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.
In order to prevent damage to the speaker due to an excessively low temperature during use of the speaker, the use temperature of the speaker is generally controlled. When it is detected that the ambient temperature of the speaker is too low, the output of the speaker is reduced or stopped. At present, low-temperature protection for the loudspeaker is carried out by detecting the ambient temperature (detecting the actual chip temperature), and the temperature of the loudspeaker can rise after the loudspeaker works for a period of time, so that the local temperature of the loudspeaker body can reach the normal working temperature. However, the chip temperature does not rise as fast as the speaker body temperature, and therefore the state of the speaker cannot be obtained in real time using the method of chip temperature detection, thereby affecting the actual speaker output.
The disclosure provides a method for playing audio by a loudspeaker, in the method, after a loudspeaker playing instruction is received, a parameter related to the coil temperature of the loudspeaker is obtained, the coil temperature of the loudspeaker is judged to be lower than a set temperature according to the parameter, if the coil temperature is lower than the set temperature, a set sound source is played, and the frequency of the set sound source is greater than the set frequency. And in the process of acquiring parameters related to the coil temperature of the loudspeaker, if the coil temperature of the loudspeaker is increased to a set temperature or the set sound source is played for a set time, the set sound source is stopped playing. And after the set sound source is stopped being played, playing corresponding audio based on the playing instruction. By adopting the method, when the temperature of the loudspeaker is too low, the loudspeaker coil is preheated by playing a sound source which has no damage to the loudspeaker through the loudspeaker. When the temperature of the loudspeaker coil reaches the temperature threshold, the specified audio is played. The loudspeaker can be used in a low-temperature environment, cannot be damaged, and the service life of the loudspeaker is prolonged.
The speaker may be a speaker provided in the smart terminal, such as a mobile phone, a PAD, a wearable device, or the like, or may be a speaker provided in another electronic device.
Fig. 1 is a flow chart illustrating a method for playing audio with a speaker, as shown in fig. 1, according to an exemplary embodiment, the method comprising the steps of:
and 104, playing corresponding audio based on the playing instruction.
Here, a speaker provided in a mobile phone is taken as an example, and a speaker provided in another electronic device operates in the same manner.
In step 101, for example, when a user wants to play audio, a play instruction is issued to the mobile phone. When the loudspeaker receives the playing instruction, whether the loudspeaker is in a low-temperature environment which is harmful to the playing audio is judged, namely whether the coil temperature is set or not is judged. When judging whether the coil temperature meets the set requirement, the judgment can be carried out through parameters related to the coil temperature. The parameter related to the coil temperature may be a coil temperature value, a coil resistance value.
Here, unlike the method of detecting the ambient temperature using the speaker in the related art, a method of detecting the temperature of the coil of the speaker is adopted. Therefore, the temperature condition of the loudspeaker can be accurately acquired, and the problem that the loudspeaker cannot be normally used due to too low ambient temperature when the temperature of the loudspeaker reaches the requirement of normal playing is avoided.
In step 102, when the coil of the speaker is determined to be lower than the set temperature according to the parameters, that is, when the temperature of the coil of the speaker is determined to be too low, the coil of the speaker needs to be preheated first to raise the temperature of the coil of the speaker. Here, preheating the speaker coil is achieved by playing the set sound source. Here, when the speaker is warmed up by playing the set sound source, the speaker is required to play the set sound source in a low-temperature environment without damaging the speaker.
Through a large number of experiments, it is found that when the signal frequency of the set sound source is greater than the set frequency, the requirement that the loudspeaker is not damaged when the sound source is played in a low-temperature environment can be met. The set frequency here may be 2 KHz. Specifically, the specific numerical value of the set frequency may be set based on different speaker models, the conditions of the speaker itself, and the conditions of the hardware system.
In addition, the set temperature may be set to-10 ℃ to-20 ℃. In particular, the implementation can be set according to the parameters of the loudspeaker and the requirements of the system.
In step 103, in the process of acquiring the parameter related to the coil temperature, if it is determined that the coil temperature of the speaker is raised to the set temperature or the set sound source is played for the set time based on the parameter, the preheating of the speaker is stopped, that is, the set sound source is stopped from being played. The reason that the set sound source is played for the set time length is to prevent the user from waiting for a long time due to the overlong preheating time so as to improve the use experience of the user.
In step 104, when it is determined that the temperature of the speaker itself meets the requirement, the audio specified in the received playing instruction can be played.
By adopting the method, when the temperature of the loudspeaker is too low, the loudspeaker coil is preheated by playing a sound source which has no damage to the loudspeaker through the loudspeaker. When the temperature of the loudspeaker coil reaches the temperature threshold, the specified audio is played. The loudspeaker can be used in a low-temperature environment, cannot be damaged, and the service life of the loudspeaker is prolonged.
In an alternative embodiment, the parameter related to the coil temperature of the speaker is a coil resistance value or a coil temperature value of the speaker.
Here, whether the coil temperature meets the requirement is determined by the coil resistance value because the coil resistance value of the speaker and the coil temperature value satisfy a certain functional relationship. Therefore, when determining whether the coil temperature meets the requirement, the relationship between the coil temperature value and the set temperature can be determined by judging the relationship between the coil resistance value and the resistance threshold value through the functional relationship between the coil resistance value and the coil temperature value instead of obtaining the final coil temperature value.
The functional relationship between the resistance value of the coil and the temperature value of the coil can be known by those skilled in the art through the knowledge of the relevant technology, and will not be described herein. In addition, the manner of obtaining the resistance value of the coil can also be known by those skilled in the art through the related technical knowledge, and therefore, the description thereof is omitted.
