Description

Technical Field

[0001] This application belongs to the field of communication equipment technology, and specifically relates to an earphone. Background Technology

[0002] Currently, Bluetooth headphones come in two main types: in-ear and bone conduction. While in-ear headphones offer higher sound quality, prolonged wear can cause ear discomfort and they tend to fall out during exercise. Bone conduction headphones avoid the discomfort of in-ear headphones while maintaining awareness of ambient sounds; however, because sound is transmitted through the bone, sound quality is significantly reduced and often inferior to traditional headphones.

[0003] In related technologies, headphones can only adopt either an in-ear design or a bone conduction design, resulting in a single way of wearing headphones that cannot meet the needs of users in different scenarios. Summary of the Invention

[0004] This application aims to provide an earphone that solves the problem of limited earphone wearing methods and can meet the user's needs in different scenarios.

[0005] In a first aspect, embodiments of this application provide an earphone, which includes: an ear stem and a deformable portion, the deformable portion being disposed at one end of the ear stem, a controller being disposed within the ear stem, and a speaker unit and a bone conduction vibrator unit being disposed within the deformable portion, the deformable portion having a first form and a second form; when the deformable portion is in the first form, the controller controls the speaker unit to operate; when the deformable portion is in the second form, the controller controls the bone conduction vibrator unit to operate.

[0006] In this embodiment, the earphone includes a deformable part that can deform, and an ear stem connected to the deformable part. A controller is also provided in the ear stem. A speaker unit and a bone conduction vibrator unit are provided in the deformable part. When the deformable part is in a first state, the controller controls the speaker unit to work, and the sound can be transmitted outward through the sound outlet, so that the earphone operates in the sound production mode of an in-ear earphone. When the deformable part is in a second state, the controller controls the bone conduction vibrator unit to work, and the vibration can be transmitted to the wearer's skull through the deformable part, so that the earphone operates in the sound production mode of a bone conduction earphone. This solves the problem of the single wearing mode of the earphone and can meet the user's usage needs in different scenarios.

[0025] The following is combined with Figures 1 to 10 Describes headphones according to embodiments of this application.

[0026] In some embodiments of this application, an earphone is provided. Figure 1 This illustration shows one of the structural schematic diagrams of the headphones provided in some embodiments of this application. Figure 2 The second schematic diagram of the structure of the earphone provided in some embodiments of this application is shown, such as... Figure 1 and Figure 2 As shown, the headphones 100 include:

[0027] The ear stem portion 102 and the deformable portion 101 are provided at one end of the ear stem portion 102. A controller 122 is provided inside the ear stem portion 102. A speaker unit 103 and a bone conduction resonator unit 104 are provided inside the deformable portion 101. The deformable portion 101 has a first form and a second form. When the deformable portion 101 is in the first form, the controller 122 controls the speaker unit 103 to work. When the deformable portion 101 is in the second form, the controller 122 controls the bone conduction resonator unit 104 to work.

[0028] In this embodiment, the earphone 100 includes a deformable portion 101 and an ear stem 102 connected to each other. The deformable portion 101 is equipped with a speaker unit 103 and a bone conduction resonator unit 104. The ear stem 102 is equipped with a controller 122, which can control the operation of at least one of the speaker unit 103 and the bone conduction resonator unit 104. The deformable portion 101 is a flexible structure, capable of deformation under force. The deformable portion 101 is in different forms under different operating modes. Specifically, the deformable portion 101 has a first form and a second form. In the first form, the earphone 100 is in an in-ear mode, where at least a portion of the deformable portion 101 is located inside the wearer's ear canal. In the second form, the earphone 101 is in a bone conduction mode, where the entire deformable portion 101 is located outside the wearer's ear canal and conforms to the wearer's head, transmitting signals to the auditory nerve through the wearer's skull and cheekbone.

[0029] The first form of the deformable part 101 will be described below:

[0030] When the user needs to wear the in-ear headphones 100, the wearer manually adjusts the deformable part 101 to its first position. At this time, a sound outlet channel is formed inside the deformable part 101, and the two ends of the sound outlet channel are connected to the output end of the speaker unit 103 and the sound outlet 120, respectively. The wearer puts at least a part of the deformable part 101 into the ear canal, and the headphones 100 controls the speaker unit 103 to operate and emit sound. The sound emitted by the speaker unit 103 is transmitted to the sound outlet 120 through the sound outlet channel and then to the wearer's ear canal through the sound outlet 120.

