The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.

As shown in fig. 1, the present disclosure discloses an electronic device 10, the electronic device 10 comprising a sound emitting assembly 100 for emitting sound. In the present embodiment, the electronic device 10 is a mobile phone. A cellular phone typically has two sets of sound generating components, with sound generating component 100 located at the top of electronic device 10 acting as a handset and sound generating component 100 located at the bottom of electronic device 10 acting as a speaker. Of course, in other embodiments, the handset may have only the sound emitting assembly 100 on the top or on the bottom. Alternatively, the electronic device 10 may be another device with the sound emitting assembly 100, such as: computers, tablets, e-books, watches, headsets, etc.

The electronic device 10 further includes a device bezel 200, and the sound generating assembly 100 is disposed inside the device bezel 200. The device middle frame 200 can start supporting and protecting functions for the sound production assembly 100 and other electronic parts.

As shown in fig. 2, in the present embodiment, the sound emitting assembly 100 includes a control chip 110, an audio decoding chip 120, a power amplifier 130, and a sound emitter 140. The control chip 110 is electrically connected to the audio decoding chip 120 to provide the audio decoding chip 120 with a digital audio signal, which is a digital signal. The audio decoding chip 120 receives the digital audio signal and converts the audio signal into an analog audio signal, which is an electrical signal. The audio decoder is electrically connected to the power amplifier 130 to provide an analog audio signal, which is weak, to the power amplifier 130. The power amplifier 130 receives and amplifies the weak analog audio signal. The power amplifier 130 is electrically connected to the sound emitter 140 to provide the amplified electrical signal to the sound emitter 140.

The power amplifier 130 includes a first drive port 131 and a second drive port 132. The voltage signals of the first and

second drive ports

131 and 132 are different. In the present embodiment, the voltage signal of the first driving port 131 is greater than the voltage signal of the second driving port 132. The sound emitter 140 includes a first electrical signal port 141 and a second electrical signal port 142. The first drive port 131 is electrically connected to the first electrical signal port 141 and the second drive port 132 is electrically connected to the second electrical signal port 142, thereby causing current to be generated in the microphone 140. Through the arrangement, the power amplifier 130 and the sound emitter 140 are communicated, so that the power amplifier 130 and the sound emitter are communicated to form a loop and generate current. The sound generator 140 further comprises a magnet and a coil, the coil rotates under the condition of being electrified and generates magnetism, and the coil and the magnet with magnetism are attracted and separated to generate vibration so as to enable the sound generator 140 to generate sound. In this process, if the sound loudness of the sound emitter 140 needs to be raised, the current needs to be raised. However, since each component has a certain resistance, when the current rises, the temperature of the power amplifier 130 and the speaker 140 and the circuit connecting the two also rises. When the temperature generated on the sound emitter 140 exceeds the maximum temperature that it can withstand, there is a risk that the sound emitter 140 will burn out.

In one design, a fuse is connected in series with the circuit connecting the power amplifier 130 and the sound emitter 140, and when the temperature is too high, the fuse is blown, so that the connection between the power amplifier 130 and the sound emitter 140 is cut off, and the sound emitter 140 is protected.

However, in such a design, once the fuse is blown due to the over-high temperature, although a certain protection effect can be provided for the sound emitter 140, when the temperature returns to the normal range, the reconnection between the power amplifier 130 and the sound emitter 140 cannot be realized. If the user needs to use the electronic device 10 normally, the electronic device 10 needs to be repaired and replaced with a new fuse. This process is cumbersome and increases maintenance costs.

In the present embodiment, in order to solve the above problem, as shown in fig. 3 to 5, a control circuit 300 is provided in the sound emitting module 110. The control circuit 300 communicates the power amplifier 130 and the sound emitter 140.

The control circuit 300 includes a first conductive terminal 310, a second conductive terminal 320, and a spring plate 330. The first conductive terminal 310 is electrically connected to one of the power amplifier 130 or the speaker 140 and the second conductive terminal 320 is electrically connected to the other of the power amplifier 130 or the speaker 140. In the above embodiment, the first conductive terminal 310 is electrically connected to the power amplifier 130, and the second conductive terminal 320 is electrically connected to the sound emitter 140. Of course, in other embodiments, the first conductive terminal 310 may be electrically connected to the speaker 140, and the second conductive terminal 320 may be electrically connected to the power amplifier 130.

