Description

Speaker structure {STRUCTURE OF SPEAKER DEVICE}

The present invention relates to a speaker structure, and more particularly, to a speaker structure with improved workability by simplifying a speaker assembly structure.

In general, a speaker refers to a device that finally outputs sound, and is strictly divided into a speaker unit and a speaker system.

Here, the speaker unit refers to a component composed of a magnet, a coil surrounding the coil, and a diaphragm. The speaker unit is divided into a tweeter speaker unit for emitting high frequency sound and a woofer speaker unit for emitting low frequency sound according to the emitted sound wave.

In addition, the speaker system is a kind of set that collects several speaker units, arranges them in a ring, and has terminals for connecting to an amplifier. The term speaker refers to such a speaker system.

In addition, home appliances in which speakers are used include home-theater, audio, TV, and the like, and recently, a speaker system capable of producing various sound field effects to provide a three-dimensional effect is provided.

Such a speaker is provided with a speaker unit such that sound waves are radiated by an operation of a diaphragm in an enclosure. The enclosure refers to a speaker case made of wood, plastic, or the like in which the unit of the speaker is assembled. The enclosure is also called a cabinet or a box. In addition, the enclosure is classified into a decorative speaker and a tall-boy type speaker according to the size and shape of the exterior.

In particular, the following two unfavorable phenomena occur when radiating sound waves by operating only the speaker unit without the enclosure. First, the bass is not played properly, and second, the sound quality is poor.

Therefore, the speaker unit is generally installed in an enclosure, and a front panel that forms the front of the speaker while supporting the speaker unit is provided at the front of the enclosure.

The speaker configured as described above is coupled to the speaker unit, the front panel and the enclosure or the main body (main body) by a large number of screws (screw) as well as by ultrasonic welding (or assembled).

However, due to the characteristics of the speaker during fastening by the screw, the screw is loosened due to vibration, or a screw fastening failure may occur, and thus the screw fastening force may drop, and in the case of ultrasonic fusion, defects such as ultrasonic non-fusion may occur.

Accordingly, if the fastening force or the coupling force is dropped or bad, the effect of the speaker is reduced, as well as a large number of assembly personnel for fastening screws or ultrasonic welding, and a special manufacturing jig is required for ultrasonic welding.

Accordingly, the conventional speaker structure is difficult to maintain a solid structure, labor costs and jig production costs a lot, product assembly time is increased, productivity is reduced, product defects are generated a lot, A / S cost, product There is a problem in that the cost is increased.

The present invention has been made to solve the above problems, to provide a speaker structure that allows the speaker structure to be firmly maintained, the tightening force is improved, and the assembly is improved to reduce product productivity and product cost. There is a purpose.

The speaker structure of the present invention for achieving the above object, the enclosure; A speaker unit installed in the enclosure; And a front cover installed at the enclosure in front of the speaker unit. In this case, a plurality of protrusions are formed on the outside of the enclosure, and the enclosure and the front cover are fixed to the edge of the front cover by being combined with the protrusion. At the same time there is provided a plurality of coupling members formed with coupling grooves for allowing the speaker unit to be fixedly installed in the enclosure,
And, the coupling member is provided to be rotated at an angle toward the upper surface of the front cover,
The enclosure may include a main body and a sub body provided in the main body and having an opening so that the speaker unit may occupy a space in the main body.

According to the exemplary embodiment of the present invention, since the assembly is performed by fitting all of the speaker parts, there is no need for a screw fastening process or an ultrasonic welding process for assembling the speaker as in the prior art.

Therefore, it is possible to reduce the number of workers for assembling the speaker, the jig for the ultrasonic welding is not required, it is possible to reduce the work defects generated during the screw fastening process or the ultrasonic welding process.

Accordingly, the conventional speaker structure can be maintained in a solid structure, can significantly reduce labor costs and jig production costs, and can reduce the product assembly time to the extent that compared to the existing productivity improves, almost no product defects As a result, after-sales cost can be reduced and product cost can be reduced.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
