Labyrinth type thin super bass loudspeaker sound tube structure

Technical Field

The utility model relates to a super bass speaker technical field is a thin super bass speaker sound tube structure of labyrinth particularly.

Background

The loudspeaker is a transducer for converting electric signal into sound signal, its performance has great influence on sound quality, and it is the weakest device in sound equipment, and for sound effect it is the most important one, and the audio electric energy of loudspeaker makes its cone or diaphragm vibrate and resonate (resonate) in the surrounding air by means of electromagnetic, piezoelectric or electrostatic effect to make sound.

In the prior art, a subwoofer generally requires a large box space to couple with unit vibration to generate shocking low-frequency effect, but is often limited by space, so that application scenes are greatly reduced, and a plurality of problems such as inconvenience in carrying and the like are brought on the basis of space satisfaction; if the required space is reduced, the sound quality is also reduced, and the effect of using the speaker is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the not enough of prior art, provide a less, the higher speaker sound tube structure of tone quality in required space.

In order to achieve the purpose, the labyrinth type thin subwoofer sound tube structure comprises three cavities which are communicated with each other, wherein a five-time longitudinal folding reflection structure is arranged in a first cavity, and the tail end of the five-time longitudinal folding reflection structure of the first cavity is communicated with a second cavity through a 90-degree guide return structure; the second cavity is internally provided with a six-time longitudinal folding reflection structure, the tail end of the six-time longitudinal folding reflection structure of the second cavity is connected with a two-time short-distance transverse folding reflection structure through 90-degree guiding, and the tail end of the two-time short-distance transverse folding reflection structure is communicated with the third cavity; and a triple long-distance transverse folding reflection structure is arranged in the third cavity.

Preferably: the tail end of the third cavity is communicated with the loudspeaker, and the third cavity finally presses air generated by vibration and compression of the loudspeaker out of the loudspeaker from the bottom space of the loudspeaker.

Preferably, the following components: all parts of the loudspeaker are provided with sealing treatment, and air compressed by sound vibration of the loudspeaker unit is transmitted to the output through the labyrinth sound tube.

Compared with the prior art, the utility model, its advantage lies in:

1. the volume of the inner cavity space of the super bass loudspeaker is effectively compressed;

2. and the designed low-frequency lower limit frequency and energy are improved.

Drawings

Fig. 1 is a structural view of the sound tube of the present invention;

fig. 2 is a front view of the present invention;

in the figure: 1. the wood box comprises a first cavity, 2, a second cavity, 3, a third cavity and 4, a wood box.

Detailed Description

Referring to fig. 1, a sound tube junction of a labyrinth subwoofer, wherein a box body is made of an MDF high-density board, and specifically includes a first cavity, a second cavity and a third cavity, the three cavities are communicated with each other, sound waves enter the first cavity, and are reflected inside the first cavity through five times of longitudinal folding, the process is completed in a five times of longitudinal folding and reflecting structures, and the five times of longitudinal folding and reflecting structures have a unique path, and are guided to return to the second cavity by 90 degrees after the completion; after the second cavity is longitudinally folded and reflected for six times, the process is finished in a six-time longitudinally folded and reflected structure, and after the process is finished, 90-degree guiding connection is carried out for 2 times of short-distance transverse folding and reflection, and the second cavity enters a third cavity; the third cavity is transversely folded and reflected through the cubic long distance, the process is completed in the cubic long distance transversely folded and reflected structure, the tail end of the third cavity is communicated with the loudspeaker, and finally air compressed by loudspeaker vibration is pressed out of the loudspeaker from the bottom space of the loudspeaker.

All parts of the loudspeaker are well sealed, and air compressed by sound vibration of the loudspeaker unit is transmitted to the output end only through the labyrinth type sound tube. The five-time longitudinal folding reflection structure, the six-time longitudinal folding reflection structure and the three-time long-distance transverse folding reflection structure are all provided with unique passages, each reflection is a straight line, and sound waves can smoothly pass through the structures from the circular arc structure to the next reflection.

Taking a 6.5 inch bass unit as an example, the diameter of the unit caliber is about 16.5cm, the space occupied by the first cavity, the second cavity and the third cavity is about one unit caliber, the total thickness of the whole wooden box can be controlled to be about 25cm, the total length is about 75cm, and the total width is about 50cm.

Through the sound pipe structural design of labyrinth, can effectively compress the inner chamber space volume of super bass speaker, even if use the loudspeaker unit of small diameter (like 8 cun bass unit, even 6.5 cun bass units), still can obtain abundant low frequency dive effect. The labyrinth type loudspeaker is coupled with surrounding media by manufacturing a set of folding reflection pipelines with rectangular sections behind the horn unit, so that the designed low-frequency lower limit frequency and energy can be improved even if the horn unit with a small caliber and a small box body space are used. When the phase of the radiated sound wave is consistent with that of the sound wave in front of the loudspeaker unit, the sound playing pipeline of the labyrinth type sound box plays a role of lifting, which is a main starting point of the labyrinth type sound box, if the length of the sound tube is 1/2 wavelength of the radiation sound frequency, the phase can move to be equal to 180 degrees, and at the moment, the sound wave released from the tail end opening of the sound playing pipeline of the labyrinth type sound box and the sound emitted in front of the loudspeaker unit are in the same phase.

The above, only for the concrete implementation of this utility model, but the scope of protection of this utility model is not limited to this, and any person skilled in this technical field is in the technical scope of this utility model discloses, according to the technical scheme of this utility model and novel design add in equal replacement or change, all should be covered in the scope of protection of this utility model.
