The technical components of the multifunctional portable bluetooth speaker 1 include a microphone 10, a speaker body 20 and a waterproof silicone sleeve 30. The structure and function of each technical element are described below with reference to the related drawings.

The microphone 10 is a technical element in signal communication with the speaker body 20, and a user can operate the technical element to generate sound from the speaker body 20. Referring to fig. 2 to 4, fig. 2 is an external side view of the microphone 10, fig. 3 is an external bottom view of the microphone 10, and fig. 4 is a circuit block diagram of the microphone 10. The microphone 10 includes a housing 11, a radio module 12, a microphone-side U-band communication module 13, a microphone-side bluetooth communication module 14, a microphone-side power module 15, and a microphone-side control module 16. The housing 11 is used for enclosing and protecting electronic components therein, and is used for holding and operating by a user. An open end 111 is formed above the housing 11, and a porous metal housing 112 is fixed in the open ends 111. The side of the shell 11 is fixedly connected with a plurality of control keys. In this embodiment, there are a first control button 1131, a second control button 1132, a third control button 1133, a fourth control button 1134 and a fifth control button 1135. Operating each control button switches the microphone 10 on or off, or adjusts the electrical signal transmitted by the microphone 10, as will be explained below. A sliding key 1136 is disposed under the control button of the housing 11, and the sliding key 1136 can be switched between a first end 11361 and a second end 11362, so that the microphone 10 can use different signal transmission modes. A microphone-side USB socket 114, a fixing hook 115, a microphone-side audio transceiver jack 116, and a microphone-side audio receiver jack 117 are mounted on the lower side of the housing 11. The microphone end USB slot 114 is a USB Type-C slot and can be plugged with a USB Type-C plug. The difference between the microphone-side audio transceiver jack 116 and the microphone-side audio receiver jack 117 are 3.5 audio jacks, in which the former can receive external music signals (which may be digital or analog) and transmit music signals to the outside, and the latter can only transmit music signals to the outside in one direction, under the operation of the control circuit.

The housing 11 includes more than one circuit board and a plurality of fixing ribs (not shown), the circuit board has a plurality of active and passive components gathered thereon, wherein a set of parts can provide a specific function, and the set of the components is called a module. Some of the modules are in signal communication with and controlled by components on the housing 11. Please see fig. 4. The sound receiving module 12 is installed in the housing 11, and converts an external sound into a sound signal through the porous metal housing 112. In practice, the sound receiving module 12 may be a single sound receiving unit, which can convert the vibration waveform of the sound into a corresponding electrical signal, i.e. the sound signal. The electrical signals may be digital or analog. In use, the voice of the user speaking or singing is received by the radio module 12 for subsequent processing. The microphone-side U-band communication module 13 is used for transmitting and receiving the sound signal converted by sound, and the transmission object is a U-band communication module in the speaker body 20. The U band is an Ultra High Frequency (UHF) band, and the signal Frequency varies from 300MHz to 3 GHz. In use, the sound signal is transmitted unidirectionally. The microphone-side bluetooth communication module 14 is also installed in the housing 11 and is capable of being connected to a plurality of external bluetooth devices. According to the requirement of the present invention, the external bluetooth device can be connected to an audio/video streaming website, a live broadcast website or a karaoke website, and the electronic device having a bluetooth communication module for signal connection with the microphone-side bluetooth communication module 14 can be but not limited to a smart phone, a tablet computer, a desktop computer or a notebook computer.

The microphone end power module 15 is installed in the casing 11, and the microphone end power module 15 is electrically connected with the microphone end U-band communication module 13, the microphone end bluetooth communication module 14 and the sound receiving module 12 to transmit power to electrically connected components. In practice, the microphone-side power module 15 includes at least one secondary battery. The manner in which the electrical connections are depicted in the drawings is indicated by thick solid lines, as opposed to signal connections through connecting wires, which are indicated by thick solid lines. In addition, the microphone-side power module 15 is also electrically connected to the microphone-side USB socket 114, but unlike other electrical connection elements, the microphone-side power module 15 receives external power from the microphone-side USB socket 114 and stores the external power. That is, the microphone-side USB socket 114 is a power supply for the microphone-side power module 15.

