It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
The buzzer is widely used in electronic devices such as computers, printers, copiers, alarms, electronic toys, telephones, timers, and the like. However, the manner in which the buzzer is used by the electronic device provided by the related art is simpler, resulting in fewer functions of the electronic device. For example, these electronic devices use a sound producing function of a buzzer, but do not use a vibration detecting function of a buzzer, resulting in the electronic devices having no vibration detecting capability although having sound producing capability.
In view of this, the embodiment of the application provides a sound generating device. The sounding device comprises a buzzer and a control component connected with the buzzer. The control component can output a driving voltage to the buzzer, so that the buzzer sounds based on the driving voltage. The buzzer may also output a first voltage to the control component in case of detecting a vibration, such that the control component is able to determine the vibration intensity of the buzzer from the first voltage. The sound generating device provided by the embodiment of the application has both sound generating function and vibration intensity detection function, so that the functions of the electronic equipment can be enriched, and the electronic equipment has the sound generating function and the vibration intensity detection function.
The sounding device provided by the embodiment of the application can be applied to electronic equipment such as computers, printers, copiers, alarms, electronic toys, telephones, timers and the like.
For example, in one scenario example, the electronic device outputs a driving voltage to the buzzer through a control component in the sound generating device, so that the buzzer generates sound, and a sound generating function is realized. Under the condition that the buzzer detects vibration, the electronic equipment detects the first voltage through the control component and determines the vibration intensity of the buzzer according to the first voltage, so that the vibration intensity detection function is realized.
In order to illustrate the technical solution of the present application, the following description will use the application of the sound generating device to the electronic device as an example, and will be made by way of specific embodiments.
Fig. 1 shows a schematic structural diagram of a sound generating apparatus according to an embodiment of the present application, and for convenience of explanation, only a portion related to the present embodiment is shown.
As shown in fig. 1, the sound generating device includes a buzzer 10 and a control unit 20 connected to the buzzer 10. The control assembly 20 has a first output 201 and a second output 202. The control assembly 20 is configured to output a driving voltage to the buzzer 10 through the first output terminal 201 and the second output terminal 202. The buzzer 10 is used to sound based on the driving voltage, thereby realizing a sound emitting function.
The buzzer 10 is also used to output a first voltage in case of vibration detection. The control assembly 20 is further configured to detect the first voltage through the first output terminal 201 and the second output terminal 202, and determine the vibration intensity of the buzzer 10 according to the first voltage, thereby implementing a vibration intensity detection function.
It will be appreciated that in the case of vibration detection, the first output 201 and the second output 202 are also used as inputs, i.e. for inputting a first voltage to the control assembly 20.
It should be noted that, the buzzer 10 provided in the embodiment of the present application has the following two characteristics:
(1) The buzzer can generate vibration based on the driving voltage, so that vibration sounding is realized.
(2) In the case of vibration, the buzzer may follow the vibration and may generate a corresponding first voltage according to the intensity of the vibration.
It should be appreciated that the intensity of vibration is related to the magnitude of the amplitude and also to the magnitude of the frequency of vibration. The magnitude of the first voltage is related to the magnitude of the amplitude, and the frequency of the first voltage is related to the magnitude of the vibration frequency. For example, when the amplitude is larger, the amplitude of the first voltage and the vibration intensity are larger; the smaller the amplitude, the smaller the amplitude of the first voltage and the vibration intensity. For another example, when the vibration frequency is larger, the frequency and the vibration intensity of the first voltage are larger; when the vibration frequency is smaller, the frequency and the vibration intensity of the first voltage are smaller. Thus, the intensity of the vibration of the buzzer 10 may be characterized by the first voltage, for example by the amplitude and/or frequency of the first voltage.
In the above sound generating device, the same buzzer 10 can be used for generating sound and detecting vibration intensity, and can enrich functions of the electronic device, so that the electronic device has sound generating function and vibration intensity detecting function.
In some embodiments, the buzzer 10 meeting both of the above characteristics includes, but is not limited to, a piezoelectric buzzer.
In some embodiments, when the buzzer 10 is a piezoelectric passive buzzer, the driving voltage is an ac voltage, for example, the ac voltage is a square wave signal voltage. The piezoelectric passive buzzer is driven to vibrate through square wave signal voltage, so that sounding is realized.
In some embodiments, the control assembly 20 is configured to output the driving voltage in a case where it is determined that the vibration intensity of the buzzer 10 is greater than or equal to the first threshold value.
In the sound generating device, the first threshold is set to limit that the vibration intensity is detected first, and then sound generation is performed under the condition that the vibration intensity is greater than or equal to the first threshold.
