Description

Technical Field

[0001] The present application relates to the technical field of equipment detection, and in particular to a pressing abnormal sound testing device. Background Art

[0002] With the growing trend toward more diverse electronic devices, such as candy-bar phones, foldable phones, and tablets, some are pursuing ultra-thin and ultra-light features. Consequently, electronic devices (both prototypes and finished products) face numerous structural and dimensional challenges. For speakers in electronic devices, the space they can occupy inside the device is often insufficient (corresponding to the device's reduced thickness). This results in insufficient rear volume and a narrow front cavity. Consequently, some electronic devices employ open-cavity speaker designs, such as an open front cavity, an open rear cavity, or dual-open cavities.

[0003] Furthermore, the requirements for electronic devices to be waterproof are becoming increasingly stringent, and the corresponding degree of sealing is becoming increasingly strict. When a terminal device is subjected to a sudden force, the airflow inside and outside the device becomes unbalanced. This impact airflow can easily impact the most flexible part of the diaphragm of the speaker's open cavity, sometimes causing polarization of the coil fixed to the diaphragm and generating noise.

[0004] As some electronic devices become thinner and lighter, they are increasingly susceptible to the problem of abnormal pressing noises caused by users' sudden pressing actions. Therefore, it is necessary to more accurately evaluate the ability of electronic devices to resist abnormal pressing noises so as to reduce the possibility of abnormal pressing noises when electronic devices are used.

[0029] Specifically, refer to Figure 1 , the device housing 110 may provide a structural framework for the electronic device 100; for example, Figure 1 and Figure 2In the device housing 110, the device housing 110 may include a middle frame 111 and a back cover 112.

For example, the middle frame 111 may include a middle plate 113 and a frame 114, with the frame 114 disposed along the perimeter of the middle plate 113. Generally, the frame 114 may include a top frame, a bottom frame, a left frame and a right frame, and the top frame, the bottom frame, the left frame and the right frame form a frame with a square ring structure; the circuit board 120, the battery 130, the camera module 140, the USB device and the speaker 150 are arranged on the side of the middle plate 113 facing the back cover 112, or the circuit board 120, the battery 130, the camera module 140, the speaker and the USB device 150 can be arranged on the side of the middle plate 113 facing the screen 160.

[0031] Continue to refer Figure 2 As shown, in the electronic device 100 corresponding to the embodiment of the press-to-sound test device provided in the present application, the circuit board 120 may include a main circuit board 121 and a sub-circuit board 122. The main circuit board 121 is used to integrate a control chip, and the control chip may be, for example, an application processor (AP). In some embodiments, the main circuit board 121 is electrically connected to the display screen 162, and the main circuit board 121 is used to control the display screen 162 to display images or videos. The sub-circuit board 122 is used to integrate electronic components such as antennas (such as 5G antennas) and radio frequency front ends. The sub-circuit board 122 is electrically connected to the main circuit board 121 through a conductor 170 to realize data and signal transmission between the sub-circuit board 122 and the main circuit board 121. The conductor 170 may be a flexible printed circuit (FPC), a wire, or an enameled wire.

[0032] A USB device can be connected to the secondary circuit board 122. The USB device is an interface device that complies with USB standards. Specifically, the USB device can be a USB Type-C device, etc. The USB device can be connected to a charger via the socket 115 on the frame 114 to charge the electronic device 100. It can also be used to transfer data between the electronic device 100 and peripheral devices, and can also be used to connect headphones to play audio through the headphones. Furthermore, the USB device can be used to connect to other electronic devices.

[0033] The speaker 150 is used to convert audio signals such as music and voice into sound, and can support the audio external speaker function. In some embodiments, the speaker 150 is electrically connected to the auxiliary circuit board 122. At this time, the audio signal sent by the main circuit board 121 is transmitted to the speaker 150 through the auxiliary circuit board 122, and is converted into a sound signal output by the speaker 150. Specifically, refer to Figure 1 and Figure 2 , a sound outlet channel 151 is provided on the outer shell of the speaker 150. The sound signal output by the speaker 150 is output by the sound outlet channel 151, and a sound outlet hole 116 is provided on the frame 114, and the sound outlet hole 116 is connected to the sound outlet channel 151; the sound output by the sound outlet channel 151 is output to the outside of the electronic device 100 through the sound outlet hole 116. Among them, the speaker 150 is arranged in the device housing 110. Alternatively, part of the device housing 110 forms at least part of the sound outlet housing, which can be understood as part or all of the sound outlet housing of the speaker 150 as part of the device housing. In other embodiments, the speaker 150 can also be directly electrically connected to the main circuit board 121 through FPC, wire, enameled wire, etc.

