Abstract

A laser rangefinder with a voice control function has a housing, a voice sensor module, a measure module, a circuit board and a display module. The housing has a voice-receiving hole and a screen. The voice sensor module receives voice commands through the voice-receiving hole. The measure module produces and emits a laser beam toward an object and then receives the laser beam reflected from the object. The circuit board judges the voice command sent by the voice sensor module to activate the measure module for calculating and determining a distance between the laser rangefinder and the object based by a time interval of the laser beam traveling toward and returning from the object. The display module shows a determined result on the screen.

Claims

1. A laser rangefinder with a voice control function comprising:

a housing having

an outer surface;

an inner space;

a middle;

a rear end;

a voice-receiving hole defined through the outer surface of the housing;

a screen mounted securely on the outer surface of the housing;

multiple functional buttons mounted on the outer surface at the middle of the housing; and

a threaded section defined around the outer surface at the rear end of the housing;

a voice sensor module mounted securely in the inner space of the housing and aligning with the voice-receiving hole to receive voice commands spoken by users;

a manual input module mounted securely in the inner space of the housing, electrically connected with the functional buttons to receive manual commands conveyed through the functional buttons;

a measure module mounted securely in the inner space of the housing and having

a laser module mounted in the inner space of the housing to produce and to emit a laser beam toward an object; and

an optoelectronic module mounted in the inner space of the housing to receive the laser beam reflected from the object;

a circuit board mounted securely in the inner space of the housing, electrically connected with the voice sensor module, the manual input module and the measure module to receive and to judge the voice commands sent from the voice sensor module or manual commands sent from the manual input module, and to activate the measure module for steps of distance determination and to calculate and to determine a distance between the laser rangefinder and the object based by a time interval of the laser beam traveling toward and returning from the object;

a display module mounted securely in the inner space of the housing, electrically connected with the screen and the circuit board to show a determined result on the screen; and

an illumination mounted securely in the rear end of the housing to provide the laser rangefinder an illumination function and having a body screwed with the threaded section of the housing.

2. The laser rangefinder as claimed in claim 1, wherein the housing has multiple ribs formed on the outer surface at the middle of the housing.
