Abstract
A docking station for sound amplification and sound quality enhancement is provided. The docking station includes a support structure for holding a mobile terminal having an internal speaker to sustain the posture of the mobile terminal, and a body for supporting the support structure, and for physically contacting the speaker to increase the volume of sound output from the speaker. The body includes a collecting hole for contacting the speaker to collect sound waves, and a guide hole that extends from the collecting hole through the body to the outside along an extension direction, is divided into two branches within the body to guide the collected sound waves along different paths, and has a horn shape whose cross section increases along the extension direction. Hence, the docking station can increase the volume of audible sound and sound quality without separate supply of power.
