[0024] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments, but the implementation of the present invention is not limited thereto.
[0025] Please see Figures 1 to 7The present invention relates to a television set 100 with a horizontally placed speaker, comprising: a television set body 10 and a horizontally placed speaker 20. The horizontally placed speaker 20 includes: a speaker housing 21, a crossover circuit board (not shown), a first tweeter 22, a first mid-bass speaker 23, a bass reflex port 24, a second tweeter 25, a second mid-bass speaker 26, a left sealing cover 27, and a right sealing partition 28. The speaker housing 21 is horizontally and fixedly connected to the bottom of the television set body 10 in the left-right direction. Alternatively, in this embodiment, the speaker housing 21 is threadedly fastened to the bottom of the television set body 10 by vertically arranged bolts 21a to simplify the connection structure and make the structure simpler and more compact. The speaker housing has a long strip structure, and a hollow channel 211 extending in the left-right direction is formed inside the speaker housing 21. The left sealing cover 27 is fixedly sealed to the left end of the hollow channel 211, and the right sealing partition 28 is internally sealed within the hollow channel 211. The hollow channel 211 forms a sealed cavity 2111 between the left sealing cover 27 and the right sealing partition 28. The front side wall of the speaker housing 21 is provided with a first mounting hole 212, a second mounting hole 213, a third mounting hole 214, a fourth mounting hole 215, and a fifth mounting hole 216. The first mounting hole 212, the second mounting hole 213, the third mounting hole 214, the fourth mounting hole 215, and the fifth mounting hole 216 all extend through the sealed cavity 2111 in the front-back direction. The first mounting hole 212, the second mounting hole 213, the third mounting hole 214, the fourth mounting hole 215, and the fifth mounting hole 216 are distributed sequentially from left to right between the left sealing cover 27 and the right sealing partition 28. The first tweeter 22 is fixedly installed in the first mounting hole 212, the first mid-bass speaker 23 is fixedly installed in the second mounting hole 213, the bass reflex port 24 is fixedly installed in the third mounting hole 214, the second tweeter 25 is fixedly installed in the fourth mounting hole 215, and the second mid-bass speaker 26 is fixedly installed in the fifth mounting hole 216. This makes the installation layout of the first tweeter 22, the first mid-bass speaker 23, the bass reflex port 24, the second tweeter 25, and the second mid-bass speaker 26 more reasonable. The crossover circuit board is built-in and fixed in the speaker enclosure 21. The input terminal of the crossover circuit board is electrically connected to the output terminal of the power amplifier unit in the main body of the television 10; the tweeter output terminal of the crossover circuit board is electrically connected to the first tweeter 22 and the second tweeter 25, and the mid-bass output terminal of the crossover circuit board is electrically connected to the first mid-bass speaker 23 and the second mid-bass speaker 26. Therefore, the speaker housing 21 has a larger installation space and is not limited by the geometry and volume of the TV body 10. There is enough space to install more tweeters and mid-bass speakers, making the speaker installation structure layout more perfect and reasonable, and the assembly more convenient.Furthermore, the power amplifier unit inside the TV body 10 outputs a full-range audio signal to the crossover circuit board. The crossover circuit board divides the full-range signal into high-frequency and mid-low-frequency signals. The high-frequency signal is output to the first tweeter 22 and the second tweeter 25, and the mid-low-frequency signal is output to the first mid-bass speaker 23 and the second mid-bass speaker 26. The first tweeter 22, the second tweeter 25, the first mid-bass speaker 23, and the second mid-bass speaker 26 respectively convert the received high-frequency and mid-low-frequency signals into sound, making the frequency band more accurately covered. Even when reproducing complex sound effects, it can better cover all frequency response ranges, avoiding sound effect loss and producing clearer and more distinct sound layers. There is no need to add an additional power amplifier unit inside the speaker housing 21, making the structure simpler and more compact, thereby reducing the manufacturing cost of the horizontal speaker 20. A larger sealed cavity 2111 is formed inside the speaker housing 21, creating a larger air vibration space, and the addition of a bass reflex port 24 enhances the low-frequency output, resulting in better sound quality. This allows for better sound quality that meets people's requirements, eliminating the need to spend a lot of money to buy separate speakers to use with the TV, thus saving on operating costs and avoiding the cumbersome installation and usage experience of buying separate speakers. It makes the TV simpler and more convenient to use. Specifically, as follows:
