Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a protection net of a speaker, and more particularly to a structure for fixing a protection net using the magnetic force of a magnet of a speaker.

[0002]

BACKGROUND OF THE INVENTION Most currently used speakers are direct radiating. In this type of speaker, a sound signal is supplied to a voice coil disposed in a gap provided in a part of a magnetic circuit, and the diaphragm is vibrated, so that sound is radiated into space. The shape of this diaphragm is roughly classified into a cone shape and a dome shape. Domed speakers are often used.

However, in the case of a dome-shaped speaker, the diaphragm is easily damaged because the diaphragm protrudes to the front of the speaker.

[0004]

Therefore, a protection net is generally provided on the front of the dome-shaped speaker, but it is necessary to fix the protection net to the front of the dome-shaped speaker. FIG. 3 is a perspective view for explaining a method of fixing a protective net which has been conventionally applied.
The protective net 12 is fixed by fitting the protection net 12 into a groove 112 provided concentrically with the groove.

[0005] Butyl rubber or an adhesive is poured into the bottom of the groove 112 to secure the protection net. When butyl rubber is used to fix the protection net 12, the protection net can be removed, but there is a problem that the butyl rubber gradually deteriorates and the fixing force is weakened.

On the other hand, when an adhesive is used, there is a problem that the protective net cannot be removed and the speaker cannot be relocated. The present invention has been made in view of such a problem, and an object of the present invention is to provide a fixing structure of a speaker protection net that can not only easily remove the protection net but also maintain the fixing.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a loudspeaker protection net fixing structure according to the present invention. A dome-shaped loudspeaker having an insertion opening penetrating through a front component of the dome-shaped loudspeaker such that the foot is in direct contact with the upper surface of the magnet.

[0008]

The protective net is fixed to the front of the speaker by inserting the feet arranged around the protective net into the notches formed in the speaker grille and making direct contact with the speaker magnet. .

[0009]

1 and 2 are a perspective view and a sectional view, respectively, of an embodiment of a protective net fixing structure according to the present invention. A dome-shaped speaker 10 has a cylindrical magnet 16 and an upper plate on a lower plate 15. 17 and the grill 11 are laminated. The lower plate 15 has a shape projecting from the center, and is inserted into the magnet 16, the upper plate 17, and the grill 11 to form a magnetic circuit.

[0010] the lower plate 15 and the dome-shaped cone 19 and winding the voice coil 18 in the gap formed between the magnet 16 and the upper plate 17 is disposed. The protective net 12 has a dome-shaped shape so as to cover the dome-shaped cone 19 and has legs 121 extending vertically around the periphery.
Having. The grille 11 and the upper plate 17 have insertion holes 1 corresponding to the feet 121 provided on the protection net 12.
11 and 171 are provided.

The insertion openings 111 and 171 pass through the grill 11 and the upper plate 17, respectively.
The feet 121 provided on the protection net 12 are magnets 16
Contact directly. Since the protection net 12 is generally made of steel, the protection net 12 can be fixed by the magnetic force of the magnet 16.

[0012]

According to the present invention, it is possible to fix the protection net by using the magnetic force of the magnet of the dome-shaped speaker. Never weaken.
