Abstract

The utility model relates a super-thin high power loudspeaker which is suitable for LED (light-emitting diode) super-thin video equipment. The super-thin high power loudspeaker comprises a magnetic return component, a basin frame, a piece of drum paper and a voice coil; wherein the basin frame is sleeved around the magnetic return component; the drum paper is arranged at the periphery of the basin frame; the voice coil is connected with the drum paper and is embedded in the magnetic return component; and an elastic ring is also arranged between the basin frame and the drum paper. The elastic ring is used for replacing elastic wave in the traditional loudspeaker and is arranged between the basin frame and the drum paper to provide a vertical expansion force, therefore, the space of the thickness is saved and the function of the elastic wave is totally replaced; therefore, the demand for bearing high power is realized; the super-thin high power loudspeaker is particularly suitable for the video product like LEDs, etc.

Description

A kind of ultrathin high power loudspeaker

Technical field

The utility model relates to a kind of loudspeaker, relates in particular to the ultrathin high power loudspeaker that the ultra-thin video equipment of a kind of LED of being applicable to is used.

Background technology

Loudspeaker claim loud speaker again, be a kind of be the electroacoustic component of sound with electrical signal conversion, mainly comprise parts such as vibrating diaphragm, voice coil loudspeaker voice coil, bullet ripple, basin frame, magnet, its sounding principle is when different electron energies reaches voice coil loudspeaker voice coil, voice coil loudspeaker voice coil produces the magnetic field interaction of a kind of energy and magnet, this interaction causes the vibrating diaphragm vibration, because electron energy changes at any time, the voice coil loudspeaker voice coil of loudspeaker can move forward or backward, therefore the vibrating diaphragm of loudspeaker will and then move, and this action changes the density degree of air and produces sound.

The mechanical type fault is one of normal fault that occurs of loudspeaker, the driving loudspeaker of excess load make vibrating diaphragm move and go beyond the scope and separate with voice coil loudspeaker voice coil, or voice coil loudspeaker voice coil separates with the voice coil loudspeaker voice coil seat, and vibrating diaphragm flanging or loudspeaker bracing ring are torn, more than the generation of arbitrary situation loudspeaker are broken down.

Loudspeaker are widely applied in the electronic products such as television set, display, notebook computer as a kind of sound-producing device, and along with the extensive use of LED technology in these fields, video equipment is constantly pursued minimal thickness, simultaneously image quality also further improves, thereby corresponding acoustical quality and power requirement also will have further lifting.The tradition loudspeaker can't meet the demands on thickness, and common improved-type thin type horn can reach the requirement of thickness, but can't reach power requirement.Therefore, industry presses for a kind of loudspeaker that satisfy the requirement of thickness and tonequality and power simultaneously.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of thin thickness, loudspeaker that power is high are provided.

For achieving the above object, the utility model adopts following technical scheme:

A kind of ultrathin high power loudspeaker, comprise magnetic return assembly, be sleeved on described magnetic return the assembly periphery the basin frame, be installed in the bulging paper on the described basin frame periphery and be connected on the bulging paper and be enclosed within magnetic and return voice coil loudspeaker voice coil in the assembly; Also be provided with the bullet circle between described basin frame and the drum paper, can be bulging paper a vertical contractility is provided.

Described magnetic returns the washer that assembly comprises U iron, is positioned at the magnet of described U iron and is installed on described magnet top.

The cross section of described basin frame is " several " word shape, forms recess and protuberance.

Described magnetic returns the protuberance in the middle of the assembly setting-in engagement frame.

Described bullet circle places the recess of basin frame.The bullet circle is the closed circle that adopts elastomeric material to make, and its cross sectional shape is similar to the runway of sports ground, comprises upper flat plate and following flat board that parallel and shape is identical with size; Also comprise the camber plate of two symmetries, two camber plates are located at the both sides of two flat boards, and an end of camber plate is fixed on the upper flat plate end, and the other end is fixed on down dull and stereotyped terminal.

The inner edge surface that described bulging paper bag is drawn together outer edge surface, is connected with outer edge surface, the inner edge surface of drum paper embeds the recess of basin frame, and the outer edge surface bridge joint is above the protuberance of basin frame.

Can connect terminal board in U iron bottom.

The beneficial effects of the utility model are: employing bullet circle substitutes the bullet ripple in traditional loudspeaker, be installed between basin frame and the drum paper, for drum paper provides a vertical contractility, reduced the generation of mechanical breakdown, saved the space of thickness simultaneously, replace playing the function of ripple again fully, realized bearing powerful requirement, be particularly suitable for LED class video product.
