Detailed Description

The application provides a vice loudspeaker of vehicle, and this vice loudspeaker of vehicle can play friendly suggestion effect to some low-speed pedestrians, has reduced noise pollution to a certain extent.

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As shown in fig. 1 and 2, the present invention provides a vehicle auxiliary horn, which can be used in various vehicles with a main horn, such as automobiles and motorcycles, and the "main horn" refers to an acoustic signal device that must be arranged on the vehicle when the vehicle is manufactured according to national standards or industry standards, namely, a horn included in a conventional finished vehicle product and meeting the normal use function of the vehicle. The vehicle auxiliary horn provided by the embodiment comprises a horn switch 2 and at least one loudspeaker 1 matched with the horn switch 2, wherein the horn switch 2 is connected with the loudspeaker 1 through a radio signal, and the noise value of the loudspeaker 1 is smaller than that of a main horn of a vehicle. Specifically, the noise value of the speaker 1 is generally not more than 70 db, and may be, for example, 40 db to 60 db. Since the noise value of the speaker 1 is smaller than that of the main horn of the vehicle, when the vehicle is driven in an environment where there are many low-speed pedestrians, such as a commercial street, the driver can select the operation of the horn switch 2, which gives a friendly prompt effect to the low-speed pedestrians, prevents the main horn of the vehicle from scaring the low-speed pedestrians, and reduces noise pollution caused by whistling.

As shown in fig. 1, the vehicle sub-horn of the present embodiment includes two speakers 1, which may be respectively disposed at the front left end and the front right end of the vehicle, and the speakers 1 may be mounted to the vehicle through various fixing means, for example, the speakers 1 are provided with an adhesive portion for adhesive connection with the vehicle and fixed to the vehicle by adhesion, or the speakers 1 are provided with mounting holes for mounting bolts and fixed to the vehicle by bolts. As shown in fig. 1, the battery of the speaker 1 supplies power to the wireless module and the microcontroller, the battery may be a battery of a vehicle, or a battery (e.g., a button battery) specially configured for the speaker 1, the wireless module of the speaker 1 is configured to receive a control signal from the horn switch 2, and the wireless module may be a bluetooth module, a WIFI module, or a 2.4G wireless module. After the microcontroller of the loudspeaker 1 obtains the control signal through the wireless module, the driving circuit excites the vibration unit to make sound.

As shown in fig. 2, since the horn switch 2 is connected to the speaker 1 by radio signals, the horn switch 2 can be placed according to personal preference, for example, can be mounted on a steering wheel of a vehicle, or mounted on a driver's seat. Similarly to the speaker 1, the horn switch 2 may be provided with a pasting portion for pasting connection with a vehicle. For ease of operation, the horn switch 2 is generally configured as a push button, the internal circuitry of the horn switch 2 is shown in fig. 2, and a battery, which is typically a battery (e.g., button battery) specifically configured for the horn switch 2, supplies power to the wireless module and the microcontroller, but may also be a battery of the vehicle when the horn switch 2 is integrated into a component of the vehicle, such as a steering wheel. The wireless module of the horn switch 2 is used for transmitting a control signal to the loudspeaker 1, and the wireless module can be a bluetooth module, a WIFI module or a 2.4G wireless module. After the microcontroller of the horn switch 2 obtains an operation instruction of a vehicle driver through the key circuit, the control signal is transmitted out through the wireless module.

The application also provides a vehicle sound signal system, including main loudspeaker, vice loudspeaker, main switch and auxiliary switch, wherein, main loudspeaker and vice loudspeaker all set up in the front end of vehicle, and the noise value of vice loudspeaker is less than the noise value of main loudspeaker, and main switch and auxiliary switch all set up in the steering wheel of vehicle, and main switch is used for controlling main loudspeaker, and auxiliary switch is used for controlling vice loudspeaker.

Specifically, the main switch and the auxiliary switch may be separately provided, that is, the main switch and the auxiliary switch are two independent switches, for example, the main switch is electrically connected to the main horn through a cable, and the auxiliary switch is connected to the auxiliary horn through a radio signal. In addition, the main switch and the auxiliary switch can be designed into the same key, and at the moment, in order to distinguish a use scene, the vehicle sound signal system can further comprise a speed sensor and a shunt controller, wherein the speed sensor is used for detecting the current running speed of the vehicle, the speed sensor is electrically connected with an electric control unit of the vehicle, the shunt controller is also electrically connected with the electric control unit, and when the current running speed is greater than a preset value, the shunt controller conducts a first circuit for connecting the key and the main horn and breaks a second circuit for connecting the key and the auxiliary horn; and when the current running speed is not greater than the preset value, the shunt controller disconnects the first circuit and conducts the second circuit. For example, the preset value is set to 25km/h, and when the running speed of the vehicle is more than 25km/h, the driver presses a horn switch and then the main horn makes a sound; when the running speed of the vehicle is not more than 25km/h, the driver presses the horn switch and then the auxiliary horn makes a sound. Because the noise value of the auxiliary horn is smaller than that of the main horn, noise pollution can be reduced to a certain extent, and a friendly prompt effect is achieved for low-speed pedestrians.

The noise value of the auxiliary horn may be set as required, and in this embodiment, the noise value of the auxiliary horn is not greater than two thirds of the noise value of the main horn, for example, the noise value of the main horn is 90 db, and the noise value of the auxiliary horn should not be greater than 60 db, and may be set to 40 db to 60 db.

The present application further provides a vehicle including the vehicle audible signal system disclosed in the above embodiment.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application.
