A sound control apparatus capable of improving the quality of the reproduction sound output from an electronic apparatus includes a sound control mat, and a support unit for supporting an electronic device having a speaker on the sound control mat. The sound control mat has a sound controlling structure configured to control the resonance of sound output from the speaker of the electronic apparatus when it is supported by the sound control mat. With this sound control apparatus, it is possible to enjoy a good tone directly output from a television, a stereo system or any other device having a small speaker without needing a special devising.

1. A sound control apparatus comprising: a sound control mat;a frame configured to cover a side surface of the sound control mat;a support unit configured to support an electronic apparatus having a speaker on the sound control mat; anda frame configured to cover a side surface of the sound control mat,wherein the sound control mat has a sound controlling structure configured to control the resonance of sound output from the speaker of such electronic apparatus when such apparatus is supported by the sound control mat, andwherein the frame is provided with a bottom portion having substantially the same area as the sound control mat, and a spacer located on the bottom surface of the frame that forms a space between the sound control mat and the bottom surface of the frame. 2. The sound control apparatus of claim 1, wherein the support unit comprises a sponge layer which is formed on the surface of the sound control mat with an indent section having a smaller size than the electronic apparatus to be supported on the mat such that such electronic apparatus can be inserted in and supported by the indent section. 3. The sound control apparatus of claim 1, wherein the electronic apparatus is a wristwatch type terminal, a camera, a small size video recorder, a radio receiver, a digital music player, an IC recorder, or a projector. 4. The sound control apparatus of claim 1, wherein the sound control mat comprises at least one of needle felt, bestray, softray, glass wool, thermo wool, phenol resin, polyurethane, fibrous mineral wool, glass fiber and open-cell foam. 5. The sound control apparatus of claim 1, wherein the sound control mat comprises a plurality of sound absorbing sheets joined together with an adhesive in the form of a laminate. 6. The sound control apparatus of claim 5, wherein the adhesive comprises a viscous adhesive which does not solidify after formation of the laminate, maintains its viscosity when a mobile terminal booth is used, and functions as the sound controlling structure. 7. The sound control apparatus of claim 5, wherein the laminate comprises a resin sheet interposed between each adjacent ones of the sound absorbing sheets. 8. The sound control apparatus of claim 7, wherein the resin sheet has a thickness of 0.1 mm to 0.5 mm. 9. The sound control apparatus of claim 7, wherein the resin sheet is provided with a plurality of openings, and wherein the sound absorbing sheets are directly adhered to each other by the adhesive through the openings, and indirectly adhered to each other by the adhesive through the resin sheet. 10. The sound control apparatus of claim 1, further comprising a spacing member configured to provide a space between the sound control mat and an electronic apparatus, when such electronic apparatus is supported by the sound control mat. 11. The sound control apparatus of claim 10, wherein a plurality of suction pads comprise the spacing member on a surface of the sound control mat. 12. The sound control apparatus of claim 1, wherein the sound control mat is shaped in a cylindrical form, wherein the spacing member is provided as a number of rods which are projected upward from a surface of the sound control mat, and wherein the rods are longest at a center of the sound control mat and gradually become shorter toward an outer circumference of the sound control mat. 13. The sound control apparatus of claim 10, wherein the sound control mat and such electronic apparatus are spaced by a distance of 3 mm to 7 mm when such electronic apparatus is supported by the sound control mat. 14. The sound control apparatus of claim 3, further comprising said sound absorbing mat comprising a plurality of sound absorbing sheets joined together with an adhesive in the form of a laminate, and a frame configured to cover the side surface of the laminate. 15. The sound control apparatus of claim 4, wherein the frame is configured to cover only the side surface of the laminate of the sound absorbing sheets, and front and back surfaces of the laminate are open to air.
