In another embodiment, the first side 1101 may include a first side, and the second side 1102 may also include a second side, a third side, and a fourth side, the first side being provided with one first touch sensor 120, and the second side, the third side, and the fourth side being provided with at least one second touch sensor 130. If the first touch sensor 120 on the first side detects the human skin touch signal, the second touch sensors 130 on the second side, the third side and the fourth side do not detect the human skin touch signal, which indicates that the hearing aid is worn in place. If the first touch sensor 120 on the first side detects a human skin touch signal, the second touch sensors 130 on the second side, the third side and the fourth side detect a human skin touch signal, indicating that the hearing aid is in the hand of the user.
Hearing aids can be classified according to the wearing position as in-ear hearing aids (hearing aids worn in the ear), behind-the-ear hearing aids (hearing aids worn behind the ear), or head-mounted hearing aids (hearing aids worn on the head).
In one embodiment, the hearing aid is an in-ear or behind-the-ear hearing aid that may be worn by a user at the ear to transmit sound to the user's brain through the ear canal, and the first face 1101 of the hearing aid housing 110 is the side of the hearing aid that contacts the skin of the ear when the hearing aid is worn by the user at the ear. When the hearing aid is worn at the ear, the first touch sensor 120 is touched by the skin at or around the ear to generate a human skin touch signal. For example, as shown in fig. 1, an in-ear hearing aid has a housing 110 including a first shell and a second shell, the bottom of the first shell communicating with the top of the second shell; the loudspeaker is arranged in the first shell, and the first shell is used for extending into the auditory canal so that the loudspeaker transmits sound through the auditory canal; the second shell comprises four sides and a bottom, the four sides are respectively used as a first side, a second side, a third side and a fourth side of the hearing aid shell 110 for placing the touch sensor, the first side and the second side are both flat surfaces, the third side and the fourth side are curved surfaces, the first side and the second side are opposite, the third side and the fourth side are opposite, and the first side and the second side are respectively connected smoothly through the third side and the fourth side.
In another embodiment, the hearing aid may be a head-mounted hearing aid, or the hearing aid may be worn on the head by the user to transmit sound to the user's brain through the skull bone, and the first face 1101 of the hearing aid housing 110 is the face of the hearing aid that contacts the skin of the head when the hearing aid is worn on the head by the user. When the hearing aid is worn on the head, the first touch sensor 120 is touched by the skin of the head to generate a human skin touch signal. In general, the first side of the head-mounted hearing aid contacts the skin of the head as the first side 1101, the first touch sensor 120 is obviously disposed on the side contacting the skin of the head, and the second touch sensor 130 may be disposed on any side not contacting the skin of the head, or on both sides not contacting the skin of the head.
The main control unit 140 may sound/mute the speaker by powering on/off. In one embodiment, referring to fig. 3, the hearing aid comprises a power source 150, the power source 150 being connected to a speaker of the hearing aid; the power supply 150 is also connected to the main control unit 140; the main control unit 140 is configured to enable the power supply 150 to supply power to the speaker to make the speaker generate sound when the first touch sensor 120 detects a human skin touch signal and the second touch sensor 130 does not detect a human skin touch signal. The main control unit 140 is further configured to turn off the power supply when the second touch sensor 130 detects a human skin touch signal, so that the speaker cannot be powered to stop working, and thus does not generate sound. The power supply 150, which may be a rechargeable power supply, is disposed within the housing 110.
In one embodiment, referring to fig. 4-5, a hearing aid comprises: at least one infrared sensor 160 disposed on the first face 1101; the infrared sensor 160 is connected to the main control unit 140 for sensing the approach and the departure of the skin at the wearing position. The infrared sensor 160 has a pair of infrared signal transmitting and receiving diodes for detecting a distance. The main control unit 140 is configured to make the speaker generate sound when the infrared sensor 160 senses that the skin is closer to the wearing position, and finally when the first touch sensor 120 detects a human skin touch signal and the second touch sensor 130 does not detect a human skin touch signal, and is configured to make the speaker generate sound when the infrared sensor 160 senses that the skin is farther from the wearing position, and finally when the second touch sensor 130 detects a human skin touch signal, the speaker does not generate sound.
Before the user holds the hearing aid in the hand and prepares to put on the hearing aid, the first touch sensor 120 on the first side 1101 and the second touch sensor 130 on the second side 1102 both detect the human skin touch signal, the distance between the infrared sensor 160 on the first side 1101 and the user is closer, after the hearing aid is successfully worn, the user looses his hand, and finally only the first side 1101 of the hearing aid contacts the skin, that is, the first touch sensor 120 on the first side 1101 detects the human skin touch signal. After removing the hearing aid and holding the hearing aid, the user will detect human skin touch signals from both the first touch sensor 120 on the first side 1101 and the second touch sensor 130 on the second side 1102, and the infrared sensor 160 on the first side 1101 will detect the user at a greater and greater distance since the first side 1101 is away from the skin at the wearing position.
