[0048] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] Please also see Figure 1-Figure 8 , the present invention provides some embodiments of a device for adjusting and testing a television speaker.

[0050] like Figure 1 As shown, the debugging device of the television speaker of the present invention comprises:

[0051] A substrate 10 is formed with a plurality of mounting positions 11;

[0052] A plurality of pressing components 20 are installed at the installation position 11;

[0053] The pressing assembly 20 is used to press at least two TV speakers 30 onto the surface of the substrate 10 ; at least two TV speakers 30 form a multi-channel speaker system.

[0054] Specifically, the debugging device of the TV speaker 30 of the present application is used to debug the TV speaker 30. The TV speaker 30 refers to a speaker used in a TV set. Usually, a TV set has at least two speakers and forms a multi-channel speaker system. The TV speaker 30 is installed on a TV housing or a TV back panel. A substrate 10 is used to imitate the TV housing or the TV back panel, and the TV speaker 30 is pressed on the surface of the substrate 10 through a pressing component 20. The TV speaker 30 is closely attached to the surface of the substrate 10. The position of the TV speaker 30 on the substrate 10 is configured with reference to the position of the TV speaker 30 relative to the TV housing or the TV back panel, which can highly simulate the actual position of the TV speaker 30 in the TV set, and the arrangement of the TV speaker 30 can be adjusted according to different models of TV sets, so as to debug the TV speakers 30 of different models of TV sets.

[0055] The present application uses a tuning device for TV speakers 30 to simulate a real application scenario of a TV to arrange the TV speakers 30 and directly tune the TV speakers 30. There is no need to tune the TV speakers 30 after the TV is completed. The TV speakers 30 can be tuned in advance, thereby improving the R&D process of the TV and improving the efficiency of sound effect debugging of the TV speakers 30.

[0056] The substrate 10 may be an insulating substrate 10, for example, a bakelite board, which is insulated, does not generate static electricity, and is not easily deformed, which is beneficial to the adjustment of the TV speaker 30. The number of mounting positions 11 is much greater than the number of press-fit components 20, and the press-fit components 20 can be installed in the corresponding mounting positions 11 as needed. Each TV speaker 30 can be equipped with at least two press-fit components 20, which is beneficial to the stable and secure position of the TV speaker 30.

[0057] In a preferred implementation of the embodiment of the present invention, a plurality of amplitude sensors are disposed on the substrate 10 for collecting amplitude data of the substrate 10 .

[0058] Specifically, when the TV speaker 30 in the TV makes a sound, it will cause the TV housing or the TV back panel to vibrate, and in severe cases, the TV housing or the TV back panel may be damaged. An amplitude sensor is installed on the substrate 10 to collect amplitude data of the substrate 10. When the TV speaker 30 on the substrate 10 makes a sound, it will also cause the substrate 10 to vibrate. The vibration data of the substrate 10 can be used to determine the vibration condition of the TV housing or the TV back panel, so as to carry out targeted design to improve the vibration resistance of the TV housing or the TV back panel and prevent vibration damage. Since the present application advances the adjustment of the TV speaker 30 before the design of the TV housing or the TV back panel is completed, it can provide a reference for the structural design of the TV housing or the TV back panel, thereby optimizing the TV housing or the TV back panel and greatly shortening the research and development process.

[0059] In a preferred implementation of the embodiment of the present invention, Figure 1-Figure 2 As shown, the debugging device also includes:

[0060] The DC source controller 60 is electrically connected to the TV speaker 30 .

[0061] Specifically, the DC source controller 60 is used to power the TV speaker 30, and the TV power board does not need to be involved in the power supply. Even if the TV power board is not designed, it does not affect the adjustment of the TV speaker 30. Through the DC source controller 60 output voltage, the TV speaker 30 can be adjusted for acoustic and electrical performance, thereby improving test efficiency and test accuracy.

[0062] In a preferred implementation of the embodiment of the present invention, Figure 1-Figure 2 As shown, the debugging device also includes:

[0063] An audio decoding system 70 connected to the television speaker 30;

[0064] The power amplifier debugging module 80 is connected to the television speaker 30 .

