Description

Ultra-low sound box with novel structure for professional stage

Technical Field

The utility model relates to the technical field of ultra-low sound boxes, in particular to an ultra-low sound box with a novel structure for a professional stage.

Background

In the professional stage sound box industry, especially in the field of stage ultra-low sound, common ultra-low sound box structures comprise a full labyrinth type, a half labyrinth type, a direct injection type, a closed type, a phase guide type and the like, and the old homogenization homogeneous structure in the prior art is too many, so that the old homogenization homogeneous structure is not innovated, and the appearance and tone effect which is not forgotten by people is not provided. The pursuit of the young consumers for good music, the satisfaction of spirit, the fictitious temperament and the like cannot be met.

Furthermore, as a plurality of similar products exist in the market, the structure tone is different, and the plate, the material, the box body structure and the inverter tube structure design which have decisive effect on the ultra-low sound, the required box body volume calculation and the unit have no standard production and control. The structural design is unreasonable, and the units are not reasonably configured. And the appearance is outdated, the sound is abused, the aesthetic feeling is tired, and the innovative design concept is not provided, so that the humming sound, wind noise, dyeing sound and the like of the ultra-low sound box can not be effectively controlled, and the requirement of people on sound can not be effectively solved.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model aims to provide an ultra-low sound box with a novel structure for a professional stage, which realizes the integrated design of cutting and punching through an integrated mechanism and enables consumers to use the ultra-low sound box more easily.

In order to achieve the purpose, the utility model adopts the following technical scheme:

an ultra-low sound box with a novel structure for a professional stage comprises a sound box shell, wherein an upper resonance cavity and a lower resonance cavity are oppositely arranged in the sound box shell, a middle cavity is formed by enclosing the upper resonance cavity and the lower resonance cavity, and the upper resonance cavity and the lower resonance cavity are respectively provided with a first phase inversion pipe outlet and a second phase inversion pipe outlet; the middle part intracavity is equipped with first loudspeaker unit and second loudspeaker unit, wherein, the cone vibration face of first loudspeaker unit set up in first paraphase pipe export, the cone vibration face of second loudspeaker unit set up in second paraphase pipe export.

It should be noted that, a first air flow channel communicated with the outlet of the first phase inversion tube is arranged in the upper resonant cavity; and a second airflow channel communicated with the outlet of the second phase inversion pipe is arranged in the lower resonance cavity.

It should be noted that the size of the enclosure is 600 × 1100 × 780 MM.

It should be noted that the size of the middle cavity is 230 × 1064 × 520 MM.

It should be noted that, sound-absorbing fireproof cotton is arranged at each inner edge angle of the sound box shell.

It should be noted that one side of the middle cavity is provided with an iron net, and the inner surface of the iron net is covered with a waterproof, dustproof and breathable net cotton.

The utility model has the advantages that the factors that ultra-low sound has influence on temperature and humidity in air transmission can be well avoided through the structural acoustics of the inverter tube, so that the superposition of low-frequency lower-limit energy is realized in different use environments. Furthermore, the sound box can make the sound of the sound box mellow, full and clean, has strong surrounding sense, strong diving depth and strong sense of strength, has strong sound pressure level and higher sensitivity, and is more stable and durable.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.

As shown in fig. 1 and 2, the present invention is an ultra-low sound box with a novel structure for professional stage, including a sound box housing 1, wherein an upper resonance cavity 2 and a lower resonance cavity 3 are oppositely arranged in the sound box housing 1, a middle cavity 4 is formed by enclosing the upper resonance cavity 2 and the lower resonance cavity 3, and the upper resonance cavity 2 and the lower resonance cavity 3 are respectively provided with a first inverter tube outlet 5 and a second inverter tube outlet 6; be equipped with first loudspeaker unit 7 and second loudspeaker unit 8 in the middle part cavity 4, wherein, the cone vibration face of first loudspeaker unit 7 set up in first phase inversion pipe export 5, the cone vibration face of second loudspeaker unit 8 set up in second phase inversion pipe export 6.

Furthermore, a first air flow channel communicated with the outlet of the first phase inverter tube is arranged in the upper resonance cavity; and a second airflow channel communicated with the outlet of the second phase inversion pipe is arranged in the lower resonance cavity.

Further, the size of the sound box shell is 600 × 1100 × 780 MM.

Further, the size of the middle cavity of the present invention is 230 × 1064 × 520 MM.

Furthermore, sound-absorbing fireproof cotton is arranged at each inner edge angle of the sound box shell.

Furthermore, an iron net is arranged on one side of the middle cavity, and waterproof, dustproof and breathable net cotton is covered on the inner surface of the iron net.

Examples

The two horn units of the utility model do vibrating air movement in a common box body under the action of power amplifier signal current, send out audio signals through the air movement, generate audio airflow, and then are respectively provided with two inverter tube airflow channels with the same size in the resonant cavity. Specifically, the low-frequency signal emitted by the inverter tube is superposed with the same low-frequency signal in front, so that the sound signal can be better played. Under the structural design, internal resonant air flows are better distributed respectively, and the magnetic steel resonant frequency at the rear parts of the two loudspeaker units is added, so that the aim of superposing the same frequency on the front surface of the sound box together is fulfilled. Furthermore, because all parts in the sound box shell are strengthened to prevent vibration, and the sound-absorbing fireproof cotton for preventing column wave processing is added at each corner, the sound produced by the sound box is clean, mellow, full, strong in surrounding sense and deep in diving.

Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