[0026] Please see Figure 3 , Figure 4 , Figure 6 and Figure 7The bass reflex tube 24 has a hollow tubular structure extending through both ends. Specifically, in this embodiment, the left end of the bass reflex tube 24 bends forward to form a forward-facing left opening end 241, and the right end of the bass reflex tube 24 extends from left to right and is suspended within the sealed cavity 2111, forming a right opening end 242 facing right. When the diaphragms of the first tweeter 22, the first mid-bass speaker 23, the second tweeter 25, and the second mid-bass speaker 26 move forward, they compress the air in front (generating a positive sound wave) and simultaneously cause the air inside the sealed cavity 2111 to expand (pressure decrease). At this time, external air is drawn into the bass reflex tube 24 and into the sealed cavity 2111. When the diaphragms of the first tweeter 22, the first mid-bass speaker 23, the second tweeter 25, and the second mid-bass speaker 26 move backward, the air inside the sealed cavity 2111 is compressed (pressure increases). At this time, the high-pressure air inside the sealed cavity 2111 is discharged outward through the bass reflex port 24. The sound wave energy generated behind the first tweeter 22, the first mid-bass speaker 23, the second tweeter 25, and the second mid-bass speaker 26 vibrates and propagates within the sealed cavity 2111. This energy is then effectively radiated out through the bass reflex port 24 and superimposed in phase with the sound waves in front of the first tweeter 22, the first mid-bass speaker 23, the second tweeter 25, and the second mid-bass speaker 26, thereby significantly increasing the sound pressure level of specific low frequencies and achieving a stronger, deeper bass effect.
[0027] Please see Figure 6 and Figure 7 A mounting base plate 243 protrudes outward from the sidewall of the left opening end 241, and the mounting base plate 243 is fixedly connected to the sidewall of the third mounting hole 214. The mounting base plate 243 allows the phase inverter tube 24 to be more firmly and stably fixed to the sidewall of the third mounting hole 214, resulting in a more robust and reliable structure. Preferably, in this embodiment, a connecting support wall 244 protrudes rearward from the rear side of the mounting base plate 243, and the rear end of the connecting support wall 244 is integrally formed and connected to the outer sidewall of the phase inverter tube 24. This enhances the overall structural robustness and stability of the phase inverter tube 24, preventing accidental breakage of the phase inverter tube 24, resulting in a more robust and rational structure.
[0028] Please see Figures 1 to 3The television set 100 with a horizontally placed speaker of this utility model further includes: a front grille 29; an upper mounting wall 217 is formed by the top of the front side of the speaker housing 21 extending horizontally forward; a lower mounting wall 218 is formed by the bottom of the front side of the speaker housing 21 extending horizontally forward; and the front grille 29 is fixedly embedded between the upper mounting wall 217 and the lower mounting wall 218. By setting the front grille 29, the exposed front portions of the first tweeter 22, the first mid-bass speaker 23, the bass reflex port 24, the second tweeter 25, the second mid-bass speaker 26, the left sealing cover 27, and the right sealing partition 28 can be better protected, making the structure safer and more reasonable. In detail, in this embodiment, the bottom of the upper mounting wall 217 has an upper engaging groove 2171 arranged through the left and right directions, and the top of the lower mounting wall 218 has a lower engaging groove 2181 arranged through the left and right directions. The lower engaging groove 2181 is vertically aligned with the upper engaging groove 2171, and the front mesh cover 29 is engaged and fixed between the upper engaging groove 2171 and the lower engaging groove 2181. This achieves a fixed fit between the upper mounting wall 217 and the lower mounting wall 218, and the safety structure is simple and reasonable.
