Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 1, the present invention has the electronic installation of horn mechanism, and its preferred embodiment is a television set, but not as limit, also can be acoustics, or other needs the electronic installation installing loudspeaker.
This electronic installation comprises a casing 1 and and is arranged at horn mechanism 2 in casing 1.
Casing 1 has header board 11, bonnet 12, and one by header board 11 and both bonnets 12 around accommodation space 13, and accommodation space 13 is for holding horn mechanism 2.The medial surface of the contiguous accommodation space 13 of header board 11 is provided with a loudspeaker installation portion 111 installed for horn mechanism 2, and bonnet 12 is provided with the holddown groove 121 at two intervals relative to the one side of header board 11.
Coordinate and consult Fig. 2, in the present embodiment, loudspeaker installation portion 111 has three disjunct guide channels 112,113,114 each other, wherein two guide channel 113,114 fronts elongated and up and down relatively interval arrange, the distance at its interval just can be passed through for horn mechanism 2 closely, another guide channel 112 is in opening towards the U-shaped of aforementioned two guide channels 113,114, and horn mechanism 2 is stretched into can firm being fastened between guide channel 112,113,114 of energy by locating in guide channel 112.In fact apply and be not limited with above-mentioned, the shape of guide channel, configuration, design with corresponding horn shape size.
Consult Fig. 1 again, horn mechanism 2 comprises loudspeaker unit 21, magnet unit 22 and an elastic top arrived piece 23.
The Main Function of loudspeaker unit 21 produces sound for vibrating surrounding air, and loudspeaker unit 21 comprises the vibration cone 212 that a framework 211, is located at framework 211 side, and the resilient snubber 213 that is coated on framework 211 edge, wherein the material of resilient snubber 213 can be soft rubber or sponge.The edge of framework 211 is pushed in guide channel 113,114 by the one end away from guide channel 112 by guide channel 113,114 towards close to guide channel 112 direction together with resilient snubber 213, until a side of framework 211 and resilient snubber 213 is placed in the inside edge of guide channel 112 and is fixed between guide channel 112,113,114, make resilient snubber 213 between framework 211 and guide channel 112,113,114.
The Main Function of magnet unit 22 produces vibration for driving vibration cone 212, and the side of this magnet unit 22 is connected to the opposite side of framework 211 in contrast to vibration cone 212.
Elastic top arrived piece 23 can be that soft rubber or sponge are made, it comprises the bumper post 232 that the two buffering pedestals 231, two being separately fixed at holddown groove 121 are protruded out towards header board 11 direction by buffering pedestal 231 respectively, and one is located at bumper post 232 end and is attached at the cushion pad 233 of magnet unit 22.
Consult Fig. 3, Fig. 4 and Fig. 5, further illustrate horn mechanism 2, in the state of the not coated resilient snubber 213 of loudspeaker unit 21, as can be seen from Fig. 4, the edge of framework 211 is provided with four perforation 214, cushion pad 233 is rounded as shown in Figure 5 and be attached on magnet unit 22, but cushion pad 233 also can be directly arranged on bumper post 232, and need not be attached to magnet unit 22.
Consult Fig. 6 and Fig. 7, the resilient snubber 213 of loudspeaker unit 21 is described.Resilient snubber 213 is edges being coated on framework 211 completely as shown in Figure 7, and resilient snubber 213 is formed with four corresponding projections 215 penetrated in the perforation 214 of framework 211 respectively, is more firmly coated on framework 211 in order to make resilient snubber 213.But in fact if perforation 214 not being set, still resilient snubber 213 can be coated and fixed on framework 211.
Consult Fig. 1 and Fig. 2 again, assembling and the operation situation of the present embodiment horn mechanism 2 are described.First, framework 211 utilizes its edge to insert between two vertical bar shaped guide channels 113,114, and until be resisted against another guide channel 112, make resilient snubber 213 between framework 211 and guide channel 112,113,114, again bonnet 12 is covered towards header board 11 direction, make bumper post 232 be resisted against cushion pad 233, namely complete the installing of horn mechanism 2.When horn mechanism 2 comes into operation, the vibration before and after vibration cone 212 can produce, its vibrational energy can to surrounding transmission; Now by the guide channel 112,113,114 of the present embodiment by loudspeaker unit 21 to be fixed on header board 11 without screw fashion, and the vibration of loudspeaker unit 21 and magnet unit 22 is absorbed by resilient snubber 213 and elastic top arrived piece 23, effectively can reduce loudspeaker unit 21 and magnet unit 22 vibrational energy is passed to casing 1, produce unnecessary noise to reduce casing 1 because of resonance.
It should be noted that, during enforcement, also can extend guide channel 113,114 to be connected to form with guide channel 112 is respectively a guide channel, and framework 211 is all placed in this guide channel together with resilient snubber 213.Or the guide channel of other form also can be implemented, as long as this framework 211 can be fixed on header board 11, be not limited with above-described embodiment.
In sum, design by guide channel of the present invention, and the resilient snubber 213 being coated on framework 211 edge and the elastic top arrived piece 23 be resisted against between magnet unit 22 and bonnet 12, except loudspeaker unit 21 being fixed on header board 11 without screw fashion, effectively can also reduce casing 1 to produce with horn mechanism 2 and resonate, so really object of the present invention can be reached.
