The present invention proposes a kind of television set.
Referring especially to Fig. 1 and Fig. 2, in an embodiment of the present invention, this television set includes TV body 10,
TV body 10 can be tabular, it is also possible to be curved, described TV body 10 is provided with to
A few speaker system 20, wherein, can arrange speaker system 20 in any position of TV body 10,
When TV body 10 is in flat board or during curved, can be respectively provided with in the horizontal both sides of TV body 10
Speaker system described in one, or be respectively provided with described in one in the both sides of the vertical direction of TV body 10 and raise one's voice
Device system；It is of course also possible to side is separately provided wherein, the most do not limit.
In the present embodiment, for improving the voice output effect of television set, above-mentioned speaker system 20 includes many
Individual vertically or horizontal direction linearly array arrange loudspeaker 30.The most vertically arrange
Speaker system 20 be preferably provided at the both sides of horizontal direction of TV body 10, set in the horizontal direction
The speaker system 20 put is preferably provided at the both sides of the vertical direction of TV body 10.
It should be appreciated that this speaker system 20 be one group by arrangement be approximated to straight line, be spaced closely together,
The radiating element of multiple loudspeakers 30 composition that amplitude is identical, phase place is identical, this loudspeaker 30 can be cone
Shape loudspeaker 30 or panel speaker 30, naturally it is also possible to for the loudspeaker 30 of other shapes, herein
Do not limit.Due to speaker system 20 multiple loudspeakers 30 vertically or horizontal direction linear array
Arrange so that the voice signal of each loudspeaker 30 output is narrow beam in the directive property of main shaft vertical plane,
Energy supposition can radiate at a distance, thus provides the directive property of the best vertical coverage rate, TV
Machine just can obtain good sound effect when playing sound.
Further, television set is typically in indoor use, and acoustic surrounding is because ground and ceiling are easily formed instead
Penetrate sound, when reflected sound is added on direct sound wave, cause equal very big in the interval of the frequency of occurrences on signal spectrum
Value and minimum, present comb filtering phenomenon, be referred to as " pectination distortion, " its disturbing effect to music
Bigger.And the speaker system 20 of linear array can reduce the projectional angle of vertical plane, therefore can reduce
The impact of comb-filter effect, and reduce indoor effective reverberation, thus improve the sound effect of television set
Really.
Furthermore, it is necessary to explanation, the speaker system 20 that linear array is arranged, its radiation is divided near field
And far field.Near field can approximate regards line source radiation cylindrical wave as, listens to effect preferably, far-field approximation point sound
Source radiation spherical wave, listens to effect poor.Because the frequency of speaker system 20 is at more than 10kHz (hertz)
It is approximate spherical wave radiation, it is impossible to meet cylindrical wave requirement, so the target upper limit frequency of speaker system 20
Rate f preferably 10kHz does critical, is certainly not limited to 10KHZ.If the linear battle array of speaker system 20
Row height h is 0.5m (rice).Utilize near field and far field boundary distances formula d=1.5fh2(formula 1), it is known that, d
=3.75 meters, then the boundary distances near field and far field is 3.75 meters, meets the use requirement of general home environment.
Therefore, for general home environment, the speaker system 20 using linear array height to be 0.5m can be mended
Repay defect too much because of the sound pressure level decay with distance increasing at a distance, make room sound field tend to uniform.Permissible
Being understood by, the speaker system 20 of different array heights has different boundary distances, accordingly, permissible
Near field according to television set specific use environment and the boundary distances in far field, the corresponding array of design is high in turn
The speaker system 20 of degree, listens to demand to meet.
In the present embodiment, line array loudspeaker system 20 is to be formed by 30 casees right angle settings of multiple loudspeakers,
Due to reasons such as loudspeaker 30 box plate thickness, between neighbouring two-loudspeaker 30, there is spacing,
Such as the D in Fig. 2, cause adjacent two sound source to produce interference and cause the discontinuous of line source, therefore in reality
In the application of border, two the described loudspeakers 30 as far as possible keeping neighbouring are close to arrange, but the most do not limit
Fixed, can also be at regular intervals in other embodiments, need to ensure, maximum space or
Sound source wavelength X is have to be lower than away from D.It should be noted that when space D is less than or equal to λ, wave surface
It is smooth；When space D is more than or equal to λ, wave surface starts the bending that rises and falls；And when space D about etc.
When 2 λ, wave surface is pectinate line.Therefore, this wavelength X is speaker system 20 actual operating frequency
The upper limit, and the vertical range between this upper limiting frequency with adjacent two-loudspeaker 30 is inversely proportional to, i.e.
Wherein, fhFor the upper limiting frequency of speaker system 20, c is the velocity of sound, generally 344m/s.Wherein, lower limit
Frequency depends on the total height of speaker system 20.
If speaker system 20 uses the circular loudspeakers 30 of 16 1 inch to form, general family to be met
Use requirement, then it is required that the linear array height h of speaker system 20 that is combined into of 16 loudspeakers 30
For 0.5m (rice), design pitch D is i.e. wanted to substantially meet h/16=0.03125m=31.25mm (millimeter).
If upper limiting frequency f of speaker system 20h≈ 5kHz, then D ≈ 0.032mm, it is clear that do not reach design
Requirement；If upper limiting frequency fhFor 20kHz, then D=17.2mm, it is clear that also do not reach design requirement；False
If upper limiting frequency fhFor 10kHz, then D=34.4mm, compare with the value of target distance D relatively near, meet
Design requirement, as shown in Figures 3 and 4, second complementary wave occurs in far field, and on listening to, impact is little.
In the present embodiment, TV line array loudspeaker system 20 vertical plane radiation to be controlled angle, make to listen
The ear of person, in radiation scope, can improve at least through following two mode.
First method is to change the radiated time of every loudspeaker 30 in line array loudspeaker system 20, logical

The driving means (not shown) of sound device 30, described driving means electrically connects with described controller；Described
Controller for controlling the radiated time of the plurality of loudspeaker 30 by described driving means correspondence.Wherein,
Controller exports the sequential driving signal to each loudspeaker 30 by controlling driving means, to realize control
The radiated time of every loudspeaker 30.
Preferably, described controller controls described driving means according to default time interval output driving letter
Number, depend on to direction, bottom by top according to described default time interval controlling the plurality of loudspeaker 30
Secondary sounding or control the plurality of loudspeaker 30 according to described default time interval by bottom to top side
To sounding successively.The mode of the preferred embodiment is from the beginning of the loudspeaker 30 of top or bottom, passes through
Progressively postpone the voice output time of back speakers 30, make system directive property deflect.Such as, interval 0.3
Deflectable 10 degree of ms, 0.9ms then deflects 30 degree.This time difference from system top down increasing or decreasing,
Then yawing moment is on the upper side or on the lower side.
Second method is the flexibility changing speaker system 20, the differently curved journey of speaker system 20
Degree is equivalent to postpone between loudspeaker 30 casing different time, also corresponds to offset different angles.
