FIGURE 1 shows a whistle (1) of a generally known exterior shape being virtually identical to the shape of the Applicant company's ACME 210 ½ whistle. Even so, the outward appearance of the whistle (1) is substantially very different to the known ACME 210 ½ whistle and the internal structure is very different. Whistle (1) has a polycarbonate framework or structure (2) onto which is injected moulded an elastomeric material covering or coating (3) (such as neoprene rubber or like). The structure (2) comprises upper and lower polycarbonate components that are assembled together prior to the coating (3) being applied. Parts of the internal structure (2) remain exposed in the completed whistle (1).

The utility model discloses a hand-free whistle device, comprising a first support made of an elastic material and used for being fixed on the head of a wearer; the second support comprises a first end movably connected to the tail end of the first support through a damping rotating assembly and a second end used for being connected with a whistle; and the whistle is arranged at the second end and is configured to be capable of driving the whistle to move to the mouth of the user by rotating the second bracket. The whistle is fixed on the head of a user through the arrangement of the first bracket and the second bracket, and when the whistle needs to be used, the second bracket is shifted, so that the whistle is driven by the second bracket to move to the mouth of the user, the two hands of the user are liberated through the mode, the whistle does not need to be continuously held by hand, and the whistle blowing action can be completed only through one step; and the structure is relatively simple and practical, the manufacturing cost is extremely low, the increased cost for a user is very low, the reliability is relatively high, and large-scale popularization is facilitated.

The utility model discloses an emergency help-seeking sounding whistle, which is characterized in that sounding cavities are arranged on the left side and the right side in a whistle body, impact metal balls are arranged in the sounding cavities, side air outlet holes are arranged on the left side and the right side of the whistle body, and the side air outlet holes are respectively communicated with the sounding cavities on the same side. Front air outlet holes are formed in the left side and the right side of the front end of the whistle body and communicate with the sound production cavities on the same side, an air inlet cavity is fixedly installed at the rear end of the whistle body, and a circular air inlet cavity is formed in the center in the air inlet cavity and communicates with the two sound production cavities at the front end. A blowing nozzle is installed on the side edge of the air inlet cavity through a one-way air inlet valve, and the inner side of the one-way air inlet valve communicates with the side edge of the circular air inlet cavity. According to the utility model, the design is reasonable, the sounding frequency of the whistle is improved through the two sounding cavities and the internal impact metal ball, the possibility of being found is improved, and the whistle can be activated in two modes, so that the situation that the whistle cannot be used after the mouth of a user is injured is avoided.

The utility model discloses a whistle. The whistle comprises a whistle body, the front end of the whistle body is provided with a sound outlet, the inner side of the sound outlet is provided with a second air hole, the other inner side of the sound outlet is provided with a first air hole, the first air hole is located in the axial orthographic projection area of the second air hole, and one end of the whistle body is provided with a mouthpiece communicated with the first air hole; a hollow part is arranged at the rear end of the whistle body, the whistle further comprises a sealing cover, the sealing cover covers the hollow part, and a resonant cavity is formed between the sealing cover and the hollow part; the mouthpiece, the first air hole, the second air hole, the resonant cavity and the sound outlet form an airflow channel; according to the utility model, the sealing cover and the whistle body can be manufactured and installed independently, and a user can flexibly adjust the shape and the space size of the resonant cavity according to actual requirements by replacing sealing covers with different shapes or sizes, so that the volume and the tone of sound are optimized; by means of the design, the problem that in the prior art, acoustic performance cannot be adjusted due to the fact that the resonant cavity is fixed is solved.

We provide disaster prevention equipment that allows a whistle and a receiving tray to be secured together with a locking mechanism. [Solution] A self-adhesive disaster prevention whistle characterized by fixing the whistle body and the receiving tray with a locking mechanism, and having an adhesive member provided on the back surface of the receiving tray.

The utility model provides a sound production type step, relates to the technical field of landscape decoration structures, and aims to solve the problems that the step serving as a common landscape element only has a single passing function, lacks interactivity and interestingness, lacks auditory experience and cannot provide rich auditory enjoyment for pedestrians. Comprising a step support frame, a bearing support, a step platform and a bearing support cylinder, an assembling open groove is formed in the top of the step support frame; a positioning supporting groove is formed in the bottom of the bearing support; the step platform is arranged at the top of the step support frame; the bearing supporting cylinder is fixedly arranged on the inner side of the fixed bearing groove, a positioning pressing ring is fixedly arranged on the outer side of the bearing supporting cylinder, and a ventilation supporting cylinder is fixedly arranged at the bottom of the bearing supporting cylinder; the ventilation supporting cylinder moves on the inner side of the bearing bottom cylinder, so that gas on the inner side is compressed, the gas drives the sound production whistle through the ventilation supporting cylinder to produce sound with specific audio frequency, the step platform can be supported through the supporting spring to be reset, and sound production playing of the step when the step bears pedestrians is achieved.

A road vehicle (1) having: a bottom wall (6), which, in use, faces a road surface; a body (3), which delimits a passenger compartment; and an aerodynamic sound generation system (7), which is configured to generate sounds making use of the head wind, namely the movement of air relative to the road vehicle (1) generated by the forward movement of the road vehicle (1).

The utility model relates to the technical field of life-saving articles, in particular to an outdoor help-seeking whistle with an orientation function, which comprises a base plate, a whistle body and a compass are mounted on the base plate, the top end of the compass is rotatably connected with a sleeve shell, the top end of the sleeve shell is provided with an indexing ring, and at least one side of the base plate is arranged to be a straight edge; according to the scheme, the whistle can be blown to call for help in an emergency, the compass can be used for finding the direction, the straight edge and the index ring can be used in a matched mode to measure the azimuth angle of the position, various lifesaving means are provided for outdoor enthusiasts, the outdoor requirements are met, all the functional parts are integrated, and carrying is convenient.

Figure 1 shows a whistle (1) with a commonly known external shape, substantially identical to the shape of the applicant company's ACME210 1 / 2 whistle. However, the outward appearance of whistle (1) is substantially very different from the known ACME210 1 / 2 whistle, and the internal structure is also very different. Whistle (1) has a polycarbonate frame or structure (2) to which an elastomer material cover or coating (3) (such as neoprene rubber) is injection molded. Structure (2) comprises upper and lower polycarbonate components assembled together before the coating (3) is applied. The portion of the internal structure (2) remains exposed in the finished whistle (1).
