Abstract
The utility model discloses a TV which comprises a TV casing with an audio frequency output terminal, wherein the exterior of the TV casing also comprises a power amplifier and a loudspeaker which are mutually connected in series. The input end of the power amplifier is connected with the audio frequency output terminal, and the loudspeaker is a full frequency band loudspeaker. The TV also comprises a frequency divider which is connected in series between the audio frequency output terminal and the power amplifier. The TV also comprises a frequency divider which is connected in series between the power amplifier and the loudspeaker. The bass of the TV can be compensated, and the sound playing effect of the TV can be improved by amplifying the audio frequency signals output from the TV through the power amplifier. The sound playing effect of the TV can be further improved by dividing the frequency of the audio frequency signals output from the TV through the frequency divider and playing the divided and amplified audio frequency signals respectively through an alt loudspeaker, a mediant loudspeaker and a bass loudspeaker.
Description
Technical field
The utility model relates to a kind of television set.
Background technology
At present, the moulding of television set more and more trends towards miniaturization, panelized, and what bring is reducing of loudspeaker installation site and casing thereupon, the loss of tonequality, the especially minimizing of bass composition.
The colored picture tube of cathode-ray tube TV (Cathode-Ray Tube is called for short the CRT TV) can produce picture after the influence that is subjected to the bass effect fluctuation, i.e. " microphony " phenomenon.So general CRT TV all can be done attenuation processing to bass part, improving " microphony " phenomenon, but also lost tonequality simultaneously.
Because the Frequency point of bass composition is all lower, thus very easily produce resonance with the casing of television set, just we said at ordinary times " machine shake ".In order to reduce the generation of this phenomenon, a lot of television sets its bass part of all having decayed.
In sum, the problem that in most television set, all has bass composition deficiency.
Summary of the invention
The purpose of this utility model is exactly in order to solve the problem of bass composition deficiency in the above television set, a kind of television set that can compensate bass effect to be provided.
The utility model realizes that the above-mentioned purpose scheme is: a kind of television set, comprise the housing of TV set that has audio output, and also comprise the power amplifier and the loud speaker of mutual series connection in the housing of TV set outside, input termination audio output of power amplifier.
Described loud speaker is a full range speaker.
Also comprise frequency divider, described frequency divider is connected between audio output and the power amplifier.
Also comprise frequency divider, described frequency divider is connected between power amplifier and the loud speaker.
Described loud speaker comprises woofer, Squawker and high pitch loudspeaker, the high frequency output of frequency divider connects high pitch loudspeaker by power amplifier, the medium frequency output end of frequency divider connects Squawker by power amplifier, and the low frequency output of frequency divider connects woofer by power amplifier.
Described loud speaker comprises woofer, Squawker and high pitch loudspeaker, the high frequency output termination high pitch loudspeaker of frequency divider, and the medium frequency output end of frequency divider connects Squawker, the low frequency output termination woofer of frequency divider.
The housing of TV set outside also comprises casing, and power amplifier, loud speaker place in the casing.
The housing of TV set outside also comprises casing, and power amplifier, frequency divider and loud speaker place in the casing.
Adopt the beneficial effect of above scheme:
1, adopts power amplifier that the audio signal of television set output is amplified, can compensate, improve the sound playing effect of television set its bass.
2, adopt frequency divider that the audio signal of television set output is carried out frequency division, and by high, medium and low sound loud speaker the audio signal that frequency division amplifies is play respectively, further improved the sound playing effect of television set.
3, increase casing, power amplifier, frequency divider, loud speaker etc. are placed in it, because the sound wave that front and back sent of loud speaker can be offset because of phase place is similar, especially occur in low-frequency range, casing is set can isolate the sound wave on loud speaker two sides, improves the result of broadcast of television set bass.
Description of drawings
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 is a principle schematic of the present utility model.
Embodiment
Embodiment, as shown in Figure 1, a kind of television set, comprise the housing of TV set that has audio output, the power amplifier and the loud speaker that also comprise series connection in the outside of housing of TV set, input termination audio output of power amplifier, loud speaker is a full range speaker, power amplifier amplifies the audio signal of television set output, again by loudspeaker plays.
The outside of housing of TV set also comprises frequency divider, and frequency divider is connected between audio output and the power amplifier.Loud speaker comprises woofer, Squawker and high pitch loudspeaker, frequency divider is a tri-frequency divider, audio signal is divided into high-frequency signal, intermediate-freuqncy signal and low frequency signal according to frequency, high-frequency signal is exported from the high frequency output, intermediate-freuqncy signal is exported from medium frequency output end, low frequency signal is exported from the low frequency output, its high frequency output connects high pitch loudspeaker by power amplifier, medium frequency output end connects Squawker by power amplifier, and the low frequency output connects woofer by power amplifier.
Frequency divider can also be connected between power amplifier and the loud speaker.Loud speaker comprises woofer, Squawker and high pitch loudspeaker, frequency divider is a tri-frequency divider, to be divided into high-frequency signal, intermediate-freuqncy signal and low frequency signal according to frequency through the audio signal that power amplifier amplifies, high-frequency signal is exported from the high frequency output, intermediate-freuqncy signal is exported from medium frequency output end, and low frequency signal is from the output of low frequency output, and its high frequency is exported termination high pitch loudspeaker, medium frequency output end connects Squawker, low frequency output termination woofer.
Also comprise casing, casing is positioned at the outside of housing of TV set, and described power amplifier, frequency divider and loud speaker place in the casing.
