本发明涉及电视机技术领域，尤其涉及一种电视机。The invention relates to the technical field of televisions, in particular to a television.
背景技术Background technique
近年来OLED(Organic Electroluminescence Display，有机电激光显示)开始流行市场，其超薄的厚度和弯曲的机身给用户带来了不一样的用户体验。In recent years, OLED (Organic Electroluminescence Display, organic electroluminescence display) has become popular in the market, and its ultra-thin thickness and curved body have brought different user experience to users.
但是，正是由于超薄的厚度和弯曲的机身给电视伴音带来了难题。因为音质较好的扬声器其本身的厚度和音箱体积较大，所以，在满足电视机超薄的同时，难以满足电视伴音的需求。However, it is precisely because of the ultra-thin thickness and curved body that it poses a problem for TV sound. Because the thickness of the speakers with better sound quality and the volume of the speakers are relatively large, it is difficult to meet the needs of TV sound accompaniment while satisfying the ultra-thin TV sets.
目前，市面上的大部分电视机基本采用独立的音箱与电视搭配，或独立的音箱底座来支撑声音的重放，结果是电视机本机超薄，音箱却很大，整体造型不强；也有部分电视机采用较薄的喇叭和较小的箱体，造型要求满足了，但小喇叭和小空间使得声音质量较差。At present, most TVs on the market basically use independent speakers to match the TV, or independent speaker bases to support sound playback. The result is that the TV is ultra-thin, but the speakers are large and the overall shape is not strong; Some TVs use thinner speakers and smaller cabinets, which meet the styling requirements, but the small speakers and small space make the sound quality poor.

本发明提出一种电视机。The invention proposes a television.
主要参照图1及图2，在本发明一实施例中，该电视机包括电视主体10，电视主体10可以是平板状，也可以是曲面状，所述电视主体10上设置有至少一扬声器系统20，其中，可在电视主体10的任何位置设置扬声器系统20，当电视主体10呈平板或者曲面状时，可以在电视主体10的水平两侧各设有一所述扬声器系统，或者在电视主体10的竖直方向的两侧各设有一所述扬声器系统；当然，也可以在其中一侧单独设置，此处并不限定。Mainly referring to Fig. 1 and Fig. 2, in one embodiment of the present invention, the TV set includes a TV main body 10, the TV main body 10 can be flat or curved, and the TV main body 10 is provided with at least one speaker system 20, where the speaker system 20 can be installed at any position of the TV body 10, when the TV body 10 is flat or curved, a speaker system can be provided on each horizontal side of the TV body 10, or on the TV body 10 A speaker system is provided on both sides of the vertical direction; of course, it can also be provided separately on one side, which is not limited here.
本实施例中，为提高电视机的声音输出效果，上述扬声器系统20包括多个沿竖直方向或水平方向呈线性阵列设置的扬声器30。其中沿竖直方向设置的扬声器系统20优选设置在电视主体10的水平方向的两侧，沿水平方向设置的扬声器系统20优选设置在电视主体10的竖直方向的两侧。In this embodiment, in order to improve the sound output effect of the TV, the speaker system 20 includes a plurality of speakers 30 arranged in a linear array along the vertical or horizontal direction. The speaker system 20 arranged in the vertical direction is preferably arranged on both sides of the TV main body 10 in the horizontal direction, and the speaker system 20 arranged in the horizontal direction is preferably arranged on both sides of the TV main body 10 in the vertical direction.
应当理解的是，该扬声器系统20是一组由排列近似成直线、间隔紧密、振幅相同、相位相同的多个扬声器30组成的辐射单元，该扬声器30可为锥形扬声器30或者平板扬声器30，当然也可以为其他形状的扬声器30，此处不限。由于扬声器系统20的多个扬声器30沿竖直方向或水平方向线性阵列设置，使得各扬声器30输出的声音信号在主轴垂直平面的指向性呈窄波束，能量叠加可以远距离辐射，从而提供非常良好的垂直覆盖面的指向性，电视机在播放声音时就能够取得良好的声音效果。It should be understood that the loudspeaker system 20 is a group of radiating units composed of a plurality of loudspeakers 30 arranged approximately in a straight line, closely spaced, with the same amplitude and the same phase. The loudspeakers 30 may be cone loudspeakers 30 or flat loudspeakers 30, Of course, other shapes of the speaker 30 may also be used, which is not limited here. Since a plurality of loudspeakers 30 of the loudspeaker system 20 are arranged in a vertical or horizontal linear array, the directivity of the sound signals output by each loudspeaker 30 in the vertical plane of the main axis is a narrow beam, and energy superposition can be radiated from a long distance, thereby providing a very good With the directivity of the vertical coverage, the TV can achieve good sound effects when playing sound.
