Abstract
Disclosed in the utility model is a stereo loudspeaker box that comprises a box body. A first fixed plate and a first sound-absorbing wall are arranged at one side of the box body; and a first horn unit is arranged in a semiclosed area formed by the first sound-absorbing wall and the box body. And a second fixed plate and a second sound-absorbing wall are arranged at the other side of the box body; and a second horn unit is arranged in a semiclosed area formed by the second sound-absorbing wall and the box body. Besides, helium with 0.8 atmospheric pressure is arranged in the box body. Compared with the prior art, because the two semiclosed areas are arranged and the first sound-absorbing wall and the second sound-absorbing wall have the sound-absorbing functions, the crosstalk degree of the left sound channel and the right sound channel is effectively reduced and thus the separation degree of the left sound channel and the right sound channel is substantially enhanced.
Description
Technical field
The utility model relates to audio amplifier, especially a kind of stereo speaker.
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, it is wanted directly and people's the sense of hearing is come into contacts with, and people's the sense of hearing is very sensitive, and the tone color of complex sound is had very strong resolving ability.Because people's ear is estimated the most important standard of a sound system tonequality quality just to the subjective feeling of sound, therefore, can think that the performance height of audio amplifier is to play key effect to the playing quality of a sound system.Yet along with the continuous development of Hi-Fi technique, traditional audio amplifier the situation of low frequency wave distortion or delay can occur when handling Hi-Fi with the Hi-End level signal, so can't reach to cause and allow customer satisfaction system best tonequality.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model provides a kind of stereo speaker that can strengthen stereo crosstalk, and can effectively avoid the situation of low frequency wave distortion or delay.
For achieving the above object, technical scheme provided by the utility model is: a kind of stereo speaker, comprise casing, frequency divider and binding post, side at described casing is provided with first fixed head, the first sound-absorbing wall and first loudspeaker unit, described first fixed head and casing vertical connection, the described first sound-absorbing wall and the first fixed head vertical connection, described first loudspeaker unit are arranged in the semiclosed zone of the first sound-absorbing wall and casing formation, and first loudspeaker unit is fixedlyed connected with casing; Opposite side at described casing is provided with second fixed head, the second sound-absorbing wall and second loudspeaker unit, described second fixed head and casing vertical connection, the described second sound-absorbing wall and the second fixed head vertical connection, described second loudspeaker unit is arranged in the semiclosed zone of the second sound-absorbing wall and casing formation, and second loudspeaker unit is fixedlyed connected with casing; In described casing, be provided with the helium of 0.8 atmospheric pressure.Compared with prior art, the beneficial effects of the utility model are, owing to be provided with first fixed head and the first sound-absorbing wall forms semiclosed zone, and the second semiclosed zone that forms of fixed head and the second sound-absorbing wall, and the first sound-absorbing wall and the second sound-absorbing wall have sound absorption function, the degree of crosstalk of two sound channels about effectively reducing, the separating degree of two sound channels about greatly having strengthened; Secondly, owing to be provided with the helium of 0.8 atmospheric pressure 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 improvement, described first fixed head is arranged on the lower end of audio amplifier, and described second fixed head is arranged on the upper end of audio amplifier, and described first fixed head parallels with second fixed head.This structure makes the opening in two semiclosed zones be in different directions, the degree of crosstalk of two sound channels about can further reducing.
As specializing, the described first sound-absorbing wall and the second sound-absorbing wall are the acoustical cotton product.
As specializing, described first loudspeaker unit and second loudspeaker unit are full-range loudspeaker.
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 stereo speaker that present embodiment provided, comprise casing 1, frequency divider 2 and binding post 3, side at described casing 1 is provided with first fixed head 41 and the first sound-absorbing wall 42, described first fixed head 41 and casing 1 vertical connection, described first sound-absorbing wall 42 and first fixed head, 41 vertical connections, described first loudspeaker unit 43 are arranged in the semiclosed zone of the first sound-absorbing wall 42 and casing 1 formation, and first loudspeaker unit 43 is fixedlyed connected with casing 1; Opposite side at described casing 1 is provided with second fixed head 51 and the second sound-absorbing wall 52, described second fixed head 51 and casing 1 vertical connection, described second sound-absorbing wall 52 and second fixed head, 51 vertical connections, described second loudspeaker unit 53 is arranged in the semiclosed zone of the second sound-absorbing wall 52 and casing 1 formation, and second loudspeaker unit 53 is fixedlyed connected with casing 1; Wherein, the described first sound-absorbing wall 42 and the second sound-absorbing wall 52 are the acoustical cotton product; Described first loudspeaker unit 43 and second loudspeaker unit 53 are full-range loudspeaker; In described casing 1, be provided with the helium of 0.8 atmospheric pressure.In addition, in the present embodiment, described first fixed head 41 is arranged on the lower end of audio amplifier, and described second fixed head 51 is arranged on the upper end of audio amplifier, and described first fixed head 41 parallels with second fixed head 51.This structure makes the opening in two semiclosed zones be in different directions, the degree of crosstalk of two sound channels about can further reducing.The characteristics of present embodiment neutral body sound case are, owing to be provided with first fixed head 41 and the semiclosed zone of the first sound-absorbing wall, 42 formation, and the second semiclosed zone that forms of fixed head 51 and the second sound-absorbing wall 52, and the first sound-absorbing wall 42 and the second sound-absorbing wall 52 have sound absorption function, the degree of crosstalk of two sound channels about effectively reducing, the separating degree of two sound channels about greatly having strengthened; Secondly, owing to be provided with the helium of 0.8 atmospheric pressure 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.