[0029] Please see Figure 3 , Figure 4 and Figure 6 The television set 100 with a horizontally placed speaker of this utility model also includes an infrared remote control receiver module 30. The infrared remote control receiver module 30 is fixed to the front side wall of the speaker housing 21, and the signal receiving window of the infrared remote control receiver module 30 faces the mesh of the front grille 29. The infrared remote control receiver module 30 is electrically connected to the main board inside the television set 10. This allows the remote control signal to pass through the mesh of the front grille 29 and reach the signal receiving window of the infrared remote control receiver module 30, enabling the infrared remote control receiver module 30 to receive the remote control signal and control the operation of the television set 10. The structural layout is more reasonable.
[0030] Please see Figures 1 to 6The television set 100 with a horizontally placed speaker of this utility model further includes: a power switch module 40, a power support cover 50, and a power cover 60. The power cover 60 is fixedly connected to the right end of the hollow channel 211. The hollow channel 211 forms an installation cavity 2112 between the right sealing partition 28 and the power cover 60. The power support cover 50 is fixedly built into the installation cavity 2112. The power switch module 40 is fixed on the power support cover 50 and is electrically connected to the main board inside the television set 10. A first button 51 with elastic suspension is formed on the power support cover 50, and the left side of the first button 51 directly abuts against the power switch module 40. A second button 61 with elastic suspension is formed on the power cover 60, and the left side of the second button 61 directly abuts against the right side of the first button 51. By pressing the second elastically suspended button 61 and pushing the first elastically suspended button 51, the power switch module 40 can be triggered to control the power on or off of the TV body 10, making the operation more convenient and aesthetically pleasing.
[0031] Therefore, the infrared remote control receiver module 30 and power switch module 40, which are traditionally integrated and installed on the main body of the TV 10, are redesigned and relocated to the speaker housing 21. This avoids the signal reception of the infrared remote control receiver module 30 and the switching operation of the power switch module 40 being blocked by the addition of the horizontal speaker 20. This ensures that the infrared remote control receiver module 30 can normally receive the remote control signal emitted by the TV remote control to control the operation of the main body of the TV 10, and facilitates the operation of the power switch module 40 to control the power on or off of the main body of the TV 10. This makes it more convenient to use and the structural layout is more reasonable.
[0032] In a preferred embodiment, a first clearance hole 219 is formed on the top of the speaker housing 21, and a second clearance hole (not shown) is formed on the bottom of the television body 10. The first clearance hole 219 is vertically aligned with and connected to the second clearance hole. The conductive wires of the frequency division circuit board, the infrared remote control receiver module 30, and the power switch module 40, which are electrically connected to the inside of the television body 10, pass through the first clearance hole 219 and the second clearance hole, thus preventing the conductive wires from being exposed. The structural layout is safer and more reasonable.
[0033] It should be noted that, in this utility model, the specific structure and working principle of the power amplifier unit inside the television body 10, the specific structure and working principle of the crossover circuit board, the specific connection circuit principle and working principle of the first tweeter 22, the first mid-bass speaker 23, the second tweeter 25 and the second mid-bass speaker 26 electrically connected to the crossover circuit board, the specific connection circuit principle and working principle of the crossover circuit board electrically connected to the power amplifier unit inside the television body 10, and the specific connection circuit principle and working principle of the infrared remote control receiver module 30 and the power switch module 40 electrically connected to the main board inside the television body 10 are all conventional technical means well known to those skilled in the art, and therefore will not be described in detail here.
[0034] Please see Figures 2 to 6 The right side of the front end of the left sealing cover 27 abuts against the left side of the front mesh cover 29, and the left side of the front end of the power cover 60 abuts against the right side of the front mesh cover 29. Thus, the left sealing cover 27 and the power cover 60 together block and limit the left and right sides of the front mesh cover 29, preventing the front mesh cover 29 from falling out of the upper engaging groove 2171 and the lower engaging groove 2181, making the structure safer and more reliable.