并且，电视机一般在室内使用，听音环境因为地面和天花板容易形成反射声，当反射声叠加到直达声上，导致信号频谱上出现频率间隔相等的极大值和极小值，呈现出梳状滤波现象，被称为“梳状失真，”它对音乐的干扰效应比较大。而线性阵列的扬声器系统20能够减小垂直面的投射角，因此可减少梳状滤波效应的影响，并降低室内有效混响时间，从而提高电视机的声音效果。In addition, TVs are generally used indoors, and the listening environment is prone to reflected sound due to the ground and ceiling. When the reflected sound is superimposed on the direct sound, the maximum and minimum values with equal frequency intervals appear on the signal spectrum, showing a comb. The filtering phenomenon, known as "comb distortion," has a relatively large disturbing effect on music. The linear array speaker system 20 can reduce the projection angle of the vertical plane, thus reducing the influence of the comb filter effect and reducing the effective reverberation time in the room, thereby improving the sound effect of the TV set.
此外，需要说明的是，线性阵列设置的扬声器系统20，其辐射分为近场和远场。近场可近似看成线声源辐射柱面波，聆听效果较好，远场近似点声源辐射球面波，聆听效果较差。因为扬声器系统20的频率在10kHz(赫兹)以上是近似球面波辐射，不能满足柱面波要求，所以扬声器系统20的目标上限频率f优选为10kHz做临界，当然并不限定为10KHZ。若扬声器系统20的线性阵列高度h为0.5m(米)。利用近场和远场分界距离公式d＝1.5fh2(式1)，可知，d＝3.75米，则近场和远场的分界距离为3.75米，满足一般家庭环境的使用要求。因此，对于一般家庭环境，采用线性阵列高度为0.5m的扬声器系统20可以补偿远处因随距离加大而声压级衰减过多的缺陷，使室内声场趋于均匀。可以理解的是，不同阵列高度的扬声器系统20具有不同的分界距离，据此，可以根据电视机特定使用环境的近场和远场的分界距离，反过来设计对应阵列高度的扬声器系统20，以满足聆听需求。In addition, it should be noted that the radiation of the speaker system 20 arranged in a linear array is divided into near field and far field. The near field can be approximated as a line sound source radiating cylindrical waves, and the listening effect is better, while the far field is approximated as a point sound source radiating spherical waves, and the listening effect is poor. Because the frequency of the speaker system 20 above 10kHz (Hertz) is approximately spherical wave radiation, which cannot meet the requirements of cylindrical waves, the target upper frequency f of the speaker system 20 is preferably 10kHz as the critical limit, and certainly not limited to 10KHZ. If the linear array height h of the loudspeaker system 20 is 0.5 m (meter). Using the formula d=1.5fh2 (Equation 1) for the boundary distance between the near field and the far field, it can be seen that if d=3.75 meters, the boundary distance between the near field and the far field is 3.75 meters, which meets the requirements for use in general home environments. Therefore, for a general home environment, using the speaker system 20 with a linear array height of 0.5m can compensate for the defect that the sound pressure level attenuates too much in the distance as the distance increases, so that the indoor sound field tends to be uniform. It can be understood that speaker systems 20 with different array heights have different boundary distances. Accordingly, speaker systems 20 corresponding to array heights can be conversely designed according to the boundary distances of near-field and far-field in the specific use environment of the TV set, so as to Meet listening needs.
本实施例中，线阵列扬声器系统20是由多个扬声器30箱垂直安装而成，由于扬声器30箱体板厚度等原因，上下相邻的两扬声器30之间是有间距的，如图2中的D，导致相邻的两个声源产生干涉引起线声源的不连续，因此在实际应用中，尽量保持上下相邻的两个所述扬声器30紧贴设置，但此处并不限定，在其他实施例中也可以是有一定间距，需要保证的是，最大的空隙或间距D必须低于声源波长λ。需要说明的是，当间距D小于等于λ时，波阵面是平滑的；当间距D大于等于λ时，波阵面开始起伏弯曲；而当间距D约等于2λ时，波阵面呈梳状线。因此，这个波长λ是扬声器系统20实际工作频率的上限，且该上限频率与相邻两扬声器30之间的垂直距离成反比，即其中，fh为扬声器系统20的上限频率，c为声速，一般为344m/s。其中，下限频率取决于扬声器系统20的总高度。In the present embodiment, the line array loudspeaker system 20 is formed by vertically installing a plurality of loudspeaker 30 boxes. Due to reasons such as the thickness of the loudspeaker 30 box body boards, there is a distance between the upper and lower adjacent two loudspeakers 30, as shown in FIG. 2 D, resulting in the interference of two adjacent sound sources causing the discontinuity of the line sound source, so in practical applications, try to keep the two adjacent speakers 30 close to each other, but it is not limited here. In other embodiments, there may also be a certain distance, and what needs to be ensured is that the largest gap or distance D must be lower than the wavelength λ of the sound source. It should be noted that when the distance D is less than or equal to λ, the wave front is smooth; when the distance D is greater than or equal to λ, the wave front begins to undulate and bend; and when the distance D is approximately equal to 2λ, the wave front is comb-like Wire. Therefore, this wavelength λ is the upper limit of the actual operating frequency of the speaker system 20, and the upper limit frequency is inversely proportional to the vertical distance between two adjacent speakers 30, namely Wherein, fh is the upper limit frequency of the speaker system 20, and c is the speed of sound, which is generally 344m/s. Wherein, the lower limit frequency depends on the overall height of the speaker system 20 .
