In the course of researching sound production schemes suitable for various forms of mobile phones, the inventor of the present disclosure recognizes that the speaker in the related art constitutes a certain limitation on the design of the form of the mobile phone. In the scheme exploration for realizing sound production by adopting piezoelectric ceramics, the piezoelectric ceramics are tried to be fixed on a middle frame of a mobile phone, sound wave vibration is transmitted by the contact of the mobile phone and a human body, and the whole middle frame is driven to vibrate and produce sound. If the audio exciter is fixed on the screen of the mobile phone, the vibration is directly transmitted to the screen and drives the screen to vibrate, and the screen replaces the traditional loudspeaker diaphragm, so that the requirement on the strength of the whole mobile phone by the screen exciter is found to be high. The inventors have made studies to propose an electronic apparatus of an embodiment of the present disclosure, with recognition of the above-described problems.
An electronic device 10 according to an embodiment of the present disclosure is described below with reference to the drawings.
Fig. 1 is a schematic structural diagram of an electronic device 10 according to an embodiment of the disclosure. As shown in fig. 1, an electronic device 10 according to an embodiment of the present invention includes a housing 11, a piezoelectric sound generating device 12, and a vibration space 16. The piezoelectric sound generating device 12 is disposed on an inner surface (left surface in fig. 1) of the housing 11 and electrically connected to a control circuit board 13 disposed in the electronic apparatus. The vibration space 16 is provided between a side of the piezoelectric sound generating device 12 remote from the housing 11 (the right side in fig. 1) and an internal device 19 of the electronic apparatus. The piezoelectric sound generating device 12 generates sound by vibration in the vibration space 16 based on the circuit control of the control circuit board 13.
It is understood that the electronic device 10 according to the embodiment of the present disclosure, in addition to the housing 11, the piezoelectric sound generating device 12 and the control circuit board 13, the internal device 19 may be any other component inside the electronic device, and the specific device of the internal device 19 may be any device that can be set for a specific application.
As shown in fig. 1, in the present embodiment, the vibration space 16 is disposed between the right side of the piezoelectric sound generating device 12 far away from the casing 11 and the left side of the internal device 19 close to the casing 11, in other words, the vibration space 16 is left between the piezoelectric sound generating device 12 and the internal device 19, and the piezoelectric sound generating device 12 vibrates and generates sound in the vibration space 16 under the circuit control of the control circuit board 13.
According to the electronic equipment disclosed by the embodiment of the disclosure, the piezoelectric sound generating device is arranged on the inner surface of the shell, the piezoelectric sound generating device realizes sound wave transmission through vibration in the vibration space, and is not required to be additionally fixed or attached to other parts, so that the electronic equipment can be suitable for more new forms of electronic equipment, and the electronic equipment is not limited in form design and is more flexible and free.
In some embodiments, as shown in fig. 1 and 2, the electronic device 10 also includes a curved screen 18.

In some embodiments, the at least one side of the electronic device 10 comprises a side screen of the curved screen 18, i.e. a side portion of the curved screen 18 constitutes at least one side of the electronic device.
Optionally, at least one side of the electronic device 10 includes a side screen of the curved screen 18 and a side housing of the housing 11, which are connected, and the side housing means that the housing constitutes a side portion of the electronic device, in other words, the side screen of the curved screen 18 and the side housing of the housing 11 which are connected constitute at least one side of the electronic device. As shown in fig. 1, the lower side housing portion of the housing 11 meets the lower side screen portion of the curved screen 18 to form the underside of the electronic device. Alternatively, in fig. 1, if the housing 11 does not have a lower side housing portion, the lower side screen portion of the curved screen 18 constitutes the lower side of the electronic device.
As can be seen from the above embodiments, the electronic device 10 may be a four-curved-surface electronic device, or may be any surround-screen electronic device.
As shown in fig. 1, when the housing 11 has a side housing portion, i.e. the housing 11 has a back plate and side plates, preferably, the piezoelectric sound generating device 12 is disposed on the inner surface of the back plate of the housing 11.
As shown in fig. 3, the piezoelectric sound generating device 12 may be disposed on the inner surface of the housing 11 by adhesion, for example, silicon gel or other adhesive may be used, as long as the piezoelectric sound generating device 12 can be fixed on the inner surface of the housing 11. The piezoelectric sound production device 12 is fixed on the inner surface of the shell 11 in an adhesion mode, so that the processing and assembling difficulty is reduced, the shape adaptability of the electronic equipment is stronger, the piezoelectric sound production device is particularly suitable for the electronic equipment shape with a screen or a side middle frame or a narrow shell, the piezoelectric sound production device is also suitable for the appearance requirement of the whole machine without holes, the waterproof and dustproof effects of the whole machine are more easily realized, and the like. Meanwhile, the piezoelectric sound-generating device 12 is arranged in the cavity and attached to the inner surface of the shell, which can also be called as the inner surface of the back plate of the shell, and can be arranged and adjusted according to the structural positions of other devices, so that the great freedom degree of selection of the piezoelectric sound-generating device on the structural arrangement is realized.
