[0003] At present, when users use smart head-mounted devices to listen to music, they not only have higher and higher requirements for sound quality, but also hope to enjoy various sound qualities anytime and anywhere. However, existing smart head-mounted devices can only meet the user's listening needs when they are worn by the user and when the smart head-mounted devices are close to the user's ears. When the smart head-mounted device is separated from the human body and is not worn, it cannot meet the user's listening needs, which greatly limits the use scenarios of smart head-mounted devices and also reduces the user's experience.

[0036] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0039] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] refer to Figure 1-Figure 4 As shown, according to an embodiment of the present application, a head mounted device is provided, the head mounted device comprising a shell 1, a sound generating device 2, a bone conduction vibrator 3 and a main processor, the shell 1 having a first surface 101; generally speaking, when the head mounted device is in a wearing state, the first surface 101 is the upper surface of the shell 1; the sound generating device 2 is arranged on the shell 1; the bone conduction vibrator 3 is arranged on the shell 1, the bone conduction vibrator 3 and the sound generating device 2 are both electrically connected to the main processor; the bone conduction vibrator 3 has a vibration surface 301;

[0042] When the head mounted device is in a wearing state, the main processor controls the sound emitting device 2 to radiate a first sound wave outward;

[0043] When the head-mounted device is in a non-wearing state and the head-mounted device is placed on the external carrier 01 with the first surface 101 facing the external carrier 01, the vibration surface 301 of the bone conduction vibrator 3 is in contact with the external carrier 01, specifically, the vibration surface 301 is arranged flush with the first surface 101 or the vibration surface 301 protrudes from the first surface 101; the main processor controls the bone conduction vibrator 3 to radiate a second sound wave outward, the second sound wave drives the vibration surface 301 to vibrate, and the vibration surface 301 drives the external carrier to resonate.

[0044] The head-mounted device provided in the embodiment of the present application can achieve the sound-generating effect in two usage scenarios: in the first usage scenario, the head-mounted device is in a wearing state, that is, the user wears the head-mounted device on the head, and the sound-generating device 2 is located close to the human ear. Generally speaking, the distance between the sound-generating device and the ear entrance of the human ear is about 0.03m-0.05m, so that a sound pressure level of about 80dBSPL can be generated at the eardrum of the ear, thereby meeting the listening needs of the human ear. In the first usage scenario, the sound-generating device 2 emits a first sound wave, which is received by the user's ear, thereby meeting the user's listening needs.

[0045] In the second usage scenario, the head-mounted device is in a non-wearing state, that is, the head-mounted device is separated from the user's head, and the user can place the head-mounted device on an external carrier 01, such as a desktop or other flat surface; and when the head-mounted device is placed on the external carrier 01, the vibration surface 301 of the bone conduction vibrator 3 abuts against the external carrier 01. In the second usage scenario, the bone conduction vibrator 3 emits a second sound wave, which drives the vibration surface 301 to vibrate, and the vibration surface 301 further drives the external carrier 01 to resonate, thereby amplifying the sound, so that the head-mounted device can also meet the user's listening needs when it is not worn.

[0046] Generally speaking, when using a speaker for listening, the speaker needs to generate a sound pressure level of about 80dBSPL at the eardrum at a distance of 0.5m-1m from the ear, so conventional wearable devices cannot achieve the function of a speaker. The head-mounted device provided in the embodiment of the present application not only has the functions of a conventional head-mounted device, but also can play a role similar to a speaker when the user is not wearing the head-mounted device, meeting the user's various listening needs and improving the user's experience.

[0047] Furthermore, the driving mode of the sound-generating device 2 may be a moving coil type, a moving iron type, etc. The sound outlet of the sound-generating device 2 is opened on the first surface 101 .

[0048] In one embodiment, the head-mounted device also includes a material identification module, which is electrically connected to the main processor; when the vibration surface 301 of the bone conduction vibrator 3 is in contact with the external carrier 01, the material identification module identifies the material of the external carrier 01 and outputs an identification signal, and the main processor receives the identification signal and adjusts the vibration frequency of the bone conduction vibrator 3 according to the identification signal so that the vibration frequency of the bone conduction vibrator 3 matches the natural frequency of the external carrier 01.