假若扬声器系统20采用16个1英寸的圆形扬声器30组成，要满足一般家庭使用要求，则需要使得16个扬声器30组合成的扬声器系统20的线性阵列高度h为0.5m(米)，即要设计间距D基本满足h/16＝0.03125m＝31.25mm(毫米)。If the loudspeaker system 20 is composed of 16 1-inch circular loudspeakers 30, to meet the requirements of general household use, it is necessary to make the linear array height h of the loudspeaker system 20 composed of 16 loudspeakers 30 be 0.5m (meter), that is, The design distance D basically satisfies h/16=0.03125m=31.25mm (mm).
假若扬声器系统20的上限频率fh≈5kHz，则D≈0.032mm，显然达不到设计要求；假若上限频率fh为20kHz，则D＝17.2mm，显然也达不到设计要求；假若上限频率fh为10kHz，则D＝34.4mm，与目标间距D的值比较较近，满足了设计需求，如图3及图4所示，第二个副波出现在远场，对聆听影响小。If the upper limit frequency fh of the loudspeaker system 20 is ≈5kHz, then D≈0.032mm, which obviously does not meet the design requirements; if the upper limit frequency fh is 20kHz, then D=17.2mm, which obviously does not meet the design requirements; if the upper limit frequency fh is 10kHz, then D=34.4mm, which is relatively close to the value of the target distance D, which meets the design requirements. As shown in Figure 3 and Figure 4, the second secondary wave appears in the far field and has little impact on listening.
本实施例中，电视用线阵列扬声器系统20要控制垂直面辐射角度，使听者的耳朵在辐射范围内，可至少通过以下两种方式来改善。In this embodiment, the line array speaker system 20 for television needs to control the radiation angle of the vertical plane so that the listener's ears are within the radiation range, which can be improved in at least the following two ways.
第一种方法是改变线阵列扬声器系统20中每只扬声器30的辐射时间，通过合理的控制每只扬声器30的辐射时间，使系统指向性偏转。The first method is to change the radiation time of each speaker 30 in the line array speaker system 20, and deflect the directivity of the system by controlling the radiation time of each speaker 30 reasonably.
具体地，上述电视机还包括控制器(图未示出)及用于驱动所述多个扬声器30的驱动装置(图未示出)，所述驱动装置与所述控制器电连接；所述控制器用于通过所述驱动装置对应控制所述多个扬声器30的辐射时间。其中，控制器通过控制驱动装置输出至各扬声器30的驱动信号的时序，以实现控制每只扬声器30的辐射时间。Specifically, the above TV set also includes a controller (not shown) and a driving device (not shown) for driving the plurality of speakers 30, the driving device is electrically connected to the controller; The controller is used for correspondingly controlling the radiation time of the plurality of speakers 30 through the driving device. Wherein, the controller realizes controlling the radiation time of each loudspeaker 30 by controlling the timing of the driving signal outputted by the driving device to each loudspeaker 30 .
优选地，所述控制器控制所述驱动装置按照预设的时间间隔输出驱动信号，以控制所述多个扬声器30按照所述预设的时间间隔由顶端至底端方向依次发声或者控制所述多个扬声器30按照所述预设的时间间隔由底端至顶端方向依次发声。该优选实施例的方式是从顶端或者底端的扬声器30开始，通过逐步延迟后面扬声器30的声音输出时间，使系统指向性偏转。例如，间隔0.3ms可偏转10度，0.9ms则偏转30度。这个时间差从系统上部往下递增或递减，则偏转方向为偏上或偏下。Preferably, the controller controls the driving device to output a driving signal according to a preset time interval, so as to control the plurality of speakers 30 to make sound sequentially from the top to the bottom according to the preset time interval or to control the The multiple speakers 30 emit sound sequentially from the bottom to the top according to the preset time interval. The method of this preferred embodiment is to deflect the directivity of the system by gradually delaying the sound output time of the rear speaker 30 starting from the top or bottom speaker 30 . For example, it can be deflected by 10 degrees at an interval of 0.3ms, and it can be deflected by 30 degrees at an interval of 0.9ms. This time difference increases or decreases from the top of the system downwards, and the deflection direction is upward or downward.