[0031] The second form of the deformable part 101 will be described below:

[0032] When the user needs to wear the bone conduction headphones 100, the wearer manually adjusts the deformable part 101 to the second form, with the output ends of the bone conduction resonator unit 104 of the deformable part 101 distributed on the side of the deformable part 101. The wearer wears the deformable part 101 with the side fitting against the auricle. At this time, the speaker unit 103 is located at the wearer's mastoid bone, and the bone conduction resonator unit 104 fits against the wearer's head. The headphones 100 controls the speaker unit 103 and the bone conduction resonator unit 104 to emit sound synchronously. The speaker unit 103 and the bone conduction resonator unit 104 can drive the wearer's skull to vibrate, and transmit the sound directly to the auditory nerve.

[0033] For example, the bone conduction oscillator unit 104 can be a matrix micro bone conduction oscillator and a fixing bracket. The bone conduction oscillator unit 104 is embedded in the deformable part 101 and can deform with the deformation of the deformable part 101.

[0034] It should be noted that when the deformable part 101 is in the second form, the controller 122 can be selected to control the speaker unit 103 and the bone conduction oscillator unit 104 to operate simultaneously in order to increase the volume of the bone conduction mode.

[0035] For example, such as Figure 1 The first state shown includes a compressed state, such as Figure 2 The second form shown includes a stretched state. For example, when the deformable part 101 is in a stretched state, the deformable part 101 is cylindrical. When the deformable part 101 is in a compressed state, the middle part of the deformable part 101 extends in the radial direction, and the two ends of the deformable part 101 shorten in the axial direction.

[0036] In this embodiment, the earphone 100 includes a deformable portion 101 capable of deformation and an ear stem portion 102 connected to the deformable portion 101. A controller 122 is also provided in the ear stem portion 102. A speaker unit 103 and a bone conduction vibrator unit 104 are provided in the deformable portion 101. When the deformable portion 101 is in a first state, the controller 122 controls the speaker unit 103 to work, and sound can be transmitted outward through the sound outlet 120, so that the earphone 100 operates in the sound production mode of an in-ear earphone 100. When the deformable portion 101 is in a second state, the controller 122 controls the bone conduction vibrator unit 104 to work, and vibration can be transmitted to the wearer's skull through the deformable portion 101, so that the earphone 100 can operate in the sound production mode of a bone conduction earphone 100. This solves the problem of the single wearing mode of the earphone 100 and can meet the user's usage needs in different scenarios.

[0037] Figure 3 This shows one of the structural schematic diagrams of the deformable part 101 provided in some embodiments of this application. Figure 4 This is a second schematic diagram of the structure of the modified part 101 provided in some embodiments of this application, such as... Figure 3 and Figure 4 As shown, in some embodiments of this application, the number of bone conduction oscillator units 104 is multiple, and the modified portion 101 includes:

[0038] The flexible component 105 has multiple bone conduction resonator units 104 embedded within it, and a speaker unit 103 is disposed at one end of the flexible component 105 near the ear stem portion 102. When the deformable portion 101 is in a first state, the multiple bone conduction resonator units 104 are spaced apart on the flexible component 105. When the deformable portion 101 is in a second state, the multiple bone conduction resonator units 104 are clustered in a first region of the flexible component 105, which is used to fit against the wearer's ear.

[0039] In this embodiment, there are multiple bone conduction transducer units 104. When the deformable portion 101 is in the second form, the multiple bone conduction transducer units 104 operate synchronously, enabling the earphone 100 to operate in bone conduction mode. All the multiple bone conduction transducer units 104 are embedded inside the flexible component 105. The flexible component 105 can deform under force. By applying external force to the flexible component 105, the deformable portion 101 switches between the first and second forms. When the deformable portion 101 is in different deformed states, the multiple bone conduction transducer units 104 are located in different positions, allowing the earphone 100 to provide good sound quality and appropriate volume whether in an in-ear wearing mode or a bone conduction wearing mode.