In some embodiments, the alarm includes the sound emitting device. The alarm continuously detects the vibration intensity through the buzzer 10 of the sounding device, and when the vibration intensity is greater than or equal to a first threshold value, the alarm controls the buzzer 10 to sound through the control component 20 of the sounding device to give an alarm.
In the alarm, the same buzzer 10 can be used for detecting the vibration intensity and sounding the alarm, so that the hardware cost of the alarm can be saved.
In some embodiments, the sound emitting device may be applied to an anti-theft scene. For example, the sound generating device is arranged in the burglary-resisting door, the burglary-resisting window or the burglary-resisting lock. The buzzer 10 of the sound generating device continuously detects the intensity of vibration. When the vibration intensity is greater than or equal to the first threshold value, the condition indicates that the burglary-resisting door, the burglary-resisting window or the burglary-resisting lock can have larger impact, namely the burglary-resisting door, the burglary-resisting window or the burglary-resisting lock can be damaged. At this time, the control component 20 of the sounding device controls the buzzer 10 to sound and alarm, thereby realizing the anti-theft function.
In some embodiments, the control assembly 20 is configured to output a drive voltage for a preset period of time.
In the above sound generating device, in order to reasonably utilize the sound generating function of the buzzer 10, the duration of each sound generation of the buzzer 10 may be controlled by outputting a driving voltage for a preset duration.
In some embodiments, the control component 20 is further configured to stop outputting the driving voltage upon receiving a preset control command.
In the above sound generating device, in order to reasonably utilize the sound generating function of the buzzer 10, the output of the driving voltage may be stopped by a preset control command, so as to control the duration of each sound generation of the buzzer 10.
In some embodiments, as shown in fig. 2, the sound generating apparatus further includes a communication module 30, and the control assembly 20 receives a preset control instruction from the terminal device through the communication module 30.
The terminal device and the communication module 30 have a communication link relationship, and can send a preset control instruction to the communication module 30. The control component 20 is connected to the communication module 30, and receives a preset control instruction from the terminal device through the communication module 30.
Terminal devices include, but are not limited to, cell phone terminals, tablet computers, wearable devices, and the like. The communication module 30 includes, but is not limited to, a Bluetooth module, a Wi-Fi module, a ZigBee module, and the like.
In the above sound emitting device, the communication module 30 receives the preset control command from the terminal device, so as to stop outputting the driving voltage according to the preset control command, so as to control the duration of each sound emission of the buzzer 10.
In some embodiments, as shown in fig. 3, the sound generating device further includes a filter circuit 40, and the first output terminal 201 and the second output terminal 202 are connected to the buzzer 10 through the filter circuit 40.
In the above sound generating device, the control component 20 is connected to the buzzer 10 through the filter circuit 40, so as to improve the stability of the output of the driving voltage and the accuracy of the first voltage detection.
In some embodiments, as shown in fig. 4, the filter circuit 40 includes a first resistor circuit 41, a second resistor circuit 42, a third resistor circuit 43, and a first capacitor circuit 44.
The first resistor circuit 41 has a first end connected to the first output terminal 201 and a second end connected to the first terminal of the buzzer 10. The first end of the second resistor circuit 42 is connected to the second output 202, and the second end is connected to the second terminal of the buzzer 10. Both ends of the third resistor circuit 43 are connected to the first terminal and the second terminal of the buzzer 10, respectively. The first capacitor circuit 44 has both ends connected to a first terminal and a second terminal of the buzzer 10, respectively.
The first, second and third resistor circuits 41, 42 and 43 each include at least one resistor, and a plurality of resistors in each circuit are connected in series and/or in parallel. The first capacitance circuit 44 includes at least one capacitance, a plurality of capacitances being connected in series and/or in parallel therebetween.
In the above sound generating apparatus, the stability of the driving voltage output and the accuracy of the first voltage detection can be improved by the filter network composed of the first resistor circuit 41, the second resistor circuit 42, the third resistor circuit 43 and the first capacitor circuit 44.
In some embodiments, as shown in fig. 5, the functions of the control assembly 20 may be implemented by an MCU (Micro Control Unit, micro-control unit). The first Output 201 and the second Output 202 are each one IO (Input/Output) port of the MCU. For example, the first output 201 is a first port IO1 of the MCU, and the second output 202 is a second port IO2 of the MCU. The first resistor circuit 41 includes a resistor R1, the second resistor circuit 42 includes a resistor R2, the third resistor circuit 43 includes a resistor R3, and the first capacitor circuit 44 includes a capacitor C1.