In the hearing aid, when the hearing aid is worn by a user, the first surface 1101 contacting the skin at the wearing position is provided with the first touch sensor 120, and when the hearing aid is worn by the user, the second surface 1102 not contacting the skin at the wearing position is provided with the second touch sensor 130, so that when the first touch sensor 120 on the first surface 1101 is touched by a human body, the first touch sensor 120 detects a human body skin touch signal, the second touch sensor 130 on the second surface 1102 is not touched by the human body, and the second touch sensor 130 does not detect the human body skin touch signal, which indicates that the hearing aid is worn in place, the speaker can sound; if the second touch sensors 130 detect a touch signal of the skin of the human body, indicating that the hearing aid is likely to be in the hand of the user, the speaker is disabled, thereby preventing the speaker from howling, for example, the speaker from making a conch sound, and saving power for the hearing device.
The present application further provides a howling prevention method for a hearing device, which takes the howling prevention method for a hearing aid as an example, and fig. 6 is a flowchart of the howling prevention method for a hearing aid in one embodiment. The howling prevention method in the present embodiment is described by taking the hearing aid operating in fig. 2 as an example, and may specifically operate in the main control unit 140 in fig. 2. As shown in fig. 3, the anti-howling method for a hearing aid comprises steps 602 to 604.
In step 602, the first touch sensor 120 is used to detect a human skin touch signal, and the second touch sensor 130 is used to detect a human skin touch signal.
In step 604, if the first human skin information is acquired from the first touch sensor 120 and it is determined that the second human skin information is not acquired from the second touch sensor 130, it is determined that the hearing aid is worn in place by the user, and the hearing aid is controlled to work to sound a speaker. If the second human skin information is acquired from the second touch sensor 130, it is determined that the hearing aid is in the hand of the user, and the speaker is controlled not to sound, so as to prevent the hearing aid from howling.
The first human skin information is the human skin information obtained by the first touch sensor 120, and since the first touch sensor 120 is worn in a position where the hearing aid is worn to contact the skin at the wearing position, such as the skin of a joint contact or the skin of an ear, the first human skin information is the skin information at the wearing position if the hearing aid is worn in a position where the hearing aid is worn, and the first human skin information is the skin information of a human hand if the hearing aid is in the hand. The second human skin information is human skin information obtained by the second touch sensor 130, and is skin information of the human hand because the second touch sensor 130 is provided at a position where the hearing aid is not in contact with the skin at the wearing position.
In this embodiment, if the first touch sensor 120 senses a touch on the skin of a human body and the second touch sensor 130 does not sense a touch on the skin of a human body, which indicates that the hearing aid is worn on the site, the speaker of the hearing aid is controlled to emit sound.
Sometimes, the hearing aid only occasionally touches the skin at the wearing position, and therefore it is possible to determine whether the hearing aid is worn in place in combination with the time. In one embodiment, if the first human skin information is continuously acquired from the first touch sensor 120 and the time of continuously acquiring the first human skin information exceeds a preset time and it is confirmed that the second human skin information is not acquired from the second touch sensor 130 within the time of continuously acquiring the first human skin information, it is determined that the hearing aid has been worn in place by the user.
In particular, the housing 110 of the hearing device comprises a first side, a second side, a third side and a fourth side, the first and second sides being opposite, the third and fourth sides being opposite, the first and second sides being smoothly connected by the third and fourth sides, respectively; wherein the first side 1101 comprises a first side provided with at least one first touch sensor 120 and the second side 1102 comprises a second side provided with at least one second touch sensor 130.
In one embodiment, the first side 1101 includes a first side configured with at least one first touch sensor 120, the second side 1102 includes a second side including at least one second touch sensor 130; if the second human skin information is acquired from the second touch sensor 130, it is determined that the hearing aid is held in the hand of the user and the speaker of the hearing aid is not sounded if the second human skin information is acquired from the second touch sensor 130 and the first human skin information is acquired from the first touch sensor 120.
In this embodiment, the first touch sensor 120 on the first side detects a touch on the skin of a human body, and the second touch sensor 130 also detects a touch on the skin of a human body, which indicates that the hearing aid may be held in the hand of the user instead of being worn at a corresponding position of the user, and then the speaker of the hearing aid is not used to generate sound.
In another embodiment, the first face 1101 includes a first side, the first side being configured with at least one first touch sensor 120; the number of the second touch sensors 130 is at least two, the second surface 1102 includes a third side surface and a fourth side surface, and at least one second touch sensor 130 is disposed on each of the third side surface and the fourth side surface. The step of detecting the human skin touch signal using the second touch sensor 130 is to detect the human skin touch signal using the second touch sensors 130 disposed at both sides; if the second human skin information is acquired from the second touch sensor 130, the step of determining that the hearing aid is in the hand of the user is to determine that the user is pinching both side surfaces of the hearing aid housing 110 if the second human skin information is acquired from both side second touch sensors 130.
