[0060] cooperate with Figure 3 As shown in the figure, the sound - generating component 3 mainly includes a controller 31 and a speaker unit. The controller 31 is electrically connected to the keyboard controller 13 of the computer keyboard 1. The speaker unit mainly consists of a variety of magnetic elements (such as Figure 3 the first magnetic element 32 and the second magnetic element 33 shown in the figure) and a diaphragm 34 for generating sound. One of the first magnetic element 32 and the second magnetic element 33 can use a traditional coil or a micro - coil element 30. After passing an electric current, a magnetic field is formed on the coil, which can interact with other magnetic - conductive elements or another magnetic element (such as a magnet or other elements that can induce a magnetic field) in the sound - generating component 3, and by changing the direction of the electric current, a magnetic field with a changeable polarity can be formed, which can drive the diaphragm 34 in the sound - generating component 3 to vibrate at a specific frequency, and generate sound by pushing air.

[0061] cooperate with Figure 3 As shown in the figure, the sound - generating component 3 may also include other circuit elements for processing sound signals, such as an amplifier 35 and an equalizer 36 electrically connected to the controller 31.

Among them, the upper suspension edge 38 is also used to support the diaphragm 34 that does not directly contact the housing, that is, the diaphragm 34 is connected to the sound generating component housing 37 through the upper suspension edge 38. The first magnetic element 32 can be composed of a microcoil element 30, and the polarity can be changed and a magnetic field can be formed by energization; while the second magnetic element 33 can adopt a magnetic element with a fixed polarity. Through the interaction between the first magnetic element 32 and the second magnetic element 33, the first magnetic element 32 drives the diaphragm 34 to move with the force generated by the changing magnetic field, thereby generating sound waves flowing in the sound generating component 3 and emitting sound through the air holes 371.

[0064] The microcoil element 30 can be an element (such as a chip) made by plating, metallization or etching, and is electrically connected to its control circuit by wire bonding, flip chip, flexible printed circuit (FPC), or direct connection by wire leads. All the magnetic elements in the above-mentioned sound generating component 3 can adopt this kind of microcoil element 30, or an array-type microcoil element 30 formed by multiple microcoil elements 30; it can also be that one of the two magnetic elements adopts it, and the other is a specific magnetic object (such as a magnet).

The starting point can be set at any position of the microcoil element 30, preferably at a position close to the central area of the microcoil element 30, but it is not limited thereto, and the position of the starting point can be determined according to actual requirements. The starting point forms a first electrode 302, for example, the negative electrode of the microcoil element 30, and the end of the metal line segment 301, that is, the end of the multiple continuous wiring metal line segments 301, is the second electrode 303 of the microcoil element 30, which can be the positive electrode of the microcoil element 30. Each of the metal line segments 301 has two ends, one of which is the end of the first electrode 302, such as the end closer to the first electrode 302 formed at the starting point; the other end is the end of the second electrode 303, which is the end closer to the end of the metal line segment 301, that is, the second electrode 303.

[0067] Cooperate with Figure 8 As shown, the microcoil element 30 also has a negative electrode collecting layer 305 that collects the first electrode 302 ends (such as negative electrodes) of the respective metal line segments 301 on the wiring layer. The negative electrode collecting layer 305 has a first electrode region 3051 that collects the first electrode 302 ends of the respective metal line segments 301. The first electrode region 3051 uses an electrical pad (pad), and the first electrode region 3051 needs to have sufficient area to connect multiple first metal lines 306 (corresponding to connecting the metal line segments 301 on the wiring layer mentioned above). The first metal lines 306 in this negative electrode collecting layer 305 are used to guide the connection of the negative electrodes of the respective metal line segments 301 in the wiring layer.

[0068] Cooperate with Figure 9 As shown, the microcoil element 30 also has a positive electrode collecting layer 307 that collects the second electrode 303 ends (such as positive electrodes) of the respective metal line segments 301 on the wiring layer. The positive electrode collecting layer 307 has a second electrode region 3071 that collects the second electrode 303 ends of the respective metal line segments 301. The second electrode region 3071 uses an electrical pad (pad), and the second electrode region 3071 needs to have sufficient area to connect multiple second metal lines 308 (corresponding to connecting the metal line segments 301 on the wiring layer mentioned above). The second metal lines 308 in this positive electrode collecting layer 307 are used to guide the connection of the positive electrodes of the respective metal line segments 301 in the wiring layer.

The operating system A21 generates sound signals, performs corresponding format conversion (such as analog-to-digital conversion) and signal encoding, and then transmits them to the computer input device through specific communication technologies (such as Bluetooth communication technology, USB, etc.); after the keyboard controller 13 in the computer keyboard 1 receives the sound signals, it can perform decoding and generate a control current, which is then transmitted to the controller 31 in the sound-emitting component 3 for control. After digital-to-analog conversion by the controller 31, an analog sound signal that can be broadcast is generated and output to the speaker unit of the sound-emitting component 3, so as to control the operation of the magnetic elements of the speaker unit through the control current (including controlling the magnitude and change of the magnetic field generated by the magnetic elements), and drive the diaphragm 34 to move through the interaction between the magnetic elements to play sound (that is, play sound through the speaker unit of the sound-emitting component 3).

In a specific application, the sound receiving component 4 is started, and audio is received through one or more sound receiving components 4 in the computer keyboard 1;

[0083] Next, the relevant circuit of the sound receiving component 4 can perform preliminary processing, including analog-to-digital conversion, amplification and then noise reduction, such as eliminating keyboard noise;

[0084] After that, the processed audio is transmitted to the computer host A, and the operating system A21 run by the computer system A2 processes it according to a specific application and then forms a sound signal, which is output to the keyboard controller 13 of the computer keyboard 1 and output to each sound generating component 3 through the keyboard controller 13 to play sound.

[0085] In summary, the audible computer input device B of the present utility model can emit sound freely by providing a sound-emitting component 3 capable of realizing multiple speaker units through miniaturization in the computer keyboard 1 or the handrest device 2. Different from the speakers used in the traditional computer host A, the sound-emitting component 3 of the present utility model is integrated with the computer input device, which can save the space for setting external speakers in the traditional way. Moreover, by adjusting the number and setting position of the sound-emitting component 3, various sound field effects can be achieved. And because the volume of the sound-emitting component 3 is small, the high-frequency performance is good. And if the sound-emitting component 3 is set in a relatively large space inside the computer keyboard 1 or the handrest device 2, the bass effect can still be improved.

[0086] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present utility model.
