Problems solved by technology

[0005] While it is possible to use an ANC control system to record ambient noise and play it back to the user, previous attempts did not take into account the individual characteristics of the user's ear
As a result, the user does not perceive ambient sounds as accurately as he / she does without headphones

Embodiment Construction

[0032]Automatic calibration method

[0033] The method of automatic calibration ear earphone embodiment will now be described in detail.

[0034] figure 1 It shows a simplified flowchart of a method of automatic calibration ear earphone. The method may be as Figure 21 with Figure 22 Ear earphone illustrated performed, the in-ear earphone comprising a driver, a first microphone and an integrated circuit. Further details are discussed below said ear earphone. At step 102, when the in-ear earphone placed in the user's ear canal, ear earphone circuit that generates a sound signal for playback to a user. The sound signal may be generated by the integrated circuit ear headphones and the number of scans may have a duration of one second. The sound signals may be in-ear earphone drive to play, wherein the driver may be capable of any known speaker sound quality playback to the user. Further, the drive may be a dynamic (moving coil) type driver, and may have a diameter of 5mm to 8mm, the ...

Abstract

Disclosed is a method for calibrating an in-ear headphone to improve the frequency response heard by a user. The method including generating a sound signal and playing the sound signal at a driver when the in-ear headphone is placed within a user's ear canal, receiving a reflected sound signal at a first microphone, generating a frequency response based on the reflected sound signal, generating the user's ear drum response based on the frequency response, generating a second sound signal, modifying the second sound signal based on the user's ear drum response, and playing the modified second sound signal at the driver.

Description

Technical field [0001] This document generally relates to an automatic calibration method of incompetent earphone and a corresponding device. Calibrate the frequency response used to improve users. Background technique [0002] With the increased development of technologies in the sound industry, it is possible to reproduce high quality sound from smaller and more complex drives in the headset. However, due to individual features of the user's ear (such as specific dimensions and shapes in the ear canal, how many sounds are absorbed in the user's ear canal), the user will receive different frequencies at their diaphragm. In order to achieve optimization and similar frequency response for all users, the headset should be calibrated (ie, separately equalize) the headset. The headphone transfer function (HPTF) describes how sound is filtered on the path from the sound source to the tympanic membrane. By using the appropriate separate HPTF, the HPTF can be used as a filter to balance...
