Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 to 6 show a preferred embodiment of the present invention.
The present embodiment provides a speaker assembly 100, and the speaker assembly 100 can be used in any electronic device with sound output function, such as a mobile phone, a tablet, an MP3 player, an MP4 player, a telephone base, an electronic watch, an electronic calculator, etc. Speaker assembly 100 may specifically include a speaker 120 and a cover 110, where speaker 120 is disposed on cover 110 and defines a front sound cavity 123 with cover 110.
The speaker 120 has a first sidewall 121 perpendicular to the upper cover 110 and a first inclined wall 122 opposite to the first sidewall 121, and the first inclined wall 122 is inclined toward the front sound cavity 123. The surface of the upper cover 110 facing the speaker 120 has a second sidewall 113 extending toward the speaker 120 and a second inclined wall 112 opposite to the second sidewall 113, and the second inclined wall 112 is inclined away from the front sound cavity 123.
When speaker 120 is attached to upper cover 110, first side wall 121 of speaker 120 abuts against second side wall 113 of upper cover 110, and first sloped wall 122 of speaker 120 abuts against first sloped wall 122 of upper cover 110. When the speaker 120 is pressed by the speaker 120 toward the upper cover 110, the first inclined wall 122 presses against the second inclined wall 112, and the second inclined wall 112 gives the first inclined wall 122 a reverse thrust, and this thrust can be divided into a first thrust component directed from the upper cover 110 toward the speaker 120 and a second thrust component directed from the second inclined wall 112 toward the second side wall 113 (for convenience of description, the thrust component directed from the second inclined wall 112 toward the second side wall 113 is hereinafter referred to as a second thrust component).
In the prior art, the speaker 120 does not have the first inclined wall 122, the upper cover 110 does not have the second inclined wall 112, and each side wall surface of the speaker 120 is arranged perpendicular to the upper cover 110, so that when the speaker 120 is pressed in a direction close to the upper cover 110, the speaker 120 only gives a positive thrust (a thrust directed from the speaker 120 to the upper cover 110) to the upper cover 110, and no interaction force exists between the speaker 120 and the upper cover 110 on a plane parallel to the upper cover 110. Therefore, the sealing effect between the side wall of the speaker 120 and the upper cover 110 in the prior art is greatly determined by the matching relationship between the speaker 120 and the upper cover 110, and when the dimensional error of the speaker 120 is large and small during manufacturing, the sealing performance between the side wall of the speaker 120 and the upper cover 110 is poor, so that the front sound cavity 123 and the rear sound cavity 1111 of the speaker assembly 100 are communicated, thereby affecting the overall sound quality of the speaker assembly 100.
In the present embodiment, by providing the first inclined wall 122 on the speaker 120 and the second inclined wall 112 on the upper cover 110, the pressure of the speaker 120 based on the upper cover 110 is converted into the pressure between the side wall of the speaker 120 and the upper cover 110, so that the sealing effect between the side wall of the speaker 120 and the upper cover 110 is enhanced, the front sound cavity 123 and the rear sound cavity 1111 of the speaker assembly 100 are prevented from communicating, and the sound quality of the speaker assembly 100 is improved.
In order to achieve a better fitting relationship of the speaker 120 and the upper cover 110, the first inclined wall 122 of the speaker 120 may be disposed in parallel with the second inclined wall 112 of the upper cover 110. The angles of inclination of the first inclined wall 122 and the second inclined wall 112 can be adjusted according to actual requirements. When a larger second partial thrust force is required, the inclination angles of the first inclined wall 122 and the second inclined wall 112 (which refers to the included angle between the plane of the first inclined wall 122 and the plane of the first side wall 121, i.e., the angle M shown in fig. 5) can be adjusted to be smaller within a certain range, and when a smaller second partial thrust force is required, the inclination angles of the first inclined wall 122 and the second inclined wall 112 can be adjusted to be larger within a certain range. In this embodiment, an included angle between a plane of the first inclined wall 122 and a plane of the first side wall 121 is [20 °, 30 ° ], for example, the angle M may be 20 °, 25 °, or 30 °.
To enhance the sealing effect between the speaker 120 and the upper cover 110, the speaker assembly 100 may further include a first sealing member 130. The first sealing member 130 has a ring shape, the upper cover 110 includes a bottom wall facing the speaker 120 between the second sloped wall 112 and the second side wall 113, and one surface of the first sealing member 130 is bonded to the bottom wall of the upper cover 110 and the other surface is bonded to a surface wall of the speaker 120 facing the bottom wall. And the first sealing member 130 defines the front sound chamber 123 together with the upper cover 110 and the speaker 120. The first sealing member 130 ensures the sealing effect between the speaker 120 and the upper cover 110, and increases the space of the front sound cavity 123 to improve the sound quality of the speaker assembly 100.
