Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a bluetooth pairing method for a music device according to a first embodiment of the present invention includes:
step S100, when a pairing request of a terminal is received, acquiring a pairing password composed of numbers.
Specifically, when the music device receives a pairing request from a terminal, a pairing password composed of numbers is generated, the terminal may be a desktop device such as a computer, a mobile phone, a PAD, or other music devices, and the pairing password may be a dynamically generated random number group or a fixed number group preset and stored in the music device. In order to expand the Bluetooth function of the music equipment, particularly the function of password setting or obtaining, the music equipment is externally connected with a control device through a USB interface of the music equipment, and a dynamically generated pairing password can be displayed or a fixed digital group can be set through the external control device.
Step S200, when a note sent by the music equipment is detected, acquiring an input number corresponding to the note according to a mapping relation between the note and the number established in advance, and comparing the input number with the pairing password;
and step S300, when the input number is consistent with the pairing password, setting the pairing request to pass through so as to carry out communication between the terminal and the music equipment.
Specifically, because a digital password is used in the bluetooth pairing process, and a note can only be input if a number cannot be input by using the music equipment, a mapping relationship between the note and the number is established in advance, and the note is corresponding to the numbers 0-9, so that the password is formed and used in the authentication/pairing process.
In the conventional MIDI standard, the corresponding relationship between the note and the MIDI pitch is shown in the following table:
| musical notes | MIDI pitch (decimal representation) |
| C3 | 48 |
| C#3 | 49 |
| D3 | 50 |
| D#3 | 51 |
| E3 | 52 |
| F3 | 53 |
| F#3 | 54 |
| G3 | 55 |
| G#3 | 56 |
| A3 | 57 |
| A#3 | 58 |
| B3 | 59 |
For example, in the case of a MIDI keyboard, starting with the note name C3 (i.e., MIDI pitch 48), the MIDI pitch is mapped to a number to indirectly establish the mapping relationship between the note and the number, for example,
MIDI pitch "48", mapped to the number "1",
MIDI pitch "50", mapped to the number "2",
MIDI pitch "52", mapped to the number "3",
MIDI pitch "53", mapped to the number "4",
MIDI pitch "55", mapped to the number "5",
MIDI pitch "57", mapped to the number "6",
MIDI pitch "59", mapped to the number "7",
MIDI pitch "54", mapped to the number "8",
MIDI pitch "56", mapped to the number "9",
MIDI pitch "58", mapped to the number "0",
MIDI pitch "49", mapped to the delete key "Del",
the MIDI pitch "51" is mapped to the Enter key.
Taking a MIDI drum as an example, since a MIDI drum set has more than forty kinds of drum sounds, and users generally use about ten drum sounds, the MIDI drum is complicated to use, and users need to allocate MIDI pitches of drum sounds to 48 to 59 ranges in advance according to their MIDI drum apparatuses.
Starting with the note name C3 (i.e., MIDI pitch 48), the MIDI pitch is mapped to a number, e.g.,
MIDI pitch "48", mapped to the number "1",
MIDI pitch "50", mapped to the number "2",
MIDI pitch "52", mapped to the number "3",
MIDI pitch "53", mapped to the number "4",
MIDI pitch "55", mapped to the number "5",
MIDI pitch "57", mapped to the number "6",
MIDI pitch "59", mapped to the number "7",
MIDI pitch "54", mapped to the number "8",
MIDI pitch "56", mapped to the number "9",
MIDI pitch "58", mapped to the number "0",
MIDI pitch "49", mapped to the delete key "Del",
the MIDI pitch "51" is mapped to the Enter key.
When a pairing request of a terminal is received, a user inputs corresponding notes into MIDI music equipment according to the acquired pairing password and the mapping relation between the notes and the numbers, and once the number group obtained by analyzing the notes is successfully matched with the pairing password, Bluetooth connection can be achieved.
There are many kinds of music devices, such as MIDI keyboards, MIDI pads, MIDI guitars, etc., but these music devices can all obtain the same musical notes, so that the pairing process in the bluetooth connection between various MIDI music devices and external devices can be realized only by setting a mapping relation comparison table between a set of musical notes and numbers.
In the technical scheme provided by the invention, the characteristic that MIDI music equipment has note information is utilized, and the mapping relation between notes and numbers is pre-established. When a MIDI music apparatus receives a pairing request from a terminal, a pairing password composed of a set of numbers is generated. When the number corresponding to the note sent by the user operating the MIDI music equipment is consistent with the pairing password, the pairing is successful, and therefore the communication between the terminal and the music equipment is realized. Because the password is not public, the use hidden danger and the information safety hidden danger of the music equipment can be eliminated.

Specifically, in order to enhance the security of bluetooth connection, the mapping relationship between the notes and numbers used for bluetooth connection of each MIDI music device may be set individually by the manufacturer, and therefore, after obtaining the pairing password, the user needs to query the notes corresponding to the pairing password. The mapping relation may be printed in the specification, or may be displayed on the musical apparatus or the control apparatus connected to the musical apparatus.
Further, on the basis of the first or second embodiment, the bluetooth pairing method for a music device further includes:
and presetting the pairing password and storing the pairing password in the music equipment.
Specifically, the user may preset a pairing password and store the pairing password in the music device, and once the terminal requests pairing with the music device, the user may input a note corresponding to the pairing password to implement bluetooth connection.
In addition, the Bluetooth connection mode can be further set, and after the terminal is successfully paired with the music equipment for the first time, the subsequent terminal can be directly connected with the music equipment without verifying again. Certainly, the user can also set the MIDI music apparatus to be secret-free authenticated/paired, which is suitable for the music apparatus in a safer environment.
Further, on the basis of the first or second embodiment, the pairing password is displayed on a display screen, wherein the display screen is arranged on the music device or on a control device connected with the music device or on the terminal.
Specifically, in order to facilitate the user to obtain the pairing password, the music device is externally connected with the control device to display the pairing password, and if the music device is provided with a display screen, the pairing password can be directly displayed on the music device. In addition, in consideration of the functional limitation of the music equipment terminal, the pairing password can be directly displayed on the terminal, when the terminal sends a pairing request to the music equipment, the pairing password is displayed on the terminal, and a user inputs a note corresponding to the pairing password to the music equipment according to the mapping relation between the note and the number, so that the Bluetooth connection between the terminal and the music equipment can be realized.
Of course, the mode of acquiring the pairing password can be displayed through a display screen, and can also be sent to a device such as a mobile phone in the form of a short message through the control device. If the music equipment has the wireless communication function, such as WIFI, once a Bluetooth pairing request of the terminal is received, a pairing password is sent to equipment, such as a mobile phone bound with the music equipment.

In order to expand the Bluetooth function of the music equipment, particularly the function of password setting or obtaining, the music equipment is externally connected with a control device through a USB interface of the music equipment, and a dynamically generated pairing password can be displayed or a fixed digital group can be set through the external control device.