[0035] The working principle of the television set 100 with a horizontally placed speaker of this utility model will be described in detail with reference to the accompanying drawings:
[0036] In use, pressing the second button 61 pushes the first button 51, which is elastically suspended, to trigger the power switch module 40 to turn on the TV body 10. After the TV body 10 is turned on, the power amplifier unit inside the TV body 10 outputs a full-range audio signal to the crossover circuit board. The crossover circuit board divides the full-range signal into high-frequency signals and mid-low-frequency signals. The high-frequency signal is output to the first tweeter 22 and the second tweeter 25, and the mid-low-frequency signal is output to the first mid-low-frequency speaker 23 and the second mid-low-frequency speaker 26. The first tweeter 22, the second tweeter 25, the first mid-low-frequency speaker 23, and the second mid-low-frequency speaker 26 respectively convert the received high-frequency signal and mid-low-frequency signal into sound and play it out.
[0037] Since the speaker housing 21 in this utility model is horizontally fixedly connected to the bottom of the television body 10 in the left-right direction, the speaker housing 21 has a long strip structure, and a hollow channel 211 extending in the left-right direction is formed inside the speaker housing 21. The left sealing cover 27 is fixedly sealed to the left end of the hollow channel 211, and the right sealing partition 28 is internally sealed inside the hollow channel 211. The hollow channel 211 forms a sealed cavity 2111 between the left sealing cover 27 and the right sealing partition 28. The front wall of the speaker housing 21 has a first mounting hole 212, a second mounting hole 213, a third mounting hole 214, a fourth mounting hole 215, and a fifth mounting hole 216. These mounting holes 212, 213, 214, 215, and 216 all extend through the sealed cavity 2111 in the front-to-back direction. They are distributed sequentially from left to right between the left sealing cover 27 and the right sealing partition 28. A first tweeter 22 is fixedly installed in the first mounting hole 212, a first mid-bass speaker 23 is fixedly installed in the second mounting hole 213, a bass reflex port 24 is fixedly installed in the third mounting hole 214, a second tweeter 25 is fixedly installed in the fourth mounting hole 215, and a second mid-bass speaker 26 is fixedly installed in the fifth mounting hole 216. The crossover circuit board is built into the speaker housing 21. The input of the crossover circuit board is electrically connected to the output of the power amplifier unit inside the television body 10. The tweeter output of the crossover circuit board is electrically connected to the first tweeter 22 and the second tweeter 25, and the mid-bass output of the crossover circuit board is electrically connected to the first mid-basser 23 and the second mid-basser 26. Therefore, the speaker housing 21 has a larger installation space and is not limited by the geometry and volume of the television body 10. It has sufficient space to install a larger number of tweeters and mid-bassers, making the speaker installation structure layout more complete and reasonable, and assembly more convenient. Furthermore, the power amplifier unit inside the television body 10 outputs a full-range audio signal to the crossover circuit board. The crossover circuit board divides the full-range signal into high-frequency and mid-low-frequency signals. The high-frequency signal is output to the first tweeter 22 and the second tweeter 25, and the mid-low-frequency signal is output to the first mid-bass speaker 23 and the second mid-bass speaker 26. The first tweeter 22, the second tweeter 25, the first mid-bass speaker 23, and the second mid-bass speaker 26 respectively convert the received high-frequency and mid-low-frequency signals into sound, enabling more precise frequency band coverage. Even when reproducing complex sound effects, it can better cover the entire frequency response range, avoiding sound effect loss and producing clearer and more distinct sound layers. There is also no need to add an additional power amplifier unit inside the speaker housing 21, making the structure simpler and more compact, thereby reducing the manufacturing cost of the horizontal speaker 20.A larger sealed cavity 2111 is formed within the speaker housing 21, creating a larger air vibration space. The addition of a bass reflex port 24 enhances low-frequency output, resulting in better sound quality. This allows the sound quality to better meet user requirements, eliminating the need to purchase separate speakers for the television, thus saving on operating costs and avoiding the cumbersome installation and usage experience associated with buying separate speakers. The result is simpler and more convenient to use, significantly improving the user experience.
