Abstract
Disclosed in the utility model is a sub-bass loudspeaker box. A megaphone and a woofer are arranged in a box body; and the woofer is fixed at one end of the megaphone. Fixed arms are arranged between the megaphone and the box body; and the megaphone is fixed on the fixed arms. An echo external cylinder and an echo internal cylinder are arranged in the megaphone, wherein the echo internal cylinder is arranged in the echo external cylinder; more than one sound scattering hole is arranged at one side of the echo external cylinder; and one end, far away from the woofer, of the megaphone is provided with a shockproof ring. Besides, a reflector is arranged at the box body at the direction directly facing the woofer; and the reflector is fixedly connected with the box body. Compared with the prior art, the provided sub-bass loudspeaker box has the following beneficial effects: because the megaphone, the echo external cylinder and the echo internal cylinder are arranged near the woofer and sound scattering holes are arranged at one side of the echo external cylinder, the bass back flow can be formed, thereby increasing the bass 3D effect. Moreover, the shockproof ring is arranged at one end of the megaphone, so that the damping effect of the loudspeaker box is increased and the distortion degree of the bass can be reduced.
Description
Technical field
The utility model relates to audio amplifier, especially a kind of subwoofer 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.Wherein, woofer is a kind of of loud speaker, is the transducer that a kind of conversion electron signal becomes sound.Woofer does not generally use separately, but with high sound box with sound, middle sound box with sound cooperates forms sound system, the band vibratility of sounding, frequency is lower, makes the shock of empathizing of people's ear.Be applied to KTV, bar, broad place such as stage.Yet, continuous development along with Hi-Fi technique, the tradition audio amplifier is when handling Hi-Fi and Hi-End level signal, the situation that low frequency wave distortion or delay can occur, therefore can't reach to cause and allow customer satisfaction system best tonequality, and the existing woofer design of tradition is complicated, and manufacturing cost is higher, is unfavorable for marketing.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model provides a kind of subwoofer audio amplifier that can reduce the bass distortion factor and strengthen the 3D audio, and manufacturing cost is lower, is beneficial to marketing.
For achieving the above object, technical scheme provided by the utility model is: a kind of subwoofer audio amplifier, comprise casing, power supply and audio amplifier control circuit, described audio amplifier control circuit is arranged in the casing, in described casing, be provided with Megaphone and bass horn, described bass horn is fixed on an end of Megaphone, is provided with fixed arm between described Megaphone and the casing, and described Megaphone is fixed on the fixed arm; Be provided with echo urceolus and echo inner core in the described Megaphone, described echo inner core is arranged in the echo urceolus, described echo urceolus one side is provided with more than one diffusing sound hole, described Megaphone is provided with bump protection ring away from an end of bass horn, and described Megaphone, echo urceolus and echo inner core are fixedlyed connected with bump protection ring respectively; Be provided with reflector at described casing over against the direction of bass horn, described reflector is fixedlyed connected with casing.Compared with prior art, the beneficial effects of the utility model are, owing to be provided with Megaphone and echo urceolus, echo inner core at bass horn, and be provided with diffusing sound hole in echo urceolus one side, can form bass to reflux, increase the 3D effect of bass; And owing to be provided with bump protection ring, can strengthen the damping effect of audio amplifier, reduce the distortion factor of bass at an end of Megaphone.
As improvement, be filled with sulfur hexafluoride gas in the described casing.Owing to be provided with sulfur hexafluoride gas in casing, the air in the audio amplifier greatly reduces the vibrating diaphragm resistance of loudspeaker, and the efficient of bass and tonequality are promoted.
As specializing, described reflector is semicircle.
As specializing, the Hz-KHz of described bass horn is 16 Hz to 256Hz.
Description of drawings
Fig. 1 is a cutaway view 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 subwoofer audio amplifier that present embodiment provided, comprise casing 1, power supply 2 and audio amplifier control circuit 3, described audio amplifier control circuit 3 is arranged in the casing 1, in described casing 1, be provided with Megaphone 4 and bass horn 5, described bass horn 5 is fixed on an end of Megaphone 4, is provided with fixed arm 6 between described Megaphone 4 and the casing 1, and described Megaphone 4 is fixed on the fixed arm 6; Be provided with echo urceolus 71 and echo inner core 72 in the described Megaphone 4, described echo inner core 72 is arranged in the echo urceolus 71, described echo urceolus 71 1 sides are provided with two diffusing sound holes 711, described Megaphone 4 is provided with bump protection ring 8 away from an end of bass horn 5, and described Megaphone 4, echo urceolus 71 and echo inner core 72 are fixedlyed connected with bump protection ring 8 respectively; Be provided with reflector 9 at described casing 1 over against the direction of bass horn 5, described reflector 9 is fixedlyed connected with casing 1.Wherein, described reflector 9 is semicircle, and the Hz-KHz of described bass horn 5 is 16 Hz to 256Hz.In addition, be filled with sulfur hexafluoride gas in the described casing 1, owing to be provided with sulfur hexafluoride gas in casing 1, the air in the audio amplifier greatly reduces the vibrating diaphragm resistance of loudspeaker, and the efficient of bass and tonequality are promoted.
Compared with prior art, the advantage of subwoofer audio amplifier is in the present embodiment, owing to be provided with Megaphone 4 and echo urceolus 71, echo inner core 72 at bass horn 5, and be provided with the sound hole 711 that looses in echo urceolus 71 1 sides, can form bass and reflux, increase the 3D effect of bass; And owing to be provided with bump protection ring 8, can strengthen the damping effect of audio amplifier, reduce the distortion factor of bass at an end of Megaphone 4.