[0040] The following instructions are for users wearing in-ear headphones:

[0041] When the user needs to wear the device in an in-ear manner, the user squeezes the flexible component 105, causing the flexible component 105 to be in a compressed state. The deformable part 101 is in the first form, that is, the deformable part 101 is in a compressed state, which makes it easy for the user to wear the deformable part 101 in the ear canal. At this time, since the bone conduction oscillator unit 104 does not need to operate, there is no need to adjust the position of the multiple bone conduction oscillator units 104 in the flexible component 105. Therefore, the multiple bone conduction oscillator units 104 are distributed at intervals in the flexible component 105.

[0042] The following explains the wearing method for users using bone conduction:

[0043] When the user needs to wear the headphones in a bone conduction mode, the user stretches the flexible component 105, so that the flexible component 105 is in a stretched state and the deformable part 101 is in a second form, that is, the deformable part 101 is in a stretched state, which makes it easier for the user to wear the deformable part 101 on the auricle. At this time, since the bone conduction vibrator unit 104 needs to work to produce sound, multiple bone conduction vibrator units 104 need to be driven to gather in the first area of ​​the flexible component 105, and the first area is in contact with the user's ear. When multiple bone conduction vibrator units 104 work, the headphones 100 can transmit sound to the user's auditory nerve through bone conduction, thereby improving the sound output effect of the headphones 100 in bone conduction mode.

[0044] In this embodiment, by providing a flexible component 105 in the deformable portion 101, multiple bone conduction oscillator units 104 are movably disposed inside the flexible component 105. When the deformable portion 101 is in the first state, the sound output effect of the earphone 100 in the in-ear wearing mode is improved, and when the deformable portion 101 is in the second state, the sound output effect of the earphone 100 in the bone conduction wearing mode is improved.

[0045] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the flexible component 105 includes: a first flexible structure 107 and a second flexible structure 108. The first flexible structure 107 is provided with a vibrator slide 114, and a plurality of bone conduction vibrator units 104 are slidably disposed in the vibrator slide 114, with a first region located at the end of the vibrator slide 114 away from the ear stem portion 102; the second flexible structure 108 is sleeved on the first flexible structure 107.

[0046] In this embodiment, the flexible component 105 includes a first flexible structure 107 and a second flexible structure 108 that are nested together. The first flexible structure 107 is located inside the second flexible structure 108, and both the first flexible structure 107 and the second flexible structure 108 are made of flexible material. By applying an external force to the first flexible structure 107 and the second flexible structure 108, both the first flexible structure 107 and the second flexible structure 108 can be deformed. An oscillator slide 114 is provided on the inner side of the first flexible structure 107, and a plurality of bone conduction oscillator units 104 are slidably disposed inside the oscillator slide 114. The second flexible structure 108 is sleeved on the outer side of the first flexible structure 107 to prevent the bone conduction oscillator units 104 from being exposed to the outside, thus protecting the first flexible structure 107 and the bone conduction oscillator units 104. One end of the first flexible structure 107 and the second flexible structure 108, which are interlocked, is connected to the ear stem portion 102. When the deformable portion 101 is in the second form, the first area where multiple bone conduction oscillator units 104 are gathered is the other end of the first flexible structure 107.

[0047] For example, the first flexible structure 107 is a flexible tube, the second flexible structure 108 is also a flexible tube, and the vibrator slide 114 is disposed on the inner sidewall of the first flexible structure 107.

[0048] For example, the number of oscillator slides 114 can be multiple or one. When there are multiple oscillator slides 114, the multiple oscillator slides 114 are distributed along the periphery of the first flexible structure 107, and each oscillator slide 114 extends along the axial direction of the first flexible structure 107. Figure 2 and Figure 3 The middle arrow A indicates the axial direction. For example, there are N oscillator slides 114, M bone conduction oscillator units 104, and P bone conduction oscillator units 104 in each oscillator slide 114, where N = M × P, and N, M, and P are all positive integers.

[0049] It should be noted that when the deformable part 101 is in the first state, the flexible component 105 is in a compressed state. The deformable part 101 in the compressed state is shorter, and its middle portion protrudes. Inserting the deformable part 101 into the wearer's ear canal in this state increases the friction between the deformable part 101 and the ear canal, preventing it from falling out. When the deformable part 101 is in the second state, the flexible component 105 is in a stretched state. The deformable part 101 in the stretched state is longer, and it can deform, making it easier for the user to bend and wear it around the ear.

