[0052] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0053] Example 1

[0054] To facilitate understanding of this application, Figure 1 The flowchart of a volume adjustment method provided in the first embodiment of the present invention is shown to describe the content of the first embodiment of the present application in detail.

[0055] See also Figure 1 As stated, Figure 1 A flow chart of a volume adjustment method provided in a first embodiment of the present invention is shown. The volume adjustment method is applied to a volume adjustment system. The volume adjustment system includes a processor, a speaker, and a sensor. The processor is electrically connected to the speaker and the sensor, respectively. The sensor is disposed at a position capable of contacting a user's ear and is in the shape of a bar. The method includes steps S101 to S104:

[0056] S101: The sensor sends contact position information of the contact point between the user's ear and the sensor on the sensor to the processor.

[0057] Specifically, the sensor is a strip sensor having two short sides (a first short side and a second short side) and two long sides (a first long side and a second long side). The sensor is placed horizontally, and the first long side and the second long side of the sensor are parallel to the ground.

[0058] When the user's ear contacts the sensor and a contact point appears, the sensor sends contact position information, that is, a first distance between the contact point and the first short side of the sensor, and a second distance between the contact point and the second short side of the sensor to the processor.

[0059] S102: The processor determines the distance between the contact point and the speaker according to the contact position information and pre-stored relative position information of the speaker relative to the sensor.

[0060] Specifically, the position of the speaker setting satisfies that it is on the same side of the two short sides of the sensor. The relative position information of the speaker relative to the sensor includes relative distance information and relative direction information. The relative distance information is the distance between the short side of the sensor closest to the speaker and the speaker. The relative direction information is the angle between the line between the midpoint of the short side of the sensor closest to the speaker and the speaker and the long side of the sensor (that is, the horizontal direction).

[0061] For example, when the first short side of the sensor is closest to the speaker, the relative distance information is the first relative distance between the first short side and the speaker, and the relative direction information is the first angle between the line connecting the speaker and the midpoint of the first short side and the long side of the sensor. When the second short side of the sensor is closest to the speaker, the relative distance information is the second relative distance between the second short side and the speaker, and the relative direction information is the second angle between the line connecting the speaker and the midpoint of the second short side and the long side of the sensor.

[0062] When determining the distance between the contact point and the speaker, the following two situations are included:

[0063] Case 1: When the first short side of the sensor is closest to the speaker, the distance a between the contact point and the speaker is calculated according to the following formula:

[0064]

[0065] Wherein, b is the first distance in step S101, c is the first relative distance, and A is the first angle.

[0066] Case 2: When the second short side of the sensor is closest to the speaker, the distance x between the contact point and the speaker is calculated according to the following formula:

[0067]

[0068] Wherein, y is the second distance in step S101, z is the second relative distance, and x is the second angle.

[0069] S103: The processor determines the target playback power of the speaker from a preset playback power relationship table according to the distance.

[0070] Specifically, the preset playback power relationship table records at least one spacing value and at least one playback power value of a speaker, each spacing value has a corresponding playback power value of the speaker, and the playback power value indicates that when the speaker plays sound at the power value, the human ear can receive the most appropriate volume at the corresponding spacing value from the speaker; because the greater the distance between the speaker and the contact point (ear), the louder the sound played by the speaker is, and the louder the volume played by the speaker is, the greater the playback power value of the speaker is required, so the spacing value in the preset playback power relationship table is directly proportional to the playback power value, that is, the larger the spacing value, the larger the corresponding playback power value.

[0071] When the processor determines the target playback power of the speaker from a preset playback power relationship table based on the spacing, the processor traverses all spacing values ​​in the playback power relationship table and determines the playback power value that has a corresponding relationship with the spacing value that is the same as the spacing determined in step S102 as the target playback power of the speaker.

[0072] S104: The processor adjusts the playback power of the speaker according to the target playback power, so that the speaker can perform sound broadcasting at the target playback power.

[0073] Specifically, the processor controls the loudspeaker to broadcast the sound at the target playback power, so that the volume of the sound received by the human ear at the contact point is the volume that the loudspeaker can produce at the target playback power.

[0074] In one possible embodiment, see Figure 2 As shown, Figure 2 A flowchart of a playback power adjustment method provided in the first embodiment of the present invention is shown. After the processor adjusts the playback power of the speaker according to the target playback power, the method includes steps S201 to S202:

[0075] S201: The processor responds to a volume adjustment instruction issued by the user, compares the target playback power with the maximum playback power to obtain a comparison result, wherein the target playback power is the playback power at which the speaker broadcasts sound at the volume indicated by the volume adjustment instruction, the maximum playback power is the playback power at which the speaker broadcasts sound at the target maximum broadcast volume, and the target maximum broadcast volume is the volume determined by the processor from a preset maximum volume relationship table according to the spacing.