In some embodiments, the inner surface of the casing 11 may be provided with a groove, and the piezoelectric sound generating device 12 is disposed at the groove, thereby taking into account the overall layout of other devices of the electronic equipment, and in case that the casing 11 is thick or in order to avoid the internal device 19, the vibration space 16 required for the piezoelectric sound generating device 12 to vibrate and generate sound can be ensured.
In some embodiments, the piezoelectric sound generating device 12 is disposed on the inner surface of the housing 11, and the piezoelectric sound generating device 12 may be a piezoelectric ceramic diaphragm, a piezoelectric thin film, or a combination thereof. The piezoelectric sound generating device 12 may be disposed on the inner surface of the casing 11 in various ways, for example, a piezoelectric ceramic membrane may be disposed on the inner surface of the casing 11, a piezoelectric thin film may be disposed on the inner surface of the casing, the piezoelectric thin film and the piezoelectric ceramic membrane may be stacked, the stacked piezoelectric thin film and the piezoelectric ceramic membrane may be attached to the inner surface of the casing, the piezoelectric thin film and the piezoelectric ceramic membrane may be disposed adjacent to each other on the inner surface of the casing 11, or any combination thereof.
As shown in fig. 4, in some embodiments, the electronic device 10 further comprises a resilient support 17. For example, a resilient support 17 may be provided on the inner surface of the housing 11 for supporting the piezoelectric sound generating device 12.
The elastic support member 17 supports the piezoelectric sound generating device 12, so that a buffering effect can be achieved in the vibration process of the piezoelectric sound generating device 12, and the piezoelectric sound generating device 12 is prevented from loosening due to vibration.
In some embodiments, the material of the elastic supporting member 13 is an elastic buffer material, such as foam, silica gel, or a mixture/combination of these two materials, which is not limited in particular.
In some embodiments, the piezoelectric sound producing device 12 is located at a symmetrical position to at least one pair of opposing sides of the electronic device. For example, in fig. 3, the piezoelectric sound production device 12 may be located at the center of the electronic apparatus in the left-right direction and/or at the center of the electronic apparatus in the up-down direction.
Alternatively, the symmetrical positions of the opposite sides of the electronic device include not only the center of the opposite sides of the electronic device, but also positions within a preset range of a predetermined distance from the center toward the opposite sides with the axis of symmetry of the opposite sides of the electronic device as the center, for example, in fig. 3, the piezoelectric sound generating device 12 may be deviated from the center of the electronic device in the left-right direction by a certain distance and/or deviated from the center of the electronic device in the up-down direction by a certain distance, and these positions deviated from the center by a certain distance are also referred to as symmetrical positions on the opposite sides in this embodiment. The piezoelectric sounding device 12 is arranged at the center of the symmetrical axis of the opposite side surfaces of the electronic equipment, so that the uniformity of vibration sounding can be improved, and the effect of sound effect propagation can be improved.
In other embodiments, as shown in fig. 3, the piezoelectric sound device 12 may be disposed adjacent a side edge of the housing 11, such as the piezoelectric sound device 12 is disposed adjacent a lower side edge of the housing. Therefore, when the electronic device is used, the sound production of the piezoelectric sound production device 12 is not easily influenced by the user holding the electronic device, and the sound production effect is improved.
In some embodiments, the side of the piezoelectric sound production device 12 may be provided with a conductive interface, which is electrically connected with the control circuit board 13. Alternatively, a gold-plated PAD may be provided as a conductive interface, the gold-plated PAD being electrically connected to the control circuit board 13. The connection between the gold-plated PAD and the circuit board can be realized by the elastic sheet arranged on the control circuit board 13, so that the connection reliability with the control circuit board 13 is not affected when the piezoelectric sound generating device 12 vibrates.
In some embodiments, the piezoelectric sound generating device 12 is stacked on the electronic device structure, and optionally, an avoidance design is performed with a module having a relatively thick thickness in consideration of space and other factors, for example, a camera module, a battery and other relatively thick devices, and the piezoelectric sound generating device 12 may be considered to avoid them on the position stack, that is, the projection position on the housing 11 is set to be avoided from the projection position of the camera module 15 of the electronic device on the housing 11, and/or the projection position of the piezoelectric sound generating device 12 on the housing 1 is set to be avoided from the projection position of the battery module 14 of the electronic device on the housing 11, and the like.
