[0003] The bone conduction vibrator is connected to an audio signal source by a signal transmission member, and realizes the transmission of the audio signal to the wearer by converting the audio signal into mechanical vibration and transmitting it to the wearer. In the process of transmitting vibration to the wearer, the bone conduction vibrator needs to be in constant contact with the wearer to avoid interruption or error in the transmission process. If the contact pressure between the bone conduction vibrator and the wearer is too large, it will cause discomfort to the wearer, and if the contact pressure between the bone conduction vibrator and the wearer is too small, the effect of signal transmission will be reduced.

Similarly, similar terms such as "one" or "one" do not limit the number, but indicate the presence of at least one. Unless otherwise stated, similar terms such as "front", "rear", "lower" and / or "upper" are not intended to be limited to one location or one spatial orientation, but are merely for ease of description. In general, the terms "comprise" and "contain" are merely intended to indicate the inclusion of explicitly identified steps and elements, and these steps and elements are not an exclusive listing, and the method or apparatus may include other steps or elements.

[0030] In the embodiments of the present specification, a fixing assembly of a bone conduction vibrator is described. In some embodiments, the fixing assembly of the bone conduction vibrator may include an elastic fixing part and a fixing member, the elastic fixing part has a band-like structure, the fixing member fixes the elastic fixing part so as to surround the wearing object, thereby placing the bone conduction vibrator between the elastic fixing part and the wearing object, and the elastic fixing part presses the bone conduction vibrator against the wearing object to realize contact between the bone conduction vibrator and the wearing object, thereby ensuring that the bone conduction vibrator transmits vibration to the wearing object and outputs an audio signal (e.g., bone conduction sound wave) to the wearing object. In some embodiments, the fixing member is fixed to a first end of the elastic fixing part and removably fixed to a second end of the elastic fixing part, and the position of the fixing member removably fixed to the second end of the elastic fixing part is adjustable, so that the length of the elastic fixing part surrounding the wearing object is adjustable, and thus the pressure between the elastic fixing part and the wearing object is adjustable. For example, the fixing member is a pin buckle, the second end of the elastic fastening part has a plurality of locking holes arranged at intervals along its length, and the fixing member and the elastic fastening part are removably fixed by the engagement of the pin buckle with the locking holes. For example, the fixing member is a hook-and-loop fastener including a loop surface and a hook surface, and the fixing member and the elastic fastening part are removably fixed by adhesion between the loop surface and the hook surface. For example, the fixing member is a ring buckle, the second end of the elastic fastening part has a plurality of locking grooves arranged at intervals along its length, and the fixing member and the elastic fastening part are removably fixed by the engagement of the ring buckle with the locking grooves.

[0031] In some embodiments, the elastic fixing part may include a first position and a second position at the second end, the first position and the second position being spaced apart along the length of the elastic fixing part. When the fixing member engages with the first position of the elastic fixing part, the elastic fixing part surrounds the wearing subject and is in a natural state. When the fixing member engages with the second position, the elastic fixing part provides the bone conduction transducer with a suitable pressure acting on the wearing subject, and the pressure is within a predetermined pressure range, so that the wearing subject can receive the audio signal effectively and feel comfortable. In some embodiments, the product of the distance between the first position and the second position and the elastic modulus of the elastic fixing part is within a predetermined pressure range, and the engagement position of the fixing member and the elastic fixing part can be adjusted between the first position and the second position such that the pressure provided by the elastic fixing part to the bone conduction transducer is always within the predetermined pressure range.

[0032] In some embodiments, the fixing assembly can be used to test the bone conduction vibrator. Specifically, when testing the bone conduction vibrator, the fixing assembly fixes the bone conduction vibrator to a subject (e.g., a human body, a guinea pig, etc.), the bone conduction vibrator outputs an audio signal to the subject, and the subject detects a feedback signal generated in response to the audio signal output from the bone conduction vibrator, and the signal transmission performance of the bone conduction vibrator can be determined by the feedback signal. In some embodiments, if the strength of the detected feedback signal is equal to or greater than a predetermined signal strength, it is considered that the transmission performance of the audio signal of the bone conduction vibrator is high, and after the subject receives the audio signal, the information contained in the audio signal can be effectively obtained. In some embodiments, the pressure between the subject and the bone conduction vibrator or the fixing assembly is detected, and a set of pressures where the strength of the feedback signal is equal to or greater than a predetermined signal strength can be determined as the predetermined pressure range.

[0033] In some embodiments, the fixing assembly can be further used to wear an audio output device. Specifically, the audio output device may include a bone conduction vibrator, and during the activity of the wearer, the fixing assembly can always maintain relative fixation and / or contact between the audio output device and the head of the wearer, so that the audio signal output from the audio output device is transmitted to the wearer and sensed by the auditory nerve of the human body. In some embodiments, the fixing assembly can be further used to wear other devices (e.g., electronic devices). For example, the fixing assembly can be used to wear devices such as a wristwatch, an oximeter, a blood pressure monitor, and a pedometer.

[0034] FIG. 1 is a block diagram of a fixing assembly according to some embodiments of the present specification. As shown in FIG. 1, a fixing assembly 100 of a bone conduction vibrator may include an elastic fixing part 110 and a fixing member 120. The elastic fixing part 110 is an elastic structure made of an elastic material. The elastic fixing part 110 has tension due to its elasticity, and provides the bone conduction vibrator with a pressure acting on the wearing target, and the tension of the elastic fixing part 110 can be approximately regarded as the pressure that the bone conduction vibrator acts on the wearing target. In some embodiments, the pressure that the bone conduction vibrator acts on the wearing target can be determined by determining the tension of the elastic fixing part 110. The calculation formula for the tension of the elastic fixing part 110 (the pressure that the bone conduction vibrator acts on the wearing target) is as follows.

[0035] F = k × x (1)

[0036] Here, F is the pressure that the bone conduction vibrator exerts on the subject, k is the elastic coefficient of the elastic fixing portion 110, and x is the amount of deformation that occurs in the elastic fixing portion 110.

[0037] The elastic coefficient of the elastic fixing part 110 is related to the thickness, length, width, shape, and material of the elastic fixing part 110. In some embodiments, the elastic coefficient of the elastic fixing part 110 is adjusted by adjusting any one or more of the thickness, length, width, shape, material, etc. of the elastic fixing part 110, thereby making it possible to adjust the pressure that the bone conduction vibrator exerts on the wearing subject.

[0038] In some embodiments, the thickness of the elastic fixing part 110 may be in the range of 0.6 mm to 2 mm. In some embodiments, the thickness of the elastic fixing part 110 may be in the range of 0.7 mm to 1.5 mm. In some embodiments, the thickness of the elastic fixing part 110 may be in the range of 0.8 mm to 1.2 mm. In some embodiments, the thickness of the elastic fixing part 110 may be in the range of 0.9 mm to 1.0 mm. In some embodiments, the thickness of the elastic fixing part 110 is 0.8 mm, 1.1 mm, or 1.2 mm, etc. Preferably, the thickness of the elastic fixing part 110 may be 1.2 mm. Note that the thickness of the elastic fixing part 110 may be other thicknesses (e.g., less than 0.6 mm or more than 2 mm), and the present application does not specifically limit it.

[0039] In some embodiments, the elastic material of the elastic fixing portion 110 may include a silicone rubber material. In some embodiments, the silicone rubber material is one or more of the following: 10 degree silicone rubber 50% high tensile silicone rubber material, 20 degree silicone rubber 50% high tensile silicone rubber material, 30 degree silicone rubber 50% high tensile silicone rubber material, 10 degree silicone rubber 70% high tensile silicone rubber material, 20 degree silicone rubber 70% high tensile silicone rubber material, 30 degree silicone rubber 70% high tensile silicone rubber material, 10 degree silicone rubber 1% high tensile silicone rubber material, 20 degree silicone rubber 1% high tensile silicone rubber material, or 30 degree silicone rubber 1% high tensile silicone rubber material. Note that in other embodiments of the present application, the elastic fixing portion 110 may be made of other materials such as polycarbonate, polyamide, rubber, etc., and is not specifically limited here.

[0040] The elastic coefficients of the elastic fixing parts 110 having different elasticity (e.g., different thicknesses and / or materials) can be obtained by testing in advance, and the testing method is as follows: obtain an elastic belt having the same material, thickness, and width as the elastic fixing part 110, apply a predetermined tensile force value to the elastic belt by a tension meter to deform the elastic belt, measure the deformation amount of the elastic belt, and calculate the elastic coefficient k according to formula (1), i.e., the elastic coefficient k is equal to the predetermined tensile force value divided by the deformation amount of the elastic belt.

