Description

Electronic device including a display panel speaker {AN ELECTRONIC DEVICE INCLUDING A DISPLAY PANEL SPEAKER}

Various embodiments relate to an electronic device having a display panel speaker.

Recently, a sound on display (SOD) technology capable of generating sound through vibration of a display panel by mounting a vibration actuator on a display of a mobile device is expanding. The SOD technology can implement a full screen of the display panel by removing the existing speaker module including the acoustic radiation channel.

Vibration actuators mainly used to implement SOD include voice coil motors and piezoelectric actuators. By attaching such a vibration actuator to a device of a mobile device, the vibration generated from the vibration actuator is transmitted to the panel display and is converted into an acoustic signal.

In contrast, the display panel speaker may generate sound by mounting a vibration actuator on the rear surface of the display even outside the reference area for receiving/receiving. For this reason, the display panel speaker can secure a high degree of freedom in component mounting unlike the existing speaker module for communication. However, as the position of the vibration actuator is further away from the reference region of the handset, there is a problem that the acoustic performance is deteriorated.

An acoustic signal having a designated frequency for can be generated.

The electronic device according to the various embodiments described above may include a first surface facing a first direction, a second surface facing a second direction opposite to the first direction, and along edges of the first surface and the second surface. A housing including a side surface extending to form an inner space, a support member extending from the side surface of the housing and disposed in the inner space, and including a first region in which at least a portion is dug, a display disposed on the support member, and A vibration actuator disposed between the display and the second surface and disposed within a specified distance from the first region, and a portion of the support member including the first region by vibration generated from the vibration actuator By vibrating at least a portion of the sound signal having a designated frequency for use in voice communication may be generated.

According to various embodiments of the present disclosure, by adjusting the rigidity of a display or support member of an electronic device, acoustic characteristics generated by a vibration actuator may be improved. In particular, it is possible to improve the output of the high-pitched range, and frequency flattening may be possible.

In various embodiments, the vibration actuator arrangement region 601 may not be included in the sound adjustment region 603 as shown in FIG. 11, and unlike the illustration, at least a portion of the vibration actuator arrangement region 603 may overlap.

In various embodiments, the front surface 310A of the electronic device 300 may include a first area 1111 and a second area 1112. The first region 1111 may have a width w and a length d ₂ . The length d ₂ may be half (L/2) of the length L of the electronic device 300. The second area 1112 may have a width w, and the length of the second area 1112 may be Ld ₂ . That is, the first region 1111 and the second region 1112 may be regions obtained by dividing the front surface 310A of the electronic device 300 into two equal parts. Dividing the first region 1111 and the second region 1112 into two is exemplary, and is not limited thereto.

Referring to FIG. 12A, the boundary condition of the stiffness adjustment region 602 may be a square having a horizontal length a and a vertical length b. In this case, the resonance frequency (ω _mn ) of the device of the electronic device 300 through which the vibration can be transmitted by the vibration actuator 400 may be expressed as Equation 1 below. In various embodiments, the device may include at least one of a support member 404, a display 403, and/or a front plate 402.

In Equation 2, E is a Young's modulus of the device, and μ is a Poisson's ratio of the device.

When m=1 and n=1, the primary resonance frequency (ω ₁₁ ) of the apparatus can be expressed as Equation 3 below.

The resonance frequency (ω ₁₁ ) may be determined according to geometrical parameters of the apparatus such as a, b, h, ρ, and μ.

In various embodiments, a geometric parameter of the stiffness adjustment region 602 may be determined according to a frequency band of sound output from the electronic device 300, and acoustic performance (eg, sound pressure, frequency response characteristics) in the frequency band may be determined. It can be improved. For example, when it is assumed that the frequency band for which the acoustic performance is required to be improved is 20 kHz or less, which is a human audible frequency band, the minimum area of the acoustic adjustment area 602 required according to the frequency band (for example, about 100 mm ² ) Can be determined.

Referring to FIG. 12B, the boundary condition of the stiffness adjustment region 602 may be a circular shape having a radius a. In this case, the resonance frequency (ω _mn ) of the apparatus of the electronic device 300 through which vibration can be transmitted by the vibration actuator 400 may be expressed as Equation 4 below.

In Equation 4, ω _mn is the resonance frequency of the device, a is the radius of the rigidity adjustment region 602 formed on the device, h is the thickness of the device, ρ is the density of the device, and E is Is the Young's modulus of the device, μ is the Poisson's ratio of the device, m and n are variables according to the vibration mode of the device, and α _mn is an eigen value according to the boundary condition )to be.

When m = 0 and n = 1, Equation 4 is expressed in terms of the radius (a) of the stiffness adjustment region 602 as Equation 5 below.

Referring to Equation 5, the radius (a) of the stiffness adjustment region 602 may be determined according to a frequency (f _r ) to improve acoustic performance. For example, when it is assumed that the frequency band for which the improvement of acoustic performance is required is less than 20 kHz, which is a human audible frequency band, the minimum radius (a) of the acoustic adjustment region 602 required according to the frequency band may be determined. have. For example, f _r may be 20000 Hz. Α ₀₁ for determining the first resonant frequency ω ₀₁ may vary depending on the boundary condition, but may be about 3.1962 in a clamped condition. In this case, the radius (a) of the stiffness adjustment region 602 may be determined based on the remaining parameters (h, ρ, μ, E) excluding the radius (a) of the apparatus. Since the radius (a) may increase as the frequency (f _r ) is lowered, the determined radius (a) of the stiffness adjustment region 602 is the minimum radius required to improve the acoustic performance of the frequency band of 20 kHz or less. Can be Based on the radius (a), the area of the stiffness adjustment region 602 may be determined. In various embodiments, a minimum area (eg, about 100 mm ² ) of the required stiffness adjustment region 602 may be determined according to a frequency band (eg, 20 kHz or less) in which acoustic performance is required to be improved. For another example, if we assume the band required for the improvement of acoustic performance by up to about 2 kHz over 20 kHz, the area of the required stiffness adjustment area 602 is greater than about 100mm ² can be not more than 4000mm ^2.