[0050] In this embodiment, the deformable part 101 is provided with a first flexible structure 107 and a second flexible structure 108 that are nested together. A vibrator slide 114 is provided in the first flexible structure 107 so that the bone conduction vibrator unit 104 can slide in the vibrator slide 114. After the wearer adjusts the shape of the deformable part 101, the bone conduction vibrator unit 104 can also be driven to slide in the vibrator slide 114, thereby adjusting the position of the bone conduction vibrator unit 104 in the deformable part 101, further improving the audio output effect of the earphone 100 in bone conduction mode.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the deformable part 101 further includes a driving component 106 connected to the first flexible structure 107. The driving component 106 is used to drive a plurality of bone conduction oscillator units 104 to slide within the oscillator slide rail 114.

[0052] In this embodiment of the application, by providing a driving component 106 in the deformable part 101, and the driving end of the driving component 106 being in contact with the bone conduction oscillator unit 104, the user can drive the position of multiple bone conduction oscillator units 104 in the flexible component 105 through the driving component 106.

[0053] For example, the drive component 106 can be a lead screw structure, which drives the flexible tube to switch between a stretched state and a compressed state.

[0054] It should be noted that the deformation state of the deformable part 101 does not need to be adjusted by the drive component 106. Since the flexible component 105 in the deformable part 101 is a flexible material structure, the user can directly stretch or compress the flexible component 105 to make it in the corresponding deformation state. When the deformable part 101 is in the second form, in order to position the multiple bone conduction resonator units 104 in the first area that fits the user's ear, the user manually operates the drive component 106 to adjust the position of the multiple bone conduction resonator units 104, further improving the sound output effect of the headphones 100 in bone conduction mode.

[0055] Figure 5 The diagram shows a structural schematic of the first pipe fitting 109 provided in some embodiments of this application. Figure 6 The following is a schematic diagram of the structure of the second pipe fitting 111 provided in some embodiments of this application. Figure 7 The third schematic diagram shows the structure of the modified part 101 provided in some embodiments of this application, such as... Figures 3 to 7 As shown, in some embodiments of this application, the inner wall of the first flexible structure 107 is provided with a motion track 121, and the drive assembly 106 includes: a first tube 109 and a second tube 111. The first tube 109 is disposed within the first flexible structure 107 and is rotatably connected to the first flexible structure 107, and the first tube 109 is provided with a guide groove 110; the second tube 111 passes through the first tube 109, and the outer wall of the second tube 111 is provided with a guide portion 112 and a pushing portion 113. The guide portion 112 passes through the guide groove 110 and is in contact with the motion track 121, wherein the pushing portion 113 is used to push multiple bone conduction oscillator units 104 to slide within the oscillator slide 114.

[0056] In this embodiment, the drive assembly 106 includes a first tube 109 and a second tube 111. The first tube 109 is disposed inside the first flexible structure 107 and is rotatable relative to the first flexible structure 107. The outer wall of the second tube 111 is provided with a guide portion 112 and a push portion 113. The guide portion 112 and the push portion 113 are respectively located at both ends of the outer wall of the second tube 111. The guide portion 112 is located in the guide groove 110 of the first tube 109 and can slide within the guide groove 110. The guide portion 112 is in contact with the motion track 121, that is, the motion track 121 can limit the sliding of the guide portion 112 relative to the guide groove 110, so that the guide portion 112 can drive the second tube 111 to slide axially relative to the first flexible structure 107 under the combined action of the motion track 121 and the guide portion 112, thereby causing the push portion 113 to push the bone conduction oscillator unit 104 to slide within the oscillator slide rail 114.

[0057] like Figure 3 As shown, when the deformable part 101 is in the first form, the second tube 111 is located inside the first tube 109, and the bone conduction oscillator unit 104 is distributed in the oscillator slide 114.

[0058] like Figure 4 As shown, when the deformable part 101 is in the second form, the first tube 109 is rotated, and the second tube 111 moves to the right along the axial direction of the first flexible structure 107 under the action of the guide part 112, the guide groove 110 and the motion track 121, until the bone conduction oscillator unit 104 is pushed to the right side of the deformable part 101.

