Abstract
The utility model relates to planar loudspeaker boxes, which comprises the frame of the loudspeaker box, a vibrating acoustical generator, a driver mounted on the vibrating acoustical generator, and a rear end plate; a frequency demultiplier and a high pitch loudspeaker are also equipped inside of the planar loudspeaker box. The vibrating acoustical generator is connected with the frame of the loudspeaker box to form one via the elastic edge of rubber; the driver is sheathed on the rear end plate and equipped with heat radiating fins, and the rear end plate is evenly equipped with sound-absorbing columns. The vibrating acoustical generator is made into a planar structure by using a KT plat plate, and the rear end plate is equipped with gas vents. The utility model has the advantages of full melody, sufficient bass vibration, excellent sound quality, simple structure, etc.
Description
Affiliated technical field
The utility model relates to a kind of plat sound box that can carry out electric energy and sound conversion.
Background technology
At present, multiple plat sound box is arranged on the market, but these flat boards not because structure unreasonable, be exactly that the device installed because of inside is incomplete, and cause the tonequality audio poor, do not accepted by market.A kind of plat sound box as Chinese patent CN2425468Y bulletin, it comprises chatter device, driver and the phase adjusted case of slab construction, framework directly is connected with the vibration sounding device, the vibration sounding device is the two surface texture flat boards of strap clamp sandwich layer, this flat board is single wave laminboard layer cardboard or double wave wave laminboard layer cardboard, and driver is fixed on the framework by support arm; The plat sound box of this structure because of there not being the cooperation of high pitch loudspeaker, causes tone single; The vibration sounding device is directly to be connected with framework, makes that the vibration of vibration sounding device is insufficient, sensitivity descends, and also influences the effect of bass.
Summary of the invention
The purpose of this utility model provides a kind of box audio amplifier acoustic advantage that has, plat sound box simple in structure, that the tonequality audio is good.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of plat sound box, comprise the audio amplifier frame, the vibration sounding device, be installed in driver and back shroud on the vibration sounding device, frequency divider and high pitch loudspeaker also are installed in the plat sound box, and the vibration sounding device links into an integrated entity by rubber bullet limit and audio amplifier frame.
Driver sleeve is contained on the back shroud and fin is installed on it, evenly is provided with sound absorbing post on the back shroud.
Above-mentioned vibration sounding device is to make a kind of slab construction with the KT flat board, offers gas port on the back shroud.
The beneficial effects of the utility model are that because frequency divider and high pitch loudspeaker have been installed, the treble of music just can well send, and makes that happy accent is full; Connect vibration sounding device and audio amplifier frame with the rubber shell fragment, can make the bass vibration fully, audio improves; Driver sleeve is contained on the back shroud and sound absorbing post is set on back shroud and offers gas port, has not only improved tonequality but also simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is a rearview of the present utility model.
Among the figure 1, the audio amplifier frame, 2, the rubber shell fragment, 3, high pitch loudspeaker, 4, the vibration sounding device, 5, driver, 6, frequency divider, 7, back shroud, 8, sound absorbing post, 9, fin, 10, gas port.
Embodiment
In Fig. 1 and 3, the understanding that can be perfectly clear audio amplifier frame 1 of the present utility model is connected and the position distribution of high pitch loudspeaker 3 by rubber shell fragment 2 and the vibration sounding device made from the KT plate 4, and the driver 5 of suit is positioned at the center and offers gas port not of uniform size 10 on the back shroud 7; Driver 5 can be one or more, serves as the fixed point balanced distribution but need the center with vibration sounding device 4.
By structure shown in Figure 2, can realize the utility model easily, this plat sound box comprises audio amplifier frame 1, and the vibration sounding device 4 of slab construction is installed in the driver 5 on the vibration sounding device 4, and vibration sounding device 4 is connected with the audio amplifier frame by rubber shell fragment 2; Frequency divider 6 is installed on the back shroud 7, the sound absorbing post 8 of many one-tenth spot distribution is set at the medial surface of back shroud 7.
For improving radiating effect, fin 9 is installed on the driver 5; For obtaining the good sound quality effect, the foamed plastic KT plate that vibration sounding device 4 adopts lightweight easily to vibrate is made.
Cavity is offered at the position of the vibration sounding device 4 corresponding high pitch loudspeakers 3 of slab construction, so that the spreading out of of sound; Outer terminal is installed on the frequency divider 6 and is connected with high pitch loudspeaker 3 with driver 5 respectively by lead.