[0041] In some embodiments, the elastic fixing portion 110 may have a band-like structure. The elastic fixing portion 110 has first and second positions spaced apart along its length, and the first and second positions of the elastic fixing portion 110 can be engaged with the fixing member 120 to adjust the elastic fixing portion to provide the bone conduction transducer with a pressure acting on the wearing target. For example, when the elastic fixing portion 110 surrounds a specific part of the wearing target (e.g., the head) and the fixing member 120 engages with the first position of the elastic fixing portion 110, the elastic fixing portion 110 is in a natural state. Also, for example, when the fixing member 120 engages with the second position, the elastic fixing portion 110 provides the bone conduction transducer with a pressure within a predetermined pressure range acting on the wearing target. The natural state can be understood as a state in which the fixing assembly 100 can surround a specific part of the wearing target and the pressure acting on the wearing target provided by the bone conduction transducer is less than a specific pressure (e.g., 0.2 N). In some embodiments, the elastic fixing part 110 may include a belt, and the fixing member 120 may fix the belt so as to surround the wearing subject. For more information on the belt, please refer to FIG. 2, FIG. 3 and the related description. In some embodiments, the elastic fixing part 110 may include a first belt and a second belt, and the fixing member 120 may fix the first belt and the second belt so as to surround different parts of the wearing subject. For more information on the first belt and the second belt, please refer to FIG. 6 and the related description.

[0042] The fixing member 120 is configured to fix the elastic fixing part 110 so as to surround the mounting object. The engagement position between the fixing member 120 and the elastic fixing part 110 can be adjusted between a first position and a second position of the elastic fixing part 110 so that the pressure provided to the bone conduction vibrator by the elastic fixing part 110 is always within a predetermined pressure range. In some embodiments, the predetermined pressure range is 0.2N to 2N. In some embodiments, the predetermined pressure range may be 0.5N to 2N. Preferably, the predetermined pressure range may be 0.8N to 2N. More preferably, the predetermined pressure range may be 1.2N to 1.8N.

[0043] In some embodiments, the fixing member 120 may be a pin buckle, which engages with one or more locking holes in the elastic fixing part 110 to realize a removable fixation between the fixing member 120 and the elastic fixing part 110. The first position may be a position of a locking hole or another position in the elastic fixing part 110 (e.g., a position between the locking holes), and the second position may be a locking hole that is a certain distance away from the first position. By adjusting the position of the locking hole that engages with the pin buckle to adjust the tension with which the elastic fixing part 110 surrounds the wearing object, it is possible to realize the adjustment of the magnitude of pressure that the bone conduction vibrator located between the elastic fixing part 110 and the wearing object exerts on the wearing object. For more information on the pin buckle and the locking hole, please refer to FIG. 3 and related descriptions. In some embodiments, the fastening member 120 is a hook and loop fastener, and the fastening member 120 may include a loop surface structure, one side of the loop surface structure is connected to one end of the elastic fastening portion 110, the elastic fastening portion 110 includes a plurality of hook surfaces spaced apart along the length of the elastic fastening portion 110, the hook surfaces are located at the end of the elastic fastening portion 110 away from the loop surface structure, and the loop surface sides of the loop surface structure can be bonded to the plurality of spaced apart hook surfaces located on the elastic fastening portion 110 respectively to realize the releasable fastening of both ends of the elastic fastening portion 110. The first position may be a hook surface position or another position on the elastic fastening portion 110 (e.g., a position between the hook surfaces), and the second position may be a hook surface that is a certain distance away from the first position. By adjusting the position of the hook surface at the other end that is bonded to the loop surface at one end, the tension of the elastic fixing part 110 surrounding the target can be adjusted, thereby adjusting the amount of pressure that the bone conduction vibrator located between the elastic fixing part 110 and the target exerts on the target. For more information on the loop surface and the hook surface, please refer to FIG. 4 and the related description. In some embodiments, the fixing member 120 may be a ring buckle, which engages with a locking groove in the elastic fixing part 110 to realize a removable fixation between the fixing member 120 and the elastic fixing part 110.The first position may be a position of a certain locking groove or another position (e.g., a position between the locking grooves) in the elastic fixing part 110, and the second position may be a certain locking groove that is a certain distance away from the first position. By adjusting the position of the locking groove that engages with the annular buckle to adjust the tension with which the elastic fixing part 110 surrounds the wearing object, it is possible to realize adjustment of the magnitude of pressure that the bone conduction vibrator located between the elastic fixing part 110 and the wearing object exerts on the wearing object. For more explanation of the annular buckle and the locking groove, please refer to Figures 5A and 5B and related explanations.

[0044] The bone conduction vibrator is located between the elastic fixing part 110 and the wearing subject, and contacts the wearing subject with a certain pressure due to the action of the elastic fixing part 110. In some embodiments, the bone conduction vibrator may include a contact surface that directly or indirectly contacts the wearing subject, and pressure is applied to the wearing subject by the contact surface. An audio signal output from the bone conduction vibrator is similarly transmitted to the wearing subject via the contact surface.

[0045] In some embodiments, the fixing assembly 100 may further include a connection part 130 that connects the bone conduction vibrator and the fixing assembly 100. In some embodiments, the connection part 130 may be located on a side of the elastic fixing part 110 close to the mounting target, and the connection part 130 may connect the bone conduction vibrator such that the bone conduction vibrator is located between the elastic fixing part 110 and the mounting target. In some embodiments, the connection part 130 may be installed on the bone conduction vibrator to connect the fixing assembly 100 to the bone conduction vibrator. In some embodiments, the connection part 130 may be installed on a side of the bone conduction vibrator away from the mounting target, or on a side of the bone conduction vibrator perpendicular to the mounting target. In some embodiments, the connection part 130 may be a fixing base, and the fixing base is installed on the bone conduction vibrator or the elastic fixing part 110. For example, one side of the fixing base is connected to the elastic fixing part 110, and the other side of the fixing base is connected to a side of the bone conduction vibrator away from the mounting target or a side of the bone conduction vibrator perpendicular to the mounting target. In some embodiments, the connection portion 130 may be the structure after the adhesive has solidified, for example by applying an adhesive to the elastic fixing portion 110 and / or the bone conduction transducer, the adhesive fixing the fixing member 120 to the side of the bone conduction transducer away from the attachment target.

[0046] Hereinafter, a fixing assembly will be exemplarily described as shown in FIG. 2 and FIG. 3. FIG. 2 is a schematic diagram of a fixing assembly according to some embodiments of the present specification. FIG. 3 is a schematic diagram of a fixing assembly according to some other embodiments of the present specification. As shown in FIG. 2 and FIG. 3, in some embodiments, the fixing assembly 200 may include an elastic fixing part 210 and a fixing member 220. In some embodiments, the elastic fixing part 210 may be a strip-shaped structure, and the elastic fixing part 210 has a plurality of locking holes 211 distributed at intervals along its length direction (X direction shown in FIG. 2). Correspondingly, the fixing member 220 may be a pin buckle member, and the fixing member 220 may include a pin buckle 221, which is fixed to one end of the elastic fixing part 210, and the other end of the fixing member 220 and the elastic fixing part 210 is removably fixed by fitting the pin buckle 221 into the locking hole 211. By adjusting the pin buckle 221 to fit into the locking hole 211 at different positions and adjusting the tension with which the elastic fixing part 210 surrounds the target, it is possible to adjust the magnitude of pressure that the bone conduction vibrator located between the elastic fixing part 210 and the target applies to the target. Specifically, the closer the locking hole 211 into which the pin buckle 221 is fitted is to the end of the elastic fixing part 210 farther from the fixing member 220, the smaller the pressure becomes. Note that one end of the elastic fixing part 210 and the other end of the elastic fixing part 210 in this embodiment may be both opposing ends of a band-shaped structure, or may be both opposing ends after cutting the ring-shaped elastic fixing part 210 from a certain position.

[0047] In some embodiments, the elastic fastening part 210 is an elastic rubber belt. In some embodiments, a plurality of locking holes 211 are arranged at equal intervals at the end of the elastic fastening part 210 away from the fixing member 220. The engagement of the pin buckle 221 with the locking holes 211 at different positions can realize accurate adjustment of the wearing pressure. In some embodiments, the pin buckle 221 may include a base, a mushroom cap structure and a connecting post, and the mushroom cap structure is connected to the base through the connecting post. In some embodiments, the mushroom umbrella structure may be a hemisphere, the diameter of the hemisphere is larger than the diameter of the locking hole 211, and the elastic fastener 210 is an elastic structure, and the mushroom umbrella structure can pass through the locking hole 211 by external force, so that when the pin buckle 221 is inserted into the locking hole 211, the locking hole 211 engages with the connecting post, and the mushroom umbrella structure and the base play a restricting role to prevent the elastic fastener 210 from being separated from the pin buckle 221. By way of example only, the diameter of the locking hole 211 may be 3 mm, and the diameter of the mushroom umbrella may be 4 mm. It should be noted that the shape and size of the pin buckle 221 may be changed according to actual needs, for example, the diameter of the hemisphere may be other dimensions, or the pin buckle 221 may have a structure such as a hook with one end hooked.

