Solar power generation pedestrian mute loudspeaker

Abstract

The invention provides a solar power generation pedestrian mute loudspeaker. The loudspeaker comprises a loudspeaker outside a vehicle and a loudspeaker switch inside the vehicle. The external loudspeaker is composed of a solar cell clamping plate, an external loudspeaker shell, a built-in wireless receiving circuit board, a built-in battery, a buzzer, a bottom clamping plate and a clamping plate rotating shaft. The in-vehicle loudspeaker switch is composed of a loudspeaker switch shell, a loudspeaker switch, a wireless transmitting circuit board, a battery and a loudspeaker base. Solar energy is used for supplying power, a wireless signal is transmitted by pressing the loudspeaker switch, the buzzer is triggered to give out low-decibel buzzing sound so as to prompt pedestrians to pay attention to vehicles, and meanwhile the advertisement printing and releasing function is achieved. Pedestrians can be reminded, and noise interference can be reduced.

Description

Technical Field

[0001] The invention relates to a loudspeaker for a car, in particular to a solar-powered pedestrian mute loudspeaker. Background Art

[0002] With the development of urban traffic, the safety issue between vehicles and pedestrians has become increasingly prominent. The traditional vehicle horns are loud and may cause fright and discomfort to pedestrians. The present invention aims to provide a solution that can both remind pedestrians of the presence of vehicles and reduce noise interference. Summary of the invention

[0003] The present invention provides a solar pedestrian mute speaker, which is characterized by comprising an outside speaker fixed to the rear edge of a car engine hood and an inside speaker switch; the outside speaker assembly is composed of a solar cell clamp, a wireless receiver in a shell of the outside speaker, a speaker, a bottom clamp and a clamp rotating shaft; the inside speaker switch assembly is composed of an upper cover of a speaker switch shell, a speaker switch, a wireless transmitter circuit board, a battery and a speaker switch base; the outside speaker is connected and communicated with the inside speaker switch by radio or Bluetooth.

[0004] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Figure 1 Schematic diagram of the switch structure of the external speaker and the internal speaker of the present invention; Figure 2 This is a schematic diagram of the installation locations of the exterior and interior speaker switches.

[0005] When the present invention is used, the solar cell clamp 1 and the bottom clamp 8 connected to the exterior speaker housing 12 are used to clamp the exterior speaker 12 to the rear edge of the car engine cover 14 through the elastic device in the clamp shaft 10, and the solar panel on the solar cell clamp 1 starts to generate electricity to supply the battery and the receiving circuit board in the exterior speaker housing 12, and the exterior speaker 12 is in a standby state; the interior speaker switch housing 2 and the speaker switch base 5 are combined into one to form an interior speaker switch assembly, which is installed on the steering wheel 15 or the instrument panel 16 of the car.

[0006] Pressing the in-vehicle speaker switch 3 triggers the wireless transmitter circuit board 4 to transmit a wireless signal, which connects to the receiving circuit board circuit in the external speaker housing 12, triggering the speaker 9 in the external speaker housing 12 to emit a low-decibel buzzing sound, prompting passers-by to pay attention to the vehicle.

[0007] When the battery 6 of the in-vehicle speaker switch needs to be replaced, the upper cover 2 of the speaker switch is unscrewed to replace the battery 6 in the speaker switch base 5.

[0008] Attached Figure 2This is a schematic diagram of the installation position from the driver's position, viewed through the windshield frame 13 of the automobile.

[0009] Relevant advertisements 7 and 11 can be printed on the exterior speaker housing and the speaker switch.

[0010] The invention has a simple structure and is easy to use, and can realize the pedestrian reminder function and can also be used as an advertisement carrier.
