Operation principle of the present utility model is:
When the output low frequency power of the low-frequency power amplifier of audio-frequency power amplifier puts on woofer 7, the loudspeaker unit of woofer 7 realizes electroacoustic conversion, when the vibrating diaphragm of the loudspeaker unit of woofer 7 is to the first bass casing 1 direction vibration, compress the air in the first bass casing 1, air pressure thus in the first bass casing 1 is greater than atmospheric pressure, force air through the first phonocatheter 3 and the first bass outlet 4, be transferred to ambient air, simultaneously, atmospheric pressure in second bass casing 2 is lower than atmospheric pressure, force the air of air through the second bass outlet 6 and the second phonocatheter 5, be transferred in the second bass casing 2.Otherwise, when the vibrating diaphragm of the loudspeaker unit of woofer 7 is to the second bass casing 2 direction vibration, have compressed the air in the second bass casing 2, the atmospheric pressure in the second bass casing 2 is made to be greater than ambient air pressure, the air in the second bass casing 2 is forced to be transferred to ambient air through the second phonocatheter 5 and the second bass outlet 6, simultaneously, atmospheric pressure in first bass casing 1 is less than ambient air pressure, forces the air of ambient air to be transferred in the first bass casing 1 through the first bass outlet 4 and the first phonocatheter 3.Obtain strong enhancing at so repeatedly reciprocal process medium and low frequency information stream, thus obtain simple and honest, shock, whippy bass sound wave.In addition, when the full range power stage of audio-frequency power amplifier puts on the loudspeaker unit of medium and high pitch loudspeaker 10, because these loudspeaker units are all that loudspeaker unit vibrating diaphragm is outwards installed, just the alt sound wave of generation is directly radiated and hears space, so just can obtain clear lucid and lively alt sound, especially, time by an angle to each other for two loudspeaker units being arranged in alt casing 9, two loudspeaker unit radiation directions are different, and sound field effect is greatly improved.
If bar shaped audio amplifier is the first bass casing 1 when being formed side by side with one or more second bass casing 2, when the vibrating diaphragm of the loudspeaker unit of each woofer 7 vibrates in the same direction, the atmospheric pressure in a casing is only had to be less than ambient air pressure in each casing, atmospheric pressure in other casings is all greater than ambient air pressure, forces the phonocatheter of air in respective casing and bass outlet delivery to ambient air; Meanwhile, atmospheric pressure is less than the casing of ambient air pressure, and the air of ambient air is transferred in this casing through the bass outlet of this casing and phonocatheter.Obtain strong enhancing at so repeatedly reciprocal process medium and low frequency information stream, thus obtain simple and honest, shock, whippy bass sound wave.In addition, when the full range power stage of audio-frequency power amplifier puts on the loudspeaker unit of medium and high pitch loudspeaker 10, because these loudspeaker units are all that loudspeaker unit vibrating diaphragm is outwards installed, just the alt sound wave of generation is directly radiated and hears space, so just can obtain clear lucid and lively alt sound, especially, time by an angle to each other for two loudspeaker units being arranged in alt casing 9, two loudspeaker unit radiation directions are different, and sound field effect is greatly improved.
Integral type bar shaped audio amplifier of the present utility model, have employed the bass casing sound physical properties structure of innovation, and be organically combined in a bar shaped casing with alt casing, abandon very large bad subwoofer of laying, only use a bar shaped audio amplifier, just achieve the high-quality gamut audio frequency comprising bass to play, also reduce manufacturing cost simultaneously, decrease the use of material.