In particular, as shown in fig. 2 or 4, in the present embodiment, the first seal 130 extends from the first sloped wall 122 to the bottom wall. That is, the first inclined wall 122 and the second inclined wall 112 are not in direct contact, but are abutted by the first seal 130. Since the first sealing member 130 is annular, a certain space is also provided between the first inclined wall 122 and the second inclined wall 112, and the space is communicated with the front sound cavity 123, so that the front sound cavity 123 of the loudspeaker 120 is larger in space. Moreover, when the space between the first inclined wall 122 and the second inclined wall 112 is added, the space between the bottom wall of the upper cover 110 and the speaker 120 can be properly reduced, which enables the thickness of the speaker assembly 100 in the direction perpendicular to the upper cover 110 to be properly reduced, thereby enabling the overall thickness of the electronic device to be reduced.
When the first sealing member 130 extends from the second inclined wall 112 to the bottom wall of the upper cover 110, in order to buffer the pressure given to the second inclined wall 112 by the speaker 120, the first sealing member 130 may have elasticity, and in particular, the first sealing member 130 may be foam rubber having elasticity. This is so that when speaker 120 is pressed against second sloped wall 112, first seal 130 may further seal front sound cavity 123 by elastically deforming.
In one embodiment, in order to make the transition between the second inclined wall 112 of the upper cover 110 and the bottom wall of the upper cover 110 smoother, the second inclined wall 112 of the upper cover 110 may have a circular arc transition with the bottom wall. When the second inclined wall 112 of the upper cover 110 may form an arc transition with the bottom wall, the first sealing member 130 may better extend from the second inclined wall 112 to the bottom wall, and a gap at an angular end of the first sealing member 130 between the second inclined wall 112 and the bottom wall is prevented from occurring, so that the sealing effect of the front sound cavity 123 is reduced.
The electronic device may be a mobile phone, and the following description will be made of the electronic device to which the present application is applied by taking the mobile phone as an example. In the embodiment of the present application, the mobile phone may include a radio frequency circuit, a memory, an input unit, a wireless fidelity (WiFi) module, a display unit, a sensor, an audio circuit, a processor, a projection unit, a shooting unit, a battery, and other components.
The radio frequency circuit can be used for receiving and sending signals in the process of receiving and sending information or calling, and particularly, the radio frequency circuit receives the downlink information of the base station and then processes the downlink information; in addition, the uplink data of the mobile phone is sent to the base station. Typically, the radio frequency circuitry includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, and the like. In addition, the radio frequency circuitry may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Message Service (SMS), and the like.
The memory can be used for storing software programs and modules, and the processor executes various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory. The memory can mainly comprise a program storage area and a data storage area, wherein the program storage area can store an operating system, application programs (such as a sound playing function and an image playing function) required by at least one function and the like; the storage data area may store data (e.g., audio data, a phonebook, etc.) created according to the use of the cellular phone, etc. Further, the memory may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.
The input unit may be used to receive input numeric or character information and generate key signals related to user settings and function control of the cellular phone. Specifically, the input unit may include a touch panel and other input devices. The touch panel, also called a touch screen, may collect touch operations of a user (for example, operations of the user on or near the touch panel using any suitable object or accessory such as a finger, a stylus, etc.) and drive the corresponding connection device according to a preset program. Alternatively, the touch panel may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor, and can receive and execute commands sent by the processor. In addition, the touch panel may be implemented in various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit may include other input devices in addition to the touch panel. In particular, other input devices may include, but are not limited to, one or more of a physical keyboard, keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
The display unit may be used to display information input by a user or information provided to the user, and various menus of the mobile phone, among others. The Display unit may include a Display panel, and optionally, the Display panel may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel may cover the display panel, and when the touch panel detects a touch operation thereon or nearby, the touch panel transmits the touch operation to the processor to determine the type of the touch event, and then the processor provides a corresponding visual output on the display panel according to the type of the touch event.
The position in the visual output external display panel that can be recognized by the human eye may be referred to as a "display region" as described below. The touch panel and the display panel can be used as two independent components to realize the input and output functions of the mobile phone, and the touch panel and the display panel can be integrated to realize the input and output functions of the mobile phone.
In addition, the handset may also include at least one sensor, such as an attitude sensor, a light sensor, and other sensors.
Specifically, the attitude sensor may also be referred to as a motion sensor, and as one of the motion sensors, a gravity sensor may be cited, which uses an elastic sensing element to make a cantilever-type displacer and uses an energy storage spring made of the elastic sensing element to drive an electrical contact, thereby realizing conversion of a change in gravity into a change in an electrical signal.
