[0066] Figure 1 FIG. 1 is a circuit diagram of a headset according to an embodiment of the present application. Figure 1 The headset 100 includes a controller 110, a sensor 120, a speaker module 130 and a database 140. The controller 110 is electrically connected to the sensor 120, the speaker module 130 and the database 140. In this embodiment, the controller 110 may be, for example, a control circuit such as a microcontroller unit (MCU), a digital signal processor (DSP) or a system in a chip (SoC). The sensor 120 may be a stress sensor or a force-sensitive resistor (FSR). The speaker module 130 includes a first speaker 131 and a second speaker 132, and the first speaker 131 and the second speaker 132 are electrically connected to the controller 110. The database 140 may be implemented by a memory or a related storage element, or may also be implemented by a memory element set in the controller 110. In this embodiment, the database 140 may store the target frequency response voltage value, the target frequency response parameter, the preset frequency response voltage value and the preset frequency response parameter described in each embodiment of the present application.
[0067] Figure 2 FIG. 1 is a schematic diagram showing the structure of a headset according to an embodiment of the present application. Figure 1 as well as Figure 2In this embodiment, the headset 100 further includes a headband support 150, a first stretching mechanism 161, a second stretching mechanism 162, a first earmuff 171 and a second earmuff 172. The first earmuff 171 is disposed at one end of the headband support 150 via the first stretching mechanism 161. The second earmuff 172 is disposed at the other end of the headband support 150 via the second stretching mechanism 162. In this embodiment, the sensor 120 may be disposed in the headband region 151 of the headband support 150, and is used to sense the stress change of the headband support 150, and output a corresponding voltage value to the controller 110 based on the corresponding circuit matched therewith, wherein the corresponding voltage value may be used as the frequency response voltage value referred to in each embodiment of the present application. The first speaker 131 may be disposed in the first earmuff 171. The second speaker 132 may be disposed in the second earmuff 172. The controller 110 may drive the first speaker 131 and the second speaker 132 to play audio according to the frequency response parameter. In addition, the controller 110 and the database 140 may be disposed in the headband bracket 150 , or in the first earmuff 171 or the second earmuff 172 , and the present application is not limited thereto.
[0068] Figure 3 FIG. 1 is a flowchart showing a method for operating a headset according to an embodiment of the present application. Figures 1 to 3 In this embodiment, when the user wears the headset 100, the headset 100 may perform the following operations S310 to S340. In step S310, the sensor 120 may sense the stress change of the headband bracket 150 to output a frequency response voltage value. The stress change of the headband bracket 150 refers to the stress change caused by the deformation of the body of the headband bracket 150 due to the user wearing the headset.
[0069] In this regard, if the width of the user's head (e.g., cheek width or distance between ears) is wider, the distance between the first earmuff 171 and the second earmuff 172 is larger, and the stress on the headband bracket 150 is also higher. On the contrary, if the width of the user's head is narrower, the distance between the first earmuff 171 and the second earmuff 172 is smaller, and the stress on the headband bracket 150 is also lower. In addition, if the head width is a fixed condition, if the user's head length (e.g., the distance from the top of the head to the center of the ears) is longer, the user can lengthen the first stretching mechanism 161 and the second stretching mechanism 162, and the stress on the headband bracket 150 may be reduced. On the contrary, if the head width is a fixed condition, if the user's head length is shorter, the user can shorten the first stretching mechanism 161 and the second stretching mechanism 162, and the stress on the headband bracket 150 may be increased.
[0070] In other words, when different users have different head widths and / or head lengths, the stress changes of the headband bracket 150 caused by different users wearing the headset 100 are also different. More importantly, since the deformation degree of the headband bracket 150 is related to the fit degree of the first earmuff 171 and the second earmuff 172 to the user's ears, from another perspective, the stress change of the headband bracket 150 changes with the fit degree of the first earmuff 171 and the second earmuff 172 to the user's ears. Therefore, the headset 100 of this embodiment can use the stress change of the headband bracket 150 as a basis for adjusting the frequency response parameters of the audio playback mode of the first speaker 131 and the second speaker 132.
[0071] In step S320, the controller 110 may receive a frequency response voltage value corresponding to the current stress level of the headband bracket 150 from the sensor 120. In step S330, the controller 110 may determine whether the frequency response voltage value is the same as the target frequency response voltage value to read a target frequency response parameter corresponding to the target frequency response voltage value. If the frequency response voltage value is the same as the target frequency response voltage value, in step S340, the controller 110 may drive the first speaker 131 and the second speaker 132 of the speaker module 130 according to the target frequency response parameter.
