the processor 10 is configured to determine a corresponding note according to a distance between the target and the electronic organ;
the voice playing unit 30 is used for playing the corresponding musical notes;
the processor 10 is further configured to select an online playing mode if the wireless transmission unit 20 is in a connected state with the mobile terminal; if the wireless transmission unit 20 is disconnected from the mobile terminal, the stand-alone play mode is selected.
Wherein the target comprises a human hand or other objects used for commanding the electronic organ to play; the mobile terminal comprises a mobile phone, a computer and the like; the online playing mode at least comprises a mobile terminal playing mode, and the stand-alone playing mode comprises an electronic organ playing mode. The voice playing unit 30 is also used for storing musical notes required by the air electronic organ.
In this embodiment, if an application scenario that a user plays, other users listen in a room, or a requirement that the user requires high tone quality is involved, the user may connect a mobile phone or a computer to the air electronic organ wirelessly, and the processor 10 detects a connection state between the wireless transmission unit 20 and the mobile terminal, and then may select an online playing mode, i.e., may select a playing mode of the mobile terminal, and a note played by the user may be played through the mobile terminal. Because the note playing tone quality of mobile terminals such as mobile phones and computers is obviously higher than that of air electronic organs, the requirement of users for higher tone quality can be met, and the user experience is favorably improved. If the application scene that the user needs to watch the performance near the air electronic organ is involved, the user does not need to connect the mobile terminal with the air electronic organ, and the processor 10 detects the disconnection state of the wireless transmission unit 20 and the mobile terminal, the single machine playing mode can be selected, and the electronic organ playing mode can be selected. After the playing mode is selected and the distance between the target and the electronic organ is obtained, the processor 10 calculates and processes the distance between the target and the electronic organ to obtain the musical note to be played, and then the processor 10 controls the voice playing unit 30 to play the musical note to be played or controls the wireless transmission unit 20 to upload the musical note data to the mobile terminal, and the musical note to be played is played through the mobile terminal.
Therefore, the Internet of things air electronic organ in the embodiment provides two play modes, namely an online play mode and a single-machine play mode, can meet various application scenes, and improves user experience; and the playing mode is selected according to the connection state of the wireless transmission unit 20 and the mobile terminal, the system can automatically identify and select, the user operation is not needed, and the use is more convenient and more humanized.
Alternatively, the processor 10 may be an STM32F103 chip, and the voice playing unit 30 may be a general speaker, etc.
Optionally, the distance measuring method of the spatial distance measuring unit 40 includes ultrasonic distance measuring and radar distance measuring. This can satisfy the spatial ranging requirements of the present embodiment. The spatial ranging unit 40 may be a general ultrasonic ranging sensor, such as HC-SR 01.
Optionally, the online playing mode includes two modes, namely mobile terminal playing and electronic organ playing.
Generally, if the requirements of multiple scenes and high sound quality of a user are to be met, in principle, only one mode of mobile terminal playing is needed to be included in the online playing mode, namely, some scenes are played by using the mobile terminal, and other scenes are played by using the electronic organ. In this embodiment, the user sometimes does not have a requirement for playing notes through the mobile terminal, but wants to play notes through the electronic organ, and further needs the mobile terminal to issue data to change the distance between the target and the electronic organ and the corresponding relationship between the notes, and at this time, the wireless transmission unit 20 of the internet of things air electronic organ needs to be kept in a connection state with the mobile terminal. If the online playing mode only comprises a mode of playing by the mobile terminal, the user also needs to disconnect the connection between the electronic organ and the mobile terminal and switch to the stand-alone playing mode, which causes inconvenience for the user.
Therefore, the online playing mode of the embodiment comprises two modes of mobile terminal playing and electronic organ playing, a user can complete two purposes of changing the distance and the corresponding relation of the musical notes and selecting the playing mode of the electronic organ at one time in the online playing mode, mode switching is not needed, and the online playing mode is more convenient to use.
The wireless transmission unit 20 is further configured to upload distance and/or note data between the target and the electronic organ if the wireless transmission unit 20 is in a connection state with the mobile terminal. Therefore, the user can timely and conveniently observe various parameters of the electronic organ through the mobile terminal.
Optionally, as shown in fig. 2, the determining, by the processor 10, a corresponding note according to a distance between the target and the electronic organ includes:
step S1, setting a plurality of distance intervals and the one-to-one corresponding relation between each distance interval and each note;
step S2, obtaining the distance between the target and the electronic organ;
step S3, judging a distance interval where the distance between the target and the electronic organ is;
and step S4, determining the musical notes corresponding to the distance interval where the distance between the target and the electronic organ is located according to the corresponding relation.
Here, how the distance between the object and the electronic organ corresponds to the note will be described. Assuming that the application distance of the electronic organ in this embodiment is 10-200CM, 10-15CM may be selected as a distance interval, 15-20CM may be selected as a distance interval, and so on. The notes include 1/2/3/4/5/6/7, such that a distance interval of 10-15CM is set for note 1, a distance interval of 15-20CM is set for note 2, and so on. If the measured distance between the target and the electronic organ is 17CM, the distance interval corresponding to the distance between the target and the electronic organ can be determined to be 15-20CM, the corresponding note is 2, and the electronic organ emits the sound of note 2. For example, the user may change the corresponding relationship between the distance between the target and the electronic organ and the musical note according to the user's needs, for example, 15-17CM is set as a distance interval, and the distance interval of 15-17CM is set to correspond to the musical note 1.
Thus, through the steps, the corresponding note can be determined according to the distance between the target and the electronic organ, the corresponding relation between the distance between the target and the electronic organ and the note can be freely changed, the degree of freedom of the user is higher, and the participation sense is stronger.
