no. 1 Embodiment approach
[0102] A speaker device according to a first embodiment of the present invention will be described with reference to FIG. 1 . FIG. 1 is a cross-sectional view showing the structure of an example of the speaker device according to the first embodiment. In FIG. 1 , the speaker device includes a box 10 , a speaker unit 11 , a gas adsorbent 12 , and a shielding member 13 . In addition, the speaker device shown in FIG. 1 is a sealed type speaker device.
[0103] The speaker unit 11 is, for example, an electrodynamic speaker. The speaker unit 11 is installed in an opening portion formed in the front upper portion of the box body 10 . The gas adsorbent 12 is, for example, powdery activated carbon (hereinafter referred to as powdered activated carbon) having an average particle diameter of 0.01 to 0.03 mm. In addition, the above-mentioned powdery activated carbon is obtained by pulverizing activated carbon produced from, for example, coconut husks as a plant material to an average ...
no. 2 Embodiment approach
[0121] A speaker device according to a second embodiment of the present invention will be described with reference to FIG. 4 . Fig. 4 is a cross-sectional view showing the structure of an example of the speaker device according to the second embodiment. The speaker device of the present embodiment differs from the speaker device of the first embodiment in that it is a speaker device of a so-called phase inversion method including a passive radiator 21 . Hereinafter, the difference will be mainly explained.
[0122] In FIG. 4 , the speaker device includes a box 20 , a speaker unit 11 , a gas adsorber 12 , a shielding member 13 , a passive radiator 21 , and a partition 22 . In addition, the speaker unit 11, the gas adsorption body 12, and the shielding member 13 shown in FIG. 4 are the same as those of the said 1st Embodiment, and are assigned the same code|symbol, and description is abbreviate|omitted.
[0123] The speaker unit 11 is installed in an opening portion formed in ...
no. 3 Embodiment approach
[0132] A speaker device according to a third embodiment of the present invention will be described with reference to FIG. 7 . 7 is a diagram showing a side cross-sectional view of an example of a speaker device according to a third embodiment and a rear view partially showing a cross-section. The speaker device of the present embodiment differs from the speaker device of the first embodiment in that it is a speaker device of a so-called phase inversion method including an audio port 31 . In addition, the speaker device according to the present embodiment differs from the speaker device according to the first embodiment in that it further includes a dividing arrangement mechanism 32 to divide and arrange the gas adsorbent 12 . Hereinafter, the difference will be mainly explained.
[0133] In FIG. 7 , the speaker device includes a box 30 , a speaker unit 11 , a gas adsorber 12 a , a shielding member 13 , an acoustic port 31 , and a division arrangement mechanism 32 . In additi...
