Wherein, in accompanying drawing, corresponding reference is, 1- soundboard, 2- sound beam, 3- audio amplifier framework, 4- the first sound beam, 5- Two grooves, 6- first groove, 7- the second sound beam.

Specific embodiment

Describe the technical solution of the utility model below in conjunction with drawings and Examples in detail, to technical side of the present utility model Case makes clearly complete explanation, so that those skilled in the art realize this practicality on the basis of description of the present utility model New technical scheme, it should be noted that the technical scheme in following examples is only preferred technology of the present utility model Scheme, on the premise of without departing from innovation and creation of the present utility model design, any improvement that this utility model is done and Modification still falls within protection domain of the present utility model.

Embodiment

As illustrated in fig. 1 and 2, a kind of an ancient plucked stringed instrument loudspeaker box structure, including soundboard 1, sound beam 2 and audio amplifier framework 3；Described audio amplifier frame Frame 3 is the closure arcuate structure of both-side opening；The side of described audio amplifier framework 3 is provided with more than one first groove 6；Described The opposite side of audio amplifier framework 3 is provided with more than one second groove 5；Described sound beam 2 includes more than one first sound beam 4 He More than one second sound beam 7；The two ends of each the first sound beam 4 are connected with the side of audio amplifier framework 3 by two the first grooves 6 Connect；The two ends of each the second sound beam 7 are connected with the opposite side of audio amplifier framework 3 by two the second grooves 5, two described soundboards 1 is connected with the both sides sealing of audio amplifier framework 3.

Further improvement is that the cross section of described first groove 6 and the second groove 5 is " l " shape structure.

As shown in figure 1, the size of soundboard 1 is matched with the size of audio amplifier framework 3, audio amplifier framework 3 is closing of both-side opening Close irregular arcuate structure, soundboard 1 covers the both sides up and down in audio amplifier framework 3, two soundboards 1 pass through fluid sealant and audio amplifier frame The both sides sealing up and down of frame 3 connects.B-b section in Fig. 1 is as shown in Fig. 2 the second sound beam 7 and the first sound beam 4 are thick middle The thin strip structure in two ends, the left end of the second sound beam 7 is stuck on the left end of audio amplifier framework 3 by the second groove 5 of left end, the The right-hand member of two sound beams 7 be stuck on audio amplifier framework 3 by the second groove 5 of right-hand member it is preferable that the second sound beam 7 pass through fluid sealant with Second groove 5 at two ends bonds；The left end of the first sound beam 4 is stuck on the left end of audio amplifier framework 3 by the first groove 6 of left end, The right-hand member of the first sound beam 4 is stuck on audio amplifier framework 3 by the first groove 6 of right-hand member it is preferable that the first sound beam 4 passes through fluid sealant Bond with first groove 6 at two ends；The upper side and lower side of audio amplifier framework 3 is sealed by two soundboards 1, surrounds audio amplifier.In Fig. 1 The left side of a-a is provided with the schematic diagram of soundboard 1 for audio amplifier framework 3, and in Fig. 1, the right side of a-a is on the audio amplifier framework 3 within audio amplifier Sound beam 2 schematic diagram；The upper side and lower side of audio amplifier framework 3 is sealed by two soundboards 1, and same employing seals glue bond, Thus the integral seamless gap realizing whole soundboard 1 ensures to improve the service life of soundboard 1 while tonequality.Preferably, the first sound The thickness at beam 4 two ends is identical, and the thickness at the second sound beam 7 two ends is identical, and the section of the second groove 5 and the first groove 6 is that " l " shape is tied Structure；The depth of the second groove 5 is identical with the thickness at the two ends of the second sound beam 7, the depth of the first groove 6 and the two of the first sound beam 4 The thickness at end is identical, so that two soundboards 1 of audio amplifier framework both sides about 3 are by the first sound beam 4, the second sound beam 7 and audio amplifier Framework 3 is seamless to be sealed, and reaches preferable sound transmission effect it is ensured that tonequality.Preferably, first groove at left and right two ends 6 and second the depth of groove 5 can be determined according to the thickness of the first sound beam 4 and the second sound beam 7.
