When S101, TV are connected with bluetooth bass box, TV retains its original voice output, and current volume value is sent to bluetooth bass box;
The part-frequency point frequency of bluetooth bass box and TV loudspeaker box is sent to TV by S102, bluetooth bass box, adjusts the frequency response curve characteristic of TV after television reception to part-frequency point frequency;
S103, rated output power according to the frequency response curve characteristic of bluetooth bass box and the rated output power determination bluetooth bass box of TV, and the present output power of current volume value adjustment bluetooth bass box according to TV
As independent of the external product outside TV, when described bluetooth bass box connects TV, TV retains original speaker sound and exports, and bluetooth bass box, as the bass compensation of sound of television, reaches better tonequality.
Particularly, as shown in Figure 3, described step S101 can be refined as following steps:
S201, TV and bluetooth bass box carry out bluetooth when being connected, and TV obtains the implementor name of bluetooth bass box;
S202, judge whether to retain TV original voice output according to described implementor name;

S302, to preserve according to the frequency response curve determination bluetooth bass box of bluetooth bass box and the part-frequency point frequency of TV loudspeaker box;
S303, the part-frequency point frequency of preservation is sent to TV;
The frequency response curve characteristic of TV is adjusted after S304, television reception to part-frequency point frequency.
Its specific implementation is:
First, first determine the frequency response curve (frequency response curve) of bluetooth bass box, as shown in Figure 2, its upper cut-off frequency is f1, can determine that the part-frequency point frequency f 1(of bluetooth bass box and TV loudspeaker box generally calculates with-3db thus), see Fig. 2.When designing bluetooth bass box software, described part-frequency point frequency f 1 need be preserved.
The power-handling capability of bluetooth bass box is set: test according to reality, the rated output power supposing TV loudspeaker box under the input signal and distortion situation of a certain amplitude is P1, the TV of each size model, uniquely determine a P1, during design TV software, needing to preserve described rated output power is P1.Meanwhile, under identical input range input signal and distortion condition, the rated output power of bluetooth bass box is P2.The frequency response curve of known P1 and bluetooth bass box, can determine P2 thus.
The value of P2 can be determined in the following manner: because the frequency response curve of TV loudspeaker box and bluetooth bass box is determined, so bluetooth bass box and TV loudspeaker box amplitude corresponding relation at different frequencies is also determined, suppose that bluetooth bass box and TV loudspeaker box frequency response curve is altogether straight, so can determine P2=P1; And if bass part needs slightly lifting, then P2>P1, the value that P2 is concrete, can determine according to the actual uplift scope of bluetooth bass box frequency response curve.
Should be noted, because described bluetooth bass box joins the television set of different size possibly, suppose allly to need to mate in the TV of bluetooth bass box, the maximum of rated output power P1 is P1_MAX, in order to make TV can mutually mate with bluetooth bass box, P2 also wants corresponding adjustment, supposes that the maximum of P2 is P2_MAX, then should make P2_MAX>P1_MAX, such bluetooth bass box just can adaptive television set in need.