[0072] Specifically, the target frequency response parameter may be an ideal frequency response parameter, which means that the first speaker 131 and the second speaker 132 can be operated in a specific audio playback mode so that the preset user object can hear the ideal audio quality. The controller 110 can compare whether the current frequency response voltage value is the same as the target frequency response voltage value. If they are the same, the controller 110 can directly use the target frequency response parameter corresponding to the target frequency response voltage value to drive the first speaker 131 and the second speaker 132. If they are not the same, the controller 110 can read the database 140 to select the preset frequency response parameter corresponding to the preset frequency response voltage value closest to or the same as the frequency response voltage value to drive the first speaker 131 and the second speaker 132 of the speaker module, so as to adjust the audio playback mode of the first speaker 131 and the second speaker 132 accordingly, so that the audio quality heard by the user through the first speaker 131 and the second speaker 132 can be close to or equal to the ideal audio quality.
[0073] 4A to 4D Schematic diagrams showing various usage scenarios of the headsets of various embodiments of the present application. Figure 4AAssuming that the head width of the user wearing the headset 100 is narrow (the head width is, for example, 132 millimeters (mm)) and the head length is short, then when the first stretching mechanism 161 and the second stretching mechanism 162 are in an unstretched state, the center point P1 of the headband to the center point P2 of the earmuff has a first height HC1 (for example, 122 millimeters), and there is a distance L1 between the first earmuff 171 and the second earmuff 172.
[0074] refer to Figure 4B Assuming that the head width of the user wearing the headset 100 is wider (for example, the head width is 169 mm) and the head length is shorter, when the first stretching mechanism 161 and the second stretching mechanism 162 are in an unstretched state, the center point P1 of the headband to the center point P2 of the earmuff has a first height HC1 (for example, 122 mm), and there is a distance L2 between the first earmuff 171 and the second earmuff 172.
[0075] refer to Figure 4C Assuming that the head width of the user wearing the headset 100 is narrow (the head width is, for example, 132 mm) and the head length is long, when the first stretching mechanism 161 and the second stretching mechanism 162 are in a stretched state, the center point P1 of the headband to the center point P2 of the earmuff has a second height HC2 (for example, 146 mm), and there is a distance L3 between the first earmuff 171 and the second earmuff 172.
[0076] refer to Figure 4D Assuming that the head width of the user wearing the headset 100 is wider (for example, the head width is 169 mm) and the head length is longer, when the first stretching mechanism 161 and the second stretching mechanism 162 are in a stretched state, the center point P1 of the headband to the center point P2 of the earmuff has a second height HC2 (for example, 146 mm), and there is a distance L4 between the first earmuff 171 and the second earmuff 172.
[0077] In this regard, 4A to 4D As shown in FIG. 1 , in the above four scenarios, distance L2 may have the maximum distance, and distance L3 may have the minimum distance. Distance L2 is greater than distance L4. Distance L4 is greater than distance L1. Distance L1 is greater than distance L3. Therefore, it can be known that the headband bracket 150 is Figure 4B The maximum stress value may be obtained in the use scenario of (i.e., the clamping force generated by the headband support 150, the first earmuff 171 and the second earmuff 172 is relatively large). Figure 4D The headband bracket 150 may have the second largest stress value in the use scenario (that is, the clamping force generated by the headband bracket 150, the first earmuff 171 and the second earmuff 172 is second). Figure 4AThe headband bracket 150 may have the third largest stress value in the use scenario (i.e., the clamping force generated by the headband bracket 150, the first earmuff 171 and the second earmuff 172 is the largest and the second largest). Figure 4C In the usage scenario, the stress value may be the smallest (i.e., the clamping force generated by the headband bracket 150, the first earmuff 171, and the second earmuff 172 is small). In this way, the controller 110 can determine whether to drive the first speaker 131 and the second speaker 132 according to the target frequency response parameter or the preset frequency response parameter according to the frequency response voltage value output by the sensor 120.
[0078] Furthermore, refer to Figure 5 , Figure 5 FIG. 2 is a schematic diagram of a frequency response curve of an embodiment of the present application. For example, the target frequency response parameter can allow the audio played by the first speaker 131 and the second speaker 132 to have the following characteristics: Figure 5 However, in the case where the clamping force generated by the headband support 150, the first earmuff 171 and the second earmuff 172 is large, the frequency response parameters may correspond to Figure 5 The frequency response curve 502 shown. In this regard, since the sound leakage from the front cavities of the first earmuffs 171 and the second earmuffs 172 is small, the user may feel a stronger low frequency when listening to audio. Therefore, the controller 110 can change the currently used frequency response parameters (adjusted by preset frequency response parameters) to appropriately reduce the frequency response curve of the low frequency, so that the frequency response curve of the audio heard by the user can be close to the ideal frequency response curve 501.
[0079] In contrast, when the clamping force generated by the headband support 150, the first earmuff 171 and the second earmuff 172 is small, the frequency response parameter may correspond to Figure 5 The frequency response curve 503 is shown. In this regard, since the sound leakage from the front cavities of the first earmuff 171 and the second earmuff 172 is relatively large, the user's low-frequency feeling when listening to audio is relatively weak. Therefore, the controller 110 can change the currently used frequency response parameter (adjusted by another preset frequency response parameter) to appropriately improve the frequency response curve of the low frequency, so that the frequency response curve of the audio heard by the user can be close to the ideal frequency response curve 501.
