[0002] Head-mounted sound-generating devices, such as headphones, hearing aids, and hearing aids, are suitable for being worn on the human head to enable people to hear sounds. According to the different sound transmission methods, they can be further subdivided. For example, headphones can be divided into ordinary sound-generating headphones that transmit sound through air and bone conduction headphones that transmit sound through bone conduction.
[0003] In the prior art, mechanical buttons are usually set on the head-mounted sound device to control the head-mounted device. For example, a Chinese patent with publication number CN216311653U discloses a button structure, which is set on the head of the earphone, and the bone conduction earphone or other wearable device can be controlled by pressing the panel push switch.
[0004] The setting of mechanical buttons makes the assembly of head-mounted sound equipment more complicated, and it is also easy to cause problems such as water leakage and dust accumulation at the mechanical buttons.
[0005] In addition, switches generally have only two states: triggered and untriggered, which limits the functions of mechanical buttons. For example, a single mechanical button can only realize the power on / off function. If you want to achieve volume adjustment or other control functions, you need to set up another mechanical button. This results in the need to set up multiple sets of mechanical buttons on the head-mounted sound device, and the multiple sets of mechanical buttons may be distributed in different positions. Users need to operate in multiple positions, which is not very convenient to use.
[0006] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. Utility Model Content

[0046] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0047] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.
[0048] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0049] like Figures 1 to 3 As shown, a head-mounted sound-emitting device corresponding to a preferred embodiment of the utility model includes a pressing unit, a pressure calculation module 8 and a control module 5, and the pressing unit includes a housing component 1 and a pressure sensor 3.
[0050] The housing assembly 1 is provided with a pressing area 10 (see Figure 3), the pressing area 10 refers to the part on the shell component 1 used to press to achieve control. The user can realize different functions of the head-mounted sound device by different control methods of the pressing area 10. For example, the user can control different functions of the head-mounted sound device by single-clicking, double-clicking, long pressing or applying different amounts of pressing force.
[0051] The pressure sensor 3 is located in the housing assembly 1 and is connected to the pressing area 10 in a transmission manner. It can detect the user's touch pressing on the pressing area 10 of the head-mounted sound device and generate an electrical signal corresponding to the pressing pressure. The pressure sensor 3 is electrically connected to the pressure calculation module 8 and can transmit the detected electrical signal to the pressure calculation module 8. The pressure calculation module 8 can calculate the magnitude of the pressure based on the electrical signal transmitted by the pressure sensor 3, thereby obtaining a pressure signal corresponding to the pressure of the pressing area 10. Preferably, the signals obtained by the pressure sensor 3 and the pressure calculation module 8 are both analog signals, and the pressure signal calculated by the pressure calculation module 8 contains information such as the pressing pressure, the pressing frequency, the change in the pressing force, and the duration of the pressing force.
[0052] The control module 5 is electrically connected to the pressure calculation module 8, and is used to receive the pressure signal processed by the pressure calculation module 8, and generate a corresponding control signal according to the pressure signal to control the operation of the head-mounted sound device.
[0053] The head-mounted sound-emitting device of the present invention uses a touch-pressing method to control the device. When the user presses the pressing area 10 of the outer shell component 1, the pressing area 10 is deformed. At this time, the pressure sensor 3 detects the pressing force and transmits the detected electrical signal to the pressure calculation module 8. The pressure calculation module 8 calculates the pressure signal based on the electrical signal and transmits the pressure signal to the control module 5 of the head-mounted sound-emitting device. The control of the head-mounted sound-emitting device is realized through the control module 5.
[0054] The utility model eliminates the traditional method of key pressing control and adopts the touch pressing method to control the head-mounted sound device. The traditional key control requires multiple keys to be set on the outer surface of the shell to realize the control of different functions of the head-mounted sound device, while the touch pressing method only needs to use different pressing frequencies or forces on the pressing area 10 to realize the control of different functions of the head-mounted sound device, thereby facilitating the user's operation, while also reducing the space occupied by traditional keys on the head-mounted sound device and simplifying the structure of the head-mounted sound device. In addition, the pressing area 10 is a part of the shell component 1, and the part corresponding to the shell component 1 is integrally formed, so that there is no gap between them (for the device controlled by traditional keys, there is a gap between the shell and the key), which is conducive to improving the waterproof and dustproof performance of the head-mounted sound device.
