For example, one way of mounting the vibration exciting member 21 may be that, as shown in fig. 2 and 4, the side of the vibration exciting member 21 adjacent to the first surface 111 of the side wall 11 may be fixed to the groove wall by gluing, and the side adjacent to the second surface 112 of the side wall 11 may be attached to the groove wall.
In practice, the side of the vibration exciting member 21 adjacent to the first surface 111 of the side wall 11 may be fixed to the inner groove wall of the mounting groove 12 by gluing or the like, and the side adjacent to the second surface 112 of the side wall 11 may be in contact with the outer groove wall. Wherein the fixing by means of gluing is for fixing the vibration exciting member 21, and the contact is for providing a deformation space for the vibration of the vibration exciting member 21. The vibration exciting member 21 may be in surface contact with the outer groove wall, or in line contact with the outer groove wall, or in point contact with the outer groove wall, where the specific situation is related to the shape of the vibration exciting member 21 and the specific placement of the vibration exciting member 21, and this embodiment is not limited to this, and those skilled in the art may flexibly set the vibration exciting member according to actual needs.
Therefore, in the process of vibrating the vibration excitation component 21, the vibration can be directly transmitted to the groove wall in contact with the vibration excitation component and finally fed back to a user, and the installation mode can reduce the vibration transmission path and accelerate the vibration feedback speed.
Optionally, in order to avoid the vibration exciting member 21 from being damaged during the vibration process, the vibration exciting member 21 may be indirectly mounted in the mounting groove 12 through other members, for example, as shown in fig. 5, the vibration module 2 may further include a vibration transmitting member 24, the vibration transmitting member 24 is fixed on the groove wall of the mounting groove 12, and the vibration exciting member 21 is fixed on the vibration transmitting member 24.
In order to make the vibration transmission member 24 vibrate along with the vibration exciting member 21, the vibration transmission member 24 may be a relatively small damping member, for example, an alloy sheet such as a steel sheet, and a relatively thin steel sheet may vibrate along with the vibration exciting member 21, and further, may transmit the vibration to the groove wall of the mounting groove 12.
In practice, the vibration transfer member 24 may be mounted on a wall of the mounting groove 12, in a manner to be described below. The vibration exciting member 21 is fixed to the vibration transmitting member 24, for example, the vibration exciting member 21 may be fixed to the vibration transmitting member 24 by means of gluing or the like, and when the vibration exciting member 21 vibrates, it may vibrate together with the vibration transmitting member 24, and then the vibration transmitting member 24 transmits the vibration to the groove wall of the mounting groove 12.
It should be noted that, the embodiment is not limited to this, and for example, the vibration exciting member 21 may be fixed above the vibration transmitting member 24, and for example, the vibration exciting member 21 may also be fixed below the vibration transmitting member 24, and a person skilled in the art may flexibly determine the position of the vibration exciting member 21 on the vibration transmitting member 24 according to actual requirements.
Alternatively, the vibration transfer member 24 may be cantilever-mounted on a groove wall of the mounting groove 12, and accordingly, as shown in fig. 5, the mounting groove 12 may include a first mounting groove 121 and a second mounting groove 122 which are communicated with each other; a first portion of the vibration transfer member 24 is fixed to a groove wall of the first mounting groove 121, a second portion of the vibration transfer member 24 is suspended in the second mounting groove 122, and the vibration exciting member 21 is fixed to the second portion of the vibration transfer member 24.
In an embodiment, the vibration transmission member 24 has a certain length, and the vibration transmission member 24 may be divided into two parts, i.e., a first part and a second part, respectively, and the mounting groove 12 may be divided into two parts, i.e., a first mounting groove 121 and a second mounting groove 122, respectively. In this way, the first portion of the vibration transfer member 24 may be fixed to the wall of the first mounting groove 121, and the remaining portion, i.e., the second portion, of the vibration transfer member 24 may be suspended in the second mounting groove 122, wherein the vibration exciting member 21 may be fixed to the second portion of the vibration transfer member 24, and thus, the vibration exciting member 21 may be suspended in the second mounting groove 122 along with the vibration transfer member 24. When the vibration exciting member 21 vibrates, the second portion of the vibration transmitting member 24 may vibrate together, the vibration generated by the second portion of the vibration transmitting member 24 may transmit the vibration to the first portion, and the first portion of the vibration transmitting member 24 may transmit the vibration to the groove wall of the mounting groove 12, so as to feed the vibration back to the user, and the specific flow may refer to the flowchart shown in fig. 6.
