Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] One embodiment of the present invention provides a strong sound player, Figure 1 Schematic diagram of the structure of a powerful sound player according to an embodiment of the present invention. Figure 1 As shown, a powerful sound player according to an embodiment of the present invention comprises: a bottom disc shell 1, an upper disc shell 2, an upper sound cone 4, a sound head 5, a power amplifier unit 6, a lower sound throat 8, a lower sound cone 9, an intelligent playback control unit 11, a GPS antenna 12, a remote control antenna 13, and an audio socket 14.

[0023] The bottom dish shell 1 and the upper dish shell 2 are arc-surface shells made of lightweight and high-rigidity materials. The lower sound cone 9 is located at the top center of the bottom dish shell 1 and is seamlessly connected. The lower sound throat 8 is located at the bottom center of the upper dish shell 2. The upper dish shell 2 is located above the bottom dish shell 1. The lower sound throat 8 is opposite to the lower sound cone 9 and there is a sound-emitting gap between the two. The sound head 5 is installed in the upper dish shell 2. The sound waves generated by the sound head 5 are emitted from the gap between the lower sound throat 8 and the lower sound cone 9, and radiate outward through the gap between the upper dish shell 2 and the bottom dish shell 1.

[0024] The intelligent playback control unit 11 is installed in the bottom disc shell 1, and is connected to the GPS antenna 12, the remote control antenna 13 and the audio socket 14. The intelligent playback control unit 11 receives the standard time and geodetic coordinates through the GPS antenna 12, and receives the remote control command and transmits the sound signal and other data through the remote control antenna 13, so as to realize the timed playback, the selection of the track to be played and the volume control. The intelligent playback control unit 11 is connected to the audio socket 14 for accessing the external sound signal, and the playback sound signal output by the intelligent playback control unit 11 is connected to the power amplifier unit 6 installed in the upper disc shell 2, and the power amplifier unit 6 connects the power-amplified signal to the sound head 5 to emit the sound, and the sound emitted by the sound head 5 is emitted from the lower sound throat 8, and the sound wave enters the gap between the upper disc shell 2 and the bottom disc shell 1 through the gap between the lower sound throat 8 and the lower sound cone 9 to radiate the sound isotropically outward.

[0025] The gap between the upper dish shell 2 and the bottom dish shell 1 forms an isotropic first sound horn, which is designed as an exponential horn (exponential sound radiator) with a winding coefficient close to 15 and an area ratio close to 150 times. It has a wide-band low-misalignment isotropic radiation characteristic and is made of high-rigidity materials and is suitable for strong sound waves with a sound source level of 174dB@1m.

[0026] The strong sound player of the above embodiment of the present invention may further include a sealing plate 10 and a hollow support column 7. The bottom dish shell 1 has an operation installation hole for operating or installing components installed on the bottom dish shell 1, the sealing plate 10 is used to block the operation installation hole of the bottom dish shell 1, and the hollow support column 7 is used to connect and fix the bottom dish shell 1 and the upper dish shell 2.

[0027] The hollow support columns 7 are small in size and are multiple, close to the edges of the bottom dish shell 1 and the upper dish shell 2 and evenly arranged along the circumference of the bottom dish shell 1 and the upper dish shell 2, which can ensure the same support in all directions. The hollow support columns 7 are hollow for passing the signal line and have upper and lower connected mounting screw holes, which can realize the stacking installation of multiple dish shells.

[0028] The working principle of the loudspeaker of the above embodiment of the present invention is as follows: Figure 2 As shown, the external sound signal is connected to the intelligent playback control unit 11 through the audio socket 14, and the intelligent playback control unit 11 receives the GPS signal through the GPS antenna 12 to obtain the standard time and GPS coordinates. The intelligent playback control unit 11 outputs the sound signal to be played to the power amplifier unit 6 according to the remote control command. The intelligent playback control unit 11 selects the playback track according to the remote control command received through the remote control antenna 13, controls the playback volume, and determines the time to start playback. The output signal of the power amplifier unit 11 is connected to the sound head 5 to emit sound, and the sound is emitted from the gap between the lower throat 8 and the lower sound cone 9, and then the sound is broadcast outward through the isotropic radiator formed between the upper disc shell 2 and the bottom disc shell 1. The intelligent playback control unit 11 and the power amplifier unit 6 can be connected to an external AC power supply.

[0029] The loudspeaker of one embodiment of the present invention is a dual-disc integrated wide-band low-detuning isotropic loudspeaker. Another embodiment of the present invention provides a multi-disc integrated wide-band low-detuning isotropic loudspeaker. Figure 3 As shown, based on the strong sound player of the above embodiment of the present invention, the strong sound player of another embodiment of the present invention further includes: a superimposed disc shell 3, the superimposed disc shell 3 is installed on the upper disc shell 2, the superimposed disc shell 3 is a curved shell made of a lightweight and high-rigidity material, the superimposed disc shell 3 has the same structure as the upper disc shell 2, and the gap between the superimposed disc shell 3 and the upper disc shell 2 forms an isotropic second sound-emitting speaker, and the second sound-emitting speaker is an exponential speaker with a winding coefficient close to 15 and an area ratio close to 150 times.