[0048] In some embodiments, the elastic fixing part 210 may include a first position and a second position arranged in sequence along its length direction. The first position is a connection position between the fixing member 220 and the elastic fixing part 210 when the elastic fixing part 210 surrounds the test subject and is in a natural state, and the second position is a connection position between the fixing member 220 and the elastic fixing part 210 when the elastic fixing part 210 surrounds the test subject and provides the bone conduction transducer with a pressure within a predetermined pressure range acting on the test subject.

[0049] In some embodiments, at least one of the multiple locking holes 211 may be a fixed locking hole, and the position of the fixed locking hole is a second position, and when the pin buckle 221 is fitted into the fixed locking hole, the elastic fixing part 210 surrounds the mounting target, and the fixing member 220 can be fixed to the second position. The second position may be any position in the elastic fixing part 210, and it is only necessary that the product of the distance between the second position and the first position and the elastic coefficient k of the elastic fixing part 210 is between the minimum threshold of pressure on the mounting target of the bone conduction vibrator and the maximum threshold of pressure on the mounting target of the bone conduction vibrator. Therefore, the second position may be one or more. When there are multiple fixed locking holes, the second position is also multiple, and the position of each fixed locking hole is a second position, that is, the product of the distance from each fixed locking hole to the first position and the elastic coefficient of the elastic fixing part 210 is between the minimum threshold of tension and the maximum threshold of tension.

[0050] In some embodiments, the distance between two adjacent locking holes 211 among the multiple locking holes 211 is x 2 That is, when the pin buckle 221 is removed from the locking hole 211 and inserted into another locking hole 211 adjacent to the locking hole 211, the increment F of the tension of the elastic fixing part 210 is 0 =k×x 2 The elastic coefficient k of the elastic fixing portion 210 and the distance x between two adjacent locking holes 211 are 2 By adjusting the amount of deformation of the elastic fixing part 210, x 2 The increment in tension F when 0can be adjusted. By adjusting the position of the locking hole 211 into which the pin buckle 221 is fitted, the amount of deformation of the elastic fixing part 210 can be adjusted, and the product of the amount of deformation of the elastic fixing part 210 and the elastic coefficient of the elastic fixing part 210 is the magnitude of the tension of the elastic fixing part 210. Therefore, the magnitude of the tension of the elastic fixing part 210 can be easily determined based on the position of the locking hole 211 into which the pin buckle 221 is fitted, and the magnitude of the pressure on the attachment target of the bone conduction vibrator can be determined without using a measuring device, simplifying the operation steps during the bone conduction test. In addition, by adjusting the position of the locking hole 211 into which the pin buckle 221 is fitted, the pressure on the attachment target of the bone conduction vibrator can be easily and accurately adjusted to ensure that the pressure on the attachment target of the bone conduction vibrator is within a predetermined pressure range (i.e., between the minimum pressure threshold and the maximum pressure threshold).

[0051] Merely as an exemplary explanation, the plurality of locking holes 211 may include a first locking hole 212, a second locking hole 213 and a third locking hole 214, and the third locking hole 214, the first locking hole 212 and the second locking hole 213 are installed adjacent to each other and arranged in sequence along a direction away from the fixing member 220 of the elastic fixing part 210. The direction away from the fixing member 220 of the elastic fixing part 210 (X direction shown in FIG. 2) refers to the direction along the length direction of the elastic fixing part 210 from the end where the fixing member 220 is located to the end where the locking hole 211 is located. The distance between adjacent locking holes 211 is x 2 That is, the distance between the third locking hole 214 and the first locking hole 212, and the distance between the second locking hole 213 and the first locking hole 212 are both x 2 The deformation amount of the elastic fixing part 210 is x 2 With each increase, the tension of the elastic fastener 210 increases by F 0 Increase.

[0052] As shown in FIG. 2, in some embodiments, the first position may be located between any two adjacent locking holes 211, and the fixed locking hole (i.e., the second position) is the mth locking hole 211 away from the first position, and when the pin buckle 221 is fitted into the fixed locking hole, the pressure is F0 ×(x 1 / x 2 +m-1), and F 0 ×(x 1 / x 2 +m-1) is within a given pressure range, x 1 is the distance between the first locking hole on the side away from the fixing member 220 and the first position in the direction away from the fixing member 220 of the elastic fixing part 210, and x 2 is the distance between two adjacent locking holes 211, and F 0 is the tension of the elastic fixing part 210 when the deformation amount of the elastic fixing part 210 is the distance between two adjacent locking holes 211.

[0053] Specifically, as shown in FIG. 2, the first position is located between the third locking hole 214 and the first locking hole 212. When the pin buckle 221 is fitted into the first locking hole 212, the deformation amount x of the elastic fixing part 210 is x=x 1 The pressure applied to the subject wearing the bone conduction transducer is F=k×x 1 =F 0 ×(x 1 / x 2 When the pin buckle 221 is fitted into the second locking hole 213, the deformation amount x of the elastic fastening part 210 is x=x 1 +x 2 The pressure applied to the subject wearing the bone conduction transducer is F = F 0 ×(x 1 / x 2 +1), and when the pin buckle 221 is fitted into the n-th locking hole 211 on the side away from the fixing member 220 at the first position along the direction away from the fixing member 220 of the elastic fixing part 210, the pressure F on the attachment target of the bone conduction vibrator is F = F 0 ×(x 1 / x 2 +n-1), where n is a natural number greater than 0. When the pin buckle 221 is fitted into a different locking hole 211, the pressure on the object to which the bone conduction vibrator is attached is F=F 0 ×(x 1 / x 2+n-1), and there is no need to use other test methods to test the pressure on the object to which the bone conduction vibrator is attached, thus simplifying the operation steps for testing the bone conduction vibrator. In addition, by adjusting the position of the fixing locking hole, the pressure on the object to which the bone conduction vibrator is attached can be easily and accurately adjusted, and it is possible to ensure that the pressure on the object to which the bone conduction vibrator is attached is within a predetermined pressure range. The fixing locking hole here is the m-th locking hole 211 on the side away from the fixing member 220 at the first position in the direction away from the fixing member 220 of the elastic fixing part 210, and when the pin buckle 221 is fitted into the fixing locking hole, the pressure on the object to which the bone conduction vibrator is attached is m×F 0 and m×F 0 is within a predetermined pressure range, m is also a natural number greater than 0, and m is some specific natural number among the natural numbers indicated by n. Note that the fixing locking hole may be some specific locking hole among the multiple locking holes 211, and when the pin buckle 211 is fitted into the fixing locking hole, the pressure on the object to which the bone conduction vibrator is attached is within a predetermined pressure range.

[0054] As a mere example, the predetermined pressure range for the subject to which the bone conduction vibrator is attached is 0.6 to 1.2 N, i.e., the minimum threshold pressure for the subject to which the bone conduction vibrator is attached is 0.6 N, and the maximum threshold pressure for the subject to which the bone conduction vibrator is attached is 1.2 N. 0 is 0.6 N, that is, when the deformation amount of the elastic fastening part 210 and the distance between the adjacent fastening holes 211 are the same, the change in tension of the elastic fastening part 210 is 0.6 N. When the pin buckle 21 is fitted into the second fastening hole 213 shown in FIG. 2, the tension of the elastic fastening part 210 is 0.6×(x 1 / x 2 +1) and is within the predetermined pressure range of 0.6 N to 1.2 N. Here, n=2 means that the second locking hole 211 on the side away from fixing member 220 at the first position in the direction away from fixing member 220 of elastic fixing part 210 is the fixed locking hole.

[0055] Distance x between two adjacent locking holes 211 2and / or the value of the elastic coefficient k of the elastic fixing portion 210, 0 If the value can be changed, the position of the fixed locking hole will change accordingly. For example, F 0 The value is adjusted to 0.3 N. At this time, the tension of the elastic fixing part 210 is 0.3×(x 1 / x 2 +n-1), where n is 3 or 4, the tension of the elastic fixing part 210 is within the threshold range of 0.6N to 1.2N. In some embodiments, m may be 3 or 4, that is, the third locking hole 211 and the fourth locking hole 211 on the side of the elastic fixing part 210 away from the fixing member 220 at the first position in the direction away from the fixing member 220 are both fixed locking holes. Regardless of whether the pin buckle 221 is fitted into the third locking hole 211 or the fourth locking hole 211, it is possible to ensure that the tension of the elastic fixing part 210 is within the threshold range, and further ensure that the pressure on the mounting target of the bone conduction vibrator is within a predetermined pressure range. In addition, when the pin buckle 221 is fitted into the three engagement holes 211, it can be easily seen that the tension of the elastic fixing part 210 at this time is 0.6N to 0.9N, and when the pin buckle 221 is fitted into the fourth engagement hole 211, it can be easily seen that the tension of the elastic fixing part 210 at this time is 0.9N to 1.2N.

