Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
When the water is fed into the loudspeaker, the sounding of the loudspeaker is affected, and the service life of the loudspeaker is seriously affected. Therefore, it is desirable to detect whether or not the speaker is being fed with water in real time during use of the speaker.
The present disclosure provides a loudspeaker using method, which is to detect whether the loudspeaker is in water or not in real time when the loudspeaker is used, so as to avoid damage to the loudspeaker caused by continuous use of the loudspeaker when the loudspeaker is in water. Specifically, a reference impedance value of the loudspeaker is obtained, a measured impedance value of the loudspeaker is obtained, the reference impedance value and the measured impedance value are impedance values in a frequency domain, the reference impedance value and the measured impedance value are compared, when the difference value between the measured impedance value and the reference value is larger than a set threshold value, water inflow of the loudspeaker is determined, and the loudspeaker stops working.
The method is applied to the electronic terminal equipment provided with the loudspeaker. The electronic terminal device can be a mobile phone, a PAD, a sound, a wearable device and the like.
Fig. 1 is a flowchart illustrating a speaker using method according to an exemplary embodiment, the method being applied to a terminal including a speaker, as shown in fig. 1, the method including the steps of:
102, acquiring a frequency domain measured impedance value of the loudspeaker;
and 103, when the difference value between the frequency domain measured impedance value and the frequency domain reference impedance value is larger than a set threshold value, determining that the loudspeaker has a fault and automatically interrupting the work of the loudspeaker.
Repeated experimental research shows that the frequency domain impedance value of the loudspeaker in the water inlet state is larger than that in the normal state. The larger the water inflow, the larger the deviation of the frequency domain impedance from the normal value. Therefore, the method judges whether the loudspeaker enters water or not by comparing the frequency domain impedance value measured in real time with the normal value.
In steps 101 and 102, when detecting whether the loudspeaker is flooded, it is necessary to obtain a frequency domain reference impedance value when the loudspeaker normally operates without flooding and obtain a frequency domain measured impedance value of the loudspeaker in real time. The frequency domain reference impedance value is an impedance value of the loudspeaker in normal work, and the frequency domain measured impedance value is obtained by real-time measurement and calculation of a measuring instrument in the work of the loudspeaker. It should be noted that the frequency domain reference impedance value and the frequency domain measured impedance value are both impedance values in the frequency domain, that is, impedance values in the frequency domain calculated by the frequency domain voltage across the speaker and the frequency domain current flowing through the speaker.
In step 103, after the water is fed into the loudspeaker, the frequency domain impedance of the loudspeaker during operation is greater than the frequency domain impedance of the loudspeaker during normal operation without water feeding. Therefore, it is possible to determine whether the speaker is flooded and the degree of flooding by calculating the difference between the frequency domain measured impedance value and the frequency domain reference impedance value and determining whether the difference is greater than a set threshold value. If the frequency domain measured impedance value is larger than the frequency domain reference impedance value, but the difference value of the two impedance values does not reach the set threshold value, the fact that the loudspeaker has water inflow is indicated, but the water inflow degree is light, and the loudspeaker cannot be seriously influenced by using the loudspeaker. If the difference value of the two values reaches or even exceeds the set threshold value, the water inlet of the loudspeaker is serious, the loudspeaker cannot be used continuously, and otherwise, the service life of the loudspeaker is influenced.
In the method, the working voltage and current of the loudspeaker are measured in real time to obtain a measured impedance value in a frequency domain, and then the measured impedance value in the frequency domain and a reference impedance value in the frequency domain are compared to judge whether the loudspeaker enters water or not, if the situation that the loudspeaker enters water is determined, a user is reminded to stop using the loudspeaker and/or automatically stop working of the loudspeaker, and the purpose of protecting the loudspeaker is achieved.
In an alternative embodiment, the obtaining the frequency domain reference impedance value of the loudspeaker includes:
acquiring time domain reference voltage and time domain reference current in a first set time period when the loudspeaker is in a normal working state under the condition that water does not enter the loudspeaker;
converting the time domain reference voltage and the time domain reference current into a frequency domain to obtain corresponding frequency domain reference voltage and frequency domain reference current;
calculating to obtain frequency domain reference impedance based on the frequency domain reference voltage and the frequency domain reference current;
and selecting the peak value of the frequency domain reference impedance as the reference impedance value.