[0055] like Figure 2As shown, in some embodiments, the shell assembly 1 includes a first shell 11 and a second shell 12, the first shell 11 includes a panel 110 for contacting the facial skin, the second shell 12 includes a back panel 120 that faces away from the facial skin when the head-mounted sound device is worn, and the back panel 120 includes a pressing area 10. The back panel 120 can be set as the pressing area 10 as a whole, or a part of the back panel 120 can be set as the pressing area 10. Typically, the pressing area 10 is the portion of the back panel 120 corresponding to the pressure sensor 3, thereby facilitating the user's manipulation of the pressing area 10. Figure 3 , Fig.10 and Fig.11 In the illustrated case, the dotted line indicates the approximate area of the pressing area 10 on the back plate 120. Preferably, the outer surface of the back plate 120 is smooth, and the pressing area 10 and the surface of its periphery have a smooth transition, which can further improve the effect of preventing dust accumulation.
[0056] In some embodiments, Figure 2 As shown, the head-mounted sound-emitting device further includes a connecting plate 2 disposed in the housing assembly 1, the connecting plate 2 and the back plate 120 are arranged with a relative spacing, the pressure sensor 3 is disposed on the connecting plate 2, and the back plate 120 is provided with a convex column 1201 abutting against the connecting plate 2. When the pressing area 10 of the back plate 120 is pressed, the pressing area 10 is deformed, and the pressing force is transmitted to the connecting plate 2 along the convex column 1201, so that the connecting plate 2 is deformed, and the pressure sensor 3 generates a sensing signal (i.e., an electrical signal) according to the deformation of the connecting plate 2, and transmits the sensing signal to the pressure calculation module 8, and the pressure calculation module 8 calculates the pressure signal and transmits it to the control module 5, thereby realizing the control of the headphone.
[0057] Preferably, the connecting plate 2 is a circuit board, in which case the connecting plate 2 is electrically connected to the control module 5, and the connecting plate 2 can be electrically connected to other electrical components in the housing assembly 1 to transmit signals between the control module 5 and these electrical components. As a feasible implementation, the pressure sensor 3 and the pressure calculation module 8 are both arranged on the connecting plate 2, electrically connected to the connecting plate 2, and then electrically connected to the control module 5 through the connecting plate 2.
[0058] In other embodiments, the pressure sensor 3 may also be disposed on the second housing 12, for example, Figure 4 In the illustrated embodiment, the pressure sensor 3 is disposed on the inner surface of the second housing 12. Figure 5 In the illustrated embodiment, the pressure sensor 3 is disposed inside the second housing 12 .
[0059] In some embodiments, the pressure sensor 3 has a projection on the back plate 120 along the thickness direction of the back plate 120, the geometric center of the pressing area 10 is the same as the geometric center of the projection area, and the pressing center of the pressing area 10 is the same as the geometric center of the pressing area 10. The pressing center refers to the position where the pressure sensor 3 senses most sensitively when pressing. The area of the pressing area 10 is 5.8mm 2 ~161mm 2 , outside the pressing area 10, pressing the shell will not make the pressure sensor 3 generate a sensing signal. It can be understood that the larger the area of the pressing area 10, the larger the pressing range, the easier it is for manual operation, and the smaller the pressing area 10, the less likely it is to accidentally touch the pressing area 10, which can improve the effect of preventing accidental touch. Further optionally, the area of the pressing area 10 is 20mm 2 ~100mm 2 , further optionally, the area of the pressing area 10 is 30mm 2 ~80mm 2 , further optionally, the area of the pressing area 10 is 50mm 2 ~60mm 2 , a better balance can be achieved between convenient pressing and avoiding accidental touches. Optionally, the pressing area 10 can be marked with lines or colors on the outside of the shell, which is more convenient for controlling the earphone. The shape of the pressing area 10 can be, for example, circular or rectangular or other shapes.
[0060] like Figure 1 and Figure 2 As shown, the housing assembly 1 further includes an annular side frame 13 connected between the first housing 11 and the second housing 12. The first housing 11, the side frame 13 and the second housing 12 are sequentially connected as a whole, and the connection method may be, for example, gluing, snapping or welding. The first housing 11 and the side frame 13 and the second housing 12 and the side frame 13 are sealed to improve the waterproof and dustproof performance of the housing assembly 1 as a whole. Figure 2 As shown, the second housing 12 includes an annular shell portion 121 surrounding the outside of the back plate 120, and the annular shell portion 121 extends toward the side frame 13 for fixed connection with the side frame 13. The first housing 11 may also be provided with a similar structure. The pressing area 10 is a part of the back plate 120, and the second housing 12 is obtained by an integral molding method, which is a single part. The pressing area 10 is a part of the back plate 120 rather than a part connected thereto. In the traditional key structure, there is a gap between the key and the housing, which is not conducive to the waterproof and dustproof of the device.
[0061] The connecting plate 2 includes a suspended part and a part connected to the housing assembly 1. The pressure sensor 3 is preferably connected to the suspended part of the connecting plate 2, and the boss 1201 is configured to abut against the suspended part. In this way, when the pressing area 10 is pressed, the boss 1201 is driven to contact the suspended part of the connecting plate 2, and the connecting plate 2 can be deformed more easily, which is conducive to the pressure sensor 3 sensing and generating electrical signals.