[0056] In some embodiments, the first position may be located at the position of any one of the locking holes 211, and the fixed locking hole is the m-th locking hole 211 on the side away from the fixing member 220 at the first position in the direction away from the fixing member 220 of the elastic fixing part 210, and when the pin buckle 221 is fitted into the fixed locking hole, the pressure on the mounting target of the bone conduction vibrator is m×F 0 and m×F 0 is within a predetermined pressure range.

[0057] 3, the elastic fixing part 210 surrounds the mounting object, and when the elastic fixing part 210 is in a natural state, the pin buckle 221 corresponds to the position of the third locking hole 214, that is, in this embodiment, the first position of the elastic fixing part 210 is the position of the third locking hole 214. When the pin buckle 221 is fitted into the first locking hole 212, the pressure F on the mounting object of the bone conduction vibrator is expressed as F=k×x 2 =F 0 When the bone conduction transducer is fitted into the second engagement hole 213, the pressure F applied to the attachment target is F=k×2x 2 =2F 0 When the elastic fixing portion 210 is fitted into the n-th locking hole 211 on the side away from the fixing member 220 at the first position in the direction away from the fixing member 220, the pressure F on the attachment target of the bone conduction vibrator is F=nF 0 When the pin buckle 221 is fitted into a different locking hole 211, the pressure on the object to which the bone conduction vibrator is attached is F=nF 0 Since there is no need to use other testing methods to test the pressure applied to the object to which the bone conduction vibrator is attached, the operation steps for testing the bone conduction vibrator are simplified. In addition, by adjusting the position of the fixing hole, the pressure applied to the object to which the bone conduction vibrator is attached can be easily and accurately adjusted, and it can be ensured that the pressure applied to the object to which the bone conduction vibrator is attached is within a predetermined pressure range.

[0058] As a mere example, the pressure threshold range for the subject wearing the bone conduction vibrator is 0.6N to 1.2N, i.e., the minimum pressure threshold for the subject wearing the bone conduction vibrator is 0.6N, and the maximum pressure threshold for the subject wearing the bone conduction vibrator is 1.2N. 0is 0.6 N, that is, when the deformation amount of the elastic fixing part 210 and the distance between the adjacent locking holes 211 are the same, the tension change amount of the elastic fixing part 210 is 0.6 N. In the embodiment shown in Fig. 3, the pin buckle 221 can be selected to be fitted into the first locking hole 211 or the second locking hole 211 on the side farther from the fixing member 220 at the first position in the direction away from the fixing member 220 of the elastic fixing part 210. When the pin buckle 221 is fitted into the first locking hole 211 on the side of the elastic fastening part 210 away from the fixing member 220 at the first position in the direction away from the fixing member 220, the tension of the elastic fastening part 210 is 0.6 N, and when the pin buckle 221 is fitted into the second locking hole 211 on the side of the elastic fastening part 210 away from the fixing member 220 at the first position in the direction away from the fixing member 220, the tension of the elastic fastening part 210 is 1.2 N, thereby ensuring that the tension of the elastic fastening part 210 is within the threshold range of 0.6 N to 1.2 N. In this embodiment, m may be 1 or 2, that is, the first locking hole 211 and the second locking hole 211 on the side of the elastic fastening part 210 away from the fixing member 220 at the first position in the direction away from the fixing member 220 are both fixed locking holes in this embodiment.

[0059] Distance x between two adjacent locking holes 211 2 and / or the elastic coefficient k of the elastic fixing portion 210, 0 Changing the value will result in a corresponding change in the location of the fixed locking hole. For example, F 0The value is adjusted to 0.3 N. At this time, the tension of the elastic fixing part 210 is 0.3n, and when n is 2, 3, or 4, the tension of the elastic fixing part 210 is within the threshold range of 0.6 N to 1.2 N. In this case, m may be equal to 2, 3, or 4, that is, the second locking hole 211, the third locking hole 211, and the fourth locking hole 211 on the side away from the fixing member 220 at the first position in the direction away from the fixing member 220 of the elastic fixing part 210 are all fixed locking holes in this embodiment. Regardless of whether the pin buckle 221 is fitted into the second, third or fourth locking hole 211 on the side of the elastic fixing part 210 away from the fixing member 220 at the first position in the direction away from the fixing member 220, the tension of the elastic fixing part 210 is guaranteed to be within a threshold range, and further, it is guaranteed that the pressure on the mounting target of the bone conduction vibrator is within a predetermined pressure range. In addition, when the pin buckle 221 is fitted into the second locking hole 211, it is easy to know that the tension of the elastic fixing part 210 at this time is 0.6 N, when the pin buckle 221 is fitted into the third locking hole 211, it is easy to know that the tension of the elastic fixing part 210 at this time is 0.9 N, and when the pin buckle 221 is fitted into the fourth locking hole 211, it is easy to know that the tension of the elastic fixing part 210 at this time is 1.2 N.

[0060] In addition, the distance between the locking holes 211 may be the distance between the centers of the locking holes 211. The distance between the locking holes 211 and the first position may be the distance from the center of the locking holes 211 to the central axis of the pin buckle 221 when the elastic fixing part 210 surrounds the mounting object and is in a natural state.

[0061] In some embodiments, the pressure F on the object to which the bone conduction vibrator is attached may be within a predetermined pressure range. In some embodiments, the predetermined pressure range may be 0.2N to 2N. In some embodiments, the predetermined pressure range may be 0.3N to 1.8N. Preferably, the predetermined pressure range may be 0.4N to 1.6N. More preferably, the predetermined pressure range may be 0.5N to 1.5N. The range of the pressure F can be adjusted according to various objects to be attached. A preferred range of the predetermined pressure range may be 0.6N to 1.2N, that is, the minimum threshold of the predetermined pressure range is 0.6N, and the maximum threshold of the predetermined pressure range is 1.2N. The elastic fixing part 210 and the fixing member 220 are engaged and installed to ensure that the elastic fixing part 210 generates a pressure F between the minimum threshold and the maximum threshold, thereby ensuring that the elastic fixing part 210 can generate a pressure F in the threshold range. At the same time, by adjusting the elastic modulus of the elastic fixing part 210 and the hole spacing L of the two adjacent locking holes 211, the magnitude of the pressure F and the change range of the pressure F can be adjusted, so as to provide a more accurate pressure F and improve the fixing effect of the elastic fixing part 210.

[0062] In some embodiments, the fixing member 220 may be replaced by a male buckle (not shown), which has a columnar structure protruding from its main body structure, and the multiple locking holes 211 may be replaced by multiple female buckles (not shown), which have holes in the middle of the female buckle that engage with the columnar body of the male buckle. Specifically, the holes are groove-shaped, and the columnar body of the male buckle engages with the hole of the female buckle to realize the fixing of the elastic fixing part and the fixing member. The multiple female buckles distributed at intervals are distributed along the length of the elastic fixing part, and the male buckle is fixed to one end of the elastic fixing part, and the fixing member and the other end of the elastic fixing part are releasably fixed by fitting the male buckle into the female buckle. By adjusting the male buckle to fit into the female buckle at different positions, the tension of the elastic fixing part surrounding the wearing object can be adjusted, thereby realizing the adjustment of the pressure applied to the wearing object by the bone conduction vibrator located between the elastic fixing part and the wearing object. The specific positions and structures of the female buckle and the male buckle are similar to the fixing assemblies shown in Figures 2 and 3, and can be referred to correspondingly.

[0063] The fixing member may have another structure. For example, the fixing member may have a wound structure, and the tension of the elastic fixing part when it surrounds the mounting object is adjusted by adjusting the length of the wound elastic fixing part. For example, the fixing member may be a pin buckle member having locking teeth, and the elastic fixing part has a plurality of locking grooves installed at intervals, and the tension of the elastic fixing part when it surrounds the mounting object is adjusted by adjusting the pin buckle member to be fixed in different locking grooves. Hereinafter, fixing members with different structures will be described as shown in Figures 4, 5A, and 5B.