In one possible application, in order to save the installation space, accordingly, the first portion of the vibration transmission member 24, the touch detection member 23, and the wiring board 26 may be installed in the first installation groove 121. As shown in fig. 5, the first portion of the vibration transmission member 24 may be fixed to the inner groove wall of the first mounting groove 121 by gluing, and the reinforcing steel 262 of the circuit board 26 may be fixed to the first portion of the vibration transmission member 24, and the touch detection member 23 may be fixed to the circuit board 26. Wherein, touch the detection face of pressing detection part 23 and the installation of the outer wall of first mounting groove 121 mutually, press many times and touch under the condition of pressing detection part 23, in order to avoid touching detection part 23 and taking place to rock in first mounting groove 121, it is corresponding to touch and to press detection part 23 and can install between the inner wall of first mounting groove 121 and circuit board 26 by the interference to strengthen the fastness of touching detection part 23.
Optionally, the vibration type of the vibration assembly 2 may be set by a technician according to actual requirements, and the vibration type of the vibration assembly 2 is determined through theoretical calculation and multiple tests, wherein the vibration type of the vibration assembly 2 is mainly related to the intensity of the vibration assembly 2 and the frequency of the vibration change. There are various ways of adjusting the vibration type of the vibration assembly 2, and for example, an appropriate vibration type may be determined by adjusting the current to the vibration exciting member 21 or the voltage applied to the vibration exciting member 21. For example, the voltage may be controlled by controlling the value of the voltage, the waveform of the voltage change, the frequency of the voltage change, and the like to make the vibration exciting member 21 to achieve a suitable vibration type. For another example, by adjusting the size of the vibration exciting member 21. For example, the length of the second portion of the vibration transmission member 24 may be adjusted.
Alternatively, another way of adjusting the vibration type may also be that, as shown in fig. 7, the vibration assembly 2 further includes a mass 25, and the mass 25 is fixed to the second portion of the vibration transfer member 24.
The mass 25 is mainly used to adjust the vibration type of the vibration transmission member 24, and the fixing position of the mass 25 on the second portion of the vibration transmission member 24 is not limited in this embodiment.
In practice, the technician may determine the type of vibration of the vibration assembly 2 by adjusting the mass of the mass 25, the spacing between the mass 25 and the vibration exciting member 21, and the like. In the design stage, the technician can adjust the vibration condition of the vibration transmission member 24 through the mass 25 and the voltage applied to the vibration exciting member 21 based on the actual condition of the terminal.
In the installation manner of the vibration component 2 in the installation groove 12 as shown in fig. 7, the solid line arrow in the figure indicates the touching direction of the user, and the transmission route of the vibration can be transmitted to the second surface 112 of the side wall 11 along the side wall 11 of the middle frame 1 through the inner groove wall of the first installation groove 121 as shown by the dotted line arrow, wherein the user can feel the vibration feedback by contacting with the second surface 112 of the side wall 11.
In one possible embodiment, in the case where the vibration transmission member 24 is cantilever-mounted in the mounting groove 12, the vibration module 2 may be assembled by fixing the base plate 261 of the circuit board 26 to the reinforcing steel 262, and soldering the control member 22 and the contact detection member 23 to the base plate 261 by solder as an assembly; the technician then fixes the vibration exciting member 21 and the mass respectively to the first portion of the vibration transmitting member 24 as another assembly; thereafter, the technician can install the above two assemblies in the installation groove 12 in accordance with the positional relationship in the first installation groove 121 and the second installation groove 122.
