Description

A 360° speaker

technical field

The utility model relates to a sound box, in particular to a 360° full-angle sound field sound box.

Background technique

The existing sound box structure is generally that the loudspeaker is installed on one side of a cuboid box body. The sounding angle of this kind of sound box will not be greater than 120°. Outside the sound coverage area is the diffraction area of the sound, and the sound effect is relatively poor. Therefore, this kind of speaker cannot imitate the omnidirectional free propagation of natural sound waves.

Utility model content

In order to overcome the above defects, the technical problem to be solved by the utility model is to provide a full-angle sound box with a simple and novel structure and an effective sound field of 360°.

The utility model is realized through the following technical solutions:

A 360° sound box, comprising a loudspeaker and a box body, the box body comprising an upper box body and a lower box body, connected by connecting rods, the speaker is installed on the upper end of the lower box body, with the front facing upward, and the lower end of the upper box body Set up sound reflectors.

According to a preferred solution of the present invention, the sound reflector includes a conical cone.

According to another preferred solution of the present invention, a ball can be arranged at the tip of the conical cone, and the ball is directly facing the center of the diaphragm of the speaker.

In addition, the box is preferably cylindrical.

In addition, the box is preferably a bamboo tube.

Preferably, the connecting rods are three bamboo poles distributed in an isosceles triangle.

The beneficial effect of the utility model is that, through the separate arrangement of the upper and lower boxes, the speaker is installed between the upper and lower boxes, the sound is emitted by the speaker, reflected by the reflector, and spreads evenly around 360°, and the sound field is circular , to achieve a better hearing effect. Especially, when the utility model adopts the bamboo tube as the box body, a section of the bamboo tube can be divided into two parts of different lengths to make the upper and lower boxes respectively, which not only makes the production simple and low cost, but also has special bamboo flavor.

Description of drawings

Fig. 1 is the sectional structure schematic diagram of a preferred embodiment of the present utility model; And

Fig. 2 is a back view of a preferred embodiment of the utility model.

Detailed ways

The specific embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the 360 ° sound box according to the utility model includes a separate upper box body 11 and a lower box body 12, which are divided into two parts of different lengths by a section of bamboo tube, connected with a connecting rod 3 between them. The lower end of the upper box body 11 is provided with a sound reflector, including ceramic cones 2 and spherical glass beads 4, facing the center of the diaphragm of the loudspeaker 5 arranged at the upper end of the lower box body. The bamboo tube inwall of lower casing is asphalt inner wall 6, and sound-absorbing cotton 7 is placed in the bamboo tube, is cement block 8 below it.

As shown in Figure 2, the connecting rods between the upper and lower boxes are three bamboo poles distributed in an isosceles triangle, which are not only stable and reliable, but also beautiful in appearance, and can be integrated with the bamboo tube box. The bottom of the lower box is provided with an audio interface 9, which can be electrically connected to the speaker 5. When the sound box works, the audio signal is input through the interface 9, and the sound is emitted by the loudspeaker 5, reflected by the ceramic cone 2 and the spherical glass bead 4 and spreads 360° around.

In this embodiment, a bamboo tube is used as the box, and a bamboo tube is divided into two parts of different lengths, which are used as the upper and lower boxes respectively. charm.

What is disclosed above is only the preferred embodiment of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, the equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
