Sound guide for speaker and handset for mobile communication using the same
First Claim
1. A mobile communication terminal handset, comprising:
- a rigid single body case having a sound propagation hole on a front side forming an opening on the case;
means for providing wireless communication, said means being provided within the rigid single body case;
a speaker coupled to the case to generate audible sounds;
a sound chamber between the speaker and the sound propagation hole, wherein the speaker is positioned at a first prescribed angle other than 0° and
180°
with respect to the front side of the case, wherein a first side of the sound chamber is formed along a portion of the first side of the case that contains the sound propagation hole, and a second side of the sound chamber is aligned with the speaker, and wherein the sound propagation hole allows audible sounds from the speaker to pass directly from the sound chamber to outside of the case; and
a sound guide to guide audible sounds by directing a propagation direction of the audible sound at a second prescribed angle.

Abstract
A sound guide for a speaker is capable of guiding a sound of a desired volume to a desired position regardless of installation structure of the speaker. The sound guide for a speaker includes a speaker support for supporting the speaker in a case, and a sound guide groove formed in an inner side of the speaker support, for guiding the direction of the audible signal of the speaker at a predetermined angle. The sound propagation groove has one side coupled with the speaker and other side coupled with a sound propagation hole which is formed in the case. A handset for mobile communication using the sound guide includes a case having a speaker therein, and a sound propagation hole for propagating the audible signal generated by the speaker to outside, wherein the speaker is slanted at a predetermined angle with respect to a front side of the case. Preferably, the sound guide is mounted in an upper side of the speaker to guide the audible signal to the sound propagation hole by directing the audible signal at a predetermined angle.