[0064] FIG. 4 is a schematic diagram of a fastening assembly according to some embodiments of the present disclosure. As shown in FIG. 4, the fastening assembly 400 may include an elastic fastening part 410 and a fastening member 420. The elastic fastening part 410 is similar to the elastic fastening part 210 shown in FIG. 2, and the fastening member 420 is a hook-and-loop fastener, which includes a loop surface 421 and a hook surface 422. The loop surface 421 is laid and fixed at one end of the elastic fastening part 410, and a plurality of hook surfaces 422 are distributed at intervals along the length direction (X direction shown in FIG. 4) of the elastic fastening part 410 at the other end of the elastic fastening part 410. The loop surface 421 and the hook surface 422 are bonded to each other to realize that the fastening member 420 fastens the elastic fastening part 410 so as to surround the attachment object. By adjusting the loop surface 421 to be bonded to the hook surface 422 at different positions and adjusting the tension with which the elastic fixing part 410 surrounds the target, it is possible to adjust the magnitude of pressure that the bone conduction vibrator located between the elastic fixing part 410 and the target applies to the target. For an explanation of the specific distribution of the first position, the second position and the hook surface 422 in the elastic fixing part 410, please refer to the explanation of the locking hole 211 in Figures 2 and 3.

[0065] In some embodiments, the positions of the loop surface 421 and the hook surface 422 can be interchanged. Specifically, the hook surface 422 is laid and fixed at one end of the elastic fastener 410, and the multiple loop surfaces 421 are spaced apart and distributed along the length of the elastic fastener 410 at the other end.

[0066] FIG. 5A is a schematic diagram of a fixing assembly according to some other embodiments of the present specification. As shown in FIG. 5A, the fixing assembly 500 may include an elastic fixing part 510 and a fixing member 520. The elastic fixing part 510 is similar to the elastic fixing part 210 shown in FIG. 2, and the fixing member 520 is an annular buckle member, which includes an annular buckle 521. The annular buckle 521 is fixed to one end of the elastic fixing part 510, and the elastic fixing part 510 has a plurality of locking grooves 522 distributed at intervals along its length direction (X direction shown in FIG. 5A). The annular buckle 521 engages with the locking groove 522 to realize that the fixing member 520 fixes the elastic fixing part 510 so as to surround the wearing object. By adjusting the annular buckle 521 to engage with the locking groove 522 at different positions and adjusting the tension with which the elastic fixing part 510 surrounds the wearing object, it is possible to adjust the magnitude of pressure that the bone conduction vibrator located between the elastic fixing part 510 and the wearing object applies to the wearing object. For an explanation of the first position and the second position of the elastic fixing part 510, please refer to the related explanations of Figures 2 and 3.

[0067] 5B is a schematic diagram of an engagement of an annular buckle member according to some embodiments of the present disclosure. In some embodiments, as shown in FIG. 5B, the annular buckle 521 may be an annular structure, and the inner wall of the annular buckle 521 is provided with a bump 5211 that engages with the locking groove 522. The thickness of the annular buckle 521 is matched with the thickness of the elastic fastener 510, so that when the end of the elastic fastener 510 with the locking groove 522 passes through the annular buckle 521, the bump 5211 in the annular buckle 521 is fitted into the locking groove 522, thereby realizing the engagement between the annular buckle 521 and the locking groove 522. For illustrative purposes only, by applying a force to the elastic fastener 510 along the direction of the elastic fastener 510 toward the annular buckle 521, the bump 5211 in the annular buckle 521 will break away from the previous locking groove 522 and fit into the next adjacent locking groove 522 until it engages with the locking groove 522 at the appropriate position. By biasing the elastic fixing part 510 in a direction away from the annular buckle 521, the bumps 5211 in the annular buckle 521 can be released from the multiple locking grooves 522 in order until the end of the elastic fixing part 510 where the locking grooves 522 are provided is released from the annular buckle 521. The thickness of the elastic fixing part 510 is the distance between the side where the locking grooves 522 of the elastic fixing part 510 are provided and the opposite side, and the thickness of the annular buckle 521 is the distance between the side of the inner wall where the bumps 5211 of the annular buckle 521 are provided and the opposite side. In some embodiments, bumps 5211 are provided on both sides of the two inner walls facing each other in the thickness direction of the annular buckle 521, and locking grooves 522 are provided on both sides of the two opposing sides of the elastic fixing part 510 in the thickness direction. When the end of the elastic fixing part 510 on which the locking grooves 522 are provided passes through the annular buckle 521, the two opposing bumps 5211 in the annular buckle 521 are respectively fitted into the two opposing locking grooves 522 in the elastic fixing part 510, thereby achieving a stronger engagement between the annular buckle 521 and the locking grooves 522.

[0068] As shown in Figures 2 and 3, and further Figures 6 to 8, Figure 6 is a schematic diagram of a fixing assembly relating to some embodiments of the present specification, Figure 7 is a schematic diagram of the fixing member shown in Figure 6, and Figure 8 is a schematic diagram of engagement between the elastic fixing portion and the fixing member shown in Figure 6.

[0069] As shown in Fig. 6, the fastening assembly 600 may include an elastic fastening part, which may include a first belt 611, a second belt 612 and a connecting belt 613, in which the first belt 611 and the second belt 612 are arranged side by side, and the connecting belt 613 connects the first belt 611 and the second belt 612. Specifically, the first belt 611, the second belt 612 and the connecting belt 613 combine to form an elastically stretchable H-shaped belt. When the first belt 611 and the second belt 612 elastically surround the wearing object, the stretch distances on both sides are the same, so that the deformation of the entire first belt 611 and the second belt 612 is relatively uniform.

[0070] In some embodiments, the number of the connecting belts 613 may be one or more. For example, when the number of the connecting belts 613 is one, the connecting belt 613 may be disposed at an intermediate position or any other position along the length direction of the first belt 611 and the second belt 612. Also, when the number of the connecting belts 613 is two, in some embodiments, the two connecting belts 613 may be disposed at both ends of the first belt 611 and the second belt 612, respectively, or at any other position where the first belt 611 and the second belt 612 can be connected.

[0071] As further shown in FIG. 6, the connecting belt 613 is disposed at an intermediate position along the length of the first belt 611 and the second belt 612, and the first belt 611 has a plurality of fourth locking holes 6111 disposed at intervals along its length. Specifically, the plurality of fourth locking holes 6111 are disposed symmetrically at both ends of the first belt 611 with the connecting belt 613 at the center, and the two symmetrically disposed fourth locking holes 6111 form a pair. The second belt 612 has a plurality of fifth locking holes 6121 disposed at intervals along its length. Specifically, the plurality of fifth locking holes 6121 are disposed symmetrically at both ends of the second belt 612 with the connecting belt 613 at the center, and the two symmetrically disposed fifth locking holes 6121 form a pair. The fourth locking hole 6111 and the fifth locking hole 6121 arranged at intervals from each other along the spacing direction between the first belt 611 and the second belt 612 form a set, i.e., one set of locking holes includes one set of fourth locking holes 6111 and one set of fifth locking holes 6121, and the fourth locking holes 6111 and the fifth locking holes 6121 are arranged at intervals from each other along the spacing direction between the first belt 611 and the second belt 612.

[0072] The multiple fourth locking holes 6111 do not have to be symmetrically disposed on both ends of the first belt 611 with the connecting belt 613 at the center, and the multiple fifth locking holes 6121 do not have to be symmetrically disposed on both ends of the second belt 612 with the connecting belt 613 at the center. For example, one end of the first belt 611 and the second belt 612 has one set of locking holes, and the other ends of the first belt 611 and the second belt 612 have multiple sets of locking holes.

[0073] As shown in FIGS. 6 and 7, in some embodiments, the fixing member 620 may be a pin buckle member, which may include a pin buckle base 623 and a pin buckle, and one end of the pin buckle is connected to the pin buckle base 623. The pin buckle is fitted to each pair of locking holes in the first belt 611 and the second belt 612. For example, the magnitude of the pressure F of the elastic fixing part is adjusted by inserting the pin buckle into the multiple fourth locking holes 6111 and the multiple fifth locking holes 6121. Specifically, when the pin buckle is fitted into the two corresponding fourth locking holes 6111 and the two corresponding fifth locking holes 6121, this corresponds to the pin buckle being fitted into one locking hole 211 shown in FIGS. 2 and 3.

[0074] As shown in Figures 7 and 8, the pin buckle may include a first buckle pin 621 and a second buckle pin 622, which are spaced apart from each other along the spacing direction between the first belt 611 and the second belt 612, and the first buckle pin 621 is inserted into the fourth locking hole 6111, and the second buckle pin 622 is inserted into the fifth locking hole 6121.

[0075] In some embodiments, the first buckle pin 621 and the second buckle pin 622 may include a mushroom umbrella structure 6211 and a connecting post 6212, and the mushroom umbrella structure 6211 is connected to the pin buckle base 623 through the connecting post 6212. In some embodiments, the mushroom umbrella structure 6211 may be a hemisphere, and the diameter of the hemisphere is larger than the diameter of the fourth locking hole 6111 and the fifth locking hole 6121, so that the mushroom umbrella structure can pass through the locking hole under external force, thereby preventing the elastic fixing part from being detached from the fixing member 620 when the first buckle pin 621 and the second buckle pin 622 are inserted into the fourth locking hole 6111 and the fifth locking hole 6121 respectively.