The elastic piece 330 includes a fixed end 331 and a free end 332. The fixed end 331 is always fixedly connected to the second conductive end 320. The spring 330 is switchable between a closed position 333 and a disengaged position 334. As shown in fig. 3, when the resilient tab 330 is in the closed position 333, the resilient tab 330 abuts against the first conductive terminal 310. As shown in fig. 4 and 5, when the resilient tab 330 is located at the separation position 334, the resilient tab 330 is separated from the first conductive terminal 310. Through the arrangement, the elastic sheet 330 can be switched between the closed position 333 and the separated position 334, when the current in the control circuit 300 is too large, and the temperature is too high, the elastic sheet 330 can be switched from the closed position 333 to the separated position 334, the electrical connection relationship between the power amplifier 130 and the elastic sheet 330 is disconnected, the sound emitter 140 stops working, the phenomenon that the sound emitter 140 is burnt due to the too high temperature is avoided, the overheating protection effect on the sound emitter 140 is achieved, and the service life of the sound emitter 140 is prolonged. When the current in the control circuit 300 falls within the normal range, the temperature of the control circuit 300 returns to the normal range, the elastic piece 330 is switched to the closed position 333 again, the power amplifier 130 and the elastic piece 330 recover the electrical connection relationship, and the sound emitter 140 returns to the normal working position.

In the embodiment, the elastic sheet 330 is made of a memory alloy, and particularly, the elastic sheet 330 may be made of a titanium-nickel alloy material. The elastic sheet 330 made of the material can present two different forms under the change of temperature. The designer can change the performance of the elastic sheet 330 in the stage of manufacturing the elastic sheet 330, so that when the temperature of the elastic sheet 330 is higher than a first preset temperature, the initial state is switched to a changing state; when the elastic temperature is lower than the second preset temperature, the shape is restored to the initial shape. The designer can design the first preset temperature according to the highest temperature that the sound emitter 140 can withstand, and at the same time, can design the second preset temperature according to the temperature at which the sound emitter 140 is normally used. For example, in the present embodiment, the maximum temperature that the sound emitter 140 can bear is 110 ℃, and then the first preset temperature may be 110 ℃ or may be a value slightly lower than 110 ℃. The temperature of the sound emitter 140 during normal use is 60 c or less than 60 c, and then the second preset temperature is 60 c. When the current in the control circuit 300 is too large, so that the temperature on the elastic sheet 330 reaches 110 ℃, the elastic sheet 330 is switched to the changed state, that is, the elastic sheet 330 is switched to the separation position 334, the elastic sheet 330 is disconnected from the first conductive terminal 310, the sound emitter 140 cannot be supported by the electric power, and the temperature drops. When the temperature drops to 60 ℃, the elastic sheet 330 is switched to the initial state, that is, the elastic sheet 330 is switched to the closed position 333, the elastic sheet 330 is electrically connected to the first conductive terminal 310 again, and the sound emitting device 140 is supported by the electric power and works normally. Through the arrangement, the sound generator 140 can be prevented from being burnt out, and the sound generator 140 can be recovered to be normally used when the temperature is reduced to a safe range.

As shown in fig. 3 to 5, the number of the control circuits 300 is two. A control circuit 300 is used to connect the first drive port 131 of the power amplifier 130 and the first electrical signal port 141 of the sound outlet 140. A further control circuit 300 is used to connect the second drive port 132 of the power amplifier 130 and the second electrical signal port 142 of the sound emitter 140. In other words, the first driving port 131 and the first electrical signal port 141 are controlled by the elastic sheet 330. The distance between the second driving port 132 and the second electrical signal port 142 can also be controlled by the elastic sheet 330. Through the arrangement, the problem of impedance mismatch caused by the fact that the elastic sheet 330 is arranged only on the passage of the first driving port 131 and the first electric signal port 141 or the elastic sheet 330 is arranged only on the passage of the second driving port 132 and the second electric signal port 142 can be avoided, and therefore a certain interference prevention effect is achieved.

Of course, in other embodiments, the number of the control circuit 300 may be only one, and the first driving port 131 and the first electrical signal port 141 are electrically connected through the control circuit 300. In other words, the first driving port 131 and the first electrical signal port 141 are controlled by the elastic sheet 330. Alternatively, the second driving port 132 and the second electrical signal port 142 are electrically connected through the control circuit 300, in other words, the second driving port 132 and the second electrical signal port 142 are controlled by the elastic piece 330. Through the arrangement, the sound generator 140 can be prevented from being burnt out, and meanwhile, when the temperature is reduced to be within a safe range, the sound generator 140 can be recovered to be normally used.

As shown in fig. 6, the sound generating assembly 100 further includes a first circuit board 340, the first circuit board 340 is at least a part of the control circuit 300, and the second conductive terminal 320 is disposed on the first circuit board 340. In other words, the second conductive terminal 320 may be integrated with the first circuit board 340, or a pad or solder joint on the first circuit board 340 may be used as the second conductive terminal 320. One of the sound emitter 140 or the power amplifier 130 is connected to the first circuit board 340, and the fixed end 331 of the elastic piece 330 is fixedly connected to the first circuit board 340. The first circuit board 340 is arranged to facilitate the electrical connection between the elastic sheet 330 and the second conductive terminal 320.

