Description

A curved arc speaker

[Technical Field]

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

I have applied for a circular arc speaker, application number 201320019329.3, the speaker includes a shell, a round hole, a battery, a bottom case, and a battery compartment disposed on the bottom case. In general, two batteries are installed in the speaker. In order to increase the playback time of the speakers, some speakers are equipped with four batteries. It is necessary to set a battery compartment with four batteries on the speaker to put the battery into the battery compartment. It is also necessary to set the battery cover for replacing and installing the battery. Since it is a battery compartment of four batteries, when the battery cover is manufactured, it is also necessary to provide a battery cover that can cover four batteries, and the battery cover is relatively large, thereby making the battery cover difficult to fix. And the fixed protection of the battery is not very good. Some speakers with four batteries only have openings for the two batteries in the battery compartment, and the other two batteries are placed at the other end through the end, the battery cover becomes smaller, and the fixing between the battery and the housing is also firm. The fixing effect on the battery is also improved, but the setting has the following disadvantages: If the other two batteries are broken in the battery compartment or stuck in the battery compartment, it is not easy to take out the battery in the battery compartment. Not easy to inspect and repair.

The buckle is used to fix the cartridge, which is convenient for installation and opening, and is fixed firmly. In addition, the two first buckles are arranged on the elastic wall for the purpose of opening the battery cover, and the first buckle can be elastically deformed by the elastic wall. Remove from the bottom case to open the battery cover.

Preferably, the bottom case is provided with a recess at an edge of the rectangular opening and at the position of the elastic wall, and the length of the elastic wall is greater than the length of the recess corresponding to the elastic wall. The recess is arranged to facilitate the operator to fasten the elastic wall by hand, thereby opening the battery cover; the length of the elastic wall is set to be larger than the length of the recess, mainly to ensure that the first card hole and the first buckle are engaged without affecting the elastic wall. Elastic shape The change causes the elastic wall, the first buckle or the recess to be damaged.

Preferably, the bottom case is provided with a recessed platform around the edge of the rectangular opening, and the recessed platform encloses an area equal to the area of the battery cover. In this way, the battery cover can be placed on the recessed platform, and the battery cover is more firmly fixed to the bottom case by the limitation of the recessed platform.

Preferably, the height of the recessed platform from the bottom surface is equal to the thickness of the battery cover. The battery cover is placed on the recessed platform to be fixed integrally with the bottom surface, so that the flatness of the bottom surface can be ensured.

In the present invention, since a battery tray is disposed on the bottom case, the battery tray can be placed with two batteries, and the battery in the battery tray and the battery in the battery compartment are electrically connected, so that the battery tray is arranged. The inner battery can be connected to the battery in the battery compartment to supply power to the arc-shaped speaker, thereby increasing the playing time; and the battery tray can be detached from the bottom case, thereby ensuring installation when the battery is installed. When the battery, circuit or other faults in the battery tray are faulty, the battery tray can be disassembled for inspection and maintenance.

【detailed description】

The invention will now be further described with reference to the drawings and preferred embodiments. The invention discloses a circular arc speaker, comprising a face shell, a round hole, a battery, a bottom case and a battery compartment for placing two batteries disposed on the bottom case, and the bottom case is further provided with a battery capable of placing two batteries and The battery tray removed from the bottom case, the battery in the battery tray and the battery in the battery compartment are electrically connected, because the battery tray can be disassembled, so that when the battery, the line or other failures installed in the battery tray fail, It is possible to disassemble the battery tray for inspection and maintenance, and it is easy to manufacture and manufacture.

As shown in FIG. 1 to FIG. 5, the battery compartment 21 has an opening at one end of the middle portion of the bottom case and is connected to one end of the battery holder 22, so that the battery compartment 21 and the battery tray 22 are integrally formed with the battery device 2; The battery is placed, and the end of the battery tray 22 connected to the battery compartment 21 is also opened. The two ends of the battery unit 2 are respectively provided with a metal card slot for placing and fixing the metal piece, and the battery in the battery tray 22 is placed in parallel with the battery in the battery compartment 21 and connected to the positive and negative electrodes and formed together with the metal piece. Loop, thus supplying power. So by setting up four batteries of the same size on the speakers, you can increase the playback time of the speakers. A strip-like projection 23 for limiting the battery is provided at a position in the middle of the battery unit 2 and parallel to the battery placement, thereby preventing the batteries from rubbing or swaying with each other to cause poor contact.

In this embodiment, two edges located at an intermediate portion of the battery tray 22 are provided with two outwardly convex protrusions, and a screw hole is respectively disposed on the two protrusions, and the battery holder 22 is fixed by screws. The bottom case 1 is fixed by screws and is easily disassembled, thereby ensuring that the battery holder 22 can be disassembled for inspection and maintenance when the battery, the line or other malfunctions in the battery unit 2 are installed.

In this embodiment, a battery cover is further disposed on the bottom case, and the battery cover closes the rectangular opening. As shown in FIG. 1, FIG. 2, FIG. 4, and FIG. 5, the outer surface of the bottom case 1 is separated from the middle portion. One end of the rectangular opening is recessed inwardly to form the battery compartment 21, the rectangular opening becomes the battery compartment of the battery compartment, and the battery cover 3 closes the rectangular opening and passes The buckle is fixed to the bottom case. The bottom case of one end of the rectangular opening is provided with a recess 7 which is slightly recessed downward for mounting and opening the battery cover 3, thereby facilitating replacement of the battery. The battery cover 3 is provided with a narrow rectangular hole corresponding to the recess 7. On the battery cover 3, the rectangular hole and the edge of the battery cover form an elastic wall 4, and the elastic wall 4 is also narrow. a rectangular shape is provided on the outer side of the elastic wall for fixing the battery cover 3, and the other end of the battery cover 3 corresponding to the first buckle 5 is provided on the battery cover 3; The two are also the second buckles 6 for fixing the battery cover 3, so that the bottom case 1 is provided with four card holes 9 corresponding to the four buckles of the battery cover, so that the buckles can be respectively placed in the card holes. It is fixed, strong, reliable and easy to install and open.
