Description

  The present invention relates to a portable terminal stand that also functions as a simple speaker.

A conventional portable terminal stand is described in Patent Document 1. This stand for mobile terminals is formed by folding a substantially rectangular and flat cardboard when unfolded, and the mobile terminal can be placed so that the angle of the mobile terminal can be adjusted while floating from the desk.
However, it does not have a function to amplify sound emitted from the mobile terminal, and there is a limit to the sound quality when listening to music or the like while the mobile terminal is standing.

JP-A-10-275986

  The problem to be solved is that the sound cannot be amplified when listening to music or the like with the mobile terminal standing, and the sound quality is limited.

In order to enable sound amplification and sound quality improvement with a simple structure, the present invention has an inner wall in a substantially horn-shaped outer cylinder, and an inner and outer space having a closed cross-section space between the inner wall and the outer cylinder. A double-wall structure, an insertion port provided in the outer cylinder for inserting a portable terminal, and an exposure port that exposes a speaker portion of the portable terminal provided on the inner wall side and inserted into the insertion port into the inner wall. It is characterized by comprising.

  Since the present invention is configured as described above, when the mobile terminal is inserted into the insertion port and supported, the speaker portion of the mobile terminal is exposed from the exposure port to the inner wall, and is discharged along the substantially horn-shaped outer cylinder from the inner wall. Thus, the sound of the mobile terminal can be amplified.

  Moreover, the overall rigidity can be improved by the internal and external double wall structure having the space portion of the closed cross section structure between the outer cylinder and the inner wall, and the sound quality can be easily improved.
