, thereby forming a housing having a lower end and a lower end, and the speaker device is mounted at the lower end of the housing, thereby significantly reducing the space for the device to be placed at the upper end of the speaker, and The elliptical shape of the opening greatly reduces the space at the lower end of the speaker, so that material saving and portability can be achieved to a certain extent. Although the space inside the upper housing of the speaker is already small, there is still a lot of space in the spare space, so there is still a certain waste; the circular arc speaker only reduces the volume of the speaker to a certain extent and is convenient to carry. However, it is not practical to carry it easily, so there is still room for improvement.

【detailed description】

The invention will now be further described with reference to the drawings and preferred embodiments.

The present invention discloses a circular arc speaker, as shown in FIG. 1 to FIG. 4, comprising a housing having a small upper end and a large lower end, and a speaker device mounted in the housing, wherein the housing is provided with a hole 1 therein. A hole 1 is arranged in the housing to facilitate carrying; since the hole 1 is convenient for people to take or wear elsewhere or to place a hook or the like thereon, the circular arc speaker can be hung through the 1 hole. Place it somewhere, which is convenient for the speaker to be placed. In addition, the hole 1 is placed on the housing to make reasonable use of the space of the arc-shaped speaker for easier carrying and use.

In this embodiment, the housing includes a surface shell, a rear shell fixed to the surface shell by screws, and a bottom shell respectively connected to the surface shell and the rear shell. The three shells are fixedly connected to form a small upper end and a large lower end. a casing having a circular arc shape, wherein the face shell and the rear shell are all arranged in a circular arc shape, and the shell shell and the rear shell circle The circle corresponding to the arc has a convex structure and gradually protrudes inward from the edge; the speaker device is mainly mounted at a lower end fixed in the casing.

As shown in FIG. 1 , the housing is provided with a hole 1 which penetrates the face shell and the back shell. The arrangement is mainly for the convenience of production and for people's use habits, so that it is convenient for people to carry through the hole. the goal of. Since the upper and lower ends of the housing are large, the speaker device is mainly installed at the lower end of the housing. To ensure the stability of the arc-shaped speaker during the placement process and the robustness of the speaker device installation, the hole 1 is placed at the upper end of the housing. This makes it reasonable to use the space of the arc-shaped speaker to further facilitate the use and carrying. In addition, the above settings also make the arc-shaped speaker overall more beautiful.

In the present embodiment, the hole 1 is set as a circular hole, that is, the circular hole 2. As shown in Fig. 2 and Fig. 3, the circular hole is more convenient for use and carrying, and is easy to manufacture and produce. The circular hole 2 includes a face shell circular hole 2 of a face shell portion and a rear shell round hole 2 of a rear shell portion, and the face shell round hole 2 is at a joint of the face shell round hole 2 and the rear case round hole 2 A rim of the shell is provided at the edge, and an outer diameter of the rim of the shell is smaller than an outer diameter of the edge of the circular hole 2 of the shell, and a rim of the rear shell is provided with a rear shell 4 The inner diameter of the rear shell flange 4 is larger than the inner diameter of the edge of the rear shell circular hole 2, and the rear shell flange 4 is sleeved on the surface shell flange 3, so that the surface shell convex edge Forming a shell recess at three places, and forming a recess at the rear shell flange 4, the rear shell flange 4 is sleeved on the face shell flange 3, the rear shell flange 4 and the surface The shell recess is in close contact, and the face shell projection 3 is in close contact with the back shell recess to form a complete circular hole 2.