[0076] In some embodiments, the fixing member 620 may be fixedly attached to the bone conduction transducer. In some embodiments, the connection may be a fixing material that fixes the fixing member 620 to the side of the bone conduction transducer away from the target, and in some embodiments, the fixing material may be an adhesive or other material that provides a fixed connection between the pin buckle and the bone conduction transducer.

[0077] As shown in Figures 2 and 3, and further Figures 9 to 13, Figure 9 is a schematic diagram of a fixing member relating to some embodiments of the present specification, Figure 10 is a schematic diagram of the fixing assembly shown in Figure 9, Figure 11 is a schematic diagram of the dimensions of the elastic fixing part shown in Figure 9, Figure 12 is a schematic diagram of the fixing seat shown in Figure 9, and Figure 13 is a schematic diagram of the engagement of the elastic fixing part, the fixing seat and the fixing member shown in Figure 9.

[0078] 9, in some embodiments, the elastic fixing part 910 may include a first belt 911, a second belt 912, a third belt 913, and a fixing member 920. One end of the first belt 911 and one end of the second belt 912 are both connected to the third belt 913, and the other end of the first belt 911 and the other end of the second belt 912 are both connected to the fixing member 920. In an embodiment in which the fixing assembly 900 is used for testing a bone conduction vibrator, a guinea pig can be exemplarily described as a wearing subject, and the first belt 911 can at least partially elastically surround the head of the experimental guinea pig, and the second belt 912 at least partially elastically surrounds the neck of the experimental guinea pig. In some embodiments, the first belt 911 elastically surrounds the head of the experimental guinea pig in front of the ears of the experimental guinea pig, and the second belt 912 elastically surrounds the neck of the experimental guinea pig behind the ears of the experimental guinea pig. The connection part (not shown) is installed on the side of the bone conduction vibrator away from the experimental guinea pig and is connected to the elastic fixing part 910 to fix the bone conduction vibrator to the head of the experimental guinea pig. In some embodiments, the connection part and the elastic fixing part 910 can fix the bone conduction vibrator to other positions on the head of the experimental guinea pig. Specifically, when the bone conduction vibrator is fixed to the top of the head of the experimental guinea pig using the elastic fixing part 910 and the connection part, it is necessary to first install the bone conduction vibrator with the connection part installed on the top of the head of the experimental guinea pig, and specifically, it may be installed in the middle of the top of the head of the experimental guinea pig so that the distance from the bone conduction vibrator to the left ear of the experimental guinea pig is equal to the distance from the bone conduction vibrator to the right ear of the experimental guinea pig. Next, the first belt 911 of the elastic fixing part 910 elastically surrounds the front side of the ear of the experimental guinea pig, and the second belt 912 of the elastic fixing part 910 elastically surrounds the back side of the ear of the experimental guinea pig. By installing the first belt 911 and the second belt 912, the bone conduction vibrator can be fixed near the ear of the experimental guinea pig, and at the same time, the ear of the experimental guinea pig can be positioned between the first belt 911 and the second belt 912, thereby preventing the ear of the experimental guinea pig from affecting the attachment of the fixing assembly 900.

[0079] In some embodiments, the third belt 913 has sixth locking holes 914 spaced apart along its length. Specifically, the third belt 913 has a plurality of sets of sixth locking holes 914 spaced apart along its length, each set of sixth locking holes 914 including at least two sixth locking holes 914 spaced apart along the width of the third belt 913, and an indicator 915 is provided between the sixth locking holes 914 of the same set. In some embodiments, the indicator 915 may be one or more of blind holes, letters, numbers, colors, and the like. In some embodiments, the sixth locking holes 914 may be triangular, rectangular, polygonal, track-shaped locking holes, and the like, and the shapes of the plurality of sixth locking holes 914 may be the same or partially the same.

[0080] 10, the fixing member 920 may be a pin buckle member, and in some embodiments, the fixing member 920 may include a fixing seat 923, a first buckle pin 921 and a second buckle pin 922, the first buckle pin 921 and the second buckle pin 922 are spaced apart in the fixing seat 923, and the first buckle pin 921 and the second buckle pin 922 may be inserted into each pair of sixth locking holes 914, and the first buckle pin 921 and the second buckle pin 922 engage with the sixth locking holes 914 at different positions to adjust the magnitude of the pressure F of the elastic fixing portion 910. For more details on the fixing member 920, please refer to the fixing member 620 shown in FIG.

[0081] The buckle pins 921 are installed in accordance with the sixth locking holes 914, and in some embodiments, the number of the buckle pins 921 is two, so that the buckle pins 921 are inserted into the two sixth locking holes 914 of the same set. Specifically, the two-row buckle pins 921 can make the overall deformation of the first belt 911 and the second belt 912 relatively uniform.

[0082] Specifically, when the buckle pin 921 is fitted into the two corresponding sixth locking holes 914, this corresponds to the buckle pin 921 being fitted into one locking hole 211 shown in FIGS.

[0083] In some embodiments, the elastic fastening part 910 further includes a fastening connection part 916 that connects the other end of the first belt 911 and the other end of the second belt 912. A fastening hole 917 is provided in the fastening connection part 916, and a buckle pin 921 is inserted into the fastening hole 917.

[0084] The fixed locking holes 917 are installed in accordance with the sixth locking holes 914 and the buckle pins 921, and in some embodiments, the number of the fixed locking holes 917 is two, and the two buckle pins 921 are inserted into the two fixed locking holes 917 and the two sixth locking holes 914 respectively.

[0085] 9 and 11, in some embodiments, the first belt 911 and the second belt 912 may be arranged in an arc, where the arc length of the first belt 911 is L1, the arc length of the second belt 912 is L2, and the arc length L1 of the first belt 911 is greater than the arc length L2 of the second belt 912. The length of the third belt 913 is L3, and the length of the fixed connection portion 916 is L4.

[0086] In some embodiments, the arc length L1 of the first belt 911 may be 115 mm to 125 mm, the arc length L2 of the second belt 912 may be 105 mm to 115 mm, and the difference between the arc length L1 of the first belt 911 and the arc length L2 of the second belt 912 is 6 mm to 10 mm. Preferably, the arc length L1 of the first belt 911 is 120 mm, and the arc length L2 of the second belt 912 is 112 mm.

[0087] The width of the first belt 911 is D1, the width of the second belt 912 is D2, and the width of the elastic fixing part 910 is D3. In some embodiments, the width of the first belt 911, the second belt 912, and the elastic fixing part 910 can affect the elasticity of their corresponding structures. For example, if the width of the first belt 911, the second belt 912, or the elastic fixing part 910 is too small, on the one hand, the structure is soft and cannot provide sufficient clamping force to the bone conduction vibrator. On the other hand, if the width of the first belt 911, the second belt 912, or the elastic fixing part 910 is too small, it further causes the structural strength to be low and easy to break. Also, for example, if the width of the first belt 911, the second belt 912, or the elastic fixing part 910 is too large, the structure is hard and the clamping force provided to the bone conduction vibrator is too large, which affects the wearing experience. As merely an example, in some embodiments, the width D1 of the first belt 911 may be equal to the width D2 of the second belt 912. For example, the width D1 of the first belt 911 or the width D2 of the second belt 912 may be 3 mm, and the width D3 of the elastic fastening portion 910 may be 16 mm. In some embodiments, the width D1 of the first belt 911 or the width D2 of the second belt 912 and the width D3 of the elastic fastening portion 910 are not limited to the above values ​​and can be adaptively adjusted according to the material and the object of wearing.

[0088] In an embodiment where the fixing assembly is used for testing a bone conduction vibrator, when a guinea pig is used as a test subject, the head structure of the guinea pig can be approximately regarded as a cone-shaped structure, that is, the head circumference in front of the guinea pig's ears and the head circumference behind the ears have a large difference, and if the first belt 911 and the second belt 912 are both linear belt-shaped structures, when the guinea pig wears the fixing assembly, one of the first belt 911 and the second belt 912 applies too much pressure to the guinea pig's head, and the other applies too little pressure to the guinea pig's head. In some embodiments, the first belt 911 and the second belt 912 may be arranged in a concentric arc shape, and thus the first belt 911 and the second belt 912 have different lengths, which can be applied to the test of a bone conduction vibrator on a guinea pig. In some embodiments, the length and arc angle (central angle) of the first belt 911 and the second belt 912 can be determined based on the head circumference in front of the ears and the head circumference behind the ears of the guinea pig. Specifically, the central angle of the first belt 911 can be calculated based on the arc length L1 of the first belt 911, the arc length L2 of the second belt 912, the width D1 of the first belt 911, the width D2 of the second belt 912, and the width D3 of the elastic fixing part 910, and the calculation formula is as follows:

[0089]

number

[0090]

number

[0091] From equations (2) and (3), the following equation can be obtained:

[0092]

number

[0093] Here, x is the central angle of the first belt 911, and r is the radius corresponding to the central angle of the first belt 911. Similarly, the central angle of the second belt 912 can be calculated using the above formula.