第二种方法是改变扬声器系统20的弯曲度，扬声器系统20的不同弯曲程度相当于扬声器30箱体间延迟不同时间，也相当于偏移不同角度。The second method is to change the degree of curvature of the speaker system 20 . Different degrees of curvature of the speaker system 20 correspond to different time delays between the cabinets of the speakers 30 , and also correspond to different angles of displacement.
具体地，所述多个扬声器30按照预设的弧形轨迹排列。这样，在竖直方向上，相邻的两个扬声器30之间具有一定的机械位移，相当于偏移不同角度。Specifically, the plurality of speakers 30 are arranged according to a preset arc trajectory. In this way, in the vertical direction, there is a certain mechanical displacement between two adjacent speakers 30, which is equivalent to different angles of displacement.
本实施例中，所述扬声器30优选为平板扬声器30。In this embodiment, the speaker 30 is preferably a flat panel speaker 30 .
可以理解的是，若采用的扬声器30的厚度较厚，扬声器系统20相对就会较长，由于两端扬声器30和中部扬声器30干涉，在特定的距离处会产生高频衰减。It can be understood that if the speaker 30 is thicker, the speaker system 20 will be relatively longer, and due to the interference between the speakers 30 at both ends and the speaker 30 in the middle, high-frequency attenuation will occur at a specific distance.
本实施例中采用平板扬声器30，厚度较薄，可以降低整个扬声器系统20的长度，从而可以避免扬声器30数量过多而产生高频衰减。而对于超薄电视机，采用平板扬声器30还会节省空间，设置更多的扬声器30来增加声音的辐射频率。In this embodiment, the flat panel speaker 30 is used, which is relatively thin, so that the length of the entire speaker system 20 can be reduced, thereby avoiding high-frequency attenuation caused by too many speakers 30 . For an ultra-thin TV set, the use of flat-panel speakers 30 can also save space, and more speakers 30 are provided to increase the radiation frequency of sound.
其中，若扬声器30数量过多，可通过对扬声器系统20两端扬声器30的驱动信号进行滤波处理，这种方式相当于对系统两端的扬声器30作高频衰减，也就相当于减少了系统的长度。Wherein, if the number of loudspeakers 30 is too large, the driving signals of the loudspeakers 30 at both ends of the loudspeaker system 20 can be filtered. length.
本实施例中，所述电视机具有左声道输出端和左声道输出端，所述扬声器系统20为两个，且对应连通所述电视主体10的左声道输出端和左声道输出端。左右声道输出，可以更好的提高电视机的声音输出效果。In this embodiment, the TV set has a left channel output terminal and a left channel output terminal, and the speaker system 20 is two, and the left channel output terminal and the left channel output terminal of the TV main body 10 are correspondingly connected. end. The left and right channel output can better improve the sound output effect of the TV.
进一步地，参照图3，该电视机还包括外置于所述电视主体10外的低音输出装置，所述低音输出装置与所述扬声器系统20并行输出。该低音输出装置可为低音炮，低音炮通过低通滤波，频响范围设计在0至250Hz(赫兹)，配合线阵列扬声器系统20使用，可以使整个系统频响趋于平整。其中，扬声器系统20优选采用2.1声道设计。Further, referring to FIG. 3 , the TV set also includes a bass output device outside the TV main body 10 , and the bass output device outputs in parallel with the speaker system 20 . The bass output device can be a subwoofer. The subwoofer is low-pass filtered and designed to have a frequency response range of 0 to 250 Hz (Hertz). When used with the line array speaker system 20, the frequency response of the entire system can be flattened. Wherein, the speaker system 20 preferably adopts a 2.1-channel design.
综上，本发明是利用家用电视听音环境近似近场，采用线性阵列扬声器系统20近似发出柱面波，有效减少室内反射，提高系统声压，并结合曲面电视超薄超窄要求，使电视机造型优美，提高伴音质量，保证电视机超薄的同时提高电视机的声音输出效果。To sum up, the present invention utilizes the approximate near-field listening environment of the home TV, adopts the linear array speaker system 20 to approximately emit cylindrical waves, effectively reduces indoor reflection, improves the sound pressure of the system, and combines the ultra-thin and ultra-narrow requirements of the curved TV to make the TV The machine is beautiful in shape, improves the sound quality, ensures the ultra-thin TV set and improves the sound output effect of the TV set at the same time.