[0065] Specifically, the audio decoding system 70 is used to decode the audio emitted by the TV speaker 30, and the power amplifier debugging module 80 is used to debug the TV speaker 30. Therefore, the TV SoC (System on Chip) platform does not need to participate in audio decoding and debugging, and even if the TV SOC platform is not designed, it does not affect the debugging of the TV speaker 30. By configuring the DC source controller 60, the audio decoding system 70 and the power amplifier debugging module 80, not only the debugging of the TV speaker 30 is made more independent and flexible, but also it is conducive to completing the debugging of the TV speaker 30 as early as possible and with the highest possible quality.

[0066] In a preferred implementation of the embodiment of the present invention, Figure 1 , Figure 3 as well as Figure 4 As shown, the mounting position 11 adopts mounting hole units, each mounting hole unit has at least two mounting holes 111, and multiple mounting hole units are arranged in a grid shape.

[0067] Specifically, the mounting position 11 adopts a mounting hole unit, and the mounting hole unit has at least two mounting holes 111. For example, each mounting hole unit can have four mounting holes 111. There are multiple mounting hole units, and they are distributed in a grid shape to form multiple grids. Each grid can be used as a position for placing the TV speaker 30. The press-fit assembly 20 can be installed in the mounting position 11 by a locking accessory, and the locking accessory can be a nut and a bolt. The nut can be a blind hole nut, and the blind hole nut is embedded in the mounting hole 111. According to the structure of the blind hole nut, a hexagonal hole is formed at the position of the mounting hole 111 on the back of the substrate 10 to install and fix the blind hole nut. The installation reliability of the blind hole nut can also be improved by the interference fit between the mounting hole 111 and the blind hole nut, and by filling glue between the mounting hole 111 and the blind hole nut.

[0068] In a preferred implementation of the embodiment of the present invention, Figure 1 and Figure 5 As shown, the debugging device also includes:

[0069] The adapter 40 is installed at the installation position 11;

[0070] The TV base 50 is connected to the adapter 40 .

[0071] Specifically, some televisions are base-type televisions, which are supported by a television base 50. In order to make the debugging scene closer to the actual application scene of the television, the base 10 is configured with a television base 50, and the base 10 and the television base 50 are connected through the adapter 40.

[0072] The mounting hole units include first-type units and second-type units, the first-type units are used to mount the press-fit assembly 20, and the second-type units are used to mount the adapter 40. The arrangement of the mounting holes 111 in the first-type units is different from the arrangement of the mounting holes 111 in the second-type units, for example, the spacing between the mounting holes 111 in the first-type units is smaller, and the spacing between the mounting holes 111 in the second-type units is larger.

[0073] In a preferred implementation of the embodiment of the present invention, Figure 1 and Figure 5 As shown, the adapter 40 includes: a bottom 41 and a convex portion 42 connected to each other, and a plurality of first through holes 411 are formed on the bottom 41 , and a plurality of second through holes 421 are formed on the convex portion 42 .

[0074] Specifically, the adapter 40 includes a bottom 41 and a convex portion 42. The bottom 41 is connected to the substrate 10. Specifically, a first through hole 411 is formed on the bottom 41. The first through hole 411 and the mounting hole 111 (specifically, the mounting hole 111 of the second type of unit) are locked and connected by a locking member. The convex portion 42 is connected to the TV base 50. Specifically, a second through hole 421 is formed on the convex portion 42 to connect the TV base 50.

[0075] In a preferred implementation of the embodiment of the present invention, Figure 1 and Figure 5 As shown, the TV base 50 is provided with a screw hole 51 and a column 52; the position of the first through hole 411 corresponds to the position of the mounting hole 111 in the mounting hole unit, the position of the second through hole 421 corresponds to the position of the screw hole 51, and the column 52 is inserted into the second through hole 421.

[0076] Specifically, the TV base 50 is provided with a screw hole 51 and a column 52, and the position of the screw hole 51 corresponds to the position of the second through hole 421, so that a locking accessory can be locked and connected with the screw hole 51 and the second through hole 421. For example, the locking accessory can be a bolt. The column 52 passes through the second through hole 421 to position and limit the TV base 50.

