    Abstract

    A personalized earphone for people with auditory abnormality, includes a microphone, a preamplifier, an analogue-to-digital (A/D) converter, a Bluetooth wireless circuit, a Digital Signal Processing (DSP) module, a digital-to-analogue (D/A) converter, a post-amplifier and a loudspeaker. The microphone is arranged to pick up an ambient noise and deliver information about the ambient noise to the preamplifier, the preamplifier is arranged to convert the ambient noise to a digital signal and input the digital signal to the DSP module. The DSP module is arranged to internally generate a noise-reduction signal that is converted to an original noise, and convert the noise-reduction signal to an analogue signal that is amplified by the post-amplifier and delivered to the loudspeaker. The DSP module is connected with the Bluetooth wireless circuit.

    Claims

    1. A personalized earphone for people with auditory abnormality, comprising a microphone (1), a preamplifier (2), an analogue-to-digital (A/D) converter (3), a Bluetooth wireless circuit (4), a Digital Signal Processing (DSP) module (5), a digital-to-analogue (D/A) converter (6), a post-amplifier (7) and a loudspeaker (8), wherein the microphone (1) is arranged to pick up an ambient noise and deliver information about the ambient noise to the preamplifier (2), the preamplifier (2) is arranged to convert the ambient noise to a digital signal and input the digital signal to the DSP module (5), and the DSP module (5) is arranged to internally generate a noise-reduction signal that is converted to an original noise, and convert the noise-reduction signal to an analogue signal that is amplified by the post-amplifier (7) and delivered to the loudspeaker (8), the DSP module (5) being connected with the Bluetooth wireless circuit (4).

    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0010] The accompanying drawings, as a part of the description, are used to explain embodiments of the disclosure, and not intended to limit the scope of protection. In the drawing:

    [0011] FIG. 1 is a schematic diagram showing the operation principle of a personalized earphone for people with auditory abnormality according to an embodiment of the disclosure.

    [0012] Where 1 denotes a microphone, 2 denotes a preamplifier, 3 denotes an A/D converter, 4 denotes a Bluetooth wireless circuit, 5 denotes a DSP module, 6 denotes a D/A converter, 7 denotes a post-amplifier and 8 denotes a loudspeaker.

    DETAILED DESCRIPTION

    [0013] Preferred embodiments of the disclosure will be elaborated below with reference to accompanying drawings, and it should be appreciated that preferred embodiments described below are only used to describe and explain the disclosure instead of limiting it.

    [0014] As shown in FIG. 1, a personalized earphone for people with auditory abnormality according to an embodiment of the disclosure includes a microphone 1, a preamplifier 2, an A/D converter 3, a Bluetooth wireless circuit 4, a DSP module 5, a D/A converter 6, a post-amplifier 7 and a loudspeaker 8, wherein the microphone 1 is arranged to pick up an ambient noise and deliver information about the ambient noise to the preamplifier 2, the preamplifier 2 is arranged to convert the ambient noise to a digital signal and input the digital signal to the DSP module 5, and the DSP module 5 is arranged to internally generate a noise-reduction signal that is converted to an original noise, and convert the noise-reduction signal to an analogue signal that is amplified by the post-amplifier 7 and delivered to the loudspeaker 8. The DSP module 5 is connected with the Bluetooth wireless circuit 4. The microphone 1 picks up the ambient noise and delivers the ambient noise to the preamplifier 2, which generates a waveform inverted from a waveform of the ambient noise and delivers the generated inverted waveform back to the microphone 1. The Bluetooth wireless circuit 4 is tuned with a computer or a mobile phone.

    [0015] It is to be noted that the personalized earphone for people with auditory abnormality according to embodiments of the disclosure can be adjusted, in operation, using Bluetooth technique to serve as a general heating aid. It can serve as a Bluetooth earphone to implement the hearing aid function during a phone call and for listening to music. The noise-canceling techniques used include DSP noise-canceling technique and passive noise-canceling technique for auditory frequency responses of different people and for a specific earphone mechanical structure. The sensitivity of each patent with ASD within a specific frequency range can be estimated through Bluetooth technique.

    [0016] It is to be noted that what described above are merely preferred embodiments of the disclosure and are not intended to limit the disclosure. Although the disclosure is elaborated with reference to the above embodiments, those skilled in the art may modify the technical solutions as disclosed above, or make replacements of part of technical features of the technical solutions. All modifications, replacements and improvements made within the spirit and principles of the disclosure should be included within the scope of protection of the disclosure.