[0030] In this embodiment, the strong sound player further includes: an upper sound throat 15, which is located at the bottom center of the stacked disc shell 3, and a sound channel is formed between the upper sound throat 15 and the upper sound cone 4.

[0031] In this embodiment, the stacked dish shell 3 and the upper dish shell 2 have the same structure. There is a sound outlet gap between the upper sound throat 15 at the lower part of the stacked dish shell 3 and the upper sound cone 4 at the top center of the upper dish shell 2 to form a sound channel. The lower part of the stacked dish shell 3 and the upper part of the upper dish shell 2 form an isotropic second sound horn, which is the same as the first sound horn, and the more such identical structures are stacked, the stronger the sound.

[0032] The other structures and functions of this embodiment are the same as those of the above-mentioned embodiment, and will not be described in detail here. In this embodiment, the stacked disc shell 3 is installed on the upper disc shell 2 and also forms an exponential speaker, which is equivalent to adding a strong sound player to improve the total sound pressure level, and the more the number of stacked disc shells of the same structure is, the higher the total sound pressure level is. That is, more disc shells of the same structure can be stacked on the stacked disc shell 3 to improve the total sound pressure level.

[0033] In the above another embodiment, the bottom dish shell 1, the upper dish shell 2 and the stacked dish shell 3 are arc-surface shells made of lightweight and high-rigidity materials, and are connected and fixed by the hollow support columns 7. The gaps between the two form isotropic exponential sound radiators, and when the winding coefficient is close to 15 and the area ratio is close to 150 times, low-detuning wide-band sound playback can be achieved, and the use of lightweight and high-rigidity materials can radiate strong sound waves with a sound source level of 174dB@1m.

[0034] In the above another embodiment, the arc surfaces of the upper dish shell 2, the bottom dish shell 1, and the stacked dish shell 3 are completely identical and have good rigidity. The upper dish shell 2 and the bottom dish shell 1 are fixed by the hollow support column 7, and the stacked dish shell 3 and the upper dish shell 2 can be fixed by hollow support columns of the same height, thereby forming two identical upper and lower sound radiators.

[0035] The multi-disc integrated broadband low-detuning isotropic high-power sound player proposed in another embodiment of the present invention can also be installed upside down and suspended for use, such as Figure 4 That is, the stacked disc shell 3 is at the bottom and the bottom disc shell 1 is at the top. The effect of playing strong sound waves in this hanging installation method is essentially the same as that of the forward installation, and it can also radiate strong sound waves with a sound source level of 174dB@1m.

[0036] The high-power sound player of the above-mentioned embodiment of the present invention is a relatively closed high-power sound wave sound-generating device, which can emit low-detuned high-power sound waves with a sound source level of 174dB@1m. It can receive external sound signals for sound generation like a general speaker, and can also receive sound signals transmitted by remote control wirelessly for sound generation, adjust the sound generation time and intensity according to remote control commands, and select tracks.

[0037] In the above embodiment of the present invention, the power amplifier unit 6 and the sound head 5 are installed in the upper disc shell 1, and the intelligent playback control unit 11 is installed in the bottom disc shell 1. There are no accessories outside the disc, and the player can be played by wireless remote control. The bottom disc shell 1 is a non-conductive material, which has no shielding effect on radio signals and will not hinder the player from receiving GPS signals and remote control signals.

[0038] The hollow support column 7 is hollow and can be threaded to achieve signal connection and power line connection between the dish shells. The bottom dish shell 1 and the upper dish shell 2 form an exponential radiator, and the upper dish shell 2 and the superimposed dish shell 3 form the same exponential radiator. When the exponential speaker is designed with a winding coefficient close to 15 and an area ratio close to 150 times, it has a wide-band low-detuning isotropic radiation characteristic. It is made of high-rigidity materials and can be used for strong sound waves with a sound source level of 174dB@1m.

[0039] The above embodiment of the present invention provides a high-power sound player with a wide frequency range, low full-scale distortion, isotropic sound radiation, a maximum output sound source level of 174dB@1m, and an integrated structure. Compared with the prior art, the high-power sound player of the above embodiment of the present invention has at least the following advantages:

[0040] 1. The present invention adopts an exponential radiator formed between the dish shells, and when designed as an exponential speaker with a winding coefficient close to 15 and an area ratio close to 150 times, it has a wide-band low-misalignment isotropic radiation characteristic. It is made of lightweight and high-rigidity materials and can be suitable for strong sound waves with a sound source level of 174dB@1m.

[0041] 2. The present invention installs the intelligent playback control unit, the power amplifier unit, and the sound head all inside the disc shell, with no accessories outside the disc. Playback is achieved through wireless remote control, which reduces the complexity of installation and use.

[0042] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