Alternatively, the vibration transmission member 24 may be installed in the mounting groove 12 in a manner that both ends of the vibration transmission member are fixed to the groove wall of the mounting groove 12 and the middle of the vibration transmission member is not fixed to the groove wall of the mounting groove 12, and accordingly, as shown in fig. 8, the mounting groove 12 may include a first mounting groove 121, a second mounting groove 122 and a third mounting groove 123 which are communicated with each other, and the third mounting groove 123 is located between the first mounting groove 121 and the second mounting groove 122; the first portion of the vibration transmission member 24 is fixed to the groove wall of the first mounting groove 121, the second portion of the vibration transmission member 24 is fixed to the groove wall of the second mounting groove 122, the third portion of the vibration transmission member 24 is located in the third mounting groove 123 without being fixed to the groove wall, and the vibration exciting member 21 is fixed to the third portion of the vibration transmission member 24.
In the implementation, in this mounting manner of the vibration transmission member 24, the vibration transmission member 24 may be divided into three parts, which are respectively referred to as a first part, a second part and a third part, and correspondingly, as shown in fig. 8, the mounting groove 12 may also be divided into three parts, which are respectively referred to as a first mounting groove 121, a second mounting groove 122 and a third mounting groove 123, wherein the three mounting grooves are communicated with each other, and the third mounting groove 123 is located between the first mounting groove 121 and the second mounting groove 122. Thus, the first portion of the vibration transmission member 24 may be fixed to the groove wall of the first mounting groove 121, the second portion of the vibration transmission member 24 may be fixed to the groove wall of the second mounting groove 122, and the third portion of the vibration transmission member 24 may be located in the third mounting groove 123. Wherein the third portion of the vibration transmission member 24 is not fixed to the groove wall of the third mounting groove 123, for example, as shown in fig. 8, the third portion of the vibration transmission member 24 may be suspended in the third mounting groove 123, for example, the third portion of the vibration transmission member 24 is in contact with the groove wall of the third mounting groove 123, and the like. Then, the vibration exciting member 21 may be fixed to the third portion of the vibration transmitting member 24, and since the third portion of the vibration transmitting member 24 is not fixed to the groove wall of the third mounting groove 123, the vibration exciting member 21 may drive the vibration transmitting member 24 to vibrate in the space of the third mounting groove 123, and the vibration is transmitted to the first portion and the second portion of the vibration transmitting member 24, and then transmitted to the groove wall of the mounting groove 12, and finally transmitted to the user.
In one possible application, as described above, in order to save the installation space, the fixing position of the vibration transmission member 24, the fixing position of the wiring board 26, and the fixing position of the touch detection member 23 may correspond accordingly. For example, one mode may be that, as shown in fig. 8, a circuit board 26 mounted with the touch detection part 23 and the control part 22 may be fixed on the first portion or the third portion of the vibration transmission part 24. Alternatively, in order to increase the contact range of the contact detecting member 23, correspondingly, as shown in fig. 9, the vibration module 2 may include two contact detecting members 23 and two circuit boards 26, each of the contact detecting members 23 being mounted on one of the circuit boards 26, a first portion of the vibration transmitting member 24 being fixed to an inner wall of the first mounting groove 121, the circuit board 26 to which the contact detecting member 23 is fixed being fixed to the first portion of the vibration transmitting member 24; a second part of the vibration transmission member 24 is fixed to an inner groove wall of the second mounting groove 122, and the other circuit board 26 to which the touch detection member 23 is fixed to the second part of the vibration transmission member 24; wherein, the detection surfaces of the two touch detection parts 23 are respectively contacted with the outer groove walls of the corresponding mounting grooves.
In the installation manner of the vibration module in the installation groove 12 as shown in fig. 9, the solid line arrows may indicate the touch direction of the user, and the vibration transmission path may be, as shown by the dotted line arrows, transmitted to the second surface 112 of the side wall 11 along the side wall 11 of the middle frame 1 through the inner groove wall of the first installation groove 121 and the inner groove wall of the second installation groove 122, so that the user contacting the second surface 112 of the side wall 11 may feel the vibration.
Alternatively, in order to reduce the vibration transmission route, it is appropriate that, as shown in fig. 10, a vibration feedback part 124 is provided on a groove wall of the third mounting groove 123, and an end of the vibration feedback part 124 remote from the groove wall of the third mounting groove 123 is in contact with the vibration transmission member 24.