In this embodiment, if only the second touch sensor 130 senses a touch signal of the skin of the human body, and the first touch sensor 120 does not sense a touch signal of the skin of the human body, it indicates that the hearing aid is worn by fingers on both left and right sides of the hearing aid, and is also worn by fingers on both sides of the housing 110 after being taken out from the wearing position, which indicates that the hearing aid is not worn on the position, and it is necessary to prohibit a speaker of the hearing aid from generating sound to avoid howling.
In other embodiments, when the hearing aid is worn, for example, in the case of a head-mounted hearing aid, the first side of the hearing aid housing 110 is in contact with the skin at the wearing position, and none of the other sides are in contact with the skin at the wearing position, then the first side 1101 may comprise the first side, and the second side 1102 may also comprise the second side, the third side, and the fourth side, each of which is provided with at least one second touch sensor 130. If the first human skin information is acquired from the first touch sensor 120 on the first side, the second human skin information is not acquired from the second touch sensors 130 on the second side, the third side and the fourth side, which indicates that the hearing aid is worn in place. If the first human skin information is acquired from the first touch sensor 120 on the first side, the second human skin information is acquired from the second touch sensor 130 on the second side, the third side and the fourth side, which indicates that the hearing aid is held in the hand of the user.
Sometimes, the user wears the hearing aid halfway to adjust the position of the hearing aid, and both the first touch sensor 120 and the second touch sensor 130 sense the touch on the skin of the human body. It is thus possible to determine whether the hearing aid is worn in place in connection with time. In one embodiment, if the second human skin information is continuously acquired from the second touch sensor 130 and the time for continuously acquiring the second human skin information exceeds a preset time, it is determined that the hearing aid is in the hand of the user.
In one of the embodiments, the method further comprises the step of detecting the distance between the hearing aid and the user;
if the first human skin information is acquired from the first touch sensor 120 and it is confirmed that the second human skin information is not acquired from the second touch sensor 130, the step of determining that the hearing aid is worn in place by the user is: if the distance between the hearing aid and the user is detected to be smaller and smaller, and finally smaller than the first preset distance threshold value, the first human skin information is acquired from the first touch sensor 120, and the second human skin information is not acquired from the second touch sensor 130, it is determined that the hearing aid is worn in place by the user.
If the second human skin information is acquired from the second touch sensor 130, the step of determining that the hearing aid is in the hand of the user, and the first touch sensor 120 and the second touch sensor 130 are as follows: if it is detected that the distance between the hearing aid and the user is larger and larger than the second preset distance threshold, and finally, the second human skin information is acquired from the first touch sensor 120 and also from the second touch sensor 130, it is determined that the hearing aid is held in the hand of the user.
In particular, the hearing aid comprises at least one infrared sensor arranged on the first face 1101; the step of detecting the distance between the hearing aid and the user is detecting the distance between the hearing aid and the user by means of an infrared sensor.
In this embodiment, when the hearing aid is worn and a user holds the hearing aid in his hand, both the first touch sensor 120 on the first side 1101 and the second touch sensor 130 on the second side 1102 detect human skin touch signals, because the first side 1101 is finally to be in contact with the skin at the wearing position, the infrared sensor on the first side 1101 detects that the user is closer and closer, and after the hearing aid is successfully worn, the user looses his hand, and finally only the first side 1101 of the hearing aid is in contact with the skin, and only the first touch sensor 120 detects the human skin touch signals. After removing the hearing aid and holding the hearing aid in the hand of the user, the first touch sensor 120 of the first side 1101 and the second touch sensor 130 of the second side 1102 both detect human skin touch signals, and the infrared sensor of the first side 1101 detects that the user is further away because the first side 1101 is away from the skin at the wearing position.
In the above hearing aid squeaking prevention method, when the hearing aid is worn by a user, the first surface 1101, which is in contact with the skin at the wearing position, is provided with the first touch sensor 120, and when the hearing aid is worn by the user, the second surface 1102, which is not in contact with the skin at the wearing position, is provided with the second touch sensor 130, so that when the first touch sensor 120 of the first surface 1101 is touched by a human body, the first touch sensor 120 detects a human body skin touch signal, the second touch sensor 130 of the second surface 1102 is not touched by the human body, and the second touch sensor 130 does not detect the human body skin touch signal, which indicates that the hearing aid is worn in place, and then the speaker can sound; if the second touch sensors 130 detect a touch signal of the skin of the human body, indicating that the hearing aid is likely to be in the hand of the user, the speaker is disabled, thereby preventing the speaker from howling, for example, the speaker from making a conch sound, and saving power for the hearing device.
