Abstract
The utility model provides a hearing aid capable of distinguishing sound direction. The traditional hearing aid is provided with only one microphone which picks up sound signals and one earphone which replays the sound signals, and therefore, the sound source positioning can not be achieved. The utility model uses the principle of stereo sound and adopts two microphones which are divided into a left and a right channels which replay the sound signals, two microphones are respectively arranged on the left ear and the right ear of a user, and therefore, the user who uses the utility model can conduct accurate sound source positioning, which brings convenience to the user.
Description
The utility model relates to a kind of hearing aids, relates in particular to a kind of hearing aids that can judge the sound bearing.
Traditional hearing aids comprises the microphone that picks up voice signal, the audio frequency amplifier that amplifies the microphone output signal and the earphone of restoring acoustical signal, and described microphone device is on the housing of placing audio frequency amplifier, and described hearing aids is a monophony.Because people's auditory localization utilizes binaural effect existing, thereby uses traditional hearing aids, weak hearer can't judge the orientation of sound, makes troubles to the user.
The purpose of this utility model is to provide a kind of hearing aids that can judge the sound bearing.
Hearing aids of the present utility model, utilize stereosonic principle, it comprises the microphone that picks up external sound, amplify the audio frequency amplifier and the earphone of the signal that microphone obtains, signal by audio frequency amplifier output promotes the earphone sounding, described microphone is divided into two microphones of left and right sound channels, described earphone also is divided into two earphones of left and right acoustic channels corresponding to microphone, and described L channel microphone is positioned at L channel microphone one side, and the R channel microphone is positioned at R channel earphone one side; Described amplifier is the dual-channel audio amplifier.
Because hearing aids of the present utility model has two microphones and earphone, has simulated people's binaural effect, thereby has had certain orientation effect, the user uses this hearing aids can judge the orientation of sound.
Fig. 1 is an embodiment of the present utility model;
Fig. 2 is the another kind of form of Fig. 1;
Fig. 3 is another embodiment of the present utility model.
Describe the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 shows an embodiment of the present utility model.As shown in Figure 1, hearing aids of the present utility model comprises headphone 1, L channel microphone 2a, R channel microphone 2b and audio frequency amplifier 3.Headphone is made up of L channel earphone 1a, R channel earphone 1b and head hoop 12, left and right acoustic channels earphone 1a, 1b lay respectively at the two ends of head hoop 12, L channel microphone 2a is positioned at head hoop 12 1 sides of device L channel earphone 1a, and R channel microphone 2b is positioned at head hoop 12 1 sides of device R channel earphone 1b.Described audio frequency amplifier 3 is a stereo amplifier, the voice signal that L channel microphone 2a picks up is after amplifier 3 L channels amplify, reset by L channel earphone 1a, the voice signal that R channel microphone 2b picks up is reset by R channel earphone 1b after amplifier 3 R channels amplify.
As mentioned above, because this hearing aids has two microphones and earphone, and two microphones lay respectively near the left and right ear of people when using, and have therefore produced binaural effect, make the user can judge the orientation of sound.
As shown in Figure 2, for headphone, left and right acoustic channels microphone 2a, 2b also can be installed on respectively in left and right sound channels earphone 1a, the 1b, and both make one.Like this, during use, two microphones are more near people's ears, the auditory localization best results.
Fig. 3 shows another embodiment of the present utility model.As shown in Figure 3, in the present embodiment, earphone adopts stereo micro earpieces 4, and left and right acoustic channels earphone 1a, the 1b of micro earpieces 4 directly fill in people's ear, this micro earpieces also comprises earphone handle 4a and 4b, and left and right acoustic channels microphone 2a, 2b place respectively in earphone handle 4a, the 4b.The signal processing method of this embodiment is identical with the embodiment of Fig. 1, no longer repeats at this.
Claims (3)
1, a kind of hearing aids that can judge the sound bearing, comprise the microphone that picks up external sound, amplify the audio frequency amplifier and the earphone of the signal that microphone obtains, signal by audio frequency amplifier output promotes the earphone sounding, it is characterized in that described microphone is divided into two microphones of left and right sound channels, described earphone also is divided into the left and right sound channels earphone corresponding to microphone, described L channel microphone is positioned at L channel earphone one side, and the R channel microphone is positioned at R channel earphone one side; Described audio frequency amplifier is the dual-channel audio amplifier.
2, hearing aids as claimed in claim 1 is characterized in that described earphone is a headphone, and the left and right sound channels earphone is connected by head hoop, and described left and right sound channels microphone device is on head hoop.