The microphone-side control module 16 is a main component of the operation of the microphone 10. The microphone end control module 16 is installed in the housing 11, the microphone end control module 16 is electrically connected to the microphone end power module 15 in a switchable manner, and the microphone end control module 16 is in signal connection with the microphone end bluetooth communication module 14, the microphone end U-band communication module 13, the sound receiving module 12, the microphone end USB slot 114, the control keys, the sliding key 1136, the microphone end audio source transceiving jack 116 and the microphone end audio source receiving jack 117. The microphone-side control module 16 may perform some operations. First, the microphone-side control module 16 is operated by the first control button 1131 to turn on or off the operation, so as to turn on or off the microphone 10. Preferably, the first control button 1131 is pressed for a long time (e.g., three seconds) to turn on or off the microphone 10. Second, the second control key 1132 is operated (short-pressed) to increase the volume of the sound signal, so as to control the speaker body 20 to increase the volume of the sound corresponding to the sound signal. Third, the third control key 1133 is operated (pressed for a short time) to reduce the volume of the sound signal, so as to control the speaker body 20 to reduce the volume of the sound corresponding to the sound signal. Fourth, it is operated (short-pressed) by the fourth control key 1134 to increase an echo (echo) effect in the sound signal. Fifth, the fifth control key 1135 is operated (short-pressed) to reduce the echo effect in the sound signal. Sixth, when the sliding key 1136 slides to the first end 11361, the microphone end control module 16 will start the microphone end U-band communication module 13 and block the signal transmission of the microphone end audio source transceiving jack 116 and the microphone end audio source receiving jack 117, and when the sliding key slides to the second end 11362, the microphone end control module 16 closes the microphone end U-band communication module 13 and resumes the signal transmission of the microphone end audio source transceiving jack 116 and the microphone end audio source receiving jack 117. In other words, when the sliding key 1136 is located at the first end 11361, the microphone 10 and the speaker body 20 are in wireless signal communication through the U-band; when the slide key 1136 is located at the second end 11362, the microphone 10 and the speaker body 20 are in wired signal communication via a signal line. In addition to the above operations for external interaction, the microphone-side control module 16 also manages the basic preset functions of the microphone-side bluetooth communication module 14, the microphone-side U-band communication module 13, and the radio module 12.

Further, the microphone audio receiving/transmitting jack 116 and the microphone audio receiving jack 117 can be respectively plugged with an earphone audio plug (not shown). In practice, the earphone sound source plug is a 3.5 audio connector. When the earphone sound source plug is plugged into the microphone end sound source transceiving jack 116, the microphone end control module 16 will transmit the sound signal to the outside through the earphone sound source plug, or receive the music signal from the earphone sound source plug (from the music transmitting end, such as a smart phone); when the earphone sound source plug is inserted into the microphone-side sound source receiving jack 117, the microphone-side control module 16 transmits the sound signal or the received music signal to the outside through the earphone sound source plug.

Referring to fig. 5 to 9, fig. 5 is an exploded view of a housing structure 21 of the speaker body 20, fig. 6 to 8 are different external views of a lower housing 211 of the housing structure 21, and fig. 9 is a circuit diagram of electronic components inside the speaker body 20.

As shown in fig. 5, the casing structure 21 has a nearly circular appearance in a top view, which protects the components therein and facilitates the sound emitted from the speaker to pass through to the outside. The housing structure 21 includes the aforementioned lower shell 211, an upper cover 212 and a sound-permeable porous cover plate 213. A microphone receiving groove 2111 is formed in the lower case 211 to receive the microphone 10. As shown in fig. 7, an open end 21111 of the microphone accommodating groove 2111 is formed on the side wall of the lower case 211, and the open end 21111 is used for allowing the microphone 10 to enter the microphone accommodating groove 2111. A plurality of operation buttons, a speaker-end USB slot 2112, a display lamp 2116, and a speaker-end sound source receiving jack 2117 are mounted on the side wall of the lower case 211. In this embodiment, there are three operation buttons: a first manipulation button 2113, a second manipulation button 2114, and a third manipulation button 2115.

The upper cover 212 is connected above the lower cover 211, and two openings are opened above the upper cover 212: a first opening 2121 and a second opening 2122. The first opening 2121 is large and may have a mesh disposed thereon. The first opening 2121 and the second opening 2122 are for allowing the corresponding speaker sound to be emitted from the upper cover 212 to the outside. A sound-permeable cover plate 213 is mounted over the top cover 212 to cover the two openings, which is intended to protect the two openings but not to block the transmission of sound (through the openings).

The mid-low frequency horn 22 is installed inside the lower case 211 to face the first opening 2121. The high-frequency horn 23 is also mounted inside the lower case 211, facing the second opening 2122.

