A controller (27) mounted on a small-sized hydraulic excavator (1) includes an engine restart section (27E) that restarts an engine (10) when a horn switch operation determining section (27B) determines that a horn switch (14) is operated and a gate lock lever position determining section (27C) determines that a gate lock lever (16) is at a lock position in a case where a restart standby time determining section (27A) determines that restart standby time (T2) does not yet elapse after the engine (10) is automatically stopped by an idling stop function, and a power supply stopping section (27F) that stops an electric power supply of a vehicle body (2, 3) when the restart standby time determining section (27A) determines that the restart standby time (T2) has elapsed.

The present disclosure relates to a car audio information transmitter, including: a main controller, an audio receiver, an audio, transforming module, a wireless transmitter, and a frequency adjustment module. The audio receiver connects to the main controller. The audio transforming module connects to the audio receiver and is configured to transform the audio signals. The wireless transmitter connects to the audio transforming module and is configured to transmit the transformed audio signals to a wireless receiver of a can The frequency adjustment module connects to the audio transforming module and is configured to adjust a frequency of the audio signals. The car audio information transmitter is capable of accessing to the adjusting mode by one operation and adjusting an amplitude of the audio signals. As such, the complicated operations may be avoided, and the driving safety may be improved.

The present invention relates to a manner knock horn device for a vehicle, and more particularly to technology that replaces an existing horn installed in a vehicle, enables accurate information transfer between drivers, overcomes the problem of causing discomfort due to a loud horn sound, and is easily installable in the vehicle. The manner knock horn device for a vehicle includes: a switch device installed in the inside of a vehicle, and configured such that one or more voice messages are stored therein in advance and it transmits voice message information by means of an operation button; and a speaker device installed to be attached to the vehicle at a location away from the switch device, and configured to be wirelessly connected to the switch device and to generate a voice signal to the outside in accordance with the transmitted voice message information.