In an alternative embodiment, when the parameter is the coil temperature value, the obtaining the parameter related to the coil temperature of the speaker includes:
acquiring a coil resistance value of the loudspeaker;
determining the coil temperature value based on the coil resistance value.
Based on the above description, when the parameter related to the coil temperature is the coil temperature value, the coil resistance value of the speaker may be obtained in real time, and the coil temperature value may be calculated according to a functional relationship between the coil resistance value and the coil temperature value.
Two parameter selection methods are given here: after the resistance value of the coil is obtained, the relationship between the resistance value and the set resistance is directly judged; or after the resistance value of the coil is obtained, the temperature value is calculated based on the resistance value, and then the relation between the temperature value and the set temperature is judged. It should be noted that both parameter selection methods can be used, and they are also consistent in nature.
In an alternative embodiment, the set sound source is an audio signal including one frequency or an audio signal including a plurality of frequencies.
In the present disclosure, the selection of the set sound source is very important because the speaker cannot be damaged by the requirement of playing the set sound source in a low temperature environment. It has been found through a number of experiments that when setting the sound source to meet the frequency requirement, it is possible to set the sound source to include either one frequency or a plurality of frequencies. The set sound source may be generated by a high-frequency signal, or may be generated by filtering a signal to remove a low-frequency component that does not meet the frequency requirement.
In an alternative embodiment, the set sound source is an ultrasonic signal.
The setting sound source may be an ultrasonic signal. As known to those skilled in the art, when playing an ultrasound signal, software and hardware support of the handset system is required.
In addition, for high-frequency signals (signals with the frequency of more than 2 KHz), the amplitude is small, so when the loudspeaker plays the set sound source, the played sound volume is low, and the user is not greatly influenced.
It should be noted that, after receiving the speaker playing instruction, if it is determined that the parameter related to the coil temperature of the speaker is greater than or equal to the corresponding parameter threshold, the related audio is played directly based on the playing instruction without executing the preheating process.
Specific embodiments according to the present disclosure are described below in conjunction with specific application scenarios. In this embodiment, the speaker is disposed on the PAD and the user plays audio through an application on the PAD. Wherein, the temperature threshold is set to be-15 ℃, and the set frequency is set to be 2 KHz. As shown in fig. 2, the method in this embodiment comprises the steps of:
And 203, obtaining a coil temperature value of the loudspeaker based on the functional relation between the resistance value and the temperature value.
And 204, judging whether the temperature value of the coil is less than-15 ℃.
And step 205, if the frequency is smaller than the preset frequency, playing a set sound source with the frequency of 3000KHz to preheat the loudspeaker.
And step 206, in the process of playing the set sound source, acquiring the resistance value of the coil in real time and obtaining a corresponding temperature value of the coil.
And step 207, stopping playing the set sound source if the coil temperature value acquired in real time is judged to be greater than or equal to-15 ℃.
And step 208, playing the audio in the speaker playing instruction.
By adopting the method in the embodiment, the temperature value of the coil is monitored in real time, and when the temperature value is lower, the coil is preheated. And once the coil is preheated to the temperature value to meet the normal playing requirement, stopping preheating the coil and playing the audio in the playing instruction of the user. The method is simple and convenient to operate and easy to realize, does not need to additionally increase devices, simultaneously achieves the purpose of protecting the loudspeaker, and prolongs the service life of the loudspeaker and related equipment.
The present disclosure also provides an apparatus for playing audio by using a speaker, as shown in fig. 3, the apparatus including:
a receiving module 301 configured to receive a play instruction;
an obtaining module 302 configured to obtain a parameter related to a coil temperature of the speaker after receiving a play instruction;
a playing module 303 configured to play a set sound source when it is determined that the coil temperature is lower than a set temperature, wherein a signal frequency of the set sound source is higher than a set frequency; when the temperature of the coil is increased to a set temperature or the set sound source is played for a set time, the set sound source is stopped to be played; and after the set sound source is stopped being played, playing the corresponding audio based on the playing instruction.
In an alternative embodiment, the parameter related to the coil temperature of the speaker is a coil resistance value or a coil temperature value of the speaker.
In an alternative embodiment, the obtaining module 302 is further configured to:
acquiring a coil resistance value of the loudspeaker;
determining the coil temperature value based on the coil resistance value.
In an alternative embodiment, the set sound source is an audio signal including one frequency or an audio signal including a plurality of frequencies.
In an alternative embodiment, the set sound source is an ultrasonic signal.
With regard to the apparatus in the above-described embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be elaborated here.
By adopting the method disclosed by the disclosure, after a loudspeaker playing instruction is received, the parameter related to the coil temperature of the loudspeaker is obtained, the coil temperature of the loudspeaker is judged to be lower than the set temperature according to the parameter, if the coil temperature of the loudspeaker is lower than the set temperature, the set sound source is played, and the frequency of the set sound source is higher than the set frequency. And in the process of acquiring parameters related to the coil temperature of the loudspeaker, if the coil temperature of the loudspeaker is increased to a set temperature or the set sound source is played for a set time, the set sound source is stopped playing. And after the set sound source is stopped being played, playing corresponding audio based on the playing instruction. By adopting the method, when the temperature of the loudspeaker is too low, the loudspeaker coil is preheated by playing a sound source which has no damage to the loudspeaker through the loudspeaker. When the temperature of the loudspeaker coil reaches the temperature threshold, the specified audio is played. The loudspeaker can be used in a low-temperature environment, cannot be damaged, and the service life of the loudspeaker is prolonged.
In addition, the method can accurately acquire the temperature condition of the loudspeaker, and avoid the problem that the temperature of the loudspeaker reaches the requirement of normal playing, but the loudspeaker cannot be normally used due to too low ambient temperature.
