Abstract
Disclosed in the utility model is a resonant sound box. A resonant horn of the resonant sound box is arranged under a high-tone loudspeaker; an arc vibration ring is arranged on the resonant horn; and the two ends of the arc vibration ring are respectively and fixedly connected with the high-tone loudspeaker and the resonant horn. Besides, a resonant sucker is arranged at the bottom of the resonant horn; the high-tone loudspeaker is fixedly connected with a bottom case; a fixed cover is arranged on the high-tone loudspeaker and the bottom of the fixed cover is provided with a metal net; and a polymeric sponge is arranged at the upper portion of the fixed cover. Compared with the prior art, because the arc vibration ring is fixedly connected between the high-tone loudspeaker and the resonant horn, the resonant horn enables the high-tone loudspeaker to be vibrated to generate high-pitched sounds and simultaneously, the resonant sucker is used to vibrate a bottom supporter to generate low-pitched sounds, thereby improving the frequency response value and the balance degree of the high-pitched and low-pitched sounds.
Description
Technical field
The utility model relates to audio amplifier, especially a kind of resonance audio amplifier.
Background technology
Along with high-speed development of science and technology, audio amplifier is as the terminal of whole sound system, and its effect is that the audio frequency electric energy is converted to corresponding sonic energy, and it is radiated the space.Audio amplifier is the extremely important part of sound system, because it is being undertaken and the signal of telecommunication is transformed into acoustical signal is directly listening to this mission critical for people's ear.And the resonance audio amplifier is a novel product, the audio amplifier that does not have loudspeaker, extremely rare on the market, the appearance of resonance audio amplifier, its aim is exactly the limitation of common audio amplifier audio of breaking traditions, because the transaudient of common audio amplifier is to reach the audio effect through loudspeaker level concussion transfer of air, and certain limitation directive property is arranged; The resonance audio amplifier just can be not like this, and the resonance audio amplifier can be propagated with 360 ° of frequencies.Yet the frequency range of the resonance audio amplifier pronunciation in existing being provided with is very limited, and it is strong more that bass designs, and high pitch is influenced by it just, can't reach the full frequency band pronunciation, and audio is not good.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model is to improve frequency response values height, the good resonance audio amplifier of the height sound degree of balance, and simple in structure, low cost of manufacture, volume little, be easy to carry about with one.
For achieving the above object, technical scheme provided by the utility model is: a kind of resonance audio amplifier, comprise drain pan, loudspeaker, resonance loudspeaker, power supply and audio amplifier control circuit, described power supply and audio amplifier control circuit are arranged on drain pan, described resonance loudspeaker are arranged on the loudspeaker lower end, being provided with the circularoscillations circle on described resonance loudspeaker, fixedlys connected with the resonance loudspeaker with loudspeaker respectively in the two ends of described circularoscillations circle; Be provided with the resonance sucker in described resonance loudspeaker bottom; Described loudspeaker is fixedlyed connected with drain pan, is provided with fixed cover on described loudspeaker, and the bottom of described fixed cover is a wire netting, and the top of described fixed cover is polyurethane sponge.Compared with prior art, the beneficial effects of the utility model are, owing between loudspeaker and resonance loudspeaker, be fixedly connected with the circularoscillations circle, resonance loudspeaker vibration loudspeaker earlier send high pitch, send bass by resonance sucker vibration bottom support thing simultaneously, improved the frequency response values and the height sound degree of balance; Secondly, be provided with fixed cover,, can play the counterweight effect, avoid audio amplifier self vibration to produce and disturb because the fixed cover bottom is a weight wire netting greatly at loudspeaker; Once more,, can avoid dust and foreign material to enter diffusing sound hole, ensure the resonance audio because the top of fixed cover is provided with polyurethane sponge.
As specializing, described circularoscillations circle is an alumiaum article.As specializing, described circularoscillations circle is the titanium product.
As specializing, the bottom of described drain pan is an opening.Because the bottom of drain pan is an opening, the resonance sucker of resonance loudspeaker passes opening and is connected with supporting bracket.
As specializing, on described drain pan, be provided with fixed leg, described loudspeaker is fixedly mounted on the fixed leg by screw.
As improvement, on described drain pan, be provided with audio frequency input and output interface.
As improvement, on described drain pan, be provided with SD card card reading slot.
As improvement, on described drain pan, be provided with usb connecting port.
Description of drawings
Fig. 1 is a three-dimensional installation diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figure 1, a kind of resonance audio amplifier that present embodiment provided, comprise drain pan 1, loudspeaker 2, resonance loudspeaker 3, power supply and audio amplifier control circuit, described power supply and audio amplifier control circuit are arranged on drain pan 1, described resonance loudspeaker 3 are arranged on loudspeaker 2 lower ends, being provided with circularoscillations circle 32 on described resonance loudspeaker 3, fixedlys connected with resonance loudspeaker 3 with loudspeaker 2 respectively in the two ends of described circularoscillations circle 32; Be provided with resonance sucker 31 in described resonance loudspeaker 3 bottoms; Described loudspeaker 2 is fixedlyed connected with drain pan 1, is provided with fixed cover 4 on described loudspeaker 2, and the bottom of described fixed cover 4 is a wire netting 41, and the top of described fixed cover 4 is polyurethane sponge 42.Wherein, described circularoscillations circle 32 is an alumiaum article; And the bottom of described drain pan 1 is an opening, because the bottom of drain pan 1 is an opening, the resonance sucker 31 of resonance loudspeaker 3 passes opening and is connected with supporting bracket; Also be provided with fixed leg 5 on described drain pan 1, described loudspeaker 2 is fixedly mounted on the fixed leg 5 by screw.In addition, on described drain pan 1, also be provided with audio frequency input 61 and output interface 62; On described drain pan 1, be provided with SD card card reading slot 7; On described drain pan 1, be provided with usb connecting port 8.
The advantage of miniature plate audio amplifier is in the present embodiment, owing between loudspeaker 2 and resonance loudspeaker 3, be fixedly connected with circularoscillations circle 32, resonance loudspeaker 3 vibration loudspeaker 2 earlier send high pitch, send bass by resonance sucker 31 vibration bottom support things simultaneously, improved the frequency response values and the height sound degree of balance; Secondly, be provided with fixed cover 4,, can play the counterweight effect, avoid audio amplifier self vibration to produce and disturb because fixed cover 4 bottoms are weight wire netting 41 greatly at loudspeaker 2; Once more,, can avoid dust and foreign material to enter diffusing sound hole, ensure the resonance audio because the top of fixed cover 4 is provided with polyurethane sponge 42.
