The invention discloses a touch automobile alarm comprising a direct current power supply, a touch piece, a switch, an alternative switch, a first capacitor, a second capacitor, a first resistor, a second resistor, a voltage regulator tube, a relay, a transformer, a first time base integrated chip, a second time base integrated chip, a triode and a loudspeaker. When the first switch of the power switch is opened, an alarm circuit stops working due to lack of power supply. After the automobile is stopped, the first switch is closed and the power supply is in connection. Since the first time base integrated chip is designed according to an operation mode of a trigger, the output terminal has a low level; the relay has no power and does not work; a subsequent circuit does not work; and the circuit is in a monitoring state. Compared with the prior art, the touch automobile alarm has the advantages of simple circuit structure, small electronic component quantity and low cost. By adopting the induction touch alarm method, an alarm signal is given out as long as a person touches the automobile. The touch automobile alarm is quick in response and has promotion and application values.
