Abstract
The utility model relates to an outside sound warning system of automobile body. At present, the requirements of the external warning sound product of the automobile body on sound parameters and functions are different, so that 3 products and 4 loudspeakers are loaded on the automobile at the same time at the present situation. A car body external sound warning system comprises: BCM (1), control box (2), loud speaker (3), low-pitched loudspeaker (4) and speaker loudspeaker (5), BCM is connected with the control box, and the control box is connected with loud speaker, low-pitched loudspeaker and speaker respectively, and BCM is the automobile body controller, installs IC pronunciation chip in the control box, and loud speaker, low-pitched loudspeaker and speaker are installed and are constituteed sound warning system in the automobile body outside. The utility model discloses be applied to automobile field.
Description
Technical Field
The utility model relates to an outside sound warning system of automobile body.
Background
The automobile has more parts with the sound warning function, and the parts can be divided into acoustic parts (such as instrument warning sound and the like) for warning drivers and passengers in the automobile body and acoustic parts (such as a driving warning horn, an anti-theft warning horn, a pedestrian prompting device and the like) for warning other vehicles and pedestrians outside the automobile body according to different installation positions. Because the requirements of the external warning sound product of the automobile body on sound parameters and functions are different, the current situation is that 3 products, 4 loudspeakers are loaded on the automobile at the same time.
Disclosure of Invention
The utility model aims at providing an outside sound warning system of automobile body.
The above purpose is realized by the following technical scheme:
a car body external sound warning system comprises: BCM, control box, high-sound loudspeaker, low-sound loudspeaker and speaker loudspeaker, BCM with the control box connect, the control box respectively with high-sound loudspeaker low-sound loudspeaker with speaker loudspeaker connect, BCM be the automobile body controller, the control box in install IC pronunciation chip, high-sound loudspeaker low-sound loudspeaker with speaker loudspeaker install and constitute sound warning system in the automobile body outside.
In the external sound warning system for the automobile body, the loudspeaker is a sounding device with complex sound or warning sound with high sound quality requirement.
In the external sound warning system for the vehicle body, the high-sound horn adopts a high-sound-pressure-level horn to perform a warning device of the vehicle.
The external sound warning system of automobile body, low-sound loudspeaker adopt low-sound pressure level loudspeaker to carry out pedestrian's warning device.
The utility model has the advantages that:
1. the utility model discloses the outside sound warning system of automobile body reduces the acoustics part of the outside warning of automobile body to 3: 1 high sound pressure level driving horn, 1 low sound pressure level loudspeaker warn the pedestrian, 1 loudspeaker horn is used for producing the warning sound of other complicacies such as theftproof alarm sound or high tone quality demand.
The utility model discloses can solve the higher warning sound production structure of complicacy and sound quality requirement and adopt the speaker, leave the data of source sound in IC pronunciation chip. The single chip microcomputer calls a required sound source file according to the received control command, and then the audio waveform is loaded onto the loudspeaker through the power amplifier, so that various warning sounds are emitted. And for vehicles and pedestrians, a loudspeaker with a high sound pressure level or a loudspeaker with a low sound pressure level is adopted for warning according to the information of the current vehicle speed.
The utility model has the characteristics of it is following:
(1) the sound parameters, such as frequency and sound pressure level, of the driving warning horn, the anti-theft warning horn, the pedestrian prompting device, the door opening and closing prompting device and the like are different. Therefore, the product adopts the loudspeaker as a sounding device of warning sound with complex sound or higher sound quality requirement, adopts the loudspeaker with high sound pressure level to warn vehicles, and adopts the loudspeaker with low sound pressure level to warn pedestrians;
(2) because the product contains more sound elements and is difficult to modulate through PWM, the product adopts an IC voice chip to store and process sound, and meets the requirements of various sounds;
(3) according to the speed information, whether a high-sound-pressure-level horn is adopted for other vehicle warning or a low-sound-pressure-level horn is adopted for pedestrian warning is automatically identified.
(4) Because the functions of several sounding devices are integrated in one system, the space required by loading can be greatly reduced, and the loading cost is saved.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of the original structure of fig. 1.
In the figure: 1. BCM, 2, control box, 3, loud speaker, 4, low-sound speaker, 5, speaker, 6, alarm, 7, pedestrian warning indicator.
The specific implementation mode is as follows:
example 1:
a car body external sound warning system comprises: BCM1, control box 2, loud speaker 3, low-sound speaker 4 and speaker 5, BCM with the control box connect, the control box respectively with loud speaker low-sound speaker with speaker connect, BCM be the automobile body controller, the control box in install IC pronunciation chip, loud speaker low-sound speaker with speaker install and constitute sound warning system in the automobile body outside.
Example 2:
according to the sound warning system outside the vehicle body in the embodiment 1, the loudspeaker is a sounding device with complex sound or warning sound with high sound quality requirement.
Example 3:
according to the sound warning system outside the vehicle body in the embodiment 1 or 2, the loud speaker adopts a high sound pressure level speaker to perform a warning device of the vehicle.
Example 4:
according to embodiment 1 or 2 or 3 of the external sound warning system for vehicle body, the low-sound horn adopts a low-sound pressure level horn to warn the pedestrian.
Claims (4)
1. A car body external sound warning system comprises: BCM, control box, high-sound loudspeaker, low-sound loudspeaker and speaker loudspeaker, characterized by: BCM with the control box connect, the control box respectively with high sound loudspeaker low sound loudspeaker with speaker loudspeaker connect, BCM be the automobile body controller, the control box in install IC pronunciation chip, high sound loudspeaker low sound loudspeaker with speaker loudspeaker install and constitute sound warning system in the automobile body outside.
2. The vehicle body exterior sound warning system according to claim 1, wherein: the loudspeaker is a sounding device with complex sound or warning sound with high sound quality requirement.
3. The vehicle body exterior sound warning system according to claim 1, wherein: the high-sound horn adopts a high-sound pressure level horn to carry out a warning device of the vehicle.
