[0038] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] like Figures 1 to 5 As shown, a vehicle electric horn device comprises a sound-generating component 1, a first loudspeaker 2 and a second loudspeaker 3 which are arranged in sequence;

[0040] The sound-generating component 1 is provided with a sound-generating hole 11;

[0041] An axial sound guide channel 21 and a first spiral sound guide channel 22 are provided in the first speaker 2. The axial sound guide channel 21 is connected to the sound emitting hole 11, and the first spiral sound guide channel 22 is connected to the axial sound guide channel 21.

[0042] A second spiral sound guide 31 is provided in the second speaker 3, and the second spiral sound guide 31 is connected to the axial sound guide 21;

[0043] The axial sound guide channel 21 is used to transmit the sound emitted from the sound hole 11 into the first spiral sound guide channel 22 and the second spiral sound guide channel 31 .

[0044] When using the embodiment of the present application, after the sound-emitting component 1 emits sound, the sound enters the axial sound guide channel 21 through the sound-emitting hole 11, and then the sound is divided from the axial sound guide channel 21, with part of the sound entering the first spiral sound guide channel 22 and the other part of the sound entering the second spiral sound guide channel 31. Figure 6 , in the first loudspeaker 2, part of the sound is amplified by the first spiral sound guide channel 22, and the first loudspeaker 2 broadcasts the sound of the first fundamental frequency; Figure 7 , in the second speaker 3, another part of the sound is amplified by the second spiral sound guide 31, and the second speaker 3 broadcasts the sound of the second fundamental frequency. Therefore, the embodiment of the present application can perform two amplification processes on the sound emitted by the same sound-emitting component 1 through the first speaker 2 and the second speaker 3, so that a car electric horn device can emit dual sound effects. It should be noted that the present application does not limit a sound-emitting component 1 to only being connected to two speakers at the same time. The number of speakers to be connected can be selected according to actual needs, such as adding a third speaker, a fourth speaker, etc.

[0045] Further, it can be understood that the fundamental frequency of the sound finally emitted by the vehicle electric horn device is affected by two parts, one is the part that emits the sound, and the other is the part that amplifies the sound. In the embodiment of the present application, the part that emits the sound is the sound-emitting component 1, and the part that amplifies the sound is the first speaker 2 and the second speaker 3, and the first speaker 2 and the second speaker 3 implemented in the present application are connected to the same sound-emitting component 1. Therefore, referring to Figure 6 and Figure 7 , the length of the first spiral sound guide channel 22 and the length of the second spiral sound guide channel 31 of the embodiment of the present application are set to be one long and one short. Specifically, the length of the first spiral sound guide channel 22 of the first speaker 2 in the embodiment of the present application is shorter than the second spiral sound guide channel 31 of the second speaker 3, so that after the sound emitted by the same sound-emitting component 1 is amplified by the first spiral sound guide channel 22 and the second spiral sound guide channel 31 of different lengths, the first speaker 2 can emit a sound with a higher fundamental frequency, and the second speaker 3 can emit a sound with a lower fundamental frequency, thereby realizing the function of emitting two sounds of different fundamental frequencies at the same time in the embodiment of the present application. Specifically, in the embodiment of the present application, the inner diameters of the first spiral sound guide channel 22 and the second spiral sound guide channel 31 are both set to gradually increase along the direction of sound propagation, so as to facilitate the regulation of the curvature and length of the first spiral sound guide channel 22 and the second spiral sound guide channel 31.

[0046] Reference Figure 1 and Figure 2 It can be understood that in order to adjust the volume of the sound entering the first speaker 2 and the second speaker 3, the embodiment of the present application is also provided with a connecting block 4 between the first speaker 2 and the second speaker 3, and a shunt hole 41 is provided at the center of the connecting block 4. One end of the shunt hole 41 is connected to the sound outlet of the axial guide channel 21, and the other end is connected to the sound inlet of the second spiral guide channel 31. In the embodiment of the present application, the aperture size of the shunt hole 41 is the same as the aperture size of the sound outlet of the axial guide channel 21, so that the sound can enter the shunt hole 41 through the axial guide channel 21. It should be noted that the shunt hole 41 provided on the connecting block 4 can be adjusted in size according to actual needs. The larger the shunt hole 41, the larger the air flow rate allocated to the sound in the second speaker 3, so that the second speaker 3 can emit a louder sound. Correspondingly, at this time, the air flow rate of the sound in the first speaker 2 is also smaller, that is, the sound emitted by the first speaker 2 is smaller. Therefore, by adjusting the size of the diverter hole 41 , the airflow rates of different sounds of the first speaker 2 and the second speaker 3 are adjusted, so that the volumes of the sounds emitted by the first speaker 2 and the second speaker 3 are different.

