Abstract

A multi-diaphragm loudspeaker relates to a loudspeaker. The voice coil loudspeaker comprises a basin frame, wherein a lower magnet is directly arranged at the bottom in the basin frame, and a washer, an upper magnet and a voice coil are sequentially stacked upwards, and at least two vibrating diaphragms are sequentially arranged on the periphery of the voice coil from bottom to top; preferably, the periphery of the voice coil is sequentially sleeved with a first vibrating diaphragm and a second vibrating diaphragm from bottom to top, and the top of the voice coil is covered with a third vibrating diaphragm; the first vibrating diaphragm, the second vibrating diaphragm and the third vibrating diaphragm respectively consist of a suspension edge and a multi-shaped body; the groove of the dangling edge of the first vibrating diaphragm and the groove of the dangling edge of the second vibrating diaphragm face upwards, the groove of the dangling edge of the third vibrating diaphragm faces downwards, and the dangling edge of the third vibrating diaphragm is attached to the body of the second vibrating diaphragm. Has the advantages that: a dustproof cap is not needed, the structure is compact, and the height of the horn is reduced; the resonance frequency point of the loudspeaker is reduced, and the bass effect is good; the distortion degree of the sound is small and vivid; the U-shaped iron is not used, so that the cost is reduced; is suitable for TV products and other portable sound products.

Description

Many vibrating membrane loudspeakers

Technical field

The utility model relates to loud speaker, refers to a kind of many vibrating membrane loudspeakers especially.

Background technology

The loud speaker of prior art comprises the basin frame, at basin frame inner bottom part U-shaped or T shape iron are installed, in U-iron, up put into successively lower magnet, washer, on magnet, voice coil loudspeaker voice coil, vibrating diaphragm, packing ring, terminal, bullet ripple and dust cap, wherein, lower magnet, washer and last magnet are bonding to each other, and voice coil loudspeaker voice coil is arranged at the pore location that plays ripple, and the mesopore of vibrating diaphragm is stretched out on the top of voice coil loudspeaker voice coil, top end cover at voice coil loudspeaker voice coil is established dust cap, and terminal is connected with the basin frame.There is following drawback at least in this structure:

1, the thickness of loud speaker is big, is difficult to slim development;

2, especially bass effect is not good enough for sound effect.

Along with the progress and development of electronic technology, TV product and other portable sound products are all developing towards more and more thinner direction.Therefore the loud speaker that uses on these products also just must design thinlyyer, to adapt to the needs of market development.Also only in this way just can make the product of enterprise in intense market competition, stand on the invincible position.Developing more super-thin speakers has been imperative for capturing following TV and sound produce market.So must comply with loud speaker thickness will approach, sound will be got well, and particularly bass effect will good development trend, develops the good loud speaker of thin thickness and bass effect.

Summary of the invention

The utility model is intended to the above-mentioned deficiency and the market demand at prior art, releases a kind of many vibrating membrane loudspeakers.Its thin thickness, sound is good, and particularly bass effect will be got well, and is suitable for TV product and other portable sound products and uses.

To achieve these goals, the many vibrating membrane loudspeakers of the utility model adopt following technical scheme:

Structure the utility model many vibrating membrane loudspeakers comprise the basin frame, and lower magnet is directly installed in the bottom in the basin frame, more up successively the closed assembly washer, go up magnet and voice coil loudspeaker voice coil, the periphery of voice coil loudspeaker voice coil sets gradually at least two Zhang Zhen's films from bottom to top.

Technique scheme is further set forth:

Sheathed successively from bottom to top first vibrating diaphragm of the periphery of voice coil loudspeaker voice coil and second vibrating diaphragm are established the 3rd vibrating diaphragm in the top cover of voice coil loudspeaker voice coil again.

First vibrating diaphragm, second vibrating diaphragm and the 3rd vibrating diaphragm are made up of the trunk of outstanding limit and multiform shape respectively.

The chase on the outstanding limit of the chase on the outstanding limit of first vibrating diaphragm and second vibrating diaphragm up, the chase on the outstanding limit of the 3rd vibrating diaphragm down, and the outstanding limit of the 3rd vibrating diaphragm is fitted on the trunk of second vibrating diaphragm.

Bonding terminal is to insert signal on the basin frame.

Lower magnet is adhered to the bottom in the basin frame, and lower magnet, washer and last magnet are mutually bonding each other.

Compare with prior art, the beneficial effects of the utility model are: one, adopt many diaphragm structures, and the many trunks in promptly many outstanding limits, without dust cap, compact conformation reduces the height of loudspeaker; Its two, the resonant frequency point of loud speaker is reduced, bass effect is good; Its three, the distortion factor of sound is little, and is true to nature; Its four, adopt lower magnet, washer and go up the magnetic circuit of magnet, select the strong magnetic of neodymium iron boron for use, also be beneficial to the height that reduces loudspeaker; Without U-iron, cost is reduced; Its five, be suitable for TV product and other portable sound products and use.
