When the vehicle passes around the pedestrian, the sound 5 generated by the sound outlet 114 can be used as the warning sound p to remind the pedestrian to pay attention to the approaching vehicle. @本'Pedestrians can easily judge the proximity of the vehicle' to prevent early. In the embodiment, the sound outlet 114 is a racquet opening having a large cross-sectional area to increase the range of sound amplification. Please also refer to the first! Fig. 2 and Fig. 2 show a schematic cross-sectional view of the tuning tube 116 applied to the creation of the f along the Η and line. In the second example, the plurality of tuning tubes 116 can be disposed inside or around the sound outlet 114. The tuning tube 116 is used to adjust the frequency or tone of the natural sound source 16〇::r丨14, for example, when the tuning tube 116a and the plurality of buttons U6b are combined, the tuning sounds i&ifi are generated by the inherent sound source (10). The frequency of the sound S will be relatively "long" with the length of the long tube a, making the tone relatively low; or higher with the shorter length of the display: the tone is relatively high. = mouth == by Adjusting the length of the tuning tubes 116 can be changed by the variability. The same sound quality warning tone p, so that the warning tone P has the selection of the nip tuning tube 116 can be changed according to the customer's demand two == the sound of the sound 8 of the sound. For example, if the frequency of the sound s generated by the source (10) is low... the official mc or the treble double-pass pipe 116d is used as the tone = i picture) 'the sound generated by the natural sound source 16Q of the sound outlet (1); Relatively high; if, if the collected sound of s is specific to k - there is S 'original, 160 produces S frequency material (four), you can use the bass single pass tube suit, or the bass double M405993 = as the tuning tube ( See Fig. 1), so that the sound of the sound s produced by the sound source 114 is relatively It is relatively low. Therefore, this creation is made up of different types of tuning tubes 116, and the warning sounds p of different sound qualities can be generated by the sound outlet 114, so that the warning sounds have variability. - In the above, the tuning tube 116 is an additional kit, which is not a necessary choice for the present embodiment. If the tuning tube 116 is not needed, it can be removed from the connection of the sound propagation tube body 11G. Please refer to the 3gj, another embodiment of the New Zealand without I In addition, the tuning tube U6 is added to adjust the frequency or timbre of the sound S generated by the natural sound source 16 出 through the sound σ 114. Now, the sound amplification device 120 and the airflow introduction tube are introduced first. 130 and the operation mode of the valve 14 。 The sound amplifying device 120 is used to amplify the volume of the sound 8 generated by the natural sound source 16 。. Referring to the i-th image, the sound reinforcement device 12 〇 includes, for example, one or more resonators 122, 124 And 126, which can be disposed around the sound inlet 112 or the sound outlet 114. The resonance frequency of the resonators 122, 124, and 126 is related to the size of the opening of the crying and the size of the cavity volume. For example, the opening is small and empty. i When the volume is large, the 'resonator The resonance frequency is low; the opening is large and the cavity volume is small, and the resonant frequency of the resonator is high. When any frequency of the sound s generated by the natural sound source 16 一致 is consistent with the resonance frequency of the resonators 122, 124 and 126, resonance is generated ( Resonance) amplifies the original sound source 16 〇 original volume. Therefore, the present invention can amplify the sound generated by the natural sound source 160 by arranging a plurality of resonators 122, 124 and 126 having different cavity sizes or different opening calibers. f S' makes the volume emitted by the sound D 114 more obvious. The air flow introduction pipe body 130 is used to introduce the external air flow F. Referring to FIG. 2, the airflow introduction pipe body 130 has a passage 132. The passage 132 is connected to the 7 M405993 in the sound propagation tube body 11G for guiding the external airflow F into the person to adjust the opening and closing of the valve 140. For example, the opening of the airflow introducing pipe body 13 is oriented toward the vehicle traveling direction. When the vehicle is traveling, the external airflow F opposite to the traveling direction of the vehicle can enter the channel 13 via the opening 134. The faster the flow rate of the external airflow F is. Conversely, the rut = the slower the flow rate of the milk. Further, the flow rate of the external air flow F is