[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0031] Example 1: See Figures 1 to 4 As shown, a hearing self-test and hearing aid effect simulator comprises a base 1 and a model 2 arranged on the base 1, wherein two simulated ears 3 are symmetrically arranged on both sides of the model 2 for easy insertion of the hearing aid;

[0032] A main control board 4 is disposed in the base 1, and a control button 17 is disposed on the base 1 and is electrically connected to the main control board 4;

[0033] Each of the artificial ears 3 is provided with a receiver (not shown in the figure) which is electrically connected to the main control board 4;

[0034] The base 1 is provided with an earphone jack 5 which is electrically connected to the main control board 4;

[0035] There is also an earphone 6, which is connected to the earphone jack 5 via an earphone cable;

[0036] A support plate 7 is detachably mounted on the front side of the base 1, and a tablet computer 8 electrically connected to the main control board 4 is detachably placed on the support plate 7, and an angle of 90° to 135° is formed between the top surface of the support plate 7 and the front end surface of the base 1;

[0037] At least one slot 9 is provided on the front end surface of the base 1, and a limiting member 10 matching the slot 9 is provided on the rear end of the support plate 7. The limiting member 10 passes through the slot 9 and is inserted into the base 1, and the front end surface of the limiting member 10 abuts against the front end inner wall of the base 1, and the bottom surface of the limiting member 10 abuts against the bottom surface of the slot 9.

[0038] In this embodiment, in actual use, there are two ways of use, the first one is hearing self-test, the operator will install the support plate and the base, when installing, insert the limiter into the slot, hook the inner end of the base through the limiter, so as to achieve the installation of the support plate, and then put the tablet computer on the support plate, the tablet computer can be electrically connected to the main control board through a line or a wireless network, the tablet computer is pre-installed with a self-test software, and the self-test software has different audio. After the patient who needs a hearing aid or the patient's family puts on the earphone, the audio in the self-test software is released through the tablet computer (the volume of the audio is directly controlled by the tablet computer), and the patient or the patient's family listens to the audio, wherein the audio can be different audio or the sound of different simulated scenes. If the patient is auditioning, the operator will make a preliminary diagnosis to diagnose the patient's hearing condition. If it is a family member, it is up to the family member to judge. Of course, the patient can also wear a hearing aid and then put on headphones for testing (hearing aids with different configurations can be worn for separate tests). This method is convenient for patients or their families to switch scenes and compare the effects during the process of selecting hearing aids (if the sound effect in the environment that the user often uses is A, and the sound effect in the environment that the user does not often use is B, then the selector can know whether the hearing aid is insufficient or otherwise, and whether it is necessary to increase or adjust the configuration to facilitate selection).

[0039] The second method: hearing aid audition. Two hearing aids are installed on two simulated ears respectively. The patient or the patient's family puts on headphones and listens to the external sounds directly through the hearing aids (the external sounds can be sounds in a normal environment, or some sounds released by other devices). The volume data is transmitted to the main control board through the radio, and the volume is adjusted through the control button so that the headphones can audition the external sounds. Different hearing aids can be installed each time, so that the patient or the patient's family can choose hearing aids with different configurations through audition, which is convenient for the selection of hearing aids (if the patient cannot hear clearly through the headphones directly, the patient's family can also audition, judge, choose, or use it as a reference). At the same time, when fitting the hearing aids in the future, the convenience of fitting is improved because the patient's needs and hearing conditions are understood in advance.

[0040] The receiver is a microphone, which is connected to the main control board via a line. An audio interface chip and an audio power amplifier are arranged on the main control board (the main control board is the main control circuit board). After the sound of the hearing aid received by the microphone is converted by the audio interface chip, the volume received by the microphone is adjusted by the audio power amplifier, and the sound is released through the earphone.

[0041] In this embodiment, the model is a head mold that simulates a human head, and artificial ears are installed on both sides of the model. The distance between the two sides is the distance between the two ears of a normal person (models with different distances between the two ears can be made for people of different types and age groups). A microphone is installed in the artificial ear to receive the sound of the hearing aid.

[0042] Among them, a cavity 11 is provided in the base 1, the main control board 4 is arranged in the cavity 11, the rear end of the slot 9 is connected to the cavity 11, the limit member 10 passes through the slot 9 and is inserted into the cavity 11, and the front end face of the limit member 10 is against the front end face of the cavity 11.