The first end of the resistor R1 is connected with the first port IO1, and the second end is connected with the first end of the capacitor C1, the first end of the resistor R3 and the first wiring terminal of the buzzer 10. The first end of the resistor R2 is connected with the second port IO2, and the second end of the resistor R3 is connected with the second end of the capacitor C1 and the second terminal of the buzzer 10.
In the above sound generating device, the filter network composed of the resistor R1, the resistor R2, the resistor R3 and the capacitor C1 is used for improving the stability of the output of the driving voltage and improving the accuracy of the detection of the first voltage. In case the buzzer 10 is used for vibration intensity detection, the MCU may control the first port IO1 and the second port IO2 to be used as input terminals. In this case, the first voltage is input to the MCU through the first port IO1 and the second port IO 2. In the case where the buzzer 10 is used for sounding, the MCU may control the first port IO1 and the second port IO2 to be used as output terminals. In this case, the MCU outputs a driving voltage through the first port IO1 and the second port IO 2.
As an example, in case the buzzer 10 is used for vibration intensity detection, the MCU may set the first port IO1 to a low level and set the second port IO2 to an AD (Analog detection) port to realize detection of the first voltage.
In some embodiments, the MCU is configured to control the first port IO1 and the second port IO2 to switch from being used as an input terminal to being used as an output terminal in a case where it is determined that the vibration intensity of the buzzer 10 is greater than or equal to the first threshold, so as to implement a switch from the vibration intensity detection function to the sounding function.
In some embodiments, as shown in fig. 6, the control assembly 20 includes a detection circuit 21 and a drive circuit 22.
The detection circuit 21 has a first detection input 211 and a second detection input 212. The drive circuit 22 has a first drive output 221 and a second drive output 222.
The first detection input 211 and the first drive output 221 are connected to the first output 201, and the second detection input 212 and the second drive output 222 are connected to the second output 202.
The detection circuit 21 is configured to detect a first voltage through the first detection input terminal 211 and the second detection input terminal 212, and determine the vibration intensity of the buzzer 10 according to the first voltage.
The driving circuit 22 is configured to output a driving voltage through a first driving output 221 and a second driving output 222.
In the above sound emitting device, the first voltage may be detected by the detection circuit 21 to determine the vibration intensity of the buzzer 10. And the driving voltage can be output through the driving circuit 22 to drive the buzzer 10 to sound.
In some embodiments, as shown in fig. 7, the control assembly 20 further includes a control circuit 23 coupled to the detection circuit 21 and the drive circuit 22.
The control circuit 23 is configured to control the drive circuit 22 to output the drive voltage in the case where it is determined that the vibration intensity of the buzzer 10 is greater than or equal to the first threshold value.
In the above sound emitting device, the detection circuit 21 detects the vibration intensity, and then the control circuit 23 controls the driving circuit 22 to output the driving voltage to drive the buzzer 10 to emit sound when the vibration intensity is greater than or equal to the first threshold value.
In some embodiments, the control circuit 23 is further configured to control the first driving output 221 and the second driving output 222 of the driving circuit 22 to be in a high-impedance state and to release the high-impedance state of the first detection input 211 and the second detection input 212 of the detection circuit 21 in case the detection circuit 21 does not detect the first voltage. The control circuit 23 is further configured to control the first detection input 211 and the second detection input 212 of the detection circuit 21 to be in a high-impedance state and to release the high-impedance state of the first driving output 221 and the second driving output 222 of the driving circuit 22 when the detection circuit 21 detects the first voltage.
For example, in the case where the detection circuit 21 does not detect the first voltage, it indicates that no vibration is detected. In this case, the first and second driving output terminals 221 and 222 of the driving circuit 22 are controlled to be in a high-resistance state, and the high-resistance states of the first and second detection input terminals 211 and 212 of the detection circuit 21 are released, so that the buzzer 10 is in a vibration intensity detection state.
For another example, when the detection circuit 21 detects the first voltage, it indicates that the vibration is detected. In this case, the first detection input 211 and the second detection input 212 of the control detection circuit 21 are in a high-impedance state, and the high-impedance state of the first driving output 221 and the second driving output 222 of the driving circuit 22 is released, so that the buzzer 10 is in a sounding state.
In the above sound generating device, the conversion from the vibration intensity detection function to the sound generating function is achieved by controlling the high resistance states of the first detection input terminal 211 and the second detection input terminal 212 of the detection circuit 21 and the high resistance states of the first driving output terminal 221 and the second driving output terminal 222 of the driving circuit 22.