[0047] Furthermore, in order to ensure that the sound can only enter the sound entrance of the second spiral sound channel 31 through the diversion hole 41, it is necessary to further limit the size of the diversion hole 41 opened on the connecting block 4, and control the sound entrance diameter of the second spiral sound channel 31 to be larger than the aperture of the diversion hole 41, so that when the sound is diverted, the sound can only enter the sound entrance of the larger second spiral sound channel 31 through the smaller diversion hole 41.

[0048] At the same time, the connecting block 4 also serves to improve the structural stability after the first loudspeaker 2 and the second loudspeaker 3 are connected.

[0049] Specifically, refer to Figure 2 and Figure 8 In the embodiment of the present application, the connection block 4 is configured as a columnar structure with two end faces. The surface of the first speaker 2 for connecting with the connection block 4 is configured as a first connection slope 23, and one end face of the connection block 4 is configured as a second connection slope 42. The second connection slope 42 is not perpendicular to the axis of the connection block 4, and the slopes of the first connection slope 23 and the second connection slope 42 are configured to be consistent, so that the first connection slope 23 can fit tightly with the second connection slope 42, and a stable connection between the first speaker 2 and the connection block 4 is achieved through an ultrasonic welding process.

[0050] The other end surface of the connecting block 4 is set to a connecting plane 43, and the connecting plane 43 is perpendicular to the axis of the connecting block 4. The bottom of the second speaker 3 is connected to the connecting plane 43, and the second speaker 3 is stably connected to the connecting block 4 through an ultrasonic welding process. Thus, the first speaker 2, the connecting block 4 and the second speaker 3 are welded in sequence to form a whole, which can facilitate the processing and installation of the vehicle electric horn device.

[0051] Reference Figures 4 to 7 It can be understood that, in order to reduce the weight of the vehicle electric horn device, the first speaker 2 and the second speaker 3 used in the embodiment of the present application are both provided with weight-reducing cavities. Specifically, in the embodiment of the present application, five first weight-reducing cavities 26 are provided in the first speaker 2, and one second weight-reducing cavity 32 is provided in the second speaker 3. Accordingly, the first speaker 2 with a larger number of weight-reducing cavities has a shorter first spiral sound guide 22, and the second speaker 3 with a smaller number of weight-reducing cavities has a longer second spiral sound guide 31. Adjusting the size and number of the weight-reducing cavities can effectively regulate the size and length of the first spiral sound guide 22 and the second spiral sound guide 31.

[0052] Reference Figures 2 to 4 In the embodiment of the present application, the first speaker 2 and the sound-emitting component 1 are fixed by snap-fitting. Specifically, a clamping ring 12 is provided on the outer circumference of the surface of the sound-emitting component 1 for connecting with the first speaker 2, and a clamping ring 24 is provided on the outer circumference of the surface of the first speaker 2 for connecting with the sound-emitting component 1. The clamping ring 12 and the clamping ring 24 are arranged correspondingly, and the outer diameter of the clamping ring 12 is equal to the inner diameter of the clamping ring 24. A plurality of elastic buckles 25 are connected to the inner wall of the clamping ring 24. In the embodiment of the present application, four elastic buckles 25 are arranged and arranged circumferentially on the inner wall of the quadrant of the clamping ring 24. When the clamping ring 12 is squeezed inside the clamping ring 24, the elastic buckle 25 can be clamped on the bottom of the outer side of the clamping ring 12 by rebounding after squeezing, that is, the elastic buckle 25 is limited to the side of the clamping ring 12 away from the first speaker 2, so that the fixed connection between the clamping ring 12 and the clamping ring 24 is achieved.

[0053] Reference Fig. 9The sound-emitting component 1 used in the embodiment of the present application is an existing structure, including a shell 13 and a sound-emitting diaphragm 14. The shell 13 includes a top cover 131 and a bottom shell 132. The sound-emitting hole 11 is opened on the top cover 131, and the sound-emitting diaphragm 14 is located in a chamber formed by the top cover 131 and the bottom shell 132. The sound-emitting diaphragm 14 vibrates through the action of the electric field and the magnetic field. The sound-emitting diaphragm 14 generates a sound airflow during the vibration process. The sound airflow enters the first speaker 2 and the second speaker 3 through the sound-emitting hole 11, and then emits sound after being amplified by the first speaker 2 and the second speaker 3. In the process of using the embodiment of the present application, a specific sound-emitting component 1 can be selected for use according to the size of the first speaker 2 and the second speaker 3.

[0054] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present application is defined by the appended claims and their equivalents.