[0034] Figure 3 The schematic diagram of the speaker 150 in the electronic device 100 corresponding to an embodiment of the pressing abnormal sound test device provided by the present application is shown. Figure 3 The speaker 150 includes a basin frame 152, a diaphragm 153, a coil 154, a magnet assembly 155, etc., wherein the magnet assembly 155 can be configured to include a magnet and a yoke, etc. The diaphragm 153 is connected to the side wall of the basin frame 152, for example, it can be fixedly connected by means of gluing, snapping, etc., and this embodiment is not limited to this. Among them, the coil 154 and the magnet assembly 155 are respectively accommodated in the basin frame 152. The coil 154 can be arranged between the diaphragm 153 and the magnet assembly 155, for example, the diaphragm 153, the coil 154 and the magnet assembly 155 are arranged in sequence from top to bottom. One end of the coil 154 is connected to the diaphragm 153, for example, it can be fixedly connected by means of gluing, etc., and the other end of the coil 154 extends toward the magnet assembly 155.

[0035] With the development trend of diversified forms of electronic devices 100 such as straight-screen mobile phones, folding mobile phones and tablet computers, some electronic devices 100 are developing in the direction of pursuing ultra-thin and ultra-light characteristics. Therefore, the electronic device 100 (including prototypes and finished products) faces various challenges in structure and size. For the speaker 150 of the electronic device 100, the space that the speaker 150 can occupy inside the electronic device 100 faces the problem of insufficient height (corresponding to the thinning of the electronic device 100), which leads to insufficient volume of the back cavity of the sound cavity of the speaker 150 and narrow space of the front cavity of the sound cavity of the speaker 150. Therefore, referring to Figure 3 , some electronic devices 100 set the sound cavity of the speaker 150 to be an open cavity, for example, an open front cavity, an open rear cavity or a double open cavity, etc. Figure 3 The lower end of the center speaker 150 is open.

[0036] Furthermore, the requirements for electronic devices 100 to be waterproof are becoming increasingly stringent, and the corresponding degree of sealing is becoming increasingly stringent. When a force is applied to the terminal device 100 instantaneously, the airflow inside and outside the electronic device 100 becomes unbalanced. This impact airflow can easily impact the softest part of the diaphragm 153 of the speaker 150 in the open cavity, sometimes causing polarization of the coil 154 fixed to the diaphragm 153 and generating noise.

[0037] As some electronic devices 100 become thinner and lighter, it is more and more likely that the electronic device 100 will cause abnormal pressing noise due to the user's instantaneous pressing action. Figure 1 and Figure 2 When users are playing games or other interactive operations, they may press the screen 160 and the corresponding back cover 112 hard due to nervousness or excitement, which may cause the electronic device 100 to produce abnormal pressing sounds.

[0038] Therefore, it is necessary to more accurately evaluate the ability of the electronic device 100 to resist abnormal pressing noise, so as to reduce the possibility of the electronic device 100 generating abnormal pressing noise when being used by the user.

[0039] Reference Figure 4 The present application provides a pressure-induced noise testing device 200 to improve the accuracy of evaluating the ability of an electronic device 100 to resist pressure-induced noise.

[0040] in, Figure 4 The following is a structural diagram of an embodiment of a pressing abnormal sound testing device 200 provided in this application. Figure 5 The circuit connection diagram of an embodiment of the abnormal sound test device 200 provided by the present application is shown. Figure 4 and Figure 5The pressing abnormal sound testing device 200 includes a force applying device 210, a pressure sensor 220 and a first detection device 230. The force applying device 210 includes a movable force applying body 211, which is configured to apply a force to the preset surface 101 of the electronic device 100; wherein, referring to Figure 2 , the preset surface 101 can be set as the surface on the screen 160 or the back cover 112 of the electronic device 100. In some embodiments, the force-applying device 210 includes a mechanical arm, and the force-applying body 211 includes a mechanical finger on the free end of the mechanical arm, thereby improving the stability of the applied force. Of course, the force-applying device 210 can also be set to include a drive motor, a drive cylinder, and a connecting rod mechanism, a cam mechanism, etc. that are transmission-connected to the drive motor and the drive cylinder; or, the force-applying device 210 can also be set to apply a force to the preset surface 101 of the electronic device 100 through negative pressure, for example, the force-applying body 211 can be set as a suction cup, etc.

