Abstract
The utility model relates to a small ball-shaped ceramic sound box belonging to the field of a loudspeaker. The utility model is composed of a ball-shaped casing, a loudspeaker and bolts, wherein, a bolt fixing hole and a connection hole are arranged on the casing, a circular hole is arranged on the casing, the loudspeaker is arranged on the circular hole, an electrode of the loudspeaker is provided with a fixing hole, and the loudspeaker is fixed by bolts through the fixing hole on the casing. The structural design of the utility model is simple, the utility model can be used as a middle pitch satellite sound box and a high pitch satellite sound box in a satellite/low pitch type domestic cinema and a sound system, the utility model can be conveniently fixed on a wall, a ceiling and a special table frame, and the utility model has a decorative effect.
Description
The small-sized spherical ceramic loudspeaker box of the utility model belongs to the loud speaker field, particularly relates to a kind of audio amplifier.
Existing audio amplifier adopts square maximum, because the profile corner angle produce acoustic wave diffraction, the inner chamber plane produces standing wave, the tonequality of audio amplifier is affected, for preventing the casing harmonic wave, audio amplifier requires rigidity preferably, and small-sized audio amplifier is had bigger difficulty on processing and structural design.
The purpose of this utility model is to avoid weak point of the prior art, adopts simple structure, provides a kind of volume little, and rigidity is big, and the small-sized spherical ceramic loudspeaker box that tonequality is good has been avoided the shortcoming of ceramic frangible and processing difficulties.
The purpose of this utility model reaches by following measure, it is the good rigidly that utilizes pottery, solid characteristics are avoided the shortcoming of the frangible and processing difficulties of pottery, adopt the simple structure of circular arc, requirement in conjunction with audio amplifier realizes the purpose of this utility model, it is by spherical shell, loudspeaker, and bolt is formed, bolt hole and line hole are arranged on housing, circular hole is arranged on housing, and loudspeaker are arranged on the circular hole, on the pole of loudspeaker fixing hole are arranged, by bolt by the fixing loudspeaker of the fixing hole on the housing, since the good rigidly of pottery, solid characteristics, and the volume of audio amplifier can be less, adopt the simple structure of insert, make the ante-chamber effect reduce to minimum; Profile does not have corner angle, avoids producing the influence of acoustic wave diffraction to Frequency Response, and the inner chamber circular arc does not have the plane, does not have the generation standing wave, makes the tonequality of small-sized audio amplifier better.
Spherical shell of the present utility model can adopt two hemispheres to fasten, and fixes two hemisphere and loudspeaker by bolt by the fixing hole on spherical shell.
Because sphere has acoustic characteristic preferably, become a spheroid after adopting two hemispheres fastenings, or spherical overall structure can be given full play to characteristics of the present utility model.
The utility model structural design is simple, be skillfully constructed, the characteristics of pottery and audio amplifier have been given full play to, can be used for the middle and high sound satellite audio amplifier in satellite/bass formula home theater and the sound system, small and exquisite ceramic spherical shape, can be fixed on easily on wall, ceiling and the special-purpose stand, have the effect of ornament.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in drawings, the utility model is by spherical shell 1, loudspeaker 2, bolt 3 is formed, bolt hole and line hole are arranged on housing, circular hole is arranged on housing, loudspeaker are installed on the circular hole, on the pole of loudspeaker fixing hole are arranged, by bolt by the fixing loudspeaker of the fixing hole on the housing, loudspeaker are installed on the circular hole, adopt a bolt loudspeaker can be fixed, there is the sphere spill at the fixing hole place on housing, and the place is provided with sphere cushion block 4 in the sphere spill, the deviation that produces when adapting to the assembling of housing and loudspeaker is avoided the damage pottery.Circular arc outer cover 5 is installed on loudspeaker, and the audio amplifier outer surface becomes a spheroid.
