Abstract
The invention relates to a compass with a buzzer. The compass is used for solving the problem that the blind people cannot use the traditional compass. The compass with the buzzer structurally comprises a shell, a buzzer, a light-emitting diode, a photosensitive sensor and a compass, wherein the shell is a wedge-shaped block with a small end face on one side and a big end face on the other side; the compass and the buzzer are arranged on the upper surface of the shell; the light-emitting diode is arranged on a finger head of the compass; the photosensitive sensor is arranged on a side wall close to the small end face of the shell, of the compass; and the photosensitive sensor is electrically connected with the buzzer. The blind people only need to rotate the compass with the buzzer; when a finger head of the compass is pointed to the north, the light-emitting diode is in butt joint with the photosensitive sensor and the photosensitive sensor can supply a signal for making the buzzer sound, so that the pointing direction of the shell held by the blind people is toward the north direction; and the blind people can independently distinguish the direction.
Description
Technical field
The present invention relates to a kind of compass, a kind of specifically compass with hummer.
Background technology
Compass is one of common tool of taking one's bearings.But for the blind person, owing to cannot see needle, so can't take one's bearings through compass.
Summary of the invention
The object of the present invention is to provide a kind of compass, mainly solve the problem that the blind person can't use existing compass with hummer.
The present invention solves the technical scheme that its technical matters takes: the compass of band hummer, and its structure comprises housing, hummer; Light emitting diode, light sensor and compass; Described housing is the big wedge of the little opposite side end face in a side end face, and the housing upper surface is provided with compass and hummer, and the syringe needle of described compass is provided with light emitting diode; On the sidewall of compass near the housing small end face, be provided with light sensor, described light sensor is electrically connected with hummer.
The invention has the beneficial effects as follows: adopt light signal to judge the mode of direction, solved compass and need see that pin distinguishes the problem of direction.The blind person only need hold the present invention and rotate, and when the syringe needle of compass pointed to the north, light emitting diode just in time docked with light sensor, and light sensor provides signal to make hummer send the sound, and the hand-held housing direction pointed of blind person's this moment is the north.The blind person also can independently be taken one's bearings.
Description of drawings
Fig. 1 looks synoptic diagram for master of the present invention.
Among the figure: 1 housing, 2 hummers, 3 light sensors, 4 light emitting diodes, 5 compasses.
Embodiment
As shown in Figure 1.The compass of band hummer, its structure comprises housing 1, hummer 2; Light emitting diode 4, light sensor 3 and compass 5; Described housing 1 is the big wedge of the little opposite side end face in a side end face, and housing 1 upper surface is provided with compass 5 and hummer 2, and the syringe needle of described compass 5 is provided with light emitting diode 4; On the sidewall of compass 5 near housing 1 small end face, be provided with light sensor 3, described light sensor 3 is electrically connected with hummer 2.
During use; The blind person only need hold housing 1 and rotate; When the syringe needle of compass 5 pointed to the north, the syringe needle of compass 5 pointed to the small end face of housing simultaneously, and this moment, light emitting diode 4 just in time docked with light sensor 3; Light sensor 3 provides signal to make hummer 2 send the sound, reminds the small end face direction pointed of the hand-held housing 1 of blind person's this moment to be the north.The blind person can independently be taken one's bearings.Adopt light signal to judge the mode of direction, solved compass and need see that pin distinguishes the problem of direction.