[0043] See also Figure 3 , 4 As shown, the stopper 10 includes an extension plate 13 and an insert plate 14, the front end of the extension plate 13 is connected to the rear end surface of the support plate 7, the bottom of the insert plate 14 is connected to the rear end of the extension plate 13, and the insert plate 14 and the extension plate 13 form an angle of 90° to 135°;

[0044] The front end surface of the plug plate 14 abuts against the front end inner wall of the cavity 11, and the bottom surface of the extension plate 13 abuts against the bottom surface of the slot 9. The extension plate 13 is arranged parallel to the support plate 7, and preferably, the top surface and bottom surface of the extension plate are respectively arranged flush with the top surface and bottom surface of the support plate.

[0045] The height of the through slot is greater than the thickness of the plug plate, so that when the support plate is installed, the plug plate can be smoothly inserted into the cavity through the through slot.

[0046] In this embodiment, when the support plate is installed, the support plate is first tilted so that the support plate tilts downward from the front to the back so that the end of the plug plate faces the slot, and then the plug plate is inserted into the cavity through the slot. In this process, the support plate is flipped at the same time so that the front end of the support plate rotates downward. After the plug plate is fully inserted into the cavity, the extension plate is also inserted into the slot. When the support plate continues to flip, the front end surface of the plug plate is against the front end surface of the cavity. At this time, the extension plate is also against the bottom surface of the slot, and the support plate is tilted downward from the back to the front. Preferably, the top surface of the support plate is at an angle of 15° with the front end surface of the base at this time. At this time, the support plate is inserted into the through slot through the limiting piece to hook the base, so that the limiting of the support plate is achieved, and then the tablet computer is placed on the support plate. When the tablet computer is not needed, the tablet computer is directly taken away, and the front end of the support plate is rotated upward, and the support plate is pulled forward at the same time so that the support plate is separated from the slot, and the disassembly of the support plate and the base is completed.

[0047] Among them, since there is a certain inclination angle between the front end surface of the support plate and the base, after the tablet computer is placed on the support plate, in order to prevent the tablet computer from falling from the support plate, at least one blocking plate 15 is provided on the front side of the top of the support plate 7, preferably two blocking plates 15 are provided at intervals, and the tablet computer is placed on the top surface of the support plate between the blocking plate and the limiting member. The blocking plate is arranged perpendicular to the top surface of the support plate. In this way, when the tablet computer is moved forward along the top surface of the support plate, it will be blocked by the blocking plate to prevent the tablet computer from falling, thereby ensuring the stability and safety of the tablet computer during use and preventing the tablet computer from falling and being damaged.

[0048] See also Figure 3 , 4 As shown, at least two slots 9 are arranged at intervals on the front end surface of the base 1, and each of the stoppers 10 passes through one of the slots 9 and is inserted into the base 1. Preferably, in this embodiment, there are two slots and two stoppers, which ensures stability and safety after assembly and reduces costs. Only two through slots need to be opened on the base to ensure the strength of the base and prevent deformation of the base.

[0049] See also Figure 1 , 2 As shown, the control button 17 is arranged on the front end surface of the base 1, and the control button 17 is arranged above the support plate 7;

[0050] The control buttons 17 include a volume control button 18 , a power switch 19 , and a mode selection button 12 , which are electrically connected to the main control board 4 .

[0051] The power switch is used to control the power on or off of the main control board, so that the main control board can work or stop working. The volume control button is used to control the volume of the sound emitted by the earphone during audiometry. The mode selection button has two positions, one is the hearing aid audition mode, and the other is the hearing self-test mode, which is used to switch the working mode.

[0052] The base 1 is provided with a socket 16 electrically connected to the main control board 4 , and the tablet computer 8 is plugged and connected to the socket 16 via a connecting wire, so as to electrically connect the tablet computer 8 to the main control board 4 .

[0053] The tablet computer and the main control board are directly connected through the audio cable, so that the sound played by the tablet computer is directly fed back to the earphone through the base, so that the earphone can be directly plugged into the base without frequent removal. At the same time, multiple earphone jacks can be set on the base, and each earphone jack can be connected to a headphone, so that multiple people can perform audition and self-test at the same time, which is efficient and convenient.

[0054] Among them, the jack can also be used as a headphone jack for connecting headphones to the base. The tablet computer can also be directly connected to the headphone jack through an audio cable. Of course, the tablet computer can also be connected to the main control board via Bluetooth or other wireless methods (a wireless connection module is set on the main control board). Of course, the headphones can also be connected to the main control board wirelessly, depending on the actual situation. Preferably, a wired connection is used to prevent the loss of the headphones as much as possible.
