Abstract
The utility model discloses a sound box, which comprises a main box body. The main box body is provided with a release hole, on which a loudspeaker unit is fixed. A power supply and a sound box control circuit are arranged inside the main box body. A shock mount and a shock pad are disposed below the main box body. The shock pad is mounted on the shock mount and the main box body is arranged on the shock pad. The shock mount comprises a base for fixing the main box body and damping legs. Damping particles are arranged inside the base. Each damping leg is provided with an elastic component. In comparison with the prior art, as the sock mount and the shock pad are arranged, the damping particles are disposed inside the base of the shock mount and the damping legs are provided with the elastic components, the influence of the sound box vibration on timbre can be reduced, bass timbre is enhanced and overall balance of timbre is improved; and due to the arrangement of the shock pad composed of an aluminium-foil layer, glass fiber and a non-woven fabric layer, vibration interference of the sound box with the external world can be decreased, and a comfortable environment can be maintained.
Description
Technical field
The utility model relates to loudspeaker box device.
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 the sound equipment in the existing design, can produce vibrations and disturb during greater than critical value in the audio amplifier volume, influences tonequality on the one hand, and its bass tonequality and three-dimensional equilibrium degree all can't reach preferable degree, on the other hand, can produce vibrations and disturb other people.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model provides one and strengthens bass tonequality and improve the audio amplifier of whole machine balancing, and can reduce audio amplifier vibrations to external world and disturb.
For achieving the above object, technical scheme provided by the utility model is: a kind of audio amplifier, comprise main box, on described main box, be provided with sound releasing hole, on described sound releasing hole, be fixed with loudspeaker unit, in described main box, be provided with power supply and audio amplifier control circuit, at described main box to being provided with dynamic mount and beam, described beam is arranged on the dynamic mount, and described main box is arranged on the beam; Described dynamic mount includes pedestal and the shock reducing support leg that is used for fixing main box, is provided with the damping particle in described pedestal, is provided with elastic component on described shock reducing support leg; Described beam comprises aluminium foil layer, glass fibre and nonwoven layer, and described glass fibre is arranged between aluminium foil layer and the nonwoven layer, is provided with first adhesive-layer between described aluminium foil layer and the glass fibre, and described glass fibre and nonwoven layer are provided with second adhesive-layer.Compared with prior art, the beneficial effects of the utility model are, owing to be provided with dynamic mount and beam, and in the pedestal of dynamic mount, be provided with the damping particle, on shock reducing support leg, be provided with elastic component, can reduce the influence of audio amplifier vibrations tonequality, strengthen bass tonequality and the whole machine balancing that improves tonequality, owing to be provided with the beam that aluminium foil layer, glass fibre and nonwoven layer are formed, can reduce audio amplifier vibrations to external world and disturb, keep comfortable environment.
As specializing, described audio amplifier control circuit includes audio decoder chip, power amplifier chip, source of sound module, liquid crystal touch control module and key-press module, and described power amplifier chip, source of sound module, liquid crystal touch control module, key-press module and power supply are electrically connected with the audio decoder chip respectively.
