Abstract
The utility model discloses a sound system for a virtual surround flat-panel television set and solves the problems in the prior art that the wiring is complex, the television set is unmatched with home furnishing, sound positioning is inaccurate and the restoration force is poor. The sound system is characterized in that a host of the sound system is of a long strip structure; the host is divided into a left cavity and a right cavity which are independent as well as two channel power amplifier modules in the middle of the host; and the left cavity and the right cavity can be used for respectively accommodating one, two or more loudspeakers. A wireless bass signal transmitting module matched with a wireless active subwoofer is arranged in the middle of the host. The sound system disclosed by the utility model has the benefits that the wiring is simple; the cost is reduced; and virtual and vivid surround is obtained.
Description
Technical field
The utility model relates to a kind of virtual surround sound panel TV set sound system.
Background technology
Present panel TV is constantly pursued the improvement of ultra-thin and image quality; Can under ultra-thin structural limitations, cause the design requirement that can't satisfy high-quality acoustic construction; Especially cause the shake of television set machine easily at low frequency and high frequency, so high frequency and low-frequency range to television set that present television manufacturer can be had a mind to decay; Be exactly the restriction of superthin structure in addition; Cause a lot of television factories not only to accomplish the loud speaker bore of television set to minimize, also install loud speaker downwards or backward simultaneously, cause the loudspeaker sound transmission characteristic to be badly damaged like this; So cause the common hard defective that exists of present panel TV; TV is thin more, and image quality is become better and better, can be exactly sound worse and worse.Because the lower tone of panel TV; So much human can be remembered home theater; The complete surround sound family of one cover is minimum to comprise that six audio amplifiers (of two of front tank, two in rearmounted case, mid-, bass box) add one in power amplifier main frame (being integrated in the audio amplifier of having can not add) again; With so many audio amplifiers not only occupation of land side that links together; Also wiring complicated, cost an arm and a leg, also can break the Total tune property of household decoration sometimes, can't satisfy the modern life of the succinct fashion that present people pursues.
Also having a kind of panel TV set audio amplifier, is exactly simply will its structure outward appearance can be arranged in pairs or groups with television set around simple integrated being distributed in the bar shaped audio amplifier of six sound channels of home theater; Though it is numerous and diverse that this type audio amplifier has reduced wiring, do not take up space, can owing to it is that six audio amplifiers are integrated on one; Each audio amplifier is sounding separately all; When they at the same time during sounding because the acoustic transmission characteristic causes their can phase inter-modulation, sound localization is inaccurate, the reducing power extreme difference; Its structure needs independently power amplification circuit of six loudspeaker units and six tunnel at least simultaneously, also causes its cost of manufacture expensive partially.
Summary of the invention
The purpose of the utility model is: a kind of surround sound panel TV set sound system is provided, exists and solve that wiring is numerous and diverse, television set is not arranged in pairs or groups with the household decoration and the inaccurate problem that reaches the reducing power difference of sound localization to solve prior art.
Reaching the technical scheme that the purpose of the utility model takes is: a kind of virtual surround sound panel TV set sound system; It is characterized in that: its main frame is rectangular strip structure; Main frame is divided into the two sound channel power amplifier modules at independent left and right left side cavity and right cavity and middle part, and left cavity and right cavity can be put one, or two or more loud speakers respectively.
The main frame middle part also can comprise the wireless bass signal emission module with wireless active subwoofer coupling.
The utility model two sound channel power amplifier modules also comprise circuit such as audio frequency input, digital audio and video signals reception, digital audio and video signals decoding, digital audio processing and two channel audio power amplifications.The input interface aspect comprises power input interface, optical fiber, the input of coaxial, HDMI digital signal and simulation stereo input of RCA or 3.5 stereo input interfaces.
The beneficial effect that the utility model reaches is: the advantage that adopts the utility model to reach is:
The utility model taken into full account modern tame reload request and with the collocation of television set, go so be easy to incorporate in the house ornamentation environment.
2 the utility model adopt a strip global design, built-in power amplifier, complete machine have only power supply wiring and with the signal connecting line of audio frequency apparatus, so wiring is simple.
3. the power amplifier module has comprised circuit such as digital audio and video signals reception, digital audio and video signals decoding, digital audio processing; Make this sound equipment because built-in digital received and decoding circuit; So can directly receive, decode from the digital audio and video signals of audio & video equipment; Effective like this D/A switch and the transmission distortion of avoiding the audio signal transmission process meets modern high definition audio transmission requirement.Connect more succinctly as long as single line just can solve than analog signal simultaneously; The embedded digital audio frequency processing circuit utilizes now well-known audio to handle the ripe surround sound process software algorithm of company, can go out surrounding sound effect true to nature through preposition simple two channel loudspeaker system virtualizations.
4. because this speaker system has only rectangular two sound channels designs (or adding a wireless active subwoofer), so cost has very big cost advantage than traditional-family's cinema system.
Description of drawings
Fig. 1: be the structural representation of the utility model.
Fig. 2: the structural representation that wireless bass signal transmitter module is arranged for the utility model.
Embodiment
The architectural feature of the utility model more at large is described below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2; A kind of virtual surround sound panel TV set sound system; Its main frame is rectangular strip structure; Main frame is divided into the two sound channel power amplifier modules 3 at independent left and right left side cavity 1 and right cavity 2 and middle part, and left cavity 1 can be put one or two or more loud speaker 4 respectively with right cavity 2.Two sound channel power amplifier modules also comprise circuit such as audio frequency input, digital audio and video signals reception, digital audio and video signals decoding, digital audio processing and two channel audio power amplifications.The main frame middle part also can comprise the wireless bass signal emission module 5 with wireless active subwoofer 6 couplings.The input interface aspect comprises power input interface, optical fiber, the input of coaxial, HDMI digital signal and simulation stereo input of RCA or 3.5 stereo input interfaces.