[0059] It should be noted that the first tube 109 in the drive assembly 106 can be set at the first end or the second end of the first flexible structure 107. The first end of the first flexible structure 107 is the end near the sound outlet 120, and the second end of the first flexible structure 107 is the end near the first sound-emitting element.

[0060] In this embodiment, the drive assembly 106 includes a first tube 109 and a second tube 111. The guide portion 112 in the second tube 111 can drive the push portion 113 of the second tube 111 to push the bone conduction oscillator unit 104 to slide in the oscillator slide 114 under the action of the guide groove 110 of the first tube 109 and the movement track 121 of the first flexible structure 107, so that the wearer can adjust the position of the bone conduction oscillator unit 104 in the deformation portion 101 according to actual needs.

[0061] like Figure 5As shown, in some embodiments of this application, the guide groove 110 includes: a first sub-groove 115 and a second sub-groove 116. The first sub-groove 115 extends along the axial direction of the first pipe 109, and the second sub-groove 116 is connected to the first sub-groove 115 and extends along the axial direction of the first pipe 109.

[0062] In this embodiment, the first sub-slide groove 115 is a through groove provided on the first pipe 109. The first pipe 109 is coaxially arranged with the flexible pipe. The first sub-slide groove 115 is arranged to be distributed along the axial direction of the first pipe 109 on the side wall of the first pipe 109. The first sub-slide groove 115 can limit the sliding of the second driving member along the axial direction of the flexible pipe, and prevent the second driving member from moving circumferentially along the flexible pipe.

[0063] In this embodiment, the second sub-slide 116 is also a through groove provided on the first tube 109. The second sub-slide 116 is a limiting groove. The second sub-slide 116 is distributed along the axial direction of the first tube 109. When the first tube 109 rotates to a certain extent, the guide part 112 of the second drive tube slides from the first sub-slide 115 to the second sub-slide 116 to avoid excessive rotation of the first tube 109, which would cause the push part 113 to over-compress and damage the bone conduction vibrator unit 104.

[0064] For example, there are two second sub-slides 116, and the two second sub-slides 116 are located at both ends of the first sub-slide 115.

[0065] In some embodiments of this application, the earphone 100 may optionally include a flexible connector 117, the first end of which is connected to the ear stem portion 102, and the second end of which is connected to the deformable portion 101.

[0066] In this embodiment, the earphone 100 further includes a flexible connector 117, which is disposed between the ear stem portion 102 and the deformable portion 101. The flexible connector 117 can deform under the action of external force. When the wearer wears the earphone 100, the wearer can apply external force to the deformable portion 101 and the flexible connector 117 according to actual needs to change the shape of the flexible connector 117 and the deformable portion 101, so that the earphone 100 is more suitable for the wearer's wearing position.

[0067] It should be noted that a power supply module is provided inside the ear stem 102. The power supply module is electrically connected to the speaker unit 103 and the bone conduction resonator unit 104. The power supply module can supply power to the speaker unit 103 and the bone conduction resonator unit 104.

[0068] Figure 8The fourth schematic diagram of the structure of the modified part 101 provided in some embodiments of this application is shown, such as Figure 8 As shown, in some embodiments of this application, the deformed part 101 further includes a magnetic shielding member 118, one end of which is connected to the flexible tube and the other end of which is connected to the speaker unit 103.

[0069] In this embodiment, the deformable portion 101 further includes a magnetic shielding member 118, which is disposed between the flexible tube and the speaker unit 103, i.e., the speaker unit 103 is connected to the flexible tube through the magnetic shielding member 118. Since the bone conduction resonator unit 104 includes multiple bone conduction resonators, and the multiple bone conduction resonators are disposed inside the flexible tube, the magnetic shielding member 118 isolates the flexible tube from the speaker unit 103, thus preventing mutual interference between the speaker unit 103 and the bone conduction resonator unit 104 during operation.

[0070] For example, the magnetic shielding element 118 may be magnetic shielding foam.

[0071] like Figure 8 As shown, in some embodiments of this application, the earphone 100 further includes a Hall sensor 119 disposed on the deformable part 101. The Hall sensor 119 is used to acquire distance information between the Hall sensor 119 and the speaker unit 103, and transmit the distance information to the controller 122 so that the controller 122 determines whether the deformable part 101 is in a first form or in a second form based on the distance information.