[0049] Since external carriers 01 made of different materials have different natural frequencies, the vibration frequencies required to cause external carriers 01 made of different materials to resonate are different. Therefore, in this specific example, in order to allow the bone conduction vibrator 3 to resonate on an external carrier 01 made of any material, a material identification module is set to identify the specific material of the external carrier 01, and according to the identification result, the vibration frequency of the bone conduction vibrator 3 is adjusted through the control of the main processor to match the vibration frequency of the bone conduction vibrator 3 with the natural frequency of the external carrier 01; the matching means that the vibration frequency of the bone conduction vibrator 3 is adjusted to be the same as the natural frequency of the external carrier 01, thereby ensuring that the vibration of the bone conduction vibrator 3 can cause the external carrier 01 to resonate.

[0050] In one embodiment, the material identification module includes an infrared spectrum sensor.

[0051] In this specific example, an infrared spectrum sensor is used to automatically identify the material of the external carrier 01, and the main processor automatically adjusts the vibration frequency of the bone conduction vibrator 3 according to the identification result of the infrared spectrum sensor.

[0052] In other examples, the material of the external carrier 01 can be identified by manual identification, and then the user can adjust the vibration frequency of the bone conduction vibrator 3 using a mobile phone app according to the identification result. Figure 2 As shown, an adjustment area A for adjusting the vibration frequency of the bone conduction vibrator 3 may also be provided on the head mounted device. After the material of the external carrier 01 is manually identified, the vibration frequency of the bone conduction vibrator 3 may be adjusted directly through the adjustment area A.

[0053] Adjusting the vibration frequency of the bone conduction vibrator 3 can be achieved, for example, by adjusting the magnitude of the current input to the bone conduction vibrator 3: when the current input to the bone conduction vibrator 3 increases, the vibration frequency of the bone conduction vibrator 3 increases; when the current input to the bone conduction vibrator 3 decreases, the vibration frequency of the bone conduction vibrator 3 decreases.

[0054] Reference Figure 1 , Figure 4As shown, in one embodiment, the head-mounted device also includes a first vibration transmission layer 4, which is connected to the vibration surface 301. When the head-mounted device is placed on the external carrier 01 with the first surface 101 facing the external carrier 01, the vibration surface 301 of the bone conduction vibrator 3 is in contact with the external carrier 01 through the first vibration transmission layer 4.

[0055] In this specific example, the provision of the first vibration transmission layer 4 can improve the tightness of the contact between the bone conduction vibrator 3 and the external carrier 01. The vibration surface 301 of the bone conduction vibrator 3 can be tightly fitted with the external carrier 01 through the first vibration transmission layer 4, thereby improving the effect of the bone conduction vibrator 3 driving the external carrier 01 to vibrate together.

[0056] Further, the first vibration transmission layer 4 can be a rubber layer or a gel layer. For example, the first vibration transmission layer 4 can be a soft rubber layer, or a gel patch, or a rubber suction cup.

[0057] Reference Figure 4 As shown, in one embodiment, the head mounted device further comprises a second vibration transmission layer 5, and the second vibration transmission layer 5 is connected to the vibration surface 301, and when the head mounted device is in a worn state, the second vibration transmission layer 5 abuts against the wearer's head.

[0058] In this specific example, by providing a second vibration transmission layer 5, when the head mounted device is worn by a user, the second vibration transmission layer 5 abuts against the wearer's head. Thus, the user can not only listen to the sound emitted by the sound generating device 2 directly into the ear, but also listen to the sound through the bone conduction vibrator 3 in cooperation with the second vibration transmission layer 5 in a bone conduction sound transmission manner, thereby playing a role in supplementing the sound.

[0059] In one embodiment, the head mounted device further includes a pressure sensor, which is disposed close to the bone conduction vibrator 3; the pressure sensor is electrically connected to the main processor.

[0060] In this specific example, a sensor, such as a pressure sensor, is provided near the position where the bone conduction vibrator 3 is located. When the user's finger presses this position, the pressure sensor can transmit the finger's pressing information to the main processor. Therefore, when the head-mounted device is in the wearing state, the human ear receives the call sound or the music playing sound through the sound-generating device 2, and at this time, the bone conduction vibrator 3 can play the role of tactile feedback. Specifically: for example, when answering a call, the user's finger presses the position where the bone conduction vibrator 3 is located. Since a pressure sensor is provided near this position, the pressure sensor transmits the finger's pressing signal to the main processor, so the main processor processes the call-connecting instruction, and then sends the successfully processed instruction to the bone conduction vibrator 3. At this time, the bone conduction vibrator 3 will vibrate to give the user's finger a vibration feedback, so that the user can feel that the call has been connected through the vibration tactile sense of the finger.

[0061] In one embodiment, the head mounted device further includes an acceleration sensor, and the acceleration sensor is electrically connected to the main processor.

