DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly defined.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0027] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0028] In the description of this application, it should be understood that the terms "inside", "outside", "upper", "bottom", "front", "back" and the like indicate directions or positional relationships (if any) based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0029] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0030] See also Figure 1 In the first aspect, the embodiment of the present application provides a hearing aid. The hearing aid includes an earphone 2 and a hearing aid host 1, and the earphone 2 is communicatively connected to the hearing aid host 1. The hearing aid host 1 is used to receive an external sound source and amplify the external sound source, and the earphone 2 is used to receive the amplified external sound source and introduce it into the ear canal to make the human voice clearer, so as to help people with moderate hearing loss improve their hearing and thus improve their speech communication ability.

[0031] Second, see Figure 2 , Figure 7 and Figure 8 The embodiment of the present application further provides a hearing aid host 1. The hearing aid host 1 includes a housing 100 and a circuit board 200 disposed in the housing 100, the circuit board 200 has a first surface 210 and a second surface 220 disposed opposite to each other, the first surface 210 and the second surface 220 are each provided with at least one microphone, at least one of the microphones is a digital microphone 300; the housing 100 is provided with through holes corresponding to the positions of the microphones.

[0032] The hearing aid host 1 has a front side and a back side. When in use, the front side of the hearing aid host 1 faces away from the human body, that is, faces the audience, and the back side of the hearing aid host 1 faces the human body. The first side 210 of the circuit board 200 faces the front side of the hearing aid host 1, and the second side 220 of the circuit board 200 faces the back side of the hearing aid host 1. It can be understood that in other embodiments of the present application, the first side 210 of the circuit board 200 can also face the back side of the hearing aid host 1, and the second side 220 of the circuit board 200 can also face the front side of the hearing aid host 1.

[0033] The microphones on the circuit board 200 are used to pick up external sound sources through the through holes. For example, the microphone on the first side 210 of the circuit board 200 is used to pick up the sound source of the audience, and the microphone on the second side 220 of the circuit board 200 is used to pick up the sound source of the user.

[0034] The digital microphone 300 refers to a microphone that can convert traditional analog audio signals into digital signals for processing and transmission, and has a high anti-interference capability.

[0035] The hearing aid host 1 in the embodiment of the present application can fully receive external sound sources from all directions by providing at least one microphone on the first surface 210 and the second surface 220 of the circuit board 200. At the same time, by setting at least one of the microphones as a digital microphone 300, when in use, the side with the digital microphone 300 can be directed toward the user. Since the digital microphone 300 has a strong anti-interference ability, the sound source and howling emitted by the user can be processed and the noise can be filtered out, thereby improving the clarity of the sound source obtained by the hearing aid host 1, thereby ensuring that a sound source with better clarity can be received, reducing howling, improving the user experience, and also reducing the user's use.

[0036] In one embodiment, see Figure 8 , the microphone on the first side 210 is a digital microphone 300, and the microphone on the second side 220 is an analog microphone 400. When in use, the first side 210 can be turned toward the user, and the second side 220 can be turned away from the user, then the digital microphone 300 is mainly used to pick up the user's sound source, and the analog microphone 400 is mainly used to pick up the audience's sound source. Since the user's own speech will also be picked up and amplified by the hearing aid host 1 during use, the sound of one's own speech will become louder, and howling is likely to occur. Therefore, the hearing aid host 1 mainly needs to process the user's sound source. It can be understood that in other embodiments of the present application, the microphones on the first side 210 and the second side 220 of the circuit board 200 can also be set to digital microphones 300, which is not the only limitation here.

[0037] In one embodiment, see Figure 8The second surface 220 is provided with two analog microphones 400 arranged at intervals. The source of the sound is determined based on the time difference and intensity difference when the same sound is picked up by two analog microphones 400 at different positions. Then, by artificially increasing the delay of a certain analog microphone 400 or the opening of the analog microphone 400, two sounds with the same time and opposite directions are generated at the same time, achieving the effect of canceling each other out. Due to the physical space and mechanical resistance between the openings of the two analog microphones 400, the sound coming from the front may not be attenuated. It can be understood that in other embodiments of the present application, when the space inside the hearing aid host 1 is large enough and without considering the cost, more than two analog microphones 400 may be provided, and this is not the only limitation here.