Another example of the motion sensor is an accelerometer sensor, which can detect the magnitude of acceleration in each direction (generally, three axes), detect the magnitude and direction of gravity when stationary, and can be used for applications for recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like.
The motion sensor listed above may be used as an element for obtaining the "attitude parameter" described later, but the present invention is not limited thereto, and other sensors capable of obtaining the "attitude parameter" fall within the protection scope of the present application, for example, a gyroscope and the like, and the operation principle and data processing procedure of the gyroscope may be similar to those of the prior art, and the detailed description thereof is omitted here for avoiding redundancy.
In addition, as the sensor, other sensors such as a barometer, a hygrometer, a thermometer, and an infrared sensor may be further configured, which are not described herein again.
The light sensor may include an ambient light sensor that adjusts the brightness of the display panel according to the brightness of ambient light, and a proximity sensor that turns off the display panel and/or the backlight when the mobile phone is moved to the ear.
The audio circuitry, speaker 120 and microphone may provide an audio interface between the user and the handset. The audio circuit can transmit the received electrical signal converted from the audio data to the loudspeaker 120, and the electrical signal is converted into a sound signal by the loudspeaker 120 and output; on the other hand, the microphone converts the collected sound signal into an electric signal, the electric signal is received by the audio circuit and then converted into audio data, and the audio data is processed by the audio data output processor and then sent to another mobile phone through the radio frequency circuit or output to the memory for further processing.
WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through a WiFi module, and provides wireless broadband internet access for the user.
The processor is a control center of the mobile phone, is connected with each part of the whole mobile phone by various interfaces and lines, and executes various functions and processes data of the mobile phone by running or executing software programs and/or modules stored in the memory and calling the data stored in the memory, thereby carrying out the integral monitoring on the mobile phone. Alternatively, the processor may include one or more processing units; preferably, the processor may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.
It will be appreciated that the modem processor described above may not be integrated into the processor.
Also, the processor may perform the same or similar functions as the processing unit as the implementation elements of the processing unit.
The handset also includes a power source (such as a battery) to power the various components.
The power supply can be logically connected with the processor through the power management system, so that the functions of managing charging, discharging, power consumption management and the like are realized through the power management system. Although not shown, the mobile phone may further include a bluetooth module, etc., which will not be described herein.
The handset in this embodiment includes the speaker assembly 100 of any of the embodiments described above. Specifically, the speaker assembly 100 includes a speaker 120 and a cover 110, the cover 110 and the speaker 120 together define a front sound cavity 123, whereas the speaker assembly 100 does not have a prior art back cover (in the prior art, the speaker 120 and the back cover together define a back sound cavity 1111), and the speaker 120 and a middle frame of the handset together define a back sound cavity 1111. The structure of omitting the rear cover can reduce the space occupied by the speaker assembly 100 and can also increase the space of the rear sound cavity 1111, improving the bass performance of the speaker assembly 100.
The upper cover 110 of the speaker 120 may be connected to the middle frame of the mobile phone or to a battery cover of the mobile phone, and when the upper cover 110 is connected to the battery cover, the upper cover 110 and the battery cover may be integrally formed. When the top cover 110 is connected to the middle frame of the mobile phone, as shown in fig. 1 to 2, the surface of the top cover 110 facing the middle frame may further be formed with a circumferential wall 111 extending toward the middle frame, the wall 111 is disposed around the periphery of the speaker 120, the wall 111 abuts against the middle frame, and the rear sound cavity 1111 is defined in the space surrounded by the wall 111. Since the speaker 120 and the middle frame of the mobile phone define the back sound cavity 1111, theoretically, any gap between the middle frame of the mobile phone and the battery cover can be called as the back sound cavity 1111 of the mobile phone, and when the sound generated by the speaker 120 escapes to a position where the structure of the mobile phone is complicated, the sound is reflected and interfered for many times at the position, thereby causing sound distortion. The enclosure wall 111 can better prevent the sound generated by the speaker 120 from escaping to a part of the mobile phone with a more complex structural arrangement, and the back sound cavity 1111 is limited in a relatively regular space, so that the bass effect of the speaker 120 is improved.
Specifically. In order to enhance the sealing effect between the surrounding wall 111 and the middle frame, a second sealing member 140 is disposed between the surrounding wall 111 and the middle frame, the second sealing member 140 is annular, one surface of the second sealing member 140 is bonded to the middle frame, the other surface of the second sealing member is bonded to the surrounding wall 111, and the second sealing member 140 is used for sealing the rear sound cavity 1111.
The same or similar reference numerals in the drawings of the present embodiment correspond to the same or similar components; in the description of the present application, it is to be understood that if there is an orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of description, but it is not intended to indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and are not to be construed as limitations of the present patent, and specific meanings of the above terms may be understood by those skilled in the art according to specific situations.