also related to the pipe diameter of the air flow introducing pipe body 13G. When the diameter of the airflow guiding pipe 13() is the same, the flow velocity of the external airflow F in the passage 132 can be kept consistent. However, when the pipe diameter of the airflow introducing pipe body 13 is changed, for example, a venturi, the outside The flow rate of F in channel 132 will also change. Therefore, the present invention can be used as the basis for the operation of the valve 14 by the vehicle speed and the diameter of the airflow introduction pipe body 13'. Referring to Figure 1, the valve 140 is disposed at the junction of the passage 132 and the sound transmission tube 11G. When the flow rate of the external airflow F is greater than a lower limit, for example, the vehicle speed is higher than 40 km/h, the target airflow F is completely closed by the external airflow F to block the sound S generated by the natural sound source 160. The sound propagates the propagation path inside the tube body 11; conversely, when the flow rate of the external air flow F is less than the lower limit value, for example, when the vehicle speed is between 〇km/hr and 40km/hr, the sound propagation tube body is ιι〇 The valve Π 140 is in a fully open state or a partially closed state to control the volume S of the sound S generated by the natural sound source 160 to propagate to the sound outlet 114. Therefore, the flow rate of the external airflow F when the handle is traveled, that is, the opening degree of the valve UO can be automatically controlled, so that the inherent sound source 16〇 produces a change in the volume of the valve 140. In the M405993 example, when the vehicle is driving at a low speed

The volume is getting smaller. In addition, when the button is on the 40-kilometer 7-small phase, since the tire sounds at this time, there is no need to issue an additional warning tone to the pedestrian, and the opening of the flow rate of the external airflow F automatically adjusts the opening of the valve M i4Q. If the column is fully closed, the volume of the warning tone p emitted from the sound outlet 114 is small. An embodiment of the present invention - Referring to Figure 4, there is shown a simplified schematic diagram of a vehicle warning sound device in accordance with a second embodiment of the present invention. This embodiment differs from the first embodiment in that the vehicle warning sound device HM) further includes a vibration member 15A disposed on an inherent sound source 160 of the vehicle, such as a power motor, a gearbox or a wheel hub. The fixed structure of the body is used to transmit and amplify the structural vibration sound caused by the vibration of the inherent sound source 160 of the vehicle itself during operation. The vibrating member 150 is, for example, a member including a metal foil or a vibrating blade 152 at one end, and transmits the vibration sound to the acoustic tube body 110 in accordance with the vibration of the natural sound source 160. Therefore, the present creation is not limited to collecting only the air sound S generated by the inherent sound source 160 of the vehicle itself, and can also collect the M405993 vibration sound generated by the mechanical vibration. For the third embodiment, please refer to FIG. 5, which is depicted in accordance with the third creation. A simplified schematic diagram of the vehicle alarm device of the embodiment. The vehicle warning sound device 2 includes a sound transmission propagating body 210, a sound amplification device 220, and a valve controller 230 to = a valve 240. The arrangement of the sound transmitting tube body 21, the sound amplifying device 22, the tuning tube 216, and the valve 240 is substantially the same as that of the first embodiment, and will not be described again. This embodiment differs from the first embodiment in that the opening of the valve 240 is controlled by the valve control thief 230 to adjust the volume of the sound 8 generated by the built-in sound source 160 through the valve 24 。. The valve controller 230 is actuated, for example, by mechanical force or by electronic signals. For example, the valve controller 230 can adjust the opening of the wide door 24 根据 according to an electronic throttle signal, a vehicle speed sensing signal, or a position of the accelerator pedal. When the vehicle is low, the creation of the valve is controlled by the valve controller 23 () to adjust the opening of the valve 2), so that the warning sound p emitted from the sound outlet 2l4 has the maximum effect of the two-two warning. In addition, when the vehicle speed is increased, the present invention f; two: the controller 230 automatically adjusts the opening degree of the valve 240 (for example, the degree becomes smaller), so that the warning sound P of the sound outlet 214 is gradually reduced.