Since the frequency domain reference impedance value and the frequency domain measured impedance value used for determining whether water enters are both impedance values in the frequency domain, the frequency domain reference voltage and the frequency domain reference current need to be obtained by performing time-frequency transformation, such as fourier transformation, on the time domain reference voltage and the time domain reference current in the first set time period. It should be noted that the time-domain reference voltage and the time-domain reference current obtained here, and the corresponding frequency-domain reference voltage and the frequency-domain reference current are all presented in the form of a voltage curve or a current curve. And dividing the frequency domain reference voltage by the frequency domain reference current to calculate the frequency domain reference impedance. The peak value, i.e. the maximum value, of the frequency domain reference impedance is selected as the reference impedance value.
In an alternative embodiment, the obtaining a frequency domain measured impedance value of the loudspeaker includes:
acquiring time-domain measurement voltage and time-domain measurement current of the loudspeaker within a second set time period;
converting the time domain measurement voltage and the time domain measurement current into a frequency domain to obtain corresponding frequency domain measurement voltage and frequency domain measurement current;
calculating to obtain frequency domain measurement impedance based on the frequency domain measurement voltage and the frequency domain measurement current;
and selecting the peak value of the frequency domain measured impedance as the measured impedance value.
In this embodiment, the frequency domain measured impedance value of the loudspeaker is obtained in real time by the time domain measured voltage and the time domain measured current at the present time and in a period of time before the present time. Similarly to the above manner of obtaining the reference impedance value, the obtained time-domain measurement voltage and time-domain measurement current in the second set time period are subjected to time-frequency transformation, such as fourier transformation, to obtain a frequency-domain measurement voltage and a frequency-domain measurement current. And dividing the frequency domain measurement voltage by the frequency domain measurement current to obtain the frequency domain measurement impedance. The peak value, i.e. the maximum value, of the frequency domain measured impedance is selected as the measured impedance value.
In an alternative embodiment, the method further comprises:
and sending out prompt information for indicating that the loudspeaker is in failure.
In this embodiment, determining to stop operation of the speaker may be represented by the terminal provided with the speaker sending a prompt to the user indicating that the user has entered water into the speaker and please stop using the speaker. For example, the prompt message may be displayed on a display screen of the terminal, or in the case where an indicator lamp is provided on the terminal, the indicator lamp may be blinked to indicate a malfunction of the terminal. Because the loudspeaker intakes at this moment, then no longer adopt the mode of sending the chimes of doom to indicate the user. In addition, the operation of the loudspeaker can be automatically interrupted while the prompt message is sent, for example, the power supply circuit of the loudspeaker is automatically disconnected, so that the situation that the user continues to use the loudspeaker without noticing the prompt message is prevented, and the damage to the loudspeaker is caused.
In an alternative embodiment, the set threshold value ranges from 1 ohm.
When the difference value between the measured impedance value and the reference impedance value is small, the water inlet condition of the loudspeaker is light, and the service life of the loudspeaker is not influenced by using the loudspeaker. The setting of the threshold value here is therefore very important. If the set threshold is too low, some unnecessary speakers are interrupted to be used, so that the use experience of a user is influenced; if the set threshold value is too high, the loudspeaker is still not used for alarming when the water inlet condition of the loudspeaker is serious, and the service life of the loudspeaker is influenced.
It has been found through a number of experiments that this can be avoided when the threshold is set to 1 ohm. The set threshold is set for different speaker configurations and terminal configurations.
In an optional embodiment, the first set time period ranges from 0.01 second to 1 second, and the second set time period ranges from 0.01 second to 1 second.
The value ranges of the first set time period and the second set time period are both 0.01 second to 1 second, and the first set time period and the second set time period can be the same or different. For example, the first set period of time and the second set period of time are both set to 0.1 second. Namely, the voltage and the corresponding current within 0.1 second when the loudspeaker normally works are selected to calculate the reference impedance value, and when the measured impedance of the loudspeaker is detected in real time, the voltage and the corresponding current within the current time and 0.1 second before the current time are selected to calculate the measured impedance value. And setting the value ranges of the first set time period and the second set time period according to the speaker configuration, the terminal configuration and the practical application scene.
Specific embodiments according to the present disclosure are described below in conjunction with specific application scenarios. In this embodiment, the speaker using method includes the steps of:
208, selecting a frequency domain to measure the impedance Rf2The peak value of (a) is taken as the measured impedance value.
Step 209 calculates the difference between the measured impedance value and the reference impedance value.