[0041] The pressure sensor 220 has a sensing position relative to the predetermined surface 101. It can be understood that the pressure sensor 220 is fixed at the sensing position or can be moved to the sensing position, although this embodiment is not limited thereto. At the sensing position, the pressure sensor 220 is connected to the force-applying body 211 or the predetermined surface 101. The pressure sensor 220 is configured to sense force information between the force-applying body 211 and the predetermined surface 101. The force information can include at least one of force velocity, force magnitude, contact area, and duration of force application. The first detection device 230 is positioned relative to the electronic device 100 and is further configured to detect sound waves or airflow output by the electronic device 100. For example, the first detection device 230 includes at least one of a sound pickup device and an airflow meter, thereby capturing audio emitted by the electronic device 100 through the sound pickup device or detecting airflow from the electronic device 100 through the airflow meter. The sound pickup device can include a standard microphone (also known as a reference microphone). An airflow meter can be understood as a device that responds to the flow and direction of air or gas and provides a corresponding output voltage.

[0042] Among them, if the first detection device 230 is also configured to detect the sound waves output by the electronic device 100, when the press-to-press abnormal sound test device 200 in this embodiment is used, the electronic device 100 to be tested can first be allowed to play audio of a preset duration and preset amplitude without being applied force by the force-applying body 211 through the preset surface 101, wherein the audio can be pink noise, a sweep frequency signal, or other music; wherein pink noise can be understood as noise between white noise and red noise. When the electronic device 100 to be tested plays audio, the sound waves output by the electronic device 100 can be detected by the first detection device 230.

[0043] Afterwards, the electronic device plays the same audio again and uses the force-applying body 211 to apply force through the preset surface 101 ; when the electronic device 100 to be tested plays audio, the sound waves output by the electronic device 100 can be detected by the first detection device 230 .

[0044] Thus, the first detection device 230 detects the same audio played by the electronic device 100 under test, both when no force is applied by the force-applying body 211 through the preset surface 101 and when the force is applied by the force-applying body 211 through the preset surface 101. These two detection sound waves can be evaluated by professional audio testers or by using existing audio analysis software to assess the impact of the problem through factors such as time domain RMS amplitude, acoustic signal energy, and distortion.

[0045] Of course, the first detection device 230 can also be used to directly detect whether there is noise caused by abnormal airflow when a force is applied to the electronic device 100. The noise amplitude in dB or the frequency domain value can be extracted through existing frequency domain comparison or time domain comparison as a criterion for determining the noise level, thereby identifying whether there is noise.

[0046] In addition, if the first detection device 230 is also configured to detect the airflow output by the electronic device 100, the airflow signal can be picked up by the first detection device 230, and then compared with the airflow value when the source sound is playing normally (when the electronic device 100 is not subjected to force by the force-applying body 211), so as to characterize whether the electronic device 100 will produce abnormal pressing sound by judging the airflow signal.

[0047] According to the above analysis, by adopting the above embodiment, the pressing abnormal sound testing device 200 can more accurately obtain the force information between the force-applying body 211 and the preset surface 101 through the pressure sensor 220 when the force-applying body 211 applies a force to the preset surface 101 of the electronic device 100, and can detect the sound waves or airflow output by the electronic device 100 through the first detection device 230 to obtain the abnormal sound level of the electronic device 100, thereby being able to more accurately evaluate the abnormal sound level of the electronic device 100 under the same force, thereby improving the accuracy of evaluating the ability of the electronic device 100 to resist pressing abnormal sound.

[0048] In some embodiments, the pressure sensor 220 is connected to the force-applying end 212 of the force-applying body 211, and the pressure sensor 220 is configured to be driven by the force-applying body 211 to move to the sensing position. Specifically, the pressure sensor 220 can be integrated into the force-applying body 211, for example, integrated into the mechanical finger on the free end of the robotic arm, thereby reducing the risk of damage to the pressure sensor 220 due to collision. Of course, the pressure sensor 220 can also be provided separately from the force-applying body 211, with the pressure sensor 220 connected to the surface of the force-applying end 212 of the force-applying body 211, thereby reducing the difficulty of manufacturing the corresponding force-applying device 210 and the overall cost, such as reducing the difficulty of integrating the corresponding robotic arm integrated pressure sensor 220 and the corresponding cost of the integration process. Furthermore, the surface of the pressure sensor 220 can be provided with an adhesive layer, for example, the adhesive layer is provided as a double-sided tape, glue layer, etc., and the adhesive layer is bonded to the surface of the force-applying end 212 of the force-applying body 211, thereby further reducing the difficulty of manufacturing the corresponding force-applying device 210 and the overall cost.

[0049] In some embodiments, the force-applying end 212 of the force-applying body 211 is configured to move along at least one of a first direction and a second direction, the first direction and the second direction being parallel to the preset surface 101, respectively. The first direction and the second direction have an angle therebetween, and the angle can be set to be greater than 0 degrees and less than or equal to 90 degrees, for example, 30 degrees, 45 degrees, 60 degrees, 90 degrees, etc. The first direction can be set to the Y-axis direction in the figure, and the second direction can be set to the X-axis direction in the figure. In addition, a guide rail can be provided for the force-applying device 210 so that the force-applying body 211 can move along the guide rail with the force-applying device 210; of course, the force-applying device can also be provided as a robotic arm with a degree of freedom of movement, so that the force-applying end 212 of the force-applying body 211 can move along at least one of the first direction Y and the second direction X.