The sound emitting assembly 100 may further include a second circuit board 350, the second circuit board 350 being at least a portion of the control circuit 300, and the first conductive terminal 310 being disposed on the second circuit board 350. In other words, the first conductive terminal 310 may be integrated with the second circuit board 350, or a pad or solder joint on the second circuit board 350 may be used as the first conductive terminal 310. The other of the speaker 140 or the power amplifier 130 is connected to the second wiring board 350. When the spring plate 330 is in the closed position 333, the spring plate 330 contacts the second circuit board 350. When the elastic sheet 330 is located at the separating position 334, the elastic sheet 330 and the second circuit board 350 are spaced apart. Through the arrangement, the area of the first conductive end 310 can be increased, so that when the elastic sheet 330 is located at the closed position 333, the contact area between the elastic sheet 330 and the first conductive end 310 is favorably increased, and the electrical connection relationship is ensured. In the present embodiment, the second wiring board 350 may be a flexible wiring board.

As shown in fig. 6, the elastic sheet 330 further includes a welding portion 335, the welding portion 335 is disposed on an outer wall of the fixing end 331, and the welding portion 335 is welded and fixed to the first circuit board 340. When the elastic sheet 330 needs to be fixed on the first circuit board 340 by welding, the memory alloy material has the characteristic of poor solder resistance, so that the elastic sheet 330 and the first circuit board 340 are not easy to be firmly connected. By providing the soldering portion 335, it is advantageous to realize the fixed connection between the soldering portion 335 and the first circuit board 340. In the present embodiment, the material of the welding portion 335 is copper, iron, or the like. The soldering portion 335 may be formed by electroplating on the outer wall of the fixed end 331 through an electroplating process.

Further, as shown in fig. 3 to 8, the first conductive terminal 310 and the second conductive terminal 320 are spaced apart in the first direction X. The first conductive terminal 310 and the second conductive terminal 320 are electrically connected in the first direction X by the spring plate 330.

In one embodiment, as shown in fig. 3-5, the elastic sheet 330 includes an abutting portion 337, a connecting portion 338 and a fixing portion 339. The abutment 337 as a free end 332; the two ends of the connecting part 338 are respectively connected with the fixing part 339 and the abutting part 337; the fixing portion 339 serves as a fixing end 331 and is fixedly connected to the second conductive end 320. Wherein the plane on which the abutting portion 337 is located is parallel to the plane on which the second conductive terminal 320 is located. As shown in fig. 3, when the resilient tab 330 is located at the closed position 333, the abutting portion 337 abuts against the first conductive end 310, and a plane of the abutting portion 337 coincides with a plane of the second conductive end 320, so as to ensure a larger contact area exists between the two. As shown in fig. 4 and 5, when the elastic piece 330 is located at the separation position 334, the abutting portion 337 and the first conductive terminal 310 are spaced in the first direction X. With the above arrangement, the contact area between the free end 332 and the second conductive terminal 320 can be increased, so that when the elastic piece 330 is located at the closed position 333, a stable electrical connection relationship between the elastic piece 330 and the second conductive terminal 320 is ensured.

When the spring plate 330 is in the closed position 333, the connecting portion 338 has a component in the first direction X (shown with reference to fig. 3). With the above arrangement, the connecting portion 338 enables the elastic sheet 330 to connect the first conductive terminals 310 and the second conductive terminals 320 arranged at intervals in the first direction X. When the resilient tab 330 is located at the separation position 334, the connecting portion 338 may still have a component in the first direction X (as shown in fig. 4), or the planes in which the connecting portion 338, the abutting portion 337 and the fixing portion 339 are located may coincide (as shown in fig. 5).

In another embodiment, as shown in fig. 7 and 8. At least a portion of the resilient piece 330 is raised in the first direction X near the first conductive terminal 310, and forms a raised portion 336, and the raised portion 336 serves as the free end 332. As shown in fig. 7, when the spring 330 is in the closed position 333, the bump 336 abuts against the first conductive terminal 310. As shown in fig. 8, when the resilient tab 330 is located at the separation position 334, the bump portion 336 and the first conductive terminal 310 are spaced apart in the first direction X.

Further, as shown in fig. 3-5, 7 and 8, the sound generating assembly 100 further includes two electrical signal sensors 360, in this embodiment, the number of the electrical signal sensors 360 is two. An electrical signal sensor 360 is connected to both the first drive port 131 and or the second drive port 132. When the electrical signal sensor 360 is used to detect at least one of the following signals: current signal, voltage signal, ratio signal of current signal and voltage signal. When the signal detected by the electrical signal sensor 360 is greater than the predetermined value or less than the predetermined value, it indicates that the current flowing through the control circuit 300 is too high, the temperature of the sound emitter 140 is too high, and there is a wind direction that is burned. At this time, the control chip 110 controls the magnitude of the current flowing through the sound emitter 140 to protect the sound emitter 140. When the control of the control chip 110 is in error, the elastic sheet 330 can still protect the sound emitter 140. With the above arrangement, the dual protection of the speaker 140 can be realized in both software and hardware.

Although the present disclosure has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure.