[0062] The positions of the suspended part and the connected part are not limited. In some embodiments, the suspended part is located at the outer edge of the connecting plate 2, and the connected part is located in the middle of the connecting plate 2; in other embodiments, the suspended part is located at one end of the connecting plate 2, and the connected part is located at the other end of the connecting plate 2. Figures 6 to 8 As shown, as a preferred embodiment, the side frame 13 is provided with a boss 131, which is arranged on the surface of the inner cavity of the side frame 13, and the boss 131 includes a limiting column 1311; the connecting plate 2 is provided with a through hole 310, and the through hole 310 of the connecting plate 2 is matched with the limiting column 1311 of the side frame 13, and is connected to the surface of the boss 131 facing the second shell 12. The connecting plate 2 is fixedly connected to the side frame 13, and the connection method can be, for example, adhesive connection, screw connection, hot melting of the end of the limiting column 1311, etc. As a preferred embodiment, the number of limiting columns 1311 is four and they are respectively arranged at the four corners of the boss 131 of the side frame 13; at this time, the suspended part is located in the middle of the connecting plate 2, and the connected part is located at the outer edge of the connecting plate 2, and the boss 1201 abuts against the middle of the connecting plate 2, which is convenient for driving the connecting plate 2 to deform.
[0063] In some embodiments, Figure 2 As shown, the boss 1201 directly abuts against the connecting plate 2. For example, it can be arranged that when the back plate 120 is not pressed, the boss 1201 does not contact the connecting plate 2. After the back plate 120 is pressed, the boss 1201 contacts the connecting plate 2. It can also be arranged that the boss 1201 is always in contact with the connecting plate 2.
[0064] In some embodiments, Figure 8 and Fig. 9 As shown, an elastic pad 4 is arranged between the boss 1201 and the connecting plate 2. The elastic pad 4 can be made of elastic materials such as silicone, which can reduce the damage caused by the direct contact between the boss 1201 and the connecting plate 2, and can always keep the boss 1201 in contact with the connecting plate 2, so that the operation applied by the user to the pressing area 10 of the back plate 120 can be sensed more sensitively.
[0065] The type of pressure sensor 3 is not limited, for example, it can be a piezoresistive pressure sensor, a capacitive pressure sensor, a resistive pressure sensor (such as a strain gauge resistance bridge) or a piezoelectric pressure sensor (such as a piezoelectric ceramic sensor) and other sensors for detecting pressure, which can be selected according to actual conditions. Figure 8 and Fig. 9 In the illustrated embodiment, the pressure sensor 3 is preferably a strain type pressure sensor (a resistive pressure sensor, such as a strain gauge resistance bridge). The pressure sensor 3 is arranged on the surface of the connecting plate 2 facing away from the back plate 120 and is arranged corresponding to the boss 1201. The pressure on the back plate 120 is detected by the deformation of the connecting plate 2.
[0066] like Fig.10 As shown, in some embodiments, in order to facilitate the deformation of the pressing area 10 after the user touches and presses it, the thickness of the pressing area 10 is set to be smaller than the wall thickness of other parts of the back plate 120. When the user touches and presses the pressing area 10, the pressing area 10 is thinner than the other parts of the back plate 120, and the pressing area 10 will be more easily deformed. The touch pressing force drives the boss 1201 to move through the deformation of the pressing area 10. Under the action of the boss 1201, the connecting plate 2 is deformed, and the pressure sensor 3 generates a detection signal according to the detected deformation of the connecting plate 2. The detection signal is calculated by the pressure calculation module 8 and transmitted to the control module 5, and the control module 5 is used to control the head-mounted sound device.
[0067] like Fig.11 As shown, in other embodiments, the inner surface of the back plate 120 is provided with an annular groove 1200 surrounding the outside of the pressing area 10. The design of the annular groove 1200 makes it easier for the pressing area 10 to deform to produce sound, thereby improving the sensitivity of the response of the head-mounted sound device.
[0068] In some embodiments, the rigidity of at least the portion of the back plate 120 corresponding to the pressing area 10 is smaller than that of other portions, and for example, materials with different rigidities may be used for integral molding, so that the rigidity of the pressing area 10 is smaller than that of other portions of the back plate 120. As a specific example, the pressing area 10 may be made of plastic or silicone, and other portions of the second housing 12 may be made of plastic plus glass fiber.
