Description

Anti-resonance sound box

Technical Field

The invention relates to sound equipment, in particular to a sound box.

Background

The sound of the sound box is mainly determined by three elements, namely a loudspeaker unit, a box body structure design and a frequency divider, and the active sound box also needs to comprise power amplifier equipment; when music is actually played, the box body is driven to resonate in the sound transmission process, so that the transmitted sound is not clear and pure; therefore, many sound box manufacturers select a wood structure to manufacture sound boxes, and because the wood structure is thick and heavy and has high density, resonance and box sound can be effectively controlled, sound pollution is effectively reduced, and pure sound quality is obtained; however, the so-called wood structure is not a natural solid wood material, but a synthetic density fiberboard; in addition, many sound boxes are made of concrete; therefore, theoretically, what material is used is feasible as long as the box body is firm enough and thick enough so as not to generate resonance; however, the existing sound box sacrifices portability in order to ensure the thickness and the gravity of the sound box, and is greatly limited in moving and carrying; because the structure of audio amplifier is comparatively accurate, need lightly to take when the transport, nevertheless because its quality is overweight, accomplish lightly to take and lightly to put the degree of difficulty great, consequently appear colliding with very easily during the transport, and in case collide with and will cause the audio amplifier to appear crack or dark wound easily to influence the damping of box, resonance effect, cause the tone quality of audio amplifier impaired by a wide margin.

Disclosure of Invention

In view of the above problems, the present invention provides an anti-resonance sound box, which has a novel structure and a unique principle, can provide a box with sufficient firmness and thickness, effectively reduces resonance during music playing, and can be conveniently transferred and carried.

The invention has the beneficial effects that: after the anti-vibration wall is filled with anti-vibration liquid, the weight of the box body becomes heavy, the thickness of the anti-vibration wall is increased, and the box body becomes thick, heavy and firm; compared with the traditional box body, the anti-vibration wall is filled with anti-vibration liquid, so that the equivalent density of the anti-vibration wall is greater than that of the traditional wooden box body, when the loudspeaker unit plays sound and vibrates, the anti-vibration wall can effectively reduce resonance, and the tone quality is guaranteed.

Besides the vibration damping effect can be improved, the vibration-proof liquid in the structure can be flexibly filled or extracted; therefore, when the sound box needs to be carried and transferred, for example, when a user selects and purchases the sound box, a merchant sends the sound box to the door, the anti-vibration liquid can be extracted out firstly, so that the quality of the sound box is greatly reduced, and the anti-vibration liquid is injected when the installation position is relatively fixed; this mode of operation can make things convenient for porter's transfer, transportation, and realization that can be convenient is gently taken lightly, is difficult for causing the box to collide with to the dark wound that appears in the handling has been avoided, and then has effectively guaranteed the damping effect of box.

Compared with the traditional sound box, the sound box has the advantages that the vibration reduction effect of the box body can be effectively improved, so that better sound quality is presented, meanwhile, the sound box can be conveniently carried and transferred, and the convenience, the safety and the convenience in transportation of the sound box are guaranteed; thereby avoiding property damage.

Preferably, the anti-vibration wall further comprises vibration reduction units arranged in the annular cylindrical cavity, and the vibration reduction units are uniformly distributed in the annular cylindrical cavity; the structure can further consume the sound wave vibration transmitted into the anti-vibration wall, so that the vibration reduction effect of the box body is improved.

More preferably, the vibration reduction unit is a hollow elastic ball; when the sound wave vibration energy is transmitted to the vibration damping unit through the vibration resisting liquid, the vibration damping unit synchronously contracts and expands to consume the vibration energy; thereby achieving the effect of vibration reduction.

Preferably, the anti-vibration liquid is pure water; so as to reduce the production cost.

Preferably, the vibration-proof liquid is a fluid doped with metal powder; the structure can effectively improve the equivalent density of the anti-vibration wall and can ensure that the density of each part of the anti-vibration wall is uniform.

More preferably, the metal powder is copper powder; so as to effectively reduce the cost on the premise of ensuring the vibration reduction capability.