[0062] In this specific example, when the head-mounted device is in a non-wearing state, if the user still wants to enjoy music through the head-mounted device, the head-mounted device can be turned upside down. The turning upside down means that when the head-mounted device is in a wearing state, the upper surface of the shell 1, that is, the first surface 101, is placed in a downward posture, so that the vibration surface 301 of the bone conduction vibrator 3 can be in contact with the external carrier 01 such as a desktop. The acceleration sensor can sense that the head-mounted device is turned upside down, and at this time the bone conduction vibrator 3 is in a music playing state. Specifically, when the bone conduction vibrator 3 is turned on for music playing, the sound is played out through the bone conduction vibrator 3 in cooperation with the external carrier, that is, the sound emitted by the bone conduction vibrator 3 is amplified by the external carrier 01 in contact with it.

[0063] Reference Figure 1 As shown, in one embodiment, a mounting groove 11 is provided on the housing 1 , and the bone conduction vibrator 3 is arranged in the mounting groove 11 .

[0064] In this specific example, a mounting groove 11 is provided on the housing 1 to mount the bone conduction vibrator 3 , and the bone conduction vibrator 3 is embedded in the mounting groove 11 to improve the stability of the bone conduction vibrator 3 on the housing 1 .

[0065] Reference Figure 1 , Figure 2 As shown, in one embodiment, the head mounted device includes two shells 1 , and each shell 1 is provided with a sound emitting device 2 and a bone conduction vibrator 3 .

[0066] When the head-mounted device is worn by a user, the housing 1 is hung on the user's ear; that is, for smart glasses, the housing 1 corresponds to the temples of the smart glasses, and the sound-generating device 2 and the bone conduction vibrator 3 are arranged on both the left and right temples to improve the listening effect of the head-mounted device. Furthermore, the head-mounted device also includes a frame 6 arranged between the two housings 1.

[0067] According to another embodiment of the present application, a method for controlling a head mounted device is provided, the method comprising:

[0068] When the head mounted device is in a wearing state, the main processor sends a first instruction to the sound emitting device 2, and the sound emitting device 2 receives the first instruction and radiates a first sound wave outward according to the first instruction;

[0069] When the head mounted device is in a non-wearing state, the main processor sends a second instruction to the bone conduction vibrator 3, the bone conduction vibrator 3 receives the second instruction and radiates a second sound wave outward according to the second instruction, the second sound wave drives the vibration surface 301 to vibrate, and the vibration surface 301 drives the external carrier to resonate.

[0070] The control method of the head mounted device provided in the embodiment of the present application can realize the sound-generating effect of the head mounted device in two usage scenarios:

[0071] In the first usage scenario, the head mounted device is in a wearing state, that is, the user wears the head mounted device on the head. At this time, the sound emitting device 2 radiates the first sound wave outward according to the first instruction issued by the main processor, and the human ear receives the first sound wave to meet the listening needs.

[0072] In the second usage scenario, the head-mounted device is in a non-wearing state, that is, the head-mounted device is detached from the user's head, and the user can place the head-mounted device on an external carrier 01, such as a desktop or other flat surface; at this time, the bone conduction vibrator 3 radiates a second sound wave outward according to the second instruction issued by the main processor, and the second sound wave drives the vibration surface 301 to vibrate, and the vibration surface 301 then drives the external carrier to resonate, thereby achieving the purpose of emitting sound outward.

[0073] In one embodiment, the head mounted device further comprises a material identification module, and the material identification module is electrically connected to the main processor;

[0074] When the head mounted device is in a non-wearing state, before the main processor sends a second instruction to the bone conduction vibrator 3, the method further includes:

[0075] The material identification module identifies the material of the external carrier and outputs an identification signal, and the main processor receives the identification signal and adjusts the vibration frequency of the bone conduction vibrator 3 according to the identification signal so that the vibration frequency of the bone conduction vibrator 3 matches the natural frequency of the external carrier.

[0076] In this specific example, a material identification module is provided to identify the material of the external carrier 01, and according to the identification result, the vibration frequency of the bone conduction vibrator 3 is adjusted through the control of the main processor so that the vibration frequency of the bone conduction vibrator 3 matches the natural frequency of the external carrier 01; the matching means that the vibration frequency of the bone conduction vibrator 3 is adjusted to be the same as the natural frequency of the external carrier 01, thereby ensuring that the vibration of the bone conduction vibrator 3 can cause the external carrier 01 to resonate.