[0050] In this embodiment, the force-applying end 212 of the force-applying body 211 is configured to move along at least one of the first direction and the second direction, which is conducive to the force-applying end 212 of the force-applying body 211 applying force to multiple positions on the preset surface 101, thereby enabling a more comprehensive evaluation of the ability of the electronic device 100 to resist abnormal pressing noise.

[0051] In some embodiments, the length of the preset surface 101 in the first direction Y is greater than the length of the preset surface 101 in the second direction X. For example, the first direction Y is set to the length direction of the screen 160 of the electronic device 100, and the second direction X is set to the width direction of the screen 160 of the electronic device 100. Because the length of the preset surface 101 in the first direction Y is greater than the length of the preset surface 101 in the second direction X, the bending resistance of the preset surface 101 in the first direction Y is relatively poor, and the preset surface 101 is more likely to have multiple locations in the first direction Y that generate abnormal pressing noise. In contrast, the force-applying end 212 of the force-applying body 211 is configured to move at least along the first direction Y, thereby more efficiently evaluating the ability of the electronic device 100 to resist abnormal pressing noise in the first direction Y.

[0052] In some embodiments, reference Figure 4 The force-applying body 211 includes two mechanical fingers disposed opposite to each other on the free end of the mechanical arm; one of the two mechanical fingers disposed opposite to each other is configured to abut against the preset surface 101, and the other of the two mechanical fingers disposed opposite to each other is configured to abut against the side of the electronic device 100 facing away from the preset surface 101, for example Figure 4 The two oppositely disposed mechanical parts respectively abut against the upper and lower sides of the electronic device 100 .

[0053] In this embodiment, the pressure-induced noise testing device 200 can more accurately simulate the user's usage posture of the electronic device 100 through two oppositely arranged mechanical fingers, which is conducive to improving the accuracy of evaluating the ability of the electronic device 100 to resist pressure-induced noise.

[0054] In some embodiments, reference Figure 4 The pressing noise testing device 200 includes two force applying devices 210 spaced apart. The force applying body 211 on at least one force applying device 210 is configured to move along the arrangement direction of the two force applying devices 210, for example, along Figure 4 The left and right movements in the image are simulated more accurately to simulate the relative movement between the two hands of the user when using the electronic device 100, thereby facilitating further improving the accuracy of evaluating the ability of the electronic device 100 to resist abnormal pressing sounds.

[0055] Furthermore, the two spaced-apart force-applying devices 210 are configured to correspond to the two ends of the electronic device 100 in the first direction Y, respectively, and the force-applying body 211 on at least one force-applying device 210 is configured to move along the arrangement direction of the two force-applying devices 210, thereby more accurately simulating the more frequent relative movement between the two hands of the user in the longer first direction Y when the user is using the electronic device 100, which is conducive to further improving the accuracy of evaluating the ability of the electronic device 100 to resist abnormal pressing noise.

[0056] In some embodiments, the first detection device 230 is configured to move along at least one of a third direction and a fourth direction, the third direction and the fourth direction are respectively parallel to the preset surface 101, and there is an angle between the third direction and the fourth direction, which can be set to be greater than 0 degrees and less than or equal to 90 degrees, for example, 30 degrees, 45 degrees, 60 degrees, 90 degrees, etc. The third direction can be set to the Y-axis direction in the figure, and the fourth direction can be set to the X-axis direction in the figure. In addition, a guide rail can be provided to the force-applying device 210, so that the first detection device 230 moves on the guide rail; of course, the first detection device 230 can also be clamped by a robotic arm with a degree of freedom of movement, so that the first detection device 230 can move along at least one of the third direction Y and the fourth direction X.

[0057] In this embodiment, the first detection device 230 is configured to move along at least one of the third direction and the fourth direction, so as to move to a position where the sound waves or airflow output by the electronic device 100 can be more accurately detected, which is beneficial to improving the detection accuracy of the first detection device 230.

[0058] In some embodiments, reference Figure 5 The pressure-induced noise testing device 200 also includes a signal processing device 240, which includes a preset sound wave processing circuit 241. The signal input of the preset sound wave processing circuit 241 is electrically connected to the first detection device 230 for detecting sound waves. This allows for more rapid evaluation of the electronic device 100's ability to resist pressure-induced noise by processing the sound waves. The preset sound wave processing circuit 241 may include a filter, an amplifier, and a digital signal processor (DSP), thereby performing operations such as filtering, amplification, and spectrum analysis on the sound wave signal.
