Hearing aid compatibility (Hearing Aid Compatibility, HAC for short) refers to the performance of digital mobile phone compatible hearing aids. A hearing aid is a device that helps a hearing impaired user to receive external sound signals. Depending on the way of acoustic wave conduction, hearing aids today mainly include bone conduction hearing aids, air conduction hearing aids and magnetic conduction hearing aids. Bone conduction hearing aids are devices that transmit sound signals from a speaker through the bone of the head to the user's auditory nerve center. The air-conduction hearing aid is used for amplifying the sound emitted by the loudspeaker again and transmitting the sound to a user through air.
With the popularity of digital mobile phones, when a call is made using a digital mobile phone, radio waves emitted from the digital mobile phone form an electromagnetic field around an antenna, which affects the performance of a hearing aid, and when the hearing aid is disturbed by the magnetic field of the mobile phone, a user hears an offensive buzzing sound.

Detailed Description
In order to describe the technical content, the constructional features, the achieved objects and effects of the present invention in detail, the following description is made in connection with the embodiments and the accompanying drawings.
In order to cope with the requirement of hearing aid compatibility (i.e., HAC) detection on acoustic and magnetic dual indexes, the embodiment discloses a method for debugging hearing aid compatibility of a terminal device, so as to detect hearing aid compatibility of the terminal device (such as a mobile phone). To this end, in order to facilitate implementation of the commissioning mode, as shown in fig. 1, an audio system of the terminal device is first configured, i.e. the audio system comprises an audio processor 1, a first speaker 3, an inductive element 4, a first audio driver 20 and a second audio driver 21.
The audio processor 1 has two channel output ports, i.e. two independent audio channels are provided through the two channel output ports, the two channel output ports being a first channel port D1 and a second channel port D2, respectively. The audio processor 1 is connected to a first audio driver 20 via a first channel port D1, the first audio driver 20 being connected to a first speaker 3. The audio processor 1 is connected to the inductive element 4 via a second sound port D2 and a second audio driver 21. The inductive element 4 and the first loudspeaker 3 are located in the same area of the terminal device, so that both the acoustic signal and the magnetic signal can be detected from the same area of the terminal device. For the inductance component 4 in this embodiment, it emits a corresponding electromagnetic signal based on the audio signal output by the second audio driver 21, and the receiver of the hearing aid can convert the current generated according to the electromagnetic signal into sound waves for output, so that the hearing-impaired user can obtain the sound output by the terminal device.
The debugging method of the audio system configured based on the terminal equipment, as shown in fig. 3, comprises the following steps:
s1: the audio processor 1 synchronously sends out original audio data signals through a first channel port D1 and a second channel port D2 respectively;
s2: the first audio driver 20 drives the first speaker 3 to emit sound;
the second audio driver 21 drives the inductance element 4 to emit electromagnetic signals;
s3: collecting sound field signals from the output end of the first loudspeaker 3, and adjusting first output parameters of the audio processor 1 according to the sound field signals so that the sound field signals output by the audio system meet standard requirements;
and magnetic field signals are collected from the inductance element 4, and the second output parameters of the audio processor 1 are adjusted according to the magnetic field signals, so that the magnetic field signals output by the audio system meet the standard requirements.
In addition, since the magnetic field is also present in the sound field signal emitted from the output end of the first speaker 3, in order to avoid that the magnetic field in the sound field signal attenuates the magnetic field signal emitted from the inductor 4, the audio processor 1 outputs the same phase of the audio signals to the first channel port D1 and the second channel port D2, so as to ensure that the magnetic field signal emitted from the inductor 4 and the magnetic field in the sound field signal do not cancel each other, thereby respectively debugging the acoustic index and the magnetic index. Specifically, the audio processor 1 copies the original audio data signal into two identical audio data signals and synchronously transmits them to the first channel port D1 and the second channel port D2. Preferably, the first channel port D1 is used as a left channel of the audio system and the second channel port D2 is used as a right channel of the audio system, i.e. both the first speaker 3 and the inductance element 4 are used as a left channel outlet of the terminal device.
On the other hand, as shown in fig. 2, the audio system further includes a selection switch K, a second speaker 5, and a third audio driver 22, where the third audio driver 22 and the second audio driver 21 are connected in parallel to the second channel port D2 of the audio processor 1 through the selection switch K, and the third audio driver 22 is connected to the second speaker 5, and the selection switch K is used to select one of the second audio driver 21 and the third audio driver 22 to access the second channel port D2. The third audio driver 22 is turned off by turning on the second audio driver 21 by selecting the switch K when the terminal device is in the HAC detection mode or the hearing aid mode, and the second audio driver 21 is turned off by turning on the third audio driver 22 by selecting the switch K when the terminal device is in the normal use mode.
In addition, based on the configuration of the terminal device in the above embodiment, the present embodiment also discloses a system for debugging hearing-aid compatibility of the terminal device, where the debugging system includes an audio output module, an acquisition module and a debugging module.
The corresponding audio output module is configured to send out original audio data signals to the first audio driver 20 and the second audio driver 21 through the audio processor 1 through the first channel port D1 and the second channel port D2, respectively, so that the first audio driver 20 drives the first speaker 3 to send out sound, and the second audio driver 21 drives the inductance element 4 to send out electromagnetic signals.
For the acquisition module, it is used for gathering the sound field signal from the output end of the first loudspeaker 3, and gather the magnetic field signal from the inductance component 4;
for the debugging module, the debugging module is used for adjusting the first output parameter of the audio processor 1 according to the difference between the sound field signal and the standard sound field signal so that the sound field signal output by the audio system meets the standard requirement; and is used for adjusting the second output parameter of the audio processor 1 according to the difference between the magnetic field signal and the standard magnetic field signal, so that the magnetic field signal output by the audio system meets the standard requirement.
In summary, the invention discloses a method and a system for debugging hearing-aid compatibility of a terminal device, because an audio system of the terminal device is respectively connected with a first loudspeaker 3 and an inductance element 4 through two different audio channels, in the debugging process, sound field signals and magnetic field signals can be respectively obtained from the first loudspeaker 3 and the inductance element 4, and therefore, a first output parameter corresponding to a sound field and a second output parameter corresponding to a magnetic field of the audio system are adjusted, so that the terminal device meets magnetic and acoustic index requirements.
