Abstract
The utility model relates to a kind of earphone reminiscences, comprise the amplifier amplified for the audio frequency detector of Test earphone external voice and the voice signal for being detected by audio frequency detector, described audio frequency detector is located on the shell of earphone, the input of amplifier connects audio frequency detector, output frames connecting with headphone loudspeaker.When there being people to call out user or dangerous warning sound, when the audio frequency detector on earphone outer covering detects frequency larger sound section, by amplifier, voice signal being amplified, then importing the loudspeaker of earphone into, have people in calling to remind user or danger.
Description
Technical field
The utility model relates to a kind of earphone reminiscences, puts on earphone, and the sound amplification of the external world being called out user notifies user, avoids putting on earphone and cannot hear that extraneous sound produces potential safety hazard.
Background technology
At present a lot of young man on and off duty, go window-shopping, all like bringing earphone to listen to the music, sometimes volume of music put excessive, all possibly cannot hear when calling out user when there being people or have car to honk below, not replying others may be rude to others, or causes very large potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of earphone reminiscences, with at least one aspect that solves the problem.
According to one side of the present utility model, a kind of earphone reminiscences, comprise the amplifier amplified for the audio frequency detector of Test earphone external voice and the voice signal for being detected by audio frequency detector, described audio frequency detector is located on the shell of earphone, the input of amplifier connects audio frequency detector, output frames connecting with headphone loudspeaker.
After adopting such structure, when there being people to call out user or dangerous warning sound, when the audio frequency detector on earphone outer covering detects frequency larger sound section, by amplifier, voice signal is amplified, import the loudspeaker of earphone again into, with remind user have people calling or danger.
As further improvement of the utility model, earphone outer covering being also provided with the control switch opened and closed for controlling audio frequency detector, when not needing to open this reminiscences, can being closed.
Accompanying drawing explanation
Fig. 1 is the utility model structure diagram;
Fig. 2 is the utility model FB(flow block);
Fig. 3 is circuit theory diagrams of the present utility model.
Embodiment
Illustrate that the utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
In Fig. 1, Fig. 2, Fig. 3, a kind of earphone reminiscences, comprise the amplifier 2 amplified for the audio frequency detector 1 of Test earphone external voice and the voice signal for being detected by audio frequency detector 1, described audio frequency detector 1 is located on the shell of earphone, the input of amplifier 2 connects audio frequency detector 1, output frames connecting with headphone loudspeaker 4.
After adopting such structure, when there being people to call out user or dangerous warning sound, when the audio frequency detector 1 on earphone outer covering detects frequency larger sound section, by amplifier 2, voice signal is amplified, import the loudspeaker 4 of earphone again into, with remind user have people calling or danger.
Described audio frequency detector 1 is for the stronger acoustic signals within the scope of neighbouring 5 meters being detected, and the power supply 5 that its electric energy is carried by musical instruments is supplied.Current young man puts on earplug extraneous voice signal of listening to the music and does not almost hear, be easy to like this cause the trouble than necessity and danger, this device can collect the stronger acoustic signals within the scope of neighbouring 5 meters, reminds user at any time, brings convenience to user.
Meanwhile, earphone outer covering being also provided with the control switch 3 opened and closed for controlling audio frequency detector 1, when not needing to open this reminiscences, can being closed.User need absolute quiet time, can turn off control switch 3, audio frequency detector 1 power supply 5 cuts off, and amplifier 2 quits work.Just can be used as common headphones to use.
These are only specific embodiment of the utility model, but technical characteristic of the present utility model is not limited thereto.Any based on the utility model, for realizing substantially identical technique effect, done ground simple change, equivalent replacement or modification etc., be all covered by among protection range of the present utility model.
Claims (3)