The housing structure 21 has a circuit board 2118 therein. As with the microphone 10, the circuit board 2118 has a collection of active and passive components, some of which may provide specific functions, the collection of which are referred to as a module. The circuit board 2118 includes a speaker end bluetooth communication module 24, a speaker end U-band communication module 25, a speaker end power module 26, and a speaker end control module 27. The elements with which these modules interact are illustrated in fig. 8. The speaker-end bluetooth communication module 24 is installed inside the lower case 211 and is in signal connection with several external bluetooth devices (the same as those connected to the microphone 10) to receive music signals. Loudspeaker end U frequency channel communication module 25 is installed inside inferior valve 211, and loudspeaker end U frequency channel communication module 25 and microphone end U frequency channel communication module 13 wireless connection, loudspeaker end U frequency channel communication module 25 are used for receiving the sound signal who comes from microphone end U frequency channel communication module 13. The horn end power module 26 is electrically connected with the middle-low frequency horn 22, the high-frequency horn 23, the horn end bluetooth communication module 24 and the horn end U-band communication module 25, so as to transmit electric power to the electrically connected elements. The speaker-side power module 26 is also electrically connected to the speaker-side USB socket 2112, but unlike other electrical connection elements, the speaker-side power module 26 receives external power from the speaker-side USB socket 2112 and stores the external power. That is, the speaker-end USB socket 2112 is a power supply for the speaker-end power module 26. In practice, the horn-end power module 26 also uses a secondary battery as a storage and discharge element. The horn end control module 27 is a main component of the operation of the horn body 20. The horn end control module 27 is switchably and electrically connected to the horn end power module 26, and is connected to the horn end bluetooth communication module 24, the horn end U-band communication module 25, the low and medium frequency horn 22, the high frequency horn 23, the horn end USB slot 2112, and these control buttons, so as to perform the following operations. First, the speaker body 20 is turned on or off by the operation of the first control button 2113 (e.g. pressing for three seconds). Second, when the second control button 2114 is operated (for example, by short-pressing), the speaker-end bluetooth communication module 24 is controlled to be in signal connection with any of these external bluetooth devices (when no music signal is transmitted), and the music signal transmitted by the external bluetooth device connected to the speaker 23 is played or paused through the middle/low frequency speaker 22 or the actual sound corresponding to the sound signal transmitted by the microphone-end U-band communication module 13 is played. Preferably, the second control button 2114 is connected to a multi-color LED lamp (not shown) for indicating the operation status of the second control button 2114 with different colors and flashing, such as blue flashing for indicating waiting connection and red continuous for indicating music playing. And a third manipulation button 2115 (e.g., short-press) for canceling or restoring the vocal part of the music signal. Thus, when the user is matched with the actual music played by the music signal, the original singing and radio reception can be eliminated, so that the user can enjoy the interest of singing. When the third manipulation button 2115 is pressed a short time after the voice is removed, the voice is restored. Note that the sound volume is not under the control of the speaker body 20, but is controlled by the microphone 10 (controlling human voice) or an external bluetooth device (controlling music) connected.

Referring to fig. 8, the upper cover of the microphone accommodating groove 2111 in fig. 7 is removed, and the internal design of the microphone accommodating groove 2111 is shown. A USB charging plug 21113 is mounted on a closed end 21112 of the microphone accommodating groove 2111. The USB charging plug 21113, the display lamp 2116 and the horn-end power module 26 are electrically connected. When the microphone 10 is placed in the microphone accommodating groove 2111 and the microphone-side USB socket 114 is electrically connected to the USB charging plug 21113, the speaker-side power module 26 charges the microphone 10 and the display lamp 2116 is turned on. Thus, the user can know the current position and status of the microphone 10. In addition, an elastic hook 21114 corresponding to the fixing hook 115 is installed inside the closed end 21112 of the microphone accommodating groove 2111. When the microphone 10 is inserted into the microphone accommodating groove 2111, the elastic catch 21114 catches on the fixing hook 115, and when the microphone 10 is pressed, the elastic catch 21114 releases the fixing hook 115 and ejects the microphone 10.

The aforementioned speaker-end sound source receiving jack 2117 is also in signal connection with the speaker-end control module 27, so that the speaker-end control module 27 can play or pause the actual music corresponding to the music signal transmitted from an audio source plug (3.5 audio connector) inserted into the speaker-end sound source receiving jack 2117 through the middle and low frequency speakers 22 and the high frequency speakers 23. That is, the music signal can be inputted into the speaker body 20 through the speaker-end bluetooth communication module 24 for playing, and can also be inputted into the speaker body 20 through a conventional audio cable in a wired manner.

Referring to fig. 10 and 11, fig. 10 shows the waterproof silicone rubber cover 30 removed from the speaker body 20, and fig. 11 further shows a lifting strap 31 removed from the speaker body 20. The waterproof silicone sleeve 30 is sleeved on the outer part of the sound-transparent porous cover plate 213 of the covering shell structure 21, so that the speaker body 20 sleeved with the waterproof silicone sleeve 30 cannot shield the sound generated by the speaker by the waterproof silicone sleeve 30. The waterproof silicone sleeve 30 can provide a certain waterproof function to the covered portion, and also protect the speaker body 20 against a certain degree of impact. A plurality of suction cups 32 (e.g. 4) are disposed below the waterproof silicone sheath 30 for detachably fixing the speaker body 21 on a plane. A first openable and closable cover 33 is disposed at a position corresponding to the USB slot 2112 of the speaker end on the side of the waterproof silicone sleeve 30. When the first openable/closable cover 33 is opened, the speaker-end USB slot 2112 may be used; when the first openable cover 33 is closed, the speaker-end USB slot 2112 can be protected from external moisture.
