Abstract

The utility model discloses a sound of a television, which comprises a sound system arranged in the television. The sound system comprises a box which is provided with a loud speaker group; a phase inverting hole is arranged on the box; the phase inverting hole is formed by a section of tube; the top of one end of the phase inverting hole is provided with a positioning plate. The box can be a sound box which is singly arranged in the television; a shell of the television also can be made into a box. Compared with the prior art, the utility model has lower resonance frequency through using the box with phase inverting hole, so the low frequency of the box can get effective extending; the sound pressure also gets improvement; the middle and low sounds are reverted clearly and naturally so as to improve the tone of the whole television; the utility model overcomes the problem that the traditional televisions do not have excellent tone so as to gain ideal tone effect. Furthermore, the phase inverting hole produces air stream when in work so as to be beneficial to strengthen the heat radiating of the television.

Description

Television acoustics

Technical field

The utility model relates to a kind of television acoustics, relates in particular to a kind of sound system that is used for television set with the paraphase structure.

Background technology

The tonequality that improves the TV product is the research and development target of each producer, now general television set is only sounded at the inner loud speaker of installing of the casing of sealing, perhaps use a simple casing that loud speaker is enclosed in wherein and sound, the sound tonequality of coming out like this is generally all poor.

The utility model content

The utility model is the technical problem that is difficult to reach preferable effect for the tonequality that solves existing television set, and a kind of television acoustics that utilizes paraphase hole to improve tonequality is provided.

For addressing the above problem, the technical solution of the utility model is a kind of television acoustics of structure, comprises the sound system of being located in the television set, and sound system comprises the casing that is provided with set of speakers, and casing is provided with paraphase hole.

Wherein, described paraphase hole is formed by one section tubing, and an end top of paraphase hole is provided with location-plate.

The utility model is optimized design:

Among first embodiment, casing is the audio amplifier of being located in the television set, and paraphase hole is located on this audio amplifier.

Among second embodiment, casing is the casing of television set, and paraphase hole is located on the casing.

Compared with prior art, the utility model has the casing of paraphase hole by use, its resonance frequency can be lower, so the low frequency of this casing can effectively be extended, and acoustic pressure also obtains to improve, bass reduces clearly and natural in making, thereby improved the tonequality of whole television set, overcome the not good problem of conventional television tonequality, thereby obtained desirable acoustical quality in addition, because paraphase hole can produce air-flow when work, this also will help strengthening the heat radiation of television set itself.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further, wherein:

Fig. 1 is the utility model first example structure schematic diagram;

Fig. 2 is the utility model second example structure schematic diagram.

Embodiment

As shown in Figure 1, this figure is for the basic structure of the utility model first embodiment, a kind of television acoustics, comprise the sound system of being located in the television set 5, sound system comprises the casing that set of speakers 1 is installed, this casing is provided with paraphase hole 2, and paraphase hole 2 is formed by one section tubing, and an end top of paraphase hole 2 is provided with location-plate 6.The cross-sectional area of paraphase hole 2 and length and the position offered thereof are according to the space size and the Adjusting Shape of casing.

Among first embodiment, casing is the audio amplifier 3 that is packed in the television set 5, when using built-in speaker 3, selects for use optimal cross-section paraphase hole 2 long-pending and length to install according to audio amplifier 3 size and location on built-in speaker 3, to obtain best acoustical quality.Among this embodiment, be provided with two symmetrically arranged audio amplifiers 3 in the television set 5, two audio amplifiers 3 are fixed on the front panel of picture tube 7 both sides television sets 5 of television set 5, are fixed with set of speakers 1 on the antetheca of audio amplifier 3, and paraphase hole 2 is located on the antetheca of set of speakers 1 below audio amplifier 3.

As shown in Figure 2, this figure is for the basic structure of the utility model second embodiment, built-in speaker 3 is not used in television set 5 inside, the casing 4 of whole television set 5 is considered as the casing of sound system, use the audio amplifier design principle, casing 4 rear portions at television set 5 are provided with a paraphase hole 2, and calculate best paraphase hole 2 cross-sectional areas and length according to the space size and the shape of casing 4, utilize casing 4 to obtain best sounding effect.Among this embodiment, 1 group of set of speakers is fixed on the front panel of picture tube 7 both sides television sets 5 of television set 5.

The utility model, use has the casing of paraphase hole, its resonance frequency can be lower, therefore the low frequency of this casing can effectively be extended, acoustic pressure also obtains to improve, and bass reduces clearly and natural in making, thereby has improved the tonequality of whole television set, overcome the not good problem of conventional television tonequality, thereby obtained desirable acoustical quality.In addition, because paraphase hole can produce air-flow when work, this also will help strengthening the heat radiation of television set itself.