[0094] In some embodiments, the central angle of the first belt 911 may be between 32 degrees and 36 degrees, and the absolute value of the difference between the central angle of the first belt 911 and the central angle of the second belt 912 is less than 2 degrees. In some embodiments, the central angle of the first belt 911 may be between 32 degrees and 35 degrees. In some embodiments, the central angle of the first belt 911 may be between 32 degrees and 34 degrees. Preferably, the central angle of the first belt 911 may be 33 degrees. In some embodiments, the absolute value of the difference between the central angle of the first belt 911 and the central angle of the second belt 912 is less than 1.5 degrees. In some embodiments, the absolute value of the difference between the central angle of the first belt 911 and the central angle of the second belt 912 is less than 1 degree. Preferably, the absolute value of the difference between the central angle of the first belt 911 and the central angle of the second belt 912 is less than 0.5 degrees. Furthermore, the hole interval between two sixth locking holes 914 adjacently installed along the length direction of the third belt 913 is L, and the hole interval between the same pair of sixth locking holes 914 is D4. Note that the subject to be fitted is not limited to the above-mentioned guinea pig, and the subject to be fitted or the test subject may be other individuals, and when the fastening assembly is fitted to other individuals, the lengths or corresponding central angles of the first belt 911 and the second belt 912 can both be adaptively adjusted. For example, the first belt 911 and the second belt 912 may be linear belt-like structures, and both are installed approximately parallel to each other.

[0095] 12, the fixing assembly 900 may further include a fixing seat 930 disposed on a side of the bone conduction transducer away from the mounting target, and a first hook member 931 and a second hook member 932 extending away from the bone conduction transducer are further disposed on the fixing seat 930. In some embodiments, the fixing seat 930 may be the connecting portion 130 described above.

[0096] In some embodiments, the first hook member 931 and the second hook member 932 are spaced apart from each other along the spacing direction between the first belt 911 and the second belt 912. The end of the first hook member 931 fixedly installed on the fixed seat 930 is the fixed end 9311 of the first hook member 931, and the end of the first hook member 931 remote from the fixed seat 930 extends to the second hook member 932 to form the free end 9312 of the first hook member 931. The end of the second hook member 932 fixedly installed on the fixed seat 930 is the fixed end 9321 of the second hook member 932, and the end of the second hook member 932 remote from the fixed seat 930 extends to the first hook member 931 to form the free end 9322 of the second hook member 932. An opening 933 is formed between a free end 9311 of the first hook member 931 and a free end 9322 of the second hook member 932 .

[0097] Specifically, the opening 933 may be the shortest distance between the free end 9312 of the first hook member 931 and the free end 9322 of the second hook member 932, the spacing distance between the fixed end 9311 of the first hook member 931 and the fixed end 9321 of the second hook member 932 is the distance between the point of the fixed end 9311 of the first hook member 931 that is closest to the fixed end 9321 of the second hook member 932 and the point of the fixed end 9321 of the second hook member 932 that is closest to the fixed end 9311 of the first hook member 931, and the spacing distance between the first belt 911 and the second belt 912 is the width D3 of the elastic fixing portion 910.

[0098] In some embodiments, when the first belt 911 and the second belt 912 are installed between the first hook member 931 and the second hook member 932 through the opening 933, the opening 933 may be smaller than the distance between the first belt 911 and the second belt 912 so that the elastic fixing portion 910 is less likely to come off from the fixing seat 930.

[0099] In some embodiments, the spacing distance between the fixed end 9311 of the first hook member 931 and the fixed end 9321 of the second hook member 932 is greater than the spacing distance between the first belt 911 and the second belt 912 .

[0100] In some embodiments, the first hook member 931 and the second hook member 932 may be fixed to the fixed base 930 by a boss, and the distance between the opposing sides of the boss on which the first hook member 931 is mounted and the boss on which the second hook member 932 is mounted may be greater than or less than the spacing distance between the first belt 911 and the second belt 912.

[0101] As shown in FIG. 13, when the elastic fixing portion 910 is engaged with and installed in the fixing seat 930, the first belt 911 and the second belt 912 are installed in the accommodation space formed by the free end of the first hook member 931, the free end of the second hook member 932, and the fixing seat 930, and the first hook member 931 and the second hook member 932 limit the positions of the first belt 911 and the second belt 912.

[0102] In an embodiment in which the fixing assembly is used for testing the bone conduction vibrator, a guinea pig is used as a wearer, and the bone conduction vibrator is pressed against the head of the guinea pig by an elastic fixing part (for example, the elastic fixing part 210 shown in FIG. 2 or FIG. 3, the elastic fixing part 410 shown in FIG. 4, the elastic fixing part 510 shown in FIG. 5A, and the elastic fixing part shown in FIG. 6 and FIG. 9), the bone conduction vibrator transmits an audio signal to the guinea pig, and the guinea pig can detect an electroencephalogram signal generated in response to the vibration signal transmitted from the bone conduction vibrator, and the brain signal is a feedback signal fed back from the wearer. The signal transmission performance of the bone conduction vibrator is determined by comparing the electroencephalogram signal with a predetermined signal strength. The electroencephalogram signal is a test signal obtained by detecting the brain of the wearer after the wearer receives an audio signal, the strength of the electroencephalogram signal is the amplitude of the test signal, and the predetermined signal strength is a predetermined amplitude. It is considered that if the amplitude of the test signal is equal to or greater than the predetermined amplitude value, the information contained in the audio signal can be effectively obtained after the wearer receives the audio signal.

[0103] Specifically, when the pressure F is smaller than the minimum threshold, the strength of the EEG signal at this time is smaller than the predetermined signal strength; when the pressure F is equal to the minimum threshold, the strength of the EEG signal at this time is equal to the predetermined signal strength; when the pressure F is between the minimum threshold and the maximum threshold, the strength of the EEG signal at this time is greater than the predetermined signal strength; when the pressure F is equal to the maximum threshold, the strength of the EEG signal at this time is equal to the predetermined signal strength; and when the pressure F is greater than the maximum threshold, the strength of the EEG signal at this time is smaller than the predetermined signal strength.

[0104] The pressure with which the bone conduction vibrator is pressed against the subject to which it is worn affects the magnitude of the feedback signal of the subject to which it is worn, so that when the pressure with which the bone conduction vibrator is pressed against the subject to which it is worn is between a minimum threshold and a maximum threshold, the strength of the detected brainwave signal is equal to or greater than a predetermined signal strength. By fixing the fixing member fixed to one end of the elastic fixing part to a second position on the elastic fixing part, it is possible to ensure that the tension of the elastic fixing part is within a threshold range (between the minimum threshold and the maximum threshold), and to avoid the problem that the pressure of the bone conduction vibrator against the subject to which it is worn is too small or too large, resulting in a low strength of the feedback signal.

[0105] In some embodiments, the fixing assembly can be used in bone conduction earphones (e.g., headband-type bone conduction earphones). For example, the fixing member causes the elastic fixing part to surround the head of the human body, and the acoustic output unit of the bone conduction earphone is always pressed near the auricle of the human body (e.g., the front, back, upper or lower side of the auricle, etc.) by the action of the elastic fixing part, and the audio signal output from the acoustic output unit of the bone conduction earphone is transmitted to the human body via the human skeleton, muscle tissue, blood, etc., and is sensed by the auditory nerve of the human body. In some embodiments, the tension of the elastic fixing part can be adjusted by adjusting the connection position between the fixing member and the elastic fixing part according to the wearing comfort of the human body, thereby making the wearing experience more comfortable. The fixing assembly allows the bone conduction earphone to adapt to different users and improve the wearing comfort, while the tension of the elastic fixing part can be adjusted to make the pressure of the bone conduction earphone on different human bodies within a predetermined pressure range, so as to avoid the pressure of the bone conduction earphone on the human body being too small, which causes the audio signal received by the human body to be poor, or the pressure of the bone conduction earphone on the human body being too large, which causes discomfort when wearing the bone conduction earphone. Note that the tension threshold range and the predetermined range for different users to wear the bone conduction earphone may be different and can be determined according to actual needs.