[0038] In one embodiment, see Figure 8 , the digital microphone 300 and the analog microphone 400 are arranged at intervals along the first direction X, and the two analog microphones 400 are arranged at intervals along the second direction Y, and the first direction X and the second direction Y form an angle with each other. In addition, the first surface 210 and the second surface 220 of the circuit board 200 are distributed along the third direction Z, and the third direction Z is perpendicular to the first direction X and the second direction Y respectively.

[0039] In this embodiment, the first direction X is perpendicular to the second direction Y. It is understandable that in other embodiments of the present application, the first direction X and the second direction Y may also be arranged at an angle to each other, such as an angle of 60 degrees, 70 degrees, 80 degrees or 85 degrees, which is not limited here.

[0040] In this embodiment, the three microphones are distributed in a triangle so that the three microphones pick up the time difference and intensity difference of the same sound to determine the source of the sound, thereby improving the accuracy of sound source determination, and then the circuit board 200 can perform different processing according to different sound sources, so that the user can obtain an effective sound source and improve the communication effect.

[0041] Specifically, when in use, the digital microphone 300 can be placed toward the user's mouth, and the two analog microphones 400 can be placed toward the audience, to ensure that each microphone can pick up a sound source in a targeted manner.

[0042] In one embodiment, see Figure 2 and Figure 5, a second through hole 111 and two first through holes 131 are provided on the housing 100. The housing 100 has a front and a back side arranged opposite to each other, the digital microphone 300 is arranged toward the back side of the housing 100, and the second through hole 111 is arranged on the side of the housing 100, the first sound pickup hole of the digital microphone 300 is arranged opposite to the second through hole 111, and when in use, the second through hole 111 is arranged upward. The two analog microphones 400 are arranged toward the front side of the housing 100, the two first through holes 131 are arranged at intervals on the front side of the housing 100, and the second sound pickup holes of the two analog microphones 400 are arranged opposite to the two first through holes 131.

[0043] In one embodiment, see Figure 7 and Figure 8 The circuit board 200 is also provided with an indicator light 500 for power-on prompting. The indicator light 500 is electrically connected to the circuit board 200. The housing 100 is provided with a light guide column 600 at a position corresponding to the indicator light 500. The light emitted by the indicator light 500 can be guided outwards through the light guide column 600. In addition, please refer to Figure 3 A start button is also provided on the circuit board 200, and a start button 700 is installed at a position corresponding to the start button of the housing 100. Pressing the start button 700 can drive the start button to turn on the hearing aid host 1. When the hearing aid host 1 is turned on, the indicator light 500 will light up to remind the user.

[0044] In one embodiment, see Figure 5 and Figure 8 , two indicator lights 500 are provided on the circuit board 200, two light guide columns 600 are provided corresponding to the two indicator lights 500, and two light guide holes 112 are provided at the positions of the shell 100 corresponding to the two light guide columns 600; two first through holes 131 are provided at the positions of the shell 100 corresponding to the two analog microphones 400, and the two first through holes 131 and the two light guide holes 112 are symmetrically distributed along the first direction X. In this embodiment, by arranging the two first through holes 131 and the two light guide columns 600 symmetrically along the first direction X, the front of the hearing aid host 1 is made symmetrical and beautiful, thereby improving the user experience. It can be understood that in other embodiments of the present application, the number of indicator lights 500 can also be one, three, or more than three, and the number of light guide columns 600 and light guide holes 112 will also change with the number of indicator lights 500.

[0045] In one embodiment, see Figure 5 The two light guide holes 112 and the two first through holes 131 extend from the edge of the housing 100 toward the center, that is, the four holes all point to the center. In addition, a decorative piece 1300 is installed at the center of the front of the housing 100 to improve the aesthetics of the entire hearing aid host 1.