[0072] In this embodiment, the earphone 100 further includes a Hall sensor 119, which is disposed within the deformable portion 101, specifically embedded within the flexible material of the deformable portion 101. When the wearer stretches or squeezes the deformable portion 101, the distance between the Hall sensor 119 and the speaker unit 103 changes. Since the speaker unit 103 includes a magnet, the voltage of the Hall sensor 119 also changes with the distance. The earphone 100 can determine the distance between the Hall sensor 119 and the speaker unit 103 by the voltage value of the Hall sensor 119, thus determining the shape of the earphone 100. This allows the earphone 100 to automatically detect the operating mode required by the wearer and automatically control the operating state of the speaker unit 103 and the bone conduction resonator unit 104.

[0073] Specifically, the distance information is the voltage value output by the Hall sensor 119. The Hall sensor 119 transmits the voltage value to the controller 122 so that the controller 122 can determine whether the deformable part 101 is currently in the first state or in the second state.

[0074] In this embodiment, by setting a Hall sensor 119 inside the earphone 100, the earphone 100 can automatically detect the deformation state of the deformable part 101, and control the operating state of the speaker unit 103 and the bone conduction resonator unit 104 based on the automatic detection result, without requiring the user to manually adjust the operating state of the speaker unit 103 and the bone conduction resonator unit 104, thus improving the convenience of using the earphone 100.

[0075] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the deformable portion 101 is provided with a sound outlet 120 at the end away from the ear stem portion 102.

[0076] In this embodiment, the deformable part 101 is connected to the ear stem part 102. A sound outlet 120 is provided at the end of the deformable part 101 away from the ear. When the deformable part 101 is in the first state, the deformable part 101 can be worn in the user's ear canal. The speaker unit 103 operates and transmits audio to the user's ear canal through the sound outlet 120, thereby improving the sound output effect of the earphone 100 in the in-ear wearing mode.

[0077] In some embodiments of this application, a method for controlling headphones is provided, applicable to the headphones in any of the above embodiments. Figure 9 The following is a flowchart illustrating the headphone control method provided in some embodiments of this application, such as... Figure 9 As shown, the headphone control method includes:

[0078] Step 902: Obtain the deformation state of the deformed part;

[0079] In this embodiment, the earphone includes a deformable portion, on which a speaker unit, a bone conduction transducer unit, and a sound outlet are disposed. The speaker unit and the sound outlet are located at both ends of the deformable portion. The deformable portion is a flexible component, capable of deforming under stress.

[0080] Step 904: When the deformable part is in the first state, control the speaker unit to work;

[0081] Step 906: When the deformed part is in the second state, control the bone conduction oscillator unit to work.

[0082] In this embodiment, the deformable part of the earphone is in different forms under different operating modes. Specifically, the deformable part has a first form and a second form. In the first form, the earphone is in an in-ear mode, at least a portion of the deformable part is located inside the wearer's ear canal. In the second form, the earphone is in a bone conduction mode, the entire deformable part is located outside the wearer's ear canal, and the deformable part is in contact with the wearer's head, transmitting signals to the auditory nerve through the wearer's skull and cheekbone. The first form of the deformable part is described below:

[0083] When a user needs to wear in-ear headphones, the wearer manually adjusts the deformable part to its first position. At this time, a sound outlet channel is formed inside the deformable part, and the two ends of the sound outlet channel are connected to the output end of the speaker unit and the sound outlet hole, respectively. The wearer puts at least a part of the deformable part into the ear canal, and the headphones control the speaker unit to operate and produce sound. The sound emitted by the speaker unit is transmitted through the sound outlet channel to the sound outlet hole, and then through the sound outlet hole to the wearer's ear canal.

[0084] For example, the speaker unit can be a speaker, or it can be a bone conduction vibrator and a fixed bracket. When the deformable part is in the first form, the audio generated by the speaker unit can be transmitted to the sound outlet through the sound outlet channel.

