Problems solved by technology

However, in the case of the existing zeolite getter, it must be manufactured in a small size to obtain the volume expansion effect. However, the zeolite getter is difficult to handle because it is easily blown away by the wind, etc., and it is difficult for the sound resonance space. It is also very difficult to perform quantitative injection, so there is a disadvantage that expensive quantitative injection equipment is required
In addition, zeolite getters have the following problems due to their weak mechanical strength, that is, they are easily broken by external force or the surface is damaged, resulting in performance degradation, and the flow of air is blocked by fine particles that fall off when broken, resulting in a decrease in acoustic characteristics, etc.

Embodiment 1

[0111] Step 1: Prepare a phenol-based (Phenol-Based) activated carbon fiber (fiber) with a diameter of approximately 0.013 mm.

[0112] Step 2: Weave the above-mentioned Phenol-Based activated carbon fiber (fiber) into a fabric sheet form by using a fabric loom.

[0113] Step 3: The getter in the form of a fabric sheet is cut with a cutting device to have a volume of approximately 80% of the sound resonance space of the micro-speaker box system.

[0114] Step 4: Inject the one-piece Phenol-Based activated carbon getter formed by the above cutting into the sound resonance space of the micro-speaker box system.

experiment example 1

[0121] In order to confirm the effect of improving the bass characteristic by the volume expansion effect of the speaker box system getter according to the embodiment of the present invention, the following experiments were conducted.

[0122] For the speaker box systems of the above-mentioned Example 1, Comparative Example 1, and Comparative Example 2, impedance values ​​according to frequencies were measured with an impedance meter (Impedance Meter), and the results are shown in Figure 14 , and the sound pressure (sound pressure, SPL) value according to the frequency was measured with a decibel meter (sound meter) and the results are shown in Figure 15 .

[0123] Such as Figure 14 As shown, the resonance points of the speaker box systems of Example 1, Comparative Example 1, and Comparative Example 2 were 8.55 ohm at 919 Hz, 8.48 ohm at 949 Hz, and 9.86 ohm at 1008 Hz.

[0124] It can be seen that the resonance point of Example 1 is shifted to the low frequency band by a...

Abstract

The present invention relates to a fabric sheet-shaped getter for a speaker box system, a method for manufacturing the same, and a speaker box system comprising the getter, the getter for a speaker box system being characterized in that the getter is in the shape of a fabric sheet comprising a plurality of woven fibers, and the fibers comprise a porous carbon-based substance.

Description

technical field [0001] The present invention relates to a speaker box system getter in the shape of a fabric sheet and a manufacturing method thereof, as well as a speaker box system comprising the getter (Air absorber of speaker-box system in fabric sheet form and preparation method thereof, speaker-box system comprising the same). Background technique [0002] Recently, a micro speaker box system used in a smartphone is equipped with a sound resonance box that functions as a sound resonance space in a certain part of the speaker box module with a built-in magnetic core speaker in order to achieve rich bass reproduction in a compact and small size. In particular, in a small-sized microspeaker, the sound resonance space plays an important role in the acoustic characteristics of the low-frequency region, and the larger the resonance space, the more favorable the reproduction of the low-frequency region, and the reproduction bandwidth can be widened. [0003] However, in view...