[0077] In a preferred implementation of the embodiment of the present invention, Figure 6-Figure 8 As shown, the pressing assembly 20 includes:

[0078] The mounting seat 21 is formed with a third through hole 211, and the position of the third through hole 211 corresponds to the position of the mounting hole 111 in the mounting hole unit;

[0079] The first rotating member 22 and the second rotating member 23 are both rotatably disposed on the mounting seat 21;

[0080] A pressing member 24, slidably disposed on the second rotating member 23;

[0081] A connecting rod 25, both ends of which are rotatably connected to the first rotating member 22 and the second rotating member 23 respectively;

[0082] A pressing portion 251 is formed on the connecting rod 25 ; when the first rotating member 22 rotates toward the second rotating member 23 until the pressing portion 251 presses the second rotating member 23 , the pressing member 24 presses the TV speaker 30 .

[0083] Specifically, a third through hole 211 is formed on the mounting seat 21, and the third through hole 211 and the mounting hole 111 (specifically, the mounting hole 111 of the first type unit) are locked and connected by a locking accessory. The first rotating member 22 and the second rotating member 23 both rotate relative to the mounting seat 21. The rotational connection position of the first rotating member 22 and the mounting seat 21, and the rotational connection position of the second rotating member 23 and the mounting seat 21 are different. The connecting rod 25 connects the first rotating member 22 and the second rotating member 23, and the first rotating member 22 and the second rotating member 23 form a linkage structure. When the first rotating member 22 is rotated, the second rotating member 23 will be driven to rotate. Since the rotational connection positions of the two relative to the mounting seat 21 are different, the rotation angles of the two are not the same. A pressing portion 251 is formed on the connecting rod 25, which is used to press the second rotating member 23. The second rotating member 23 is pressed by the pressing portion 251, and the pressing member 24 presses the TV speaker 30.

[0084] In a preferred implementation of the embodiment of the present invention, a limiting block is further provided on the mounting seat 21 for limiting the rotation of the first rotating member 22 .

[0085] Specifically, when the first rotating member 22 rotates toward the second rotating member 23 , the pressing portion 251 limits the rotation range of the first rotating member 22 . When the first rotating member 22 rotates away from the second rotating member 23 , the limit block limits the rotation range of the first rotating member 22 .

[0086] Based on the TV speaker adjustment device described in any one of the above embodiments, the present invention also provides a preferred embodiment of a TV speaker adjustment method:

[0087] The debugging method of the debugging device of the television speaker according to the embodiment of the present invention comprises the following steps:

[0088] Step S100, determining the positions of at least two TV speakers relative to a substrate, and pressing the TV speakers onto the substrate by a pressing assembly;

[0089] Step S200: debugging the television speaker.

[0090] Specifically, when testing the TV speakers, first determine the position of the TV speakers relative to the substrate. This can be determined by the position of the TV speakers relative to the TV housing or TV back panel and the spacing between the TV speakers, so that the position of the TV speakers on the substrate is as close as possible to the actual application scenario of the TV. In order to adapt to different models of TVs, the size of the substrate is usually large. Therefore, it is also necessary to determine the position of the TV speakers relative to the substrate in combination with the spacing between the TV speakers. After determining the position of the TV speakers relative to the substrate, install the pressing assembly at the corresponding mounting position, and press the TV speakers onto the substrate. After the placement of the TV speakers is completed, the TV speakers can be tested.

[0091] The debugging method also includes:

[0092] Step S300: Acquire amplitude data of the substrate collected by the amplitude sensor, so as to set a vibration reduction structure on the TV housing based on the amplitude data.

[0093] Specifically, during the process of adjusting the TV speaker, the amplitude data of the substrate is obtained through the amplitude sensor. There can be multiple amplitude sensors distributed at various locations on the substrate. The arrangement position of the amplitude sensor is determined according to the position of the TV speaker relative to the substrate, and the amplitude sensor can be around the TV speaker.

[0094] It should be understood that the application of the present invention is not limited to the above examples.
