Abstract
The utility model discloses a speaker including a box body and loudspeaders disposed on the box body, characterised that: two jucntion boxes connecting with the loudspeaders are equiped on the box body; the loudspeaders having an althorn, a mediat horn and a bass horn are divided into two groups, each of which are equiped on both sides of a sound insulation board disposed within the box body; a diverter swich is provided between the two groups of the loudspeaders; and a leading sound hole 1 and a leading sound hole 2 disposed on two sides of the sound insulation board, respectively, are equiped on the box body. The utility model is capable of connecting two power amplifiers on a single speaker simultaneously with one power amplifier playing music, while the oter power amplifier playing sound of a singer, thus scream generated by mixing sound of the singer with the music is avoided, and load of a single power amplifier is reduced. The diverter swich can make the user more convenient to use only one power amplifier when only music is required, once turn on the diverter swich, simultaneously playing of a upper and a lower horns is achieved.
Description
Technical field
The utility model relates to a kind of audio amplifier, especially a kind of audio amplifier of two power amplifiers of can plugging into simultaneously.
Background technology
At present, the audio amplifier on the market generally all is to support a power amplifier, promptly at the back side of audio amplifier a terminal box only is set, and the lead-out terminal of power amplifier is connected with this terminal box, if just can not realize when plugging into two power amplifiers simultaneously.Raising along with people's quality of life, requirement to sound equipment is also improving constantly, especially when OK a karaoke club ok sings, wish that sound equipment can have tamber effect preferably, and good tone color comes from the stereo set of high-quality, for a cover karaoke OK system, audio amplifier is the most important terminal equipment of Karaoke, and the structural design of audio amplifier directly affects the quality of speaker quality.Singer's sound and background music are propagated in same sound box, cause interference, have directly had influence on the effect of sound equipment, and voice and musical sound are easy to generate shriek with a power amplifier.Simultaneously, existing audio amplifier is generally a pair of, and floor space is big, and is for the little family of script area, not attractive in appearance especially.
Summary of the invention
The utility model purpose is to address the above problem, and provides a kind of interference little, and sound effect is good, the audio amplifier of two power amplifiers of can plugging into simultaneously.
The utility model for achieving the above object, the technical scheme that is proposed is:
A kind of audio amplifier comprises casing, is located at the loud speaker on the casing, it is characterized in that: described casing is provided with two terminal boxes that are connected with loud speaker; Wherein loud speaker is divided into two groups, is in the sound panel both sides respectively; Sound panel is arranged in the casing;
Be provided with diverter switch between described two groups of loud speakers;
Described casing is provided with voice guide hole I and the voice guide hole II that is in the sound panel both sides respectively;
Described loud speaker is loudspeaker I, mediant trumpet I and bass horn I for one group, and another group is loudspeaker II, mediant trumpet II and bass horn II;
Described loudspeaker I, mediant trumpet I, loudspeaker II and mediant trumpet II are arranged on the casing front panel;
Described bass horn I and bass horn II are arranged on the side panel of casing;
Described voice guide hole II is arranged on the casing front panel; Described voice guide hole I is arranged on the box back surface plate.
The beneficial effect that the utility model had is: by two terminal boxes that are connected with loud speaker are set on casing, realized the function that on an audio amplifier, is connected with two power amplifiers, can make a power amplifier playing back music, another plays singer's sound, the shriek that has produced when having avoided voice and musical sound to mix has also reduced the load of single power amplifier.The setting of change over switch can make the user more convenient, when only needing music appreciating, can only use a power amplifier playing back music, connects diverter switch and can realize the synchronous broadcast of loudspeaker up and down.Because the loud speaker branch is set as two groups, and is provided with sound panel, the audio of music and voice can be carried out distinct encapsulation process in audio amplifier, solved voice and musical sound and in same casing, disturbed and influence acoustic problem.Simultaneously, use audio amplifier of the present utility model also to reduce floor space.
Description of drawings
Fig. 1 is the front view of the utility model audio amplifier embodiment;
Fig. 2 is the A-A view among Fig. 1;
Fig. 3 is the right view of the utility model audio amplifier embodiment;
Fig. 4 is the rearview of the utility model audio amplifier embodiment;
Fig. 5 is an operating state line graph of the present utility model.
Embodiment
Also in conjunction with the accompanying drawings the utility model is done detailed description below by specific embodiment.
As shown in Figure 1, loud speaker adopts loudspeaker, mediant trumpet and bass horn in the present embodiment.Loudspeaker I4 and mediant trumpet I3 are arranged on the front panel of casing 1, with speaker combination of bass horn I9 composition shown in Figure 3.Loudspeaker II7 and mediant trumpet II5 are arranged on the front panel of casing equally, form another speaker combination with bass horn II10 shown in Figure 3.By sound panel shown in Figure 22 it is isolated fully in the middle of two groups of loud speakers, be independent of each other.
Fig. 2 is the A-A view of Fig. 1, and as shown in Figure 2, casing 1 front panel is provided with voice guide hole II6 among the figure, and the box back surface plate is provided with voice guide hole I15, and voice guide hole I15 and voice guide hole II6 are in sound panel 2 both sides respectively.Voice guide hole I15 and voice guide hole II6 can radiate the sound wave of speaker awl basin back side radiation in casing, improve the efficient of audio amplifier.
See Fig. 4, Fig. 5, Fig. 4 is the rearview of present embodiment, and casing 1 backplate is provided with terminal box I13, terminal box II14 and diverter switch 8.As shown in Figure 5, loudspeaker I4, mediant trumpet I3 are connected with power amplifier I16 by terminal box I13 with bass horn I9 three and after connecing.Equally, loudspeaker II7, mediant trumpet II5 are connected with power amplifier II17 by terminal box II14 with bass horn II10 three and after connecing.Be connected by diverter switch 8 between terminal box I13 and the terminal box II14.
The course of work of the present utility model: when OK a karaoke club ok, diverter switch 8 is an off-state, after background music is handled by power amplifier I16, be transferred to loudspeaker I4, mediant trumpet I3 and bass horn I9 by terminal box I13, equally, after power amplifier II17 handles singer's sound, and be transferred to loudspeaker II7, mediant trumpet II5 and bass horn II10 respectively, thereby realize the processing respectively and the broadcast of background music and singer's sound by terminal box II14; When music appreciating only, connect diverter switch 8, but two groups of loud speaker synchronous playing up and down at this moment, only need to use power amplifier I16 playing back music.