[0085] The first form of the deformed part is described below:

[0086] When a user needs to wear bone conduction headphones, the wearer manually adjusts the deformable part to the second configuration. The output terminals of the bone conduction transducer units in the deformable part are distributed on the side of the deformable part. The wearer then places the deformable part against the ear. At this time, the speaker unit is located at the wearer's mastoid bone, and the bone conduction transducer units are in contact with the wearer's head. The headphones control the bone conduction transducer units to produce sound, or control the speaker unit and bone conduction transducer units to produce sound synchronously. The speaker unit and bone conduction transducer units can drive the wearer's skull to vibrate, and the sound is directly transmitted to the auditory nerve.

[0087] In this embodiment, the earphone includes a deformable part that can deform, and an ear stem connected to the deformable part. A controller is also provided in the ear stem. A speaker unit and a bone conduction vibrator unit are provided in the deformable part. When the deformable part is in a first state, the controller controls the speaker unit to work, and the sound can be transmitted outward through the sound outlet, so that the earphone operates in the sound production mode of an in-ear earphone. When the deformable part is in a second state, the controller controls the bone conduction vibrator unit to work, and the vibration can be transmitted to the wearer's skull through the deformable part, so that the earphone operates in the sound production mode of a bone conduction earphone. This solves the problem of the single wearing mode of the earphone and can meet the user's usage needs in different scenarios.

[0088] Optionally, in some embodiments of this application, the earphone further includes a Hall sensor disposed on the deformable portion, which acquires the shape of the deformable portion including:

[0089] The voltage value at the Hall sensor is acquired; the target distance value is determined based on the voltage value, and the target distance value is the distance between the Hall sensor and the speaker unit; if the target distance value is within a first distance value range, the deformable part is determined to be in a first form; if the target distance value is within a second distance value range, the deformable part is determined to be in a second form.

[0090] In this embodiment, the earphone also includes a Hall sensor, which is disposed within the deformable portion, specifically embedded in the flexible material of the deformable portion. When the wearer stretches or squeezes the deformable portion, the distance between the Hall sensor and the speaker unit changes. Since the speaker unit includes a magnet, the voltage of the Hall sensor also changes with the distance. The earphone can determine the target distance between the Hall sensor and the speaker unit through the voltage value of the Hall sensor, determine the shape of the earphone, and enable the earphone to automatically detect the operating mode required by the wearer, thereby automatically controlling the operating state of the speaker unit and the bone conduction transducer unit.

[0091] In this embodiment, there is no overlap between the first distance range and the second distance range, and the first distance range and the second distance range are related to the setting position of the Hall sensor.

[0092] For example, the minimum value of the first distance range is greater than the maximum value of the second distance range. When the Hall sensor is far from the speaker unit, the earphone is determined to be in in-ear mode, i.e., the deformable part is in the first form. When the Hall sensor is close to the speaker unit, the earphone is determined to be in bone conduction mode, i.e., the deformable part is in the second form.

[0093] For example, the maximum value of the first distance range is less than the minimum value of the second distance range. When the Hall sensor is close to the speaker unit, the earphone is determined to be in in-ear mode, i.e., the deformable part is in the first form. When the Hall sensor is far from the speaker unit, the earphone is determined to be in bone conduction mode, i.e., the deformable part is in the second form.

[0094] It should be noted that a Hall sensor is a sensor for detecting magnetic fields and generates a corresponding voltage value based on the detected magnetic field. Therefore, by obtaining the voltage value of the Hall sensor, the target distance between the acquisition device and the speaker unit can be determined.

[0095] The Hall sensor operates based on the Hall effect, which occurs when a conductor carrying current is placed in a magnetic field, creating a transverse voltage difference. This voltage difference is called the Hall voltage. When the Hall sensor is placed in a magnetic field, if current flows through it, a potential difference is generated perpendicular to both the current direction and the magnetic field direction due to the Hall effect. This potential difference is also called the Hall voltage, and its magnitude is proportional to the current and the magnitude and direction of the magnetic field. By measuring the Hall voltage, i.e., the voltage value of the Hall sensor, the strength and direction of the magnetic field can be determined, thereby determining the target distance between the Hall sensor and the magnet.

[0096] Figure 10 The following are control schematic diagrams of the speaker unit and bone conduction resonator unit provided in some embodiments of this application, such as... Figure 10 As shown, the power supply powers the Hall sensor through the processor, and drives the speaker unit to produce sound through the first power amplifier based on the voltage value at the Hall device, and drives the bone conduction transducer unit to produce sound through the second power amplifier.