Optionally, the farther the distance between the target and the electronic organ is, the longer the distance interval in which the distance between the target and the electronic organ is located.
In general ranging techniques, such as ultrasonic ranging and radar ranging mentioned in this embodiment, the farther the distance is, the greater the error of the ranging, and thus the lower the accuracy of playing notes. If 10-15CM is set to correspond to one note, 15-20CM is set to correspond to one note, and 20-25CM is set to correspond to one note, that is, the length of the distance interval where the distance between the target and the electronic organ is 5CM, the note may be inaccurate.
Such as: setting a distance interval of 10-15CM for a note 1, setting a distance interval of 15-20CM for a note 2, setting a distance interval of 25-30CM for a note 4, setting a distance interval of 30-35CM for a note 5, and setting a distance interval of 35-40CM for a note 6. When the distance between the target and the electronic organ is 30CM, the note 5 is correctly played, and when the distance between the target and the electronic organ is 35CM, the actually corresponding note is still 5, and the measured distance is 36CM possibly due to the distance measurement error, and the played note is changed to 6. Thus, the original notes played twice should be 5, but the measurement error causes the inaccurate playing of the notes for the second time.
In this embodiment, the distance interval 10-15CM may be set for the note 1, the distance interval 15-21CM may be set for the note 2, the distance interval 21-28CM may be set for the note 3, the distance interval 28-36CM may be set for the note 4, and the longer the distance between the target and the electronic organ, the longer the distance interval between the target and the electronic organ is. When the distance between the target and the electronic organ is 30CM, the note 4 is played, and when the distance between the target and the electronic organ is 35CM, even if the measured distance is 36CM due to the ranging error, the distance interval where 36CM is located is still 28-36CM, and the corresponding note is still 4. Therefore, the notes played twice originally are all 4, the notes played twice actually are all 4, and the played notes are accurate.
Therefore, in the embodiment, the farther the distance between the target and the electronic organ is, the longer the distance interval between the target and the electronic organ is, so that the condition that the musical notes are inaccurate due to the distance measurement error can be compensated, and the performance of the air electronic organ is better.
Optionally, as shown in fig. 1, the internet of things air electronic organ further includes a temperature and humidity sensor 50, the temperature and humidity sensor 50 is electrically connected to the processor 10, and the processor 10 is further configured to perform compensation operation on the distance according to the ambient temperature and humidity.
Because the speed of the ultrasonic wave is irregularly changed due to the change of the ambient temperature and humidity, if the measured data is not corrected, a distance measurement error can be caused, and the performance of the electronic organ is further influenced.
Like this, the electronic organ in this embodiment still includes temperature and humidity sensor 50, and processor 10 still is used for right according to the environment humiture the distance carries out compensation operation, reduces the influence of environment humiture to distance measurement, and the accuracy of broadcast musical note is higher, is favorable to guaranteeing the good performance of electronic organ.
Optionally, the temperature and humidity sensor is 50SHT 11.
Optionally, as shown in fig. 1, the internet of things air electronic organ further includes a display screen 60, and the display screen 60 is electrically connected to the processor 10 and is configured to display the distance and/or the note data. The display screen 60 may also be used to display battery power.
Optionally, the wireless transmission unit 20 includes WiFi or bluetooth. Therefore, the wireless connection requirement of the electronic organ and the mobile terminal can be met.
Optionally, the spatial distance measuring unit 40 is configured to measure a distance between a target located right in front of the spatial distance measuring unit and the electronic organ.
Generally, in other application fields, the radiation range of the device for spatial ranging is large, and a specific target identification function is arranged between the ranging device and the target, so that the ranging can be performed as long as the target is within the radiation range of the ranging device. However, the conventional distance measuring device has the advantages of identification function, large radiation range and the like, so that the cost is inevitably high.
On the other hand, if the radiation range of the distance measuring device is considered to be large but the identification function for a specific target is not required, since a plurality of objects may exist in the measurement range of the spatial distance measuring unit 40, the user may be disturbed to direct the performance of the electronic organ, and the large radiation range of the distance measuring device may increase the cost of the electronic organ.
On the other hand, if the function of identifying a specific target is considered but the radiation range of the distance measuring device is not required to be large, the function of identifying a specific target also increases the cost of the electronic organ.
In summary, for the function with a large range of ranging radiation and the identification function for a specific target, no matter how the function is chosen, the purposes of low cost and interference avoidance cannot be achieved at the same time. Thus, the present embodiment preferably targets the space-measuring unit 40 directly in front, i.e. the space-measuring unit 40 is set to measure only the distance between the object directly in front and the electronic organ. Because the space distance measuring unit 40 can only measure the distance between an object in front and the electronic organ, on one hand, the space distance measuring unit 40 can only accommodate one target in front, the identification function aiming at a specific target is replaced, the interference of other objects on the electronic organ performance instructed by the user is avoided, the space distance measuring unit 40 does not need to have the identification function aiming at the specific target, namely, the cost is reduced on the premise that the space distance measuring unit 40 avoids the interference of other objects on the electronic organ performance instructed by the user; on the other hand, the spatial distance measuring unit 40 in the present embodiment does not have the function of a large radiation range, so that the cost of the electronic organ can be further reduced. Although the inter-range unit 40 does not have a function of a large radiation range, which may occasionally cause inconvenience to a user, its low cost characteristic is very suitable for a simple toy such as an electronic organ.
In this way, in the embodiment, the target is preferably located right in front of the spatial distance measuring unit 40, so that interference of other objects on the performance of the electronic organ commanded by the user can be avoided without having a function of identifying a specific target, and the cost is greatly reduced on the premise of ensuring that the distance measuring function can be realized.
Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
