Embodiment 1

[0027] Such as figure 1 As shown, a fun speaker includes a box body 1 spliced ​​by plate-shaped bodies, and is characterized in that: the box body 1 is provided with a function amplification device 4, and the function amplification device 4 is provided with an audio output port 5; a coil 3 is fixed on either side of the box body 1, and the two ends of the coil 3 form an audio line 2, and the audio line 2 is connected to the audio output port 5, and the box body 1 is provided with A magnetic body 6 is provided on the surface of the coil 3 , and the magnetic body 6 and the coil 3 are respectively located inside and outside the box 1 and correspond to each other.

[0028] The thickness of the plates spliced ​​into the box body 1 is 2.5 mm.

[0029] The material of the plate-like body that is spliced ​​into the box body 1 adopts iron plate (also can adopt the metal plate such as copper plate, and the material of sheet material can also select hardwood board, composite board, plas...

Embodiment 2

[0036] Such as figure 1 As shown, a fun speaker includes a box body 1 spliced ​​by plate-shaped bodies, and is characterized in that: the box body 1 is provided with a function amplification device 4, and the function amplification device 4 is provided with an audio output port 5; a coil 3 is fixed on either side of the box body 1, and the two ends of the coil 3 form an audio line 2, and the audio line 2 is connected to the audio output port 5, and the box body 1 is provided with A magnetic body 6 is provided on the surface of the coil 3 , the magnetic body 6 is located on the same side of the box 1 as the coil 3 , and the magnetic body 6 is attached to the coil 3 .

[0037] The thickness of the plates spliced ​​into the box body 1 is 2.5 mm.

[0038] The material of the plate-like body that is spliced ​​into the box body 1 adopts iron plate (also can adopt the metal plate such as copper plate, and the material of sheet material can also select hardwood board, composite board...

Embodiment 3

[0043] The difference from Embodiment 1 or 2 is that the thickness of the boards spliced ​​into the box body 1 is 5 mm.

[0044] In this embodiment, the plate thickness of 5 mm is selected, and the sound emitted by the entire speaker is relatively weak, but the technical effect of the present invention can also be achieved.

Abstract

The invention discloses an interest sound box, belonging to the technical field of science exhibits. The interest sound box provided by the invention comprises a box body formed by splitting tabular bodies, wherein function amplifying equipment is arranged in the box body, and an audio output is formed in the function amplifying equipment; a coil is fixed on any surface of the box body, audio cables are formed at the two tips of the coil, and the audio cables are connected on the audio output; a magnet is arranged on the surface of the box body provided with the coil, the magnet and the coil are respectively located inside and outside the box body and correspond to each other, or the magnet or the coil is located on the same side of the box body, and the magnet is adhered to the coil. When the magnet is placed on the coil, the sound box makes a sound, and the sound stops after the magnet is taken away. According to the interest sound box, based on the requirements of science exhibits, an exhibit capable of intuitively demonstrating the operating principle of a loudspeaker with a simple structure can be provided; and the sound box has investigation and interest.

Description

technical field [0001] The invention relates to a science popularization exhibit, in particular to an interesting sound box. Background technique [0002] With the development of society, the country pays more and more attention to the cultivation of national scientific literacy. Science and technology museums, mobile technology caravans, and primary and secondary school campuses are all good science education bases. The important organizational elements of these science popularization bases are popular science exhibits. As a popular science exhibit, in addition to explaining the scientific principles well, it should also be interesting and exploreable, so as to attract people's attention and stimulate people's interest in science. [0003] With the development of science and technology, all kinds of advanced speakers have penetrated into thousands of households. The structure and principle of these mature speakers are very complicated, and it is generally difficult for non-...
