Description
Technical field
The present invention relates to slim audio amplifier, specifically a kind ofly form, take back the shape conduit, can be built in the slim integrated loudspeaker system of panel TV system by two loudspeaker units.
Background technology
The speaker system of panel TVs such as LCD, PDP design now, undersized panel TV generally adopts the loudspeaker unit of two full frequency bands, is cavity with the tv shell internal volume, forms stereo or virtual surround system; The large scale panel TV then adopts a pair of speaker system, and this system generally is made up of a medium and low spectrum loudspeaker unit and a high pitch loudspeaker unit.First kind of scheme lower tone is fit to the design of low side panel TV; Second kind of scheme acoustical sound, but because the cavity volume of its speaker system is subject to the overall structure of panel TV, add the restriction of loudspeaker unit itself, and the low frequency expansion is relatively poor.
Summary of the invention
The purpose of this invention is to provide that a kind of low frequency expansion is good, the integrated built-in speaker of carrying pipe, to solve panel TV with the speaker system structure is thin, cavity volume is little, LF-response is poor, the shrivelled technical problem such as not plentiful of sound.
The technical scheme that provides according to invention, the woofer unit that on airtight voice box casing, is provided with, it is characterized in that: in voice box casing, be provided with conduit, the sound opening that goes out of conduit is in a side near the woofer unit, the sound opening that advances of conduit is in a side away from the woofer unit, the sound opening that advances of conduit is communicated with the internal cavity of voice box casing, conduit go out the sound opening towards with the woofer unit towards consistent, conduit go out sound opening and extraneous air conducting.
The sound opening that goes out of conduit is arranged on and is under the woofer unit and near a side of woofer unit, and the sound opening that advances of conduit is arranged on and is under the woofer unit and away from a side of woofer unit.The next door of conduit is provided with the medium and high pitch loudspeaker unit, and the medium and high pitch loudspeaker unit is arranged in the airtight cavity of voice box casing.Medium and high pitch loudspeaker unit and conduit be arranged in parallel.Voice box casing is provided with the installing hole with shockproof hole pad.
Low frequency expansion of the present invention is good, and it is thin with the speaker system structure to have solved panel TV, and cavity volume is little, and LF-response is poor, the shrivelled technical problem such as not plentiful of sound.

Embodiment
As shown in the figure: the woofer unit 2 that on voice box casing 1, is provided with, in voice box casing 1, be provided with the conduit 9 that two ends are communicated with, the sound opening 4 that goes out of conduit 9 is in a side near woofer unit 2, the sound opening 8 that advances of conduit 9 is in a side away from woofer unit 2, the sound opening 8 that advances of conduit 9 is communicated with the internal cavity 7 of voice box casing 1, internal cavity 7 also is communicated with woofer unit 2, conduit go out sound opening 4 towards consistent with woofer unit 2, conduit go out sound opening 4 and extraneous air conducting.
The sound opening 4 that goes out of conduit 9 is preferably disposed on and is under the woofer unit 2 and near a side of woofer unit 2, and the sound opening 8 that advances of conduit 9 is preferably disposed on and is under the woofer unit 2 and away from a side of woofer unit 2.One side of conduit 9 also can be provided with medium and high pitch loudspeaker unit 6, and medium and high pitch loudspeaker unit 6 is arranged in the airtight cavity 5 in the internal cavity 7 of voice box casing 1.Medium and high pitch loudspeaker unit 6 preferably be arranged in parallel with conduit 9.Voice box casing 1 is provided with the installing hole 3 with shockproof hole pad.
As mentioned above, the conduit 9 that the present invention is provided with in voice box casing 1, conduit 9 roots are directly towards a cavity, with 2 conductings of circular woofer unit, form the inner chamber body of a carrying pipe, with the airtight cavity 5 at 6 places, rectangle medium and high pitch loudspeaker unit be that physics separates.Airtight cavity 5 is positioned at the next door of back-shaped conduit 9.
The cabinet design of general speaker system, its conduit bottom opening is towards all pointing to the woofer unit, the present invention is then by reverse open design, utilize the self structure of audio amplifier cavity 1, in limited slim body structure, the length and the bore of conduit 9 have greatly been prolonged, increased the internal volume of cavity, be specially except that the length and bore of conduit 9 bodies, made full use of the gap that conduit 9 both sides and audio amplifier cavity inner wall form, two new conduits have been equivalent to increase, in addition since the position of conduit 9 be positioned at woofer unit 2 under, make the cavity volume of entering sound opening 8 places of whole conduit 9 be fully utilized, be equivalent to increase the internal volume of cavity, when the vibrational system that constitutes with conduit 9 in the audio amplifier cavity during at low frequency generation resonance, after the acoustic design of optimizing, the low-frequency sound wave of the anti-phase radiation of loudspeaker unit, from conduit 9, radiate expeditiously, add because the part of close woofer unit 2, thereby can improve the LF-response of whole audio amplifier, expand low-frequency range, make whole speaker system low frequency get a promotion and expand, and the acoustic centre of source is also consistent more, improves subjective hearing effect.Because the 6 one-tenth asymmetric geometries in woofer unit 2 and medium and high pitch loudspeaker unit help the installation of this integrated built-in speaker in panel TV, both can laterally install in addition, also can vertically install, increase the Scheme Selection degree.
Referring to Fig. 1 and Fig. 2, the present invention includes voice box casing 1, and be installed in woofer unit 2 on the housing, the medium and high pitch loudspeaker unit 6 of band frequency dividing circuit, be provided with installing hole 3 at voice box casing 1 with shockproof hole pad, be out of shape the conduit 9 that extends into by voice box casing 1, be positioned at the inside of voice box casing 1, be woofer unit 2 under the position, and conduit 9 go out sound opening 4 towards consistent with woofer unit 2 and medium and high pitch loudspeaker unit 6, conduit 9 go out sound opening 4 and extraneous air conducting, conduit 9 advance sound opening 8 towards a side away from woofer unit 2, form the cavity 7 of carrying pipe 9, the cavity 7 of this carrying pipe 9 is communicated with the cavity at 2 places, woofer unit, can regard same cavity 7 as, another alt unit 6 is positioned at another airtight cavity 5, this airtight cavity 5 is formed by voice box casing 1 distortion extension equally, can regard airtight cavity 5 as and place cavity 7 inside.After woofer unit 2 process acoustic design, when consistent, can strengthen low frequency significantly with its positive radiative acoustic wave phase place.Can reduce simultaneously near the amplitude distortion of the loud speaker 2 of low frequency playback lower limit.Make the power that bears of this woofer unit 2 strengthen.Reduce the design difficulty of loudspeaker unit.And the medium and high pitch loudspeaker unit 6 and airtight cavity 5 of band frequency dividing circuit, formed one and closed the case system, make high pitch obtain expanding, and its Mid Frequency has not been disturbed by the standing wave of woofer unit 2 radiation can, make the Mid Frequency value improve, and improve its lower frequency limit.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example, those skilled in the art, and in essential scope of the present invention, the variation of making, remodeling adds or replacement, also belongs to protection scope of the present invention.
The present invention can do simple mirror image and handle as above-mentioned principle and structure, can obtain two integrated built-in speakers of taking back the shape conduit of mirror-symmetrical, partners stereo or virtual surround system.