The structural shape of the vibration feedback unit 124 is not limited, and vibration transmission may be achieved.
In operation, when the vibration exciting member 21 brings the third portion of the vibration transmitting member 24 to vibrate together, the third portion of the vibration transmitting member 24 transmits the vibration to the second surface 112 through the vibration feedback portion 124, and obviously, in this vibration transmission mode, the transmission path is shorter, and the user can feel the vibration feedback more quickly.
In addition, the vibration feedback part 124 can be integrally formed with the middle frame 1, that is, the vibration feedback part 124 can be a part of the middle frame 1, in this case, energy loss caused by impact or collision between the vibration feedback part 124 and the groove wall of the third mounting groove 123 is avoided.
Alternatively, in order to reduce the energy loss as much as possible, the vibration feedback part 124 may be in point contact with the third portion of the vibration transmission member 24, and accordingly, as shown in fig. 10, the vibration feedback part 124 may have a cylindrical structure, and the end in contact with the vibration transmission member 24 may have a spherical structure.
Alternatively, in order to reduce the occupied space of the vibration feedback part 124, correspondingly, the vibration feedback part 124 may also have a spherical structure, one end of the vibration feedback part 124 of the spherical structure is fixed on the groove wall of the third mounting groove 123, and the other end is in contact with the vibration transmission member 24.
In practice, the end of the vibration feedback part 124 away from the outer groove wall has a spherical structure, and the vibration feedback part 124 is in interference contact with the third part of the vibration transmission member 24, so that the vibration feedback part 124 can always maintain point contact with the third part of the vibration transmission member 24 during the vertical vibration of the third part of the vibration transmission member 24. The point contact can reduce the energy consumed by collision compared with the line contact and the surface contact, because the point contact always keeps the contact surface unchanged in the vibration process, the contact surface is unchanged, namely the contact area is not changed, so that the energy loss can not be generated in the vibration transmission process, and the line contact and the surface contact can change the contact surface in the vibration transmission process, the contact surface is changed, namely the contact area is changed, the impact and the collision can be generated in the contact area changing process, and the collision process can be accompanied with the energy loss. Furthermore, the spherical end of the vibration feedback part 124 contacts the third part of the vibration transmission member 24, which not only shortens the vibration transmission path, but also reduces the energy loss generated during the vibration transmission.
In a possible embodiment, in the case that both ends of the vibration transmission member 24 are fixed to the mounting groove 12, the vibration module 2 may be assembled by a technician assembling the touch detection member 23, the control member 22, and the base plate 261 and the reinforcing steel 262 of the circuit board 26 into an assembly; fixing the vibration exciting member 21 to the third portion of the vibration transmitting member 24 as an assembly; thereafter, the technician can mount the above-described assembly member in the mounting groove 12 in accordance with the positional relationship among the first mounting groove 121, the second mounting groove 122, and the third mounting groove 123.
In the present embodiment, the specific installation manner of the vibration component 2 in the installation groove 12 of the middle frame 1 is not particularly limited, and it is sufficient that the vibration exciting member 21 vibrates in the installation groove 12 and transmits the vibration to the second surface 112 of the side wall 11, and a user in contact with the second surface 112 feels the vibration feedback.
In the disclosed embodiment, the terminal comprises a middle frame, a rear cover and a vibration assembly, wherein the vibration assembly comprises a vibration exciting part, a control part and a touch detection part, wherein: the side wall of the middle frame is provided with an installation groove, the vibration exciting component and the touch detection component are installed in the installation groove, and the detection surface of the touch detection component faces the side wall of the middle frame; the control component is respectively and electrically connected with the vibration exciting component and the touch detection component. According to the virtual key with the vibration feedback, when a user touches the virtual key, the user can feel the vibration feedback, and after the user feels the vibration feedback, the user can determine that the operation is successful without continuously touching, so that the frequency of mistakenly triggering the virtual key by the user can be reduced, and the success rate of operating the virtual key by the user is improved.
The above description is only one embodiment of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
