Claims

1. A siren beverage cup comprising a cup body, characterised in that: A sound-generating diaphragm base (1) extends downward from the bottom of the cup body. The bottom of the sound-generating diaphragm base (1) is covered with a vibrating sound-generating diaphragm (2). A resonant cavity (3) independent of the inner cavity of the cup body is formed between the sound-generating diaphragm (2) and the bottom of the cup body. A sound-generating diaphragm protective cover (4) is provided on the sound-generating diaphragm base (1) to protect the sound-generating diaphragm from external damage. An insertion hole (5) penetrating the resonant cavity (3) is provided on the sound-generating diaphragm base (1) and the sound-generating diaphragm protective cover (4) or the sound-generating diaphragm base (1). An air blowing tube is detachably inserted into the insertion hole (5) to drive the sound-generating diaphragm (2) to vibrate and generate sound by blowing air.

2. A siren beverage cup according to claim 1, characterized in that: The cup body includes an inner cup body (8) and an outer cup body (9), which are detachably connected; the sound-emitting diaphragm base (1) includes a first annular protrusion (10) disposed at the bottom of the outer cup body (9) and a second annular protrusion (11) fitted outside the first annular protrusion (10); the lower end of the first annular protrusion (10) extends beyond the second annular protrusion (11), and the first annular protrusion (10) communicates with the inner cavity of the outer cup body (9); the sound-emitting diaphragm is fixed on the bottom surface of the first annular protrusion (10) and the second annular protrusion (11), and the resonant cavity (3) is located between the bottom of the inner cup body (8) and the sound-emitting diaphragm (2).

3. A siren beverage cup according to claim 2, characterized in that: The bottom of the inner cup (8) is provided with a tuning rack and a tuning disc (12). The tuning rack has two or more tuning slots (13). The tuning disc (12) is set in different tuning slots (13) to change the effective volume of the resonant cavity (3), thereby realizing tone adjustment.

4. A siren beverage cup according to claim 3, wherein: The tuning stand includes several circumferentially distributed support legs (14), and tuning slots (13) are disposed on the inner sidewalls of the support legs (14).

5. A siren beverage cup according to claim 3 or 4, characterised in that: The bottom of the inner cup (8) is a spherical shape with a downward convex center, and the tuning chip (12) is also spherical.

6. A siren beverage cup according to claim 2, characterized in that: The upper circumferential part of the inner wall of the outer cup (9) has several protrusions (15), and the inner cup (8) is tightly connected to the outer cup (9) through the protrusions (15).

7. A whistle beverage cup according to claim 3 or 4, characterised in that: The lower end of the inner wall of the outer cup (9) is provided with a protruding ring (16), and the lower end of the tuning stand is engaged with the protruding ring (16).

8. A siren beverage cup according to claim 2, characterized in that: The upper end of the inner cup (8) extends beyond the outer cup (9), and a cup lid (17) is provided at the mouth of the inner cup (8).

9. A siren beverage cup according to claim 8, characterized in that: The cup lid (17) is provided with a straw hole (18) for inserting a straw. The straw (7) is detachably inserted into the straw hole (18) and can be used as a blowing tube.

10. A siren beverage cup according to claim 1, characterized in that: The bottom of the sound-emitting membrane protective cover (4) is provided with several through holes (6).
