The substrate 1 can also be provided with a corresponding opening for the camera, the flash lamp or the button of the body E. It is understood by those skilled in the art that the substrate 1 should not be subjected to the structure disclosed in the drawings of the present invention. The form is limited.

The ring wall portion 2 is disposed on the periphery of the substrate 1 and is mainly used for combining with the body E. The ring wall portion 2 can be combined with the substrate 1 by any combination, or with the substrate 1 The invention is manufactured in one piece, and the invention is not limited. A plurality of auxiliary positioning portions 21 may be disposed at the free end of the ring wall portion 2, so that the ring wall portion 2 can be wrapped around the side edge of the body E, and the plurality of auxiliary positioning portions 21 are locked to the machine.

When the backplane of the fuselage E is abutted, a good airtightness can be formed, so that the amplitude of the acoustic effect of the handheld electronic device and the sheath thereof of the present invention is more remarkable.

Referring to Figures 4 and 5, which are a second preferred embodiment of the present invention, the embodiment is substantially identical to the first preferred embodiment described above, and the difference is mainly in that at least one barrier member of the sheath The 3 series includes two barrier members, and the two barrier members 3 are disposed between the first side wall 2a and the second side wall 2b. Thereby, the two barrier members 3, the first side wall 2a and the second side wall 2b will collectively form an air chamber R, as shown in FIG. 6, when the body E is placed When entering the accommodating space S, the backboard of the fuselage E abuts the two barriers 3 respectively, so that the air chamber R is closed by the backboard of the fuselage E, and the bell mouth E1 is The air chambers R are aligned with each other and the air chamber R will serve as a resonant space. According to this, the at least one barrier The number of pieces 3 may be one or several, and the invention is not limited thereto. It is noted that one of the barrier members 3 can open through an opening 31 of the air chamber R, and when the air chamber R is used as a resonance space, sound waves can pass through the opening 31 and the through hole of the ring portion 2 The outer portion of the second barrier member 3 can be respectively disposed with a pad body 32 to ensure that the two barrier members 3 abut against the back plate of the body E, respectively.

However, the barrier member 3 having the opening 31 may also extend in different directions. For example, among the two adjacent barrier members 3, one of the barrier members 3 is disposed perpendicular to the first sidewall spacer 2a, and The other barrier member 3 is disposed parallel to the first side wall 2a, so that the air chamber R forms a 90 degree turn at the boundary of the two barrier members 3, and the air R can still form a continuous bending curve.