[0106] In some embodiments, the fixing assembly can be further applied to wearing a wristwatch or a pedometer. For example, the fixing member fixes the elastic fixing part so as to surround the wrist of the human body. In some embodiments, the fixing assembly can be further used to wear an oximeter or a blood pressure monitor by adjusting the connection position between the fixing member and the elastic fixing part to adjust the tension of the elastic fixing part to make the wearing feeling of the wristwatch or the pedometer more suitable, and the fixing assembly can make the wristwatch or the pedometer adaptable to different human bodies. In some embodiments, the fixing assembly can be further used to wear an oximeter or a blood pressure monitor. The fixing member fixes the elastic fixing part to surround the wrist or the upper arm of the human body, so that in the process of the human body's activity, the oximeter or the blood pressure monitor is always pressed against the skin of the human body under the action of the elastic fixing part, and the subcutaneous blood oxygen content or blood pressure of the human body can be obtained. In some embodiments, the fixing member fixes the elastic fixing part to surround the wrist or the upper arm of the human body to adjust the tension of the elastic fixing part to make the wearing experience more comfortable, according to the wearing feeling of the human body.

[0107] The present specification further provides a mounting device, which may include a fixing assembly and a bone conduction transducer. In some embodiments, the fixing assembly includes an elastic fixing part having a band-like structure and including a first position and a second position, the first position and the second position being distributed at intervals along the length of the elastic fixing part, and a fixing member for fixing the elastic fixing part so as to surround the mounting object, so that the bone conduction transducer is located between the elastic fixing part and the mounting object. When the elastic fixing part surrounds the mounting object and is in a natural state, the fixing member engages with the first position of the elastic fixing part, and when the fixing member engages with the second position, the elastic fixing part provides the bone conduction transducer with a pressure acting on the mounting object, and the pressure is within a predetermined pressure range. Note that the fixing assembly of the mounting device may be similar to the fixing assembly 200, the fixing assembly 400, the fixing assembly 500, the fixing assembly 600, or the fixing assembly 900, and the description thereof will be omitted here. Next, the mounting device will be described with reference to the fixing assembly of FIG. 14.

[0108] Fig. 14 is a schematic diagram of a mounting device according to some embodiments of the present specification. As shown in Fig. 14, the mounting device 1400 may include a fixing assembly and a bone conduction vibrator 1440, and the fixing assembly fixes the bone conduction vibrator 1440 to a mounting target 1450. The fixing assembly is the fixing assembly 600 or the fixing assembly 900 disclosed in the above embodiments, and the description is omitted. The experimental guinea pig is the mounting target 1450, and the mounting device 1400 fixes the bone conduction vibrator 1440 to the head of the experimental guinea pig by the fixing assembly to realize the test of the bone conduction vibrator by the experimental guinea pig.

[0109] In some embodiments, the fixing assembly includes an elastic fixing part 1410 and a connecting part. The elastic fixing part 1410 includes a first belt 1411 and a second belt 1412. The first belt 1411 at least partially elastically surrounds the head of the laboratory guinea pig, and the second belt 1412 at least partially elastically surrounds the neck of the laboratory guinea pig. In some embodiments, the first belt 1411 elastically surrounds the head of the laboratory guinea pig in front of the ears of the laboratory guinea pig, and the second belt 1412 elastically surrounds the neck of the laboratory guinea pig behind the ears of the laboratory guinea pig. The connecting part (not shown) is located on the side of the bone conduction transducer away from the laboratory guinea pig and is connected to the elastic fixing part 1410 to fix the bone conduction transducer to the head of the laboratory guinea pig. In some embodiments, the connecting part and the elastic fixing part 1410 can fix the bone conduction transducer to other positions on the head of the laboratory guinea pig.

[0110] Specifically, when the bone conduction vibrator is fixed to the top of the experimental guinea pig using the elastic fixing part 1410 and the connecting part, the bone conduction vibrator with the connecting part installed must first be installed on the top of the experimental guinea pig, specifically, it may be installed in the middle of the top of the experimental guinea pig so that the distance from the bone conduction vibrator to the left ear of the experimental guinea pig is equal to the distance from the bone conduction vibrator to the right ear of the experimental guinea pig. Next, the first belt 1411 of the elastic fixing part 1410 elastically surrounds the front side of the ear of the experimental guinea pig, and the second belt 1412 of the elastic fixing part 1410 elastically surrounds the rear side of the ear of the experimental guinea pig, and is installed in accordance with the connecting part, and the bone conduction vibrator is further fixed to the top of the experimental guinea pig.

[0111] In some embodiments, the elastic fixing portion 1410 may further include a connecting belt (see connecting belt 613 in FIG. 6 ), which connects the first belt 1411 and the second belt 1412 on the lower jaw side of the experimental guinea pig, so that when the first belt 1411 and the second belt 1412 stretch along the left and right ears of the experimental guinea pig and elastically surround the head and neck of the experimental guinea pig, the stretching distances on both sides are the same, so that the overall deformation of the first belt 1411 and the second belt 1412 is relatively uniform.

[0112] In some embodiments, the fixing assembly may further include a fixing member. The fixing member is placed on the side of the bone conduction transducer away from the head of the experimental guinea pig. In some embodiments, the fixing member further includes a pin buckle extending away from the bone conduction transducer, and the first belt 1411 includes a plurality of first locking holes spaced apart along its length. The second belt 1412 includes a plurality of second locking holes spaced apart along its length. The pin buckle can be inserted into the plurality of first locking holes and the plurality of second locking holes to adjust the clamping force of the first belt 1411 and the second belt 1412. In some embodiments, the pin buckle includes a first buckle pin and a second buckle pin spaced apart from each other along the spacing direction of the first belt 1411 and the second belt 1412, and the first buckle pin is inserted into the first locking hole and the second buckle pin is inserted into the second locking hole.

[0113] Specifically, the step of engaging and installing the elastic fixing part 1410 with the fixing member includes the following steps 1 to 5. In step 1, the fixing member is installed in the center of the top of the experimental guinea pig's head so that the distance from the bone conduction vibrator to the left ear is equal to the distance from the bone conduction vibrator to the right ear. In step 2, the connection belt is installed in close contact with the lower jaw of the experimental guinea pig. In step 3, the first belt 1411 on any one side is elastically stretched along the front side of the ear of the experimental guinea pig until the first buckle pin is inserted into one of the first locking holes in the first belt 1411. In step 4, the first belt 1411 on the other side is elastically stretched along the front side of the ear of the experimental guinea pig until the first buckle pin is inserted into another first locking hole of the same set as the first locking hole in the third step. In step 5, the third step and the fourth step are repeated to insert the second buckle pin into the second locking hole of the same set as the first locking hole in the third step, and the bone conduction vibrator is further fixed to the top of the experimental guinea pig's head.

[0114] In some embodiments, the elastic fixing part 1410 further includes a third belt (see the third belt 913 in FIG. 9). One end of the first belt 1411 and one end of the second belt 1412 are both connected to the third belt, and the other end of the first belt 1411 and the other end of the second belt 1412 are both connected to the fixing member. In some embodiments, the elastic fixing part further includes a fixed connection part (see the fixed connection part 916 in FIG. 10) that connects the other end of the first belt 1411 and the other end of the second belt 1412. A fixed locking hole is provided in the fixed locking hole, and a pin buckle is inserted into the fixed locking hole. In some embodiments, the fixing assembly may further include a fixing seat (see the fixed seat 930 in FIG. 9) in which a first hook member and a second hook member extending away from the bone conduction transducer are further provided. The first hook member and the second hook member are installed at a distance from each other along the distance direction between the first belt 1411 and the second belt 1412. The end of the first hook member fixedly installed on the fixing seat is the fixed end of the first hook member, the end of the first hook member remote from the fixing seat extends to the second hook member to form the free end of the first hook member, the end of the second hook member fixedly installed on the fixing seat is the fixed end of the second hook member, the end of the second hook member remote from the fixing seat extends to the first hook member to form the free end of the second hook member, and an opening is formed between the free end of the first hook member and the free end of the second hook member.

[0115] Specifically, the fixing seat is placed on the side of the bone conduction vibrator away from the head of the experimental guinea pig, the fixing member is placed on the lower jaw side of the experimental guinea pig, the first belt 1411 and the second belt 1412 are placed surrounding the front and back sides of the ears of the experimental guinea pig, respectively, and the third belt and the fixed connection part are fixed to the lower jaw side of the experimental guinea pig by the fixing member.

[0116] The step of engaging and installing the elastic fixing part with the fixing member includes the following steps 1 to 3. In step 1, the fixing member is installed in the center of the top of the experimental guinea pig's head so that the distance from the bone conduction vibrator to the left ear is equal to the distance from the bone conduction vibrator to the right ear. In step 2, the middle parts of the first belt 1411 and the second belt 1412 are installed in an accommodation space formed by the free end of the first hook member, the free end of the second hook member, and the fixing seat, and the first belt 1411 and the second belt 1412 are installed so as to surround the front side and the back side of the ear of the experimental guinea pig, respectively. In step 3, the third belt and the fixing connection part are extended to the lower jaw side of the experimental guinea pig, the pin buckle in the fixing member is inserted into a pair of locking holes and fixed locking holes, and the bone conduction vibrator is further fixed to the top of the experimental guinea pig's head.
