Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Embodiment 1:
Shown in Fig. 1-4, the disclosed a kind of loudspeaker acoustic enclosure of present embodiment mainly comprises: casing (not drawing among the figure) and the loud speaker that is arranged on box house.This loud speaker mainly comprises phase inverting box, vibrating diaphragm 101, driver 102 (being commonly called as driving head).
The casing that wherein falls is made up of stuffing box 104 and phase-reversing tube 103 (claiming conduit again), one end of phase-reversing tube 103 is with the air communication in the case, the other end leads to outside the case by the paraphase mouth on the tank wall of described stuffing box 104, when the vibrating diaphragm 101 of loud speaker moves, directly external on the one hand radiative acoustic wave, the air in compression again (or expansion) case on the other hand.Control gas in the case is ejected from the paraphase mouth, like this, the paraphase mouth has just become to instigate air " second vibrating diaphragm 101 ", if design ingeniously, phase-reversing tube 103-box system can just make sound wave paraphase 180 degree (therefore phase inverting box gains the name) of vibrating diaphragm 101 backward radiation, the sound wave that radiate from opening part is just with the sound wave homophase of vibrating diaphragm 101 the place ahead radiation like this, and the radiation of homophase makes acoustic energy obtain stack, so strengthen and extended audio amplifier LF-response generally.Phase inverting box and the airtight backward radiation energy that utilizes vibrating diaphragm 101, thereby efficient is than higher.
Driver 102 is contained on the basin frame of described stuffing box 104, and bonding with vibrating diaphragm 101; Vibrating diaphragm 101 sealings cover the opening part of stuffing box 104, and vibrating diaphragm 101 is provided with two mesopores, fix being fixed with a driver 102 respectively on two mesopores.
Therefore, use the present embodiment technical scheme, because the loud speaker of present embodiment adopts the phase inverting box design, can effectively avoid acoustic short circuit.By phase-reversing tube 103, can from phase-reversing tube 103, pour out some to the low frequency energy of loud speaker back side radiation and come, simultaneously with the low frequency energy phase superposition of surface radiation before the loud speaker.Produce better low-frequency effect, thereby can obtain the effect of preferable audio amplifier, so the loudspeaker acoustic enclosure of present embodiment is with respect to acoustic short circuit phenomenon loudspeaker monomer takes place in the prior art easily, adopt the favourable raising acoustical quality of this loudspeaker acoustic enclosure, help adopting less size to obtain the audio of higher-wattage and quality.
In addition, in the present embodiment, establish in order to make the loudspeaker acoustic enclosure main body of present embodiment more be applicable in the electrical equipment, can so that the length of phase inverting box greater than the width and the thickness of described phase inverting box, thereby make that its loud speaker width is narrower, thickness is longer than book, length, make it bear power and can reach 5-7W.Big with respect to the bore by the increasing loud speaker in the prior art, as to thicken thickness loudspeaker acoustic enclosure, the loud speaker impression in the present embodiment is applicable to the overall dimension and the thickness requirement of Related products such as TV more, helps the thinning design of these electrical equipment.
For further on the basis of improving loud speaker audio power and audio, help its star thinning design, in this enforcement, can select the driver 102 of double-tone circle driver 102 for use as present embodiment.Such as designing requirement is that loudspeaker impedance is 8 Ω, and the connection of voice coil line adopts series connection and mode in parallel to satisfy client's impedance requirements, and parallel connection is 16 Ω+16 Ω, and the voice coil line footpath is thinner, and it is relatively also little to bear power. series connection is 4 Ω+4 Ω.The voice coil line footpath is thicker, and it is relatively large to bear power.In the present embodiment, consider that this product power requirement is big, the preferred mode that adopts series connection.
In the present embodiment, this loudspeaker acoustic enclosure is preferred but be not limited to adopt dual drive 102 designs, loads onto the distance of 102. two drivers 102 of two drivers and will determine according to the length of vibrating diaphragm 101 on the basin frame.After the centre-to-centre spacing of driver 102 is determined, reenact out the centre-to-centre spacing of 101 two mesopores of vibrating diaphragm, these two sizes are essential accurate and consistent.Adopt this embodiment can be so that the power averaging of two drivers 102 distributes. be the design of single driver 102 and single-tone circle in the past, all power need undertake the whole thing. and when former dimensions when loudspeaker acoustic enclosure was identical, the loud speaker of two driving magnetic circuits bore more powerful than single loud speaker that drives magnetic circuit in the prior art.
At present embodiment, can but be not limited to by the bonding driver 102 of liquid glue layer, concrete operations are that the basin frame of packing into uses liquid glue (biliquid glue) fixing bonding then after driving head is combined into magnetic circuit and smears through magnetizing.
Can also be disjunctor with basin frame and cabinet design in the present embodiment, utilize box sizes, vibrating diaphragm 101 is carried out maximized design, help improving the sensitivity of loud speaker.
In the time of in above-mentioned loudspeaker acoustic enclosure being built in TV or other display electrical equipment, can between the casing of the housing (specifically being erection column) of electrical equipment main body and loudspeaker acoustic enclosure, establish rubber cushion by separation pad, such as silicagel pad or the like, this separation pad is established rubber cushion and is provided with and is beneficial to the raising shockproof effect.The material of quakeproof rubber pad is a silica gel, and hardness can be adjusted according to the demand of reality, is generally about 30 degree, thereby effectively prevents the machine shake, helps improving audio.
Concrete, a kind of electrical equipment with loudspeaker acoustic enclosure that present embodiment provides mainly comprises electrical equipment main body and the loudspeaker acoustic enclosure that is built in described electrical equipment body interior.Wherein the design of loudspeaker acoustic enclosure is as described above.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