[0076] Specifically, since the human ear will be damaged after receiving sound with a volume exceeding a certain limit, in order to ensure that the volume of the sound emitted by the speaker does not exceed the volume that is harmful to the human ear when it reaches the human ear, it is necessary to compare the playback power of the speaker corresponding to the volume indicated by the volume adjustment instruction with the maximum playback power after the processor receives a volume adjustment instruction issued by the user to adjust the volume of the sound broadcast from the speaker, so as to determine whether the volume of the sound broadcast by the speaker at the playback power corresponding to the volume adjustment instruction will cause damage to the human ear; the target maximum broadcast volume is the boundary volume value broadcast by the speaker that does not cause damage to the human ear and causes damage. When the volume of the sound broadcast by the speaker is less than or equal to the target maximum volume, it does not cause damage to the human ear. When the volume of the sound broadcast by the speaker is greater than the target maximum volume, it causes damage to the human ear.

[0077] S202: The processor adjusts the current playback power of the speaker according to the comparison result, so that the speaker can perform sound broadcasting at the adjusted playback power.

[0078] Specifically, the processor adjusts the current playback power of the speaker in real time according to the comparison result, so that the sound broadcast by the speaker will not cause damage to the user's ears.

[0079] In one possible embodiment, see Figure 3 As shown, Figure 3 A flowchart of a specific method for adjusting playback power provided in the first embodiment of the present invention is shown, wherein the processor adjusts the current playback power of the speaker according to the comparison result, including steps S301 to S302:

[0080] S301: When the comparison result shows that the target playback power does not exceed the maximum playback power, the processor adjusts the playback power of the speaker to the target playback power.

[0081] Specifically, when the comparison result shows that the target playback power does not exceed the maximum playback power, it means that when the speaker broadcasts at the target playback power, the broadcast sound will not cause damage to the human ear, so the playback power of the speaker can be adjusted to the target playback power according to user needs.

[0082] S302: When the comparison result shows that the target playback power exceeds the maximum playback power, the processor adjusts the playback power of the speaker to the maximum playback power.

[0083] Specifically, when the comparison result shows that the target playback power exceeds the maximum playback power, it means that when the speaker broadcasts at the target playback power, the sound broadcast will cause damage to the human ear, so the playback power of the speaker is adjusted to the target playback power to ensure that the human ear will not be damaged due to the excessive volume received.

[0084] In a feasible implementation manner, when the comparison result shows that the target playback power exceeds the maximum playback power, the method further includes:

[0085] The processor broadcasts the preset alarm text via the speaker.

[0086] Specifically, alarm text is stored in advance in the processor, such as "The current volume is too loud, and the volume will be adjusted automatically." When the comparison result is that the target playback power exceeds the maximum playback power, the processor will broadcast the preset alarm text through the speaker to achieve the effect of warning the user.

[0087] In a feasible embodiment, the volume adjustment system is provided on a head-mounted device.

[0088] Specifically, the volume adjustment system is provided on a head-mounted device, including but not limited to smart glasses, a helmet, ear-hook headphones, etc.

[0089] In one feasible embodiment, the head-mounted device includes smart glasses, and the processor, the sensor and the speaker are arranged on the temples of the smart glasses.

[0090] For details, see Figure 4 As shown, Figure 4 A schematic diagram of a pair of smart glasses provided in accordance with a first embodiment of the present invention is shown, wherein a processor, a speaker, and a sensor are sequentially arranged on the temples of the smart glasses, and the sensor can contact the user's ear to generate a contact point.

[0091] In a feasible embodiment, a display screen is provided on the lens of the smart glasses, and text and images can be displayed in the window of the display screen.

[0092] Specifically, a display screen is provided on the lens of the smart glasses, and text and images can be displayed in the window of the display screen. The processor can display the target content to the user on the display screen.

[0093] When the comparison result shows that the target playback power exceeds the maximum playback power, the method further includes:

[0094] The processor displays the preset alarm text and alarm image in the window of the smart glasses.

[0095] Specifically, when the comparison result is that the target playback power exceeds the maximum playback power, the processor displays the preset alarm text (such as "volume too loud") in a window on the display screen, and displays the preset alarm image (such as a red exclamation mark) in a window on the display screen, so that the user can know from the display screen of the smart glasses through the glasses that the target playback power exceeds the maximum playback power, so as to warn the user.

[0096] Example 2

[0097] See the figure, Figure 5 FIG. 1 shows a structural diagram of a volume adjustment system provided by a second embodiment of the present invention, wherein Figure 5 As shown, a volume adjustment system provided by the second embodiment of the present invention includes a processor 501, a speaker 502 and a sensor 503. The processor 501 is electrically connected to the speaker 502 and the sensor 503 respectively. The sensor 503 is arranged at a position capable of contacting the user's ear and is in the shape of a bar:

[0098] The sensor is configured to send contact position information of a contact point between the user's ear and the sensor on the sensor to the processor;

[0103] The processor is used to adjust the current playback power of the speaker according to the comparison result, so that the speaker can perform sound broadcasting at the adjusted playback power.

[0104] In a feasible implementation manner, when the processor is used to adjust the playback power of the speaker according to the comparison result, it is specifically used to:
