The utility model proposes a kind of projecting apparatus 100, as shown in Figure 1, the ray machine including housing 10 and in housing 10 (not shown) is additionally provided with acoustics unit 30 in housing 10, and acoustics unit 30 is arranged at intervals with ray machine, the lateral wall of acoustics unit 30 Be equipped with damping device between the madial wall of housing 10, damping device is elastic 50, the both ends of elastic 50 respectively with sound equipment The lateral wall of unit 30 is connected with the madial wall of housing 10.

Damping device uses elastic 50, simple in structure, easy to produce, the both ends of elastic 50 directly with acoustics unit 30 Lateral wall and housing 10 madial wall between connect, convenient for the assembling of projecting apparatus 100.Due to setting elastic 50, in sound equipment When unit 30 transfers sound to ray machine, the amplitude that acoustics unit 30 is transferred to ray machine significantly reduces under the action of elastic 50, Reduce the vibration intensity that acoustics unit 30 disturbs the output of ray machine picture.And due to by being transferred to shell after 50 vibration damping of elastic The amplitude of body 10 significantly reduces, and avoids housing 10 and acoustics unit 30 is followed to vibrate, and enables projecting apparatus 100 more smoothly It works under environment.When using projecting apparatus 100, the volume of acoustics unit 30 can be tuned up, can also use has supper bass effect Acoustics unit 30, promoted viewing experience.

Please also refer to Fig. 2, the madial wall of housing 10 is equipped with the first connecting pole 13, and the lateral wall of acoustics unit 30 is equipped with the Two connecting poles 33, the both ends of elastic 50 are connected respectively with the first connecting pole 13 and the second connecting pole 33.First connecting pole is set 13 and second connecting pole 33, increase elastic 50 and housing 10 and the contact area of acoustics unit 30, ensure acoustics unit 30 Bonding strength.First connecting pole 13 and the second connecting pole 33 could be provided as the structure that middle part offers through hole, elastic 50 It fills in respectively in the through hole loaded on the first connecting pole 13 and the second connecting pole 33 at both ends.

Illustratively, the both ends that elastic 50 may be employed are respectively equipped with the first groove for being sheathed on the first connecting pole 13 51 and it is sheathed on the second groove 53 of the second connecting pole 33.And for increasing by 50 and first connecting pole 13 and second of elastic The contact area of connecting pole 33 ensures the reliability of connection.The both ends of first groove 51 and the second groove 53 and elastic 50 lead to Crossing can be by the spreading glue increase bonding strength in gap.

Illustratively, the first connecting pole 13 may be employed to be interference fitted with the first groove 51, the second connecting pole 33 and second The connection mode that groove 53 is interference fitted, since elastic 50 is using elastic material, by the way of interference fit also not Additional auxiliary mounting tool is needed, installation procedure is simple.

Fig. 3 is referred to, the second connecting pole 33 is equipped with the second card slot 331 circumferentially, elastic 50 in the present embodiment The second buckle 531 for being sticked in the second card slot 331 is equipped with close to one end of the second connecting pole 33.In another embodiment, also may be used To be that the first connecting pole 13 is equipped with the first card slot (not shown) circumferentially, elastic 50 is equipped with and is sticked in the first card slot First buckle (not shown).In another embodiment, and can be that the second connecting pole 33 is equipped with the second card slot circumferentially 331, while the first connecting pole 13 is equipped with the first card slot circumferentially, the both ends of elastic 50 are respectively equipped with and the second card slot 331 engage the second buckle 531 and the first buckle are engaged with the first card slot.The above-mentioned structure that is connected together is set, not only facilitates bullet Property 50 and first connecting pole 13 of column and/or two connecting poles 33 connection, also can guarantee its connection reliability.

First groove 51 and the second groove 53 can be the blind hole for being arranged at elastic 50, as shown in Figures 2 and 3；Also may be used To be that the first groove 51 is connected with the second groove 53, as shown in figure 4, the through hole through elastic 50 is formed, to mitigate elastic 50 quality.During the scheme connected using the first groove 51 with the second groove 53, elastic 50 can be spring.

In order to which the position for making acoustics unit 30 consolidates, will lead between the madial wall of the lateral wall of acoustics unit 30 and housing 10 Five elastics 50 are crossed to connect.The arrangement mode of five elastics 50 can be wherein four in the circumferential equal of acoustics unit 30 Cloth, another is located at the center of acoustics unit 30 or five elastics 50 are evenly distributed with along the circumferential direction of acoustics unit 30.

The material of elastic 50 is plastics or rubber, because the elasticity of plastic material or rubber material is all relatively good, and is had Light-weight, easily molded benefit.Elastic 50 is added in projecting apparatus, on the weight of projecting apparatus without too big influence, convenient for projection The carrying of instrument.

Preferably, the material of elastic 50 is thermoplastic polyurethane elastomer rubber, i.e. plastics TPU utilizes thermoplastic poly Urethane elastomer rubber has the characteristics that elasticity is good, physical property is good, various mechanical performances are excellent, makes the effectiveness in vibration suppression of elastic 50 more It is good.

In the application, according to the whole resonant frequency of projecting apparatus 100, the soft or hard value of adjustment 50 material of elastic, to reduce The conduction resonated between 100 internal structure of projecting apparatus.

Elastic 50 can be arranged between 10 upper side wall of housing and the upper side wall of acoustics unit 30, can also be arranged on housing 10 Between 30 downside wall 11 of downside wall 11 and acoustics unit, as shown in Figure 1, in order to make the installation of speaker unit firm, and elastic 50 Good elasticity can be kept, the cloth between 30 downside wall 11 of 10 downside wall 11 of housing and acoustics unit is arranged on using elastic 50 Put mode.

Since acoustics unit 30 is after 50 vibration damping of elastic, the amplitude for being transferred to housing 10 significantly reduces, and by In the reason for the weight of housing 10 itself, the vibration of housing 10 is very small, thus ray machine is fixedly connected on housing 10 can be significantly It eliminates acoustics unit 30 and vibrates caused by ray machine influence, the phenomenon that eliminate float.

Ray machine may be employed buckle-type connection structure and be connected to housing 10, ray machine can also be used to be equipped with screw rod, housing The through hole of screw rod is provided through on 10,10 outside of housing is equipped with the nut for being sheathed on screw rod, ray machine is made to be fixedly connected on housing 10.

Technical solutions of the utility model are set by using between 100 housing 10 of projecting apparatus and the lateral wall of acoustics unit 30 The scheme of elastic 50 is put, influence of the vibration of acoustics unit 30 to housing 10 is reduced, while ray machine is fixedly connected on housing 10, inherently eliminate float.Since housing 10 is influenced smaller be subject to the vibration of acoustics unit 30, connect on the housing 10 The ray machine connect is also smaller by the vibration effect of acoustics unit 30, and projected picture is made not produced with the vibration of acoustics unit 30 Raw jitter phenomenon, makes user while projected picture is watched, can enjoy the high-quality audio that supper bass is brought, and draw Face will not generate jitter phenomenon with the resonance of sound chamber, from the usage experience for utmostly improving user, increase the joy of product Happy property.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, It is every under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes It changes or directly/is used in other related technical areas indirectly and is included in the scope of patent protection of the utility model.
