Embodiment Construction
[0014] The accompanying drawings also disclose specific implementations of the present invention, which illustrate the technical solutions, working principles and specific implementations of the present invention in graphic form.
[0015] The accompanying drawings also disclose an embodiment of the invention.
[0016] The accompanying drawings show that the bottom of the cup (4) is the area for sound generation and pickup, and the mouth of the cup (1) is the sound radiation port and the sound receiving port; the side wall of the water cup has a narrow side wall (2) and a wide side wall in an arc shape (3) Composition, the arc surface is convex, and can be an arc surface or a non-arc surface. Such an arc surface has high rigidity and is not easy to deform or vibrate. From the bottom of the cup (4) to the mouth of the cup (1), the width of its narrow side wall (2) and the width of the wide side wall (3) gradually increase, and the width of the narrow side wall (2) and the wide s...
