## Abstract

Provided in the present invention is a stereo sound box, including: a box body. Two sets of sound generating units are provided on a surface of the box body, correspondingly for a left sound channel and a right sound channel. Each set of sound generating units includes a low sound unit and at least one high sound unit. The low sound units of the two sets of sound generating units are arranged to mirror each other so as to neutralize the inertia of vibrations. The high sound units are arranged outside each low sound unit. In the described stereo sound box, high-fidelity low sound can be maintained even while the box body is kept light.

## Claims

### Claim 1

A stereo sound box, comprising:
a blow molded, spherical box body,
two sets of sound generating units provided on a surface of the blow molded, spherical box body, correspondingly for a left sound channel and a right sound channel; each set of sound generating units comprises a low sound unit and at least one high sound unit; and
the low sound units of the two sets of sound generating units are arranged to mirror each other thereby neutralizing inertia of vibrations; and the high sound units are arranged outside each low sound unit.

### Claim 2 (depends on 1)

The stereo sound box of claim 1, wherein four high sound units are arranged outside each low sound unit; and the high sound units are arranged on an upper side, a lower side, a left side, and a right side of the low sound unit.

### Claim 3 (depends on 2)

The stereo sound box of claim 2, further comprising an inverted tube, wherein an open end of the inverted tube communicates with the surface of the blow molded, spherical box body, and faces a user.

### Claim 4 (depends on 1)

The stereo sound box of claim 1, further comprising an inverted tube, wherein an open end of the inverted tube communicates with the surface of the blow molded, spherical box body, and faces a user.

### Claim 5 (depends on 4)

The stereo sound box of claim 4, wherein the inverted tube extends in a non-perpendicular angled direction from the surface of the box body.

### Claim 6 (depends on 1)

The stereo sound box of claim 1, wherein the blow molded, spherical box body is an integrally formed pressure container.

### Claim 7 (depends on 1)

The stereo sound box of claim 1, wherein magnets of the two low sound units are connected to each other through a connecting member, and when the two low sound units have a movement trend of approaching or moving away from each other, the connecting member provides a limiting force against a relative movement direction for the low sound units.
