The surface of the box body 101, which is tightly attached to the side plate 202, is a contact surface, and the area of the side plate 202 is 40-70% of the area of the contact surface; the support 30 is fixed on one surface of the bottom plate 201 far away from the side plate 202, a fixing portion 2013 is further arranged on the bottom plate 201, and the support 30 and the bottom plate 201 are fixed by the fixing portion 2013.

As shown in fig. 1 to 4, the first side plate 2021 and the second side plate 2022 are fixed on the bottom plate 201, and a placing space 203 is formed therebetween. The cabinet 101 resonates during playback of the audio 10, and the resonances are particularly pronounced at low frequencies. The box body 101 is generally made of wood, the first side plate 2021, the second side plate 2022 and the bottom plate 201 are preferably made of metal materials, the box body 101 is placed in the placing space 203, the box body 101 is placed on the bottom plate 201, the bottom of the box body 101 contacts with the bottom plate 201, the first side plate 2021 and the second side plate 2022 are fixed to two opposite sides of the box body 101, the first side plate 2021 and the second side plate 2022 are tightly clamped with the two opposite sides of the box body 101, and the thicknesses of the first side plate 2021 and the second side plate 2022 are different from the thickness of the box body 101 on the contact surface;

most of the musical instruments in the symphony orchestra consist of string music and orchestra, the string music is produced by the resonance of strings and wood cavities, and the orchestra is produced by metal musical instruments. On the basis of keeping the original wood box 101, the first side plate 2021 and the second side plate 2022 which are made of metal materials and have different thicknesses are properly clamped on the two sides of the box 101, so that the resonance-free sound production system becomes a mixture of metal and wood, the metal materials and the wood have different resonance frequencies, resonance emitted by the wood cannot enable the metal materials to resonate, but can be absorbed and offset by the metal materials, when the box 101 resonates, the resonance is conducted to the first side plate 2021 and the second side plate 2022, the first side plate 2021 and the second side plate 2022 made of the metal materials can absorb the resonance, and the box 101 cannot continuously conduct the resonance, so that the resonance of the box 101 is eliminated; the first side plate 2021 and the second side plate 2022 can destroy the natural resonant frequency of the box 101, so that the resonance of the box 101 is reduced to the outside of the playing frequency, the resonance interference of the box 101 to the playing is avoided, the sound of the sound box 10 is closer to the reality, and the real sound quality can be directly reflected. The resonance-free sounding system is made of wood and metal materials, has the wonderful and orchestral vigor of string music, and avoids resonance of a single material due to the combination of the two materials.

When the sound box 10 plays low-frequency music, the resonance of the box body 101 is particularly obvious, and when the sound box 10 plays high-frequency music, the resonance of the box body 101 is not obvious; when the area of the side plate 202 is too large, the coverage area of the contact surface is large, high-frequency vibration of the box body 101 is influenced, and therefore played music is not high enough and sound is not clear enough; when the area of the side plate 202 is too small, the coverage area of the contact surface is small, and low-frequency resonance cannot be effectively inhibited. In summary, the side plate 202 having an area of 40% to 70% of the contact surface area is a preferable design that can suppress resonance of the case 101 and does not affect high-frequency sound emission through a plurality of tests.

The shape of the resonance-free sounding body 20 is as follows: the bottom plate 201 is an isosceles trapezoid, the first side plate 2021 and the second side plate 2022 are respectively fixed to the bottom plate 201 along one waist edge of the isosceles trapezoid, the first side plate 2021 is provided with a first end 20211 and a second end 20212, the second side plate 2022 is provided with a third end 20221 and a fourth end 20222, the first end 20211 is opposite to the third end 20221, the second end 20212 is opposite to the fourth end 20222, the first end 20211 and the third end 20221 correspond to two ends of a long edge of the isosceles trapezoid, the second end 20212 and the fourth end 20222 correspond to two ends of a short edge of the isosceles trapezoid, and a distance between the first end 20211 and the third end 20221 is greater than a distance between the second end 20212 and the fourth end 20222.
