Detailed Description
The invention will be described in further detail with reference to the drawings and examples.
As shown in fig. 1 to 3, as an embodiment of the present invention, the present invention is applied to a tri-frequency division Hi-Fi speaker, which solves the problem that the existing tri-frequency division Hi-Fi speaker cannot be individually adjusted, and achieves individual hearing from structural optimization.
Specifically, the structure of the intermediate frequency regulator of the loudspeaker box in this example comprises a box body 1 and the intermediate frequency regulator arranged on the box body 1.
The front panel of the box body 1 is fixedly provided with 2 woofers 6, 1 tweeter 5 and 1 midrange 4 in parallel. The box is internally provided with a closed midrange cavity 7, the midrange loudspeaker 4 is arranged in the midrange cavity 7 in the box 1, an adjusting hole 3 is formed in a box rear panel corresponding to a front panel of the midrange loudspeaker 4 and arranged on the box 1, the intermediate frequency adjuster 2 is matched with the aperture of the adjusting hole 3, and the adjusting hole 3 can be sealed, so that the midrange cavity 7 is a sealed cavity. The intermediate frequency regulator 2 is opened, the intermediate frequency cavity 7 is communicated with the external atmosphere, the intermediate frequency audio is not limited by the fixed volume, the intermediate frequency loudspeaker system is similar to the low frequency loudspeaker phase guiding system, can bear higher power, and protects the performance of the intermediate frequency loudspeaker.
The middle-pitch loudspeaker works in a similar way to the bass loudspeaker cavity by opening the adjusting hole 3 on the box body 1 corresponding to the middle-pitch cavity of the middle-pitch regulator, so that the air in the cavity is compressed, and a replay effect is generated. The box body of the intermediate frequency regulator is provided with a hole for balancing air flow, and the adjusting hole 3 is opposite to the midrange loudspeaker for best effect through repeated experiments.
The intermediate frequency regulator 2 is made of black rubber material and is made of a die, the color of the intermediate frequency regulator is consistent with that of the back of a general loudspeaker box, and the intermediate frequency regulator is extremely high in concealment after being installed, so that rejection and appeal are not presented to users. The light-colored sound box adopts a light-colored intermediate frequency regulator, and the dark-colored sound box adopts a dark-colored intermediate frequency regulator.
On the sound box playing system, the intermediate frequency regulator is a very unique and important component of the three-frequency division Hi-Fi sound box. The intermediate frequency regulator can make the intermediate frequency of different music reach the field effect, and overcomes the unadjustable defect caused by the fixed brand and fixed style.
The example is unique and innovative in that:
in the prior art, a sponge ring and a sponge plug are added into a phase guide pipe matched with a woofer to inhibit the bass effect, the sponge is breathable, and certain airflow is in and out from the whole plug. The midrange regulator, while appearing similar in structure, is aimed at boosting the sound effect rather than suppressing it. The intermediate frequency regulator in this example can fine-tune the intermediate frequency response to achieve the desired auditory effect, and therefore, the effect is just opposite to that of a sponge plug added in low frequency.
As shown in fig. 4 to 6, preferably, the if adjuster 2 includes an adjuster body 201, the adjuster body 201 is provided with a hollow portion, and the if adjuster 201 further includes a rubber stopper 202 sealing the hollow portion.
The regulator body 201 is T-shaped, and includes a limiting head 2011 and a middle post 2012 connected to the limiting head 2011, where a step part limiting the insertion position of the rubber plug is provided in the middle of the limiting head 2011.
To ensure stability of installation, a turn of back-off 20121 is provided at the end of the center pillar 2012, and the intermediate frequency regulator is easily installed without loosening. The outer wall of the middle column 2012 is provided with a limiting protrusion 2013. The side wall of the hollow part is provided with a plurality of annular protrusions 2014 in interference fit with the rubber plug 202, so that the tightness of the midrange cavity 7 is ensured.
Spacing protruding 2013 with annular protruding 2014 is in the middle column inner and outer wall interval distribution, when the inner and outer wall atress of middle column 2012 respectively with box 1 and rubber stopper 202 interference fit, elastic deformation atress is more even, easy to assemble and dismantlement.
In order to avoid the loss of the intermediate frequency regulator 2 after being pulled out, the case may further be provided with a storage structure for fixing the intermediate frequency regulator 2, for example, a groove with a size adapted to the intermediate frequency regulator 2 and the rubber stopper 202, or a clip strip.
In the embodiment, hundreds of tests prove that the size of the intermediate frequency regulator is related to the volume of the intermediate frequency cavity,
when the volume of the midrange cavity is smaller than 4 liters, the diameter of the midrange column is adopted
Intermediate frequency regulator and diameter ∈>
A rubber stopper;
when the volume of the midrange cavity is between 4 liters and 10 liters, the diameter of the midrange column is adopted
Intermediate frequency regulator and diameter of (2)
A rubber stopper;
when the volume of the midrange cavity is 10-15 liters, the diameter of the midrange column is adopted
Intermediate frequency regulator and diameter ∈>
A rubber stopper.
This case adopts T type rubber regulator body and rubber buffer 202 to constitute intermediate frequency regulator system, and the intermediate frequency chamber 7 at its T type rubber regulator body and audio amplifier back are together fixed, have sealed intermediate frequency chamber and external passageway after the stopper is inserted into rubber buffer 202, and unanimous with fixed intermediate frequency chamber, through rubber buffer 202 and regulator body 201, can have two-stage regulation result.
As shown in fig. 7 and 8, the rubber plug is removed to obtain a primary adjusting effect, and the whole intermediate frequency regulator is removed to obtain a secondary adjusting effect. It can be seen that the rubber plug 202 is easily pulled out in this example, so that the midrange closed cavity is connected with the external atmosphere; after the sensitivity of the middle frequency band is easily improved, the rubber middle frequency regulator is pulled out again, so that the air guide channel of the middle frequency cavity is enlarged, the sensitivity of the middle frequency band is improved again, the front and back distances of a listener are shortened by music, overtones of the musical instrument are obvious and prominent, and the effect of field sense is achieved. The middle voice cavity is connected with the atmosphere, and the middle voice loudspeaker in the sound box system can bear the characteristic of larger music power. According to the invention, through the arrangement of the intermediate frequency regulator body and the rubber plug, the secondary regulation effect is realized, the sensitivity is improved by 0.5dB to 1.5Db from 300Hz to 2000Hz, the music playing achieves the field effect, and the bearing power of the midrange horn is improved; can meet the music enjoyment of different music lovers.
The sound box with the structure of the invention is in good favor of global associates and agents in the sound box of British Density, munich in Germany, beijing in China, shanghai, guangdong, hong Kong, taiwan and the like.