[0080] In addition, regarding the position design of the headband area 151 on the headband bracket 150, please refer to 4A to 4D .exist Figure 4A and Figure 4BWhen the first stretching mechanism 161 and the second stretching mechanism 162 are in an unstretched state, the deformation of the headband bracket 150 is concentrated on both sides of the headband center point P1. Therefore, the headband area 151 where the sensor 120 is set can preferably correspond to the ratio area of the first reference height R1 of the headband bracket 150 from the headband center point P1 to the earmuff center point P2 of the first earmuff 171 and the second earmuff 172. The first reference height R1 is equal to the result of multiplying the first height HC1 by a preset ratio. And, Figure 4C and Figure 4D When the first stretching mechanism 161 and the second stretching mechanism 162 are in the stretching state, the deformation of the headband bracket 150 is also concentrated on both sides of the headband center point P1, so the headband area 151 where the sensor 120 is set can preferably correspond to the ratio area of the second reference height R2 of the headband bracket 150 from the headband center point P1 to the earmuff center point P2 of the first earmuff 171 and the second earmuff 172. The second reference height R2 is equal to the result of multiplying the second height HC2 by the preset ratio.
[0081] Therefore, based on the difference between the first stretching mechanism 161 and the second stretching mechanism 162 in the unstretched state and the stretched state, the headband area 151 where the sensor 120 of the present embodiment is set may be within a preset ratio area corresponding to the preset height from the headband center point P1 to the earmuff center point P2 of the headband bracket 150. The preset height may be between (or may be selected from) the first reference height R1 and the second reference height R2. In one embodiment, the first height HC1 may be 122 mm, the second height HC2 may be 146 mm, and the preset ratio is 20%, but the present application is not limited thereto.
[0082] Figure 6 FIG. 1 is a flowchart showing a method for operating a headset according to another embodiment of the present application. Figure 1 , Figure 2 as well as Figure 6In step S610, the sensor 120 may sense the stress change of the headband bracket 150 to obtain the frequency response voltage value. The sensor 120 may output the frequency response voltage value to the controller 110. In step S620, the sensor 120 determines whether the frequency response voltage value is greater than or equal to the voltage threshold value to determine whether to further determine whether the frequency response voltage value is the same as the target frequency response voltage value. Specifically, the controller 110 may confirm whether the user is wearing the headset 100 by determining whether the frequency response voltage value is greater than or equal to the voltage threshold value. It should be noted that the voltage threshold value may be, for example, a minimum voltage value (i.e., a trigger voltage value) generated by the sensor 120 when the headset 100 is worn, which is pre-set during the product manufacturing process. If not, the controller 110 may re-execute step S610. If yes, in step S630, the controller 110 may further determine whether the frequency response voltage value is the same as the target frequency response voltage value.
[0083] If yes, in step S640, the controller 110 may use the target frequency response parameter corresponding to the target frequency response voltage value to drive the first speaker 131 and the second speaker 132 of the speaker module 130. If no, in step S650, the controller 110 may select a preset frequency response parameter corresponding to a preset frequency response voltage value closest to or the same as the frequency response voltage value from the database 140 to drive the speaker module 130 to complete the adaptability adjustment. Therefore, the headset 100 and the operating method thereof of this embodiment can effectively and automatically adjust the audio quality provided by the first speaker 131 and the second speaker 132 of the speaker module 130.
[0084] It should be noted that the database 140 may be established, for example, during the product design and manufacturing process. The database 140 may record a plurality of preset frequency response voltage values and a plurality of preset frequency response parameters corresponding thereto. In this regard, in a plurality of cases where the headband bracket 150 applies different clamping forces, the voltage values output by the sensor 120 may be collected as a plurality of preset frequency response voltage values, and a plurality of frequency response parameters of the best audio quality played by the first speaker 131 and the second speaker 132 of the speaker module 130 may be collected as a plurality of preset frequency response parameters.
[0085] In addition, the above-mentioned target frequency response voltage value may be, for example, a voltage value output by the sensor 120 when the headband bracket 150 clamps the B&K TYPE 4128C head and torso simulator (HATS), and the target frequency response parameter may be, for example, a frequency response curve of the best audio quality (or specific audio quality) played by the first speaker 131 and the second speaker 132 when the headband bracket 150 clamps the B&K TYPE 4128C head and torso simulator (HATS), but the present application is not limited to this.
[0086] In summary, the headset and its operating method of the present application can automatically adjust the frequency response parameters used to drive the speaker module accordingly by sensing the stress changes of the head mount, so that different users with different head sizes can receive similar or better audio playback quality.
[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