[0069] The control module 5 is electrically connected to the connecting plate 2, and the control module 5 can generate a corresponding control signal according to the pressure signal detected by the pressure sensor 3, for example, different control signals are generated according to the different pressures applied by the user to the pressing area 10, different pressing durations, different pressing times, or different pressing intervals, so as to realize different control functions. In some embodiments, the pressure calculation module 8 and the control module 5 are both arranged on the connecting plate 2. In some embodiments, the pressure calculation module 8 is arranged on the connecting plate 2, and the control module 5 can be arranged outside the housing assembly 1, for example, in the control compartment 91 of the head-mounted sound-emitting device, and electrically connected to the connecting plate 2, the pressure calculation module 8, and the pressure sensor 3 through a cable. In other embodiments, the control module 5 and the pressure calculation module 8 are both arranged outside the housing assembly 1, for example, in the control compartment 91 of the head-mounted sound-emitting device, and electrically connected to the connecting plate 2 and the pressure sensor 3 through a cable.
[0070] The pressure calculation module 8 may include, for example, a processor (chip) and circuits supporting the chip, etc., to calculate and output the electrical signal of the pressure sensor 3 .
[0071] The control module 5 may include, for example, a processor (chip) and circuits supporting the chip, etc., which can process and calculate signals and issue control instructions.
[0072] like Fig.12 and Fig.13 As shown, in some embodiments, the head-mounted sound device also includes a wearing detection sensor 6, and the wearing detection sensor 6 and the connecting plate 2 are electrically connected to the control module 5. The wearing detection sensor 6 is used to detect whether the head-mounted sound device is in a wearing state. When it is detected that it is in a wearing state, the control module 5 controls the head-mounted sound device to turn on. When it is detected that it is not in a wearing state, the control module 5 controls the head-mounted sound device to delay or immediately shut down.
[0073] The type of the wearing detection sensor 6 of the head-mounted sound-emitting device is not limited, for example, it can be a capacitive sensor, a pressure sensor or an optical sensor, which can judge the wearing state by detecting the change of capacitance value, the change of pressure value and the change of light, respectively, and can be selected according to the actual situation. When the head-mounted sound-emitting device is in the wearing state, the wearing detection sensor 6 is in contact with the human skin, and the head-mounted sound-emitting device automatically turns on according to the detection signal of the wearing detection sensor 6, which is more user-friendly. Preferably, the wearing detection sensor is an optical heart rate sensor, which can detect the heart rate information of the human body.
[0074] like Fig.14As shown, the head-mounted sound-generating device includes a first earphone head 9 and a second earphone head 90. The first earphone head 9 and the second earphone head 90 are both provided with a sound-generating device 7. The sound-generating device 7 is electrically connected to the connecting plate 2 inside the earphone head, and is electrically connected to the control module 5 through the connecting plate 2, and vibrates under the control of the control module 5. Providing two earphone heads is conducive to improving the user experience, while also maintaining the stability of wearing. The sound-generating device 7 can be either an air conduction sound-generating device or a bone conduction sound-generating device, which can be selected according to actual conditions.
[0075] At least one of the first earphone head 9 and the second earphone head 90 includes a pressing unit; at least one of the first earphone head 9 and the second earphone head 90 includes a wearing detection sensor 6, such as Fig.12 As shown, the wearing detection sensor 6 is arranged to protrude from the second earphone head 90 for contacting the human body with a contact surface 900. As a preferred embodiment, the pressure sensor 3 and the wearing detection sensor 6 are respectively arranged in the first earphone head 9 and the second earphone head 90, so that the weights of the two earphone heads are close to each other, so as to maintain the balance of the user when wearing, thereby improving the wearing comfort.
[0076] Fig.14 The head-mounted sound device shown is a bone conduction headset, which also includes a control compartment 91, a battery compartment 92, and a back hook 93 connected between the control compartment 91 and the battery compartment 92; the first earphone head 9 and the control compartment 91 as well as the second earphone head 90 and the battery compartment 92 are connected via an ear hook 94, and the ear hook 94 adopts an arc-shaped design close to the human ear, thereby improving the stability and comfort of the user when wearing it.
[0077] The sound-generating device 7 is a vibration device. Both the first earphone head 9 and the second earphone head 90 are provided with a sound-generating device, which can transmit sound signals to the human body through vibration. The panel 110 of the first shell 11 is in contact with the human body. As a preferred embodiment, the sound-generating device 7 is arranged corresponding to the panel 110 in contact with the human body and is connected to the first shell 11, thereby improving the efficiency of vibration transmission to the human body.
[0078] Both the back hook 93 and the ear hook 94 are elastic, for example, they can be made of elastic materials such as titanium wire, manganese steel wire, stainless steel wire, etc., with a rubber layer on the outside. Since both the back hook 93 and the ear hook 94 are elastic, a clamping force is generated between the first earphone head 9 and the second earphone head 90 and the human skin, which improves the stability of the bone conduction earphone when worn, and at the same time improves the vibration transmission efficiency.
[0079] The above are only specific implementations of the present invention, and any improvements made based on the concept of the present invention are considered to be within the protection scope of the present invention.
