Embodiment

At electronic product gradually under the trend of downsizing, be installed in the also necessary microminiaturization of each accessory size in the electronic installation, with loudspeaker arrangement, because traditional loudspeaker arrangement has the design of audio amplifier, often because volume is excessive and inapplicable in electronic product now, but if exempted the design of audio amplifier, the problem that then has soundproof effect variation, the mutual interference of sound wave phase or the like again produces.Therefore, the utility model proposes a kind of shockproof loud speaker, below, execution mode of the present utility model and accompanying drawing provided simultaneously, so that the major technique feature of shockproof loud speaker of the present utility model to be described.

At first, please refer to Fig. 3 and shown in Figure 4, wherein, Fig. 3 is the perspective view of shockproof loud speaker provided by the utility model, Fig. 4 is the cross section structure schematic diagram of the shockproof loud speaker of Fig. 3, comprise a loudspeaker monomer 20 at shockproof loud speaker 60 of the present utility model, loudspeaker monomer 20 peripheries are then encircled and are established an outer suspension unit 30, suspension unit 30 peripheries are then encircled and are established a housing 40 outside, wherein, above-mentioned loudspeaker monomer 20 includes voice coil loudspeaker voice coil 22, sound film 24, interior suspension unit and group of magnets 28, and according to cross section structure schematic diagram shown in Figure 4 as can be known, sound film 24 in the loudspeaker monomer 20 is connected in voice coil loudspeaker voice coil 22, and in general, sound film 24 can be electromagnet, interior suspension unit then comprises the suspention portion 261 and the second interior suspention portion 262 in first, and suspention portion 261 is arranged at an end of sound film 24 in first, 262 other ends that are arranged at sound film 24 of suspention portion in second, and in order to make sound film 24 be able to interact with another permanent magnet and produce the sound, group of magnets 28 be arranged at voice coil loudspeaker voice coil 22 around, therefore can make group of magnets 28 to carry out mutual effect with sound film 24.

When above-mentioned sound film 24 vibrates, the kinetic energy of a part changes into acoustic energy and heat, the energy of a part is absorbed by air damping, all the other most of energy can pass by loudspeaker monomer 20, but because can be by the outer suspension unit 30 that is arranged at loudspeaker monomer 20 peripheries as a spring system that is arranged in the shockproof loud speaker 60, therefore, the probability of utilizing outer suspension unit 30 can make resonance take place reduces, and then makes that the low frequency sound equipment that disappears because of resonance effects is presented.

In order to reduce cost and to simplify complexity on the processing procedure, can utilize identical materials to make 261, the second interior suspention portion 262 and outer suspension unit 30 of suspention portion in first, but, under special product demand, also can utilize different materials to make 261, the second interior suspention portion 262 and outer suspension unit 30 of suspention portion in first.

As for the housing 40 that is arranged at outer suspension unit 30 peripheries, its main function is to make that integral quakeproof loud speaker 60 can be firmly and snugly be assembled on the electronic installation 70, wherein, common electronic installation 70 has TV, notebook computer, mobile phones etc. need be applied to loudspeaker so that the product of sound equipment to be provided, therefore, in order to increase airtight degree, can press from both sides between the face connecing of housing 40 and electronic installation 70 and establish a buffer cell 50, not only can be by providing airtight effect to remedy the problem that connects not driving fit of face between housing 40 and the electronic installation 70, simultaneously, with loudspeaker monomer 20 is benchmark, the sound wave of sound wave before the sound wave direction of transfer that loudspeaker monomer 20 is produced can be divided into loudspeaker monomer 20 generally (C ripple as shown in Figure 4) and two kinds of phase places of loudspeaker monomer 20 back sound waves (D ripple as shown in Figure 4), but, can successfully avoid preceding sound wave and two kinds of different phase places of back sound wave to produce the problem of interference each other by the obstruct of buffer cell 50.Outer suspension unit 30, housing 40 can adopt integrated mode to form the structure that one links to each other with loudspeaker monomer 20.

Comprehensive as can be known above-mentioned, the disclosed shockproof loud speaker utilization ring of the utility model be located at the outer outer suspension unit of loudspeaker monomer and be folded in housing and electronic installation between buffer cell to reach the absorption low frequency energy, the resonance generation probability of loud speaker is reduced significantly, thereby allow the sound equipment of low frequency intactly be presented, simultaneously, also can completely cut off the interference problem between the sound wave of out of phase, in addition, because whole shockproof loud speaker does not have the design of audio amplifier, therefore can reduce cost of manufacture effectively, reduced volume makes shockproof loud speaker more can accord with in the application of the electronic product of microminiaturization now.

The above illustrates characteristics of the present utility model by embodiment, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, and non-limiting claim of the present utility model, do not modify or revise so all other breaks away from the equivalence that spirit that the utility model discloses finishes, must be included in the application's the claim.
