Description
Technical Field
The utility model relates to a music equipment, especially a sound box.
Background
The design of the sound box is varied, the theory is wide in design, and the presented effect is also five-flower eight-door; but in general, loudspeaker designs mainly address the bass presentation problem. The high pitch and the middle pitch are directly presented by the loudspeaker. In reality, a certain middle tone is required to be presented by the middle-bass loudspeaker, so that the problem of perfect presentation of the low tone and the middle tone needs to be solved by the loudspeaker box. Then, the sound box is designed to pay attention to the seamless connection of the middle bass while the box body is enabled to emit bass; and the influence of standing wave effects such as refraction, diffraction and scattering of bass and mediant in the box body. Otherwise, the midrange, bass presentation will be distorted (the cabinet will be cluttered), the midrange bass will be disjoint, there will always be little sound, etc. The sound box on the market is mainly designed in the aspects of box volume, sound guide hole position, size and length, box length-width-height ratio, wave-absorbing material addition and the like. Some high-grade sound boxes pay attention to the installation position of the woofer, but the other aspects are deficient.
The design of the sound box can be compatible without paying attention to volume, a guide hole (front opening) is formed in the same direction of a loudspeaker, and wave-absorbing materials and the like are not required to be added to obtain the design cloth which perfectly presents middle and low tones. The answer is affirmative. We have invented such a type of enclosure in combination with other enclosure designs in enclosure design practice.