[0046] In one embodiment, see Figures 1 to 7 The housing 100 includes a front housing 110, a middle housing 120 and a lower housing 130. The middle housing 120 and the lower housing 130 are connected by snaps and enclosed to form an installation cavity. The circuit board 200 is installed in the installation cavity. The circuit board 200 is fixed to the lower housing 130 by positioning columns and screwed. The digital microphone 300, two analog microphones 400, two indicator lights 500 and a start button are all installed on the circuit board 200 and electrically connected to the circuit board 200. The two light guides 600 are fixed to the middle shell 120 by hot melting, and the middle shell 120 is also provided with two first protective covers 900, which are respectively mounted on the two analog microphones 400 and fixed by gluing. The face shell 110 is mounted on the outside of the middle shell 120 and connected to the lower shell 130. The two light guide holes 112 and the two first through holes 131 are formed on the face shell 110. The outer side of the middle shell 120 corresponds to the position of the two light guide holes 112 and is fixed with two first dustproof nets 1100 by adhesive, and the outer side of the middle shell 120 corresponds to the position of the two first through holes 131 and is fixed with two second dustproof nets 1200 by adhesive. The decorative part 1300 is fixed to the middle shell 120 by buckles, and the face shell 110 is fixed to the middle shell 120 by gluing.

[0047] See also Figure 7 The second surface 220 of the circuit board 200 is also provided with a battery 1400, which is electrically connected to the circuit board 200 and is attached to the lower shell 130 via adhesive. The circuit board 200 is also provided with a socket 1500, which is used to charge the battery 1400. The circuit board 200 is also provided with two volume keys for volume adjustment and a mode key for mode adjustment. A charging port is provided at a position of the lower shell 130 corresponding to the socket 1500, a volume button 800 is provided at a position of the lower shell 130 corresponding to the two volume keys, a mode button 1900 is provided at a position of the lower shell 130 corresponding to the mode key, a second through hole 111 is provided at a position of the lower shell 130 corresponding to the digital microphone 300, and the second through hole 111 and the charging port are both located on one side of the lower shell 130 along the second direction Y, one volume button 800 and a start button 700 are provided on one side of the lower shell 130 along the first direction X, and another volume button 800 and a mode button 1900 are provided on the other side of the lower shell 130 along the first direction X. The arrangement of the two sets of volume buttons 800 facilitates user operation. In addition, a second protective cover 1000 is also provided at a position of the lower shell 130 corresponding to the digital microphone 300.

[0048] In one embodiment, see Figures 1 to 4The outer side of the lower shell 130 is also provided with a back clip 1600, and the back clip 1600 is used to clamp the hearing aid host 1 on the user's clothes. Specifically, a rotating shaft 1700 is installed on the lower shell 130, and a torsion spring 1800 is provided on the rotating shaft 1700. The back clip 1600 is rotatably arranged on the rotating shaft 1700, and is connected to the torsion spring 1800 by the back clip 1600. The rotation driving force of the torsion spring 1800 allows the back clip 1600 to be clamped on the clothes.

[0049] In one embodiment, see Figure 1 The earphone 2 is an in-ear earphone, and the earphone 2 is connected to an earphone cable 3, and the earphone cable 3 is connected to the hearing aid host 1. A back clip 1600 is provided on the back of the hearing aid host 1. When in use, the earphone 2 can be inserted into the ear canal, and the hearing aid host 1 can be clamped on the user's clothes through the back clip 1600. In this embodiment, the earphone 2 and the hearing aid host 1 are connected through the earphone cable 3. Since the earphone cable 3 between the earphone 2 and the hearing aid host 1 is long enough, the hearing aid host 1 can be installed at a position far away from the earphone 2, thereby reducing the ear load and reducing the impact of the hearing aid host 1 on the ear. In addition, the in-ear earphone 2 can isolate part of the external sound through the earmuffs so that the sound does not overflow, thereby improving the effect of the earphone 2 in introducing the sound source.

[0050] In one embodiment, see Figure 1 and Figure 3 The earphone cable 3 is provided with a plug 31, and the hearing aid host 1 is provided with a socket 1500, and the plug 31 is electrically plugged into the socket 1500. When in use, the plug 31 can be inserted into the socket 1500, thereby forming a mechanical and electrical connection between the earphone 2 and the hearing aid host 1; when not in use, the plug 31 can be separated from the socket 1500, and the hearing aid can also be charged through the socket 1500.

[0051] In one embodiment, see Figure 1 A line dividing buckle 4 is provided on the headphone cable 3, wherein the setting of the line dividing buckle 4 is conducive to the management of the headphone cable 3, and can also reduce the possibility of losing the headphone 2 or the hearing aid host 1.

[0052] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
