Description

Technical Field

[0001] The present invention relates to the field of speaker technology, and in particular to a method for quickly mute control of speaker equipment. Background Art

[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it means that the speaker mainframe or subwoofer has a built-in power amplifier, which amplifies the audio signal and then plays it back by the speaker itself, making the sound louder. The speaker is the terminal of the entire sound system, and its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the sound system, responsible for converting electrical signals into sound signals for direct human hearing.

[0003] In actual use, sometimes the speaker device needs to quickly mute the speaker that is playing audio. The existing practice is: generally, it is necessary to mute the device through a separate "mute" button, or to mute the device by adjusting the volume to 0 through the "volume knob" or "volume minus" key. There are some problems that need to be overcome in these traditional mute operations: 1. The solution of a separate mute button requires a special "mute" button to be reserved for the device, which not only occupies the surface area of ​​the small speaker, but also increases the difficulty of designing the appearance and structure; 2. The volume is adjusted through the "volume knob" or "volume minus" to achieve muting, and the adjustment process is slow, and the "quick" mute effect cannot be achieved.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0005] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a method for quickly muting a speaker device. By covering a designated area of ​​the device with the palm of the hand, the device can be quickly muted, which does not affect the appearance and structural design and can achieve quick silencing.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A method for quickly mute control of a speaker device is disclosed. Four buttons are reserved on a panel of the speaker, namely, a volume-button, a volume+button, a call button, and a microphone button, and the four buttons are all capacitive touch buttons. When a user covers the four buttons on the panel with his palm, the speaker automatically controls to quickly mute.

[0008] As a preferred solution, among the four buttons, if one of them is triggered individually, the software of the control system of the speaker recognizes the key value of the button; if more than two buttons are passively triggered at the same time, the key value recognized by the software is the combined value of the two or more buttons; the control system of the speaker mutes the speaker according to the combined value of the four buttons recognized by the software.

[0009] As a preferred solution, the key acquisition module collects the four keys respectively, and the corresponding bit of the key storage register corresponding to the triggered key will be set to 1, and the corresponding bit of the register corresponding to the untriggered key will be set to 0; when a key is triggered, the key acquisition module will send an interrupt signal to notify the key distribution module to distribute the key;

[0010] After receiving the interrupt signal, the key distribution module reads the key register stored in the key acquisition module, and the register value is decoded by the key decoding module to obtain the key value.

[0011] As a preferred solution, the key distribution module divides the key events into single key events and combined key events based on the decoding results fed back by the key decoding module. After obtaining the key event type, it is necessary to determine whether it is a palm-covering action. The determination conditions are: first, the key event is a combined key event, and second, the key value is a set value. When both conditions are met, it is determined to be a palm-covering action, and the speaker is muted at this time.

[0012] As a preferred solution, the speaker includes

[0013] The bottom of the face shell has a speaker mounting position, a circuit board mounting position and a battery mounting position, and the top of the face shell is provided with a sound outlet corresponding to the speaker mounting position;

[0014] The speaker electronic functional component includes a PCBA board, a speaker and a battery; the speaker is installed in the speaker installation position, the battery is installed in the battery installation position, the PCBA board is installed in the circuit board installation position, and the PCBA board is located below the speaker and the battery is located beside the speaker;

[0015] Bottom shell; the bottom shell is detachably assembled on the bottom of the surface shell to cover the electronic functional components of the speaker.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that it mainly associates multiple buttons to be triggered simultaneously to automatically control the quick muting of the speaker. By covering the designated area of ​​the device with the palm, the device can be muted quickly, which does not affect the appearance and structural design and can achieve quick muting. Compared with small devices with independent mute button solutions, the present invention deletes a mute button, which is convenient for ID, structure, and circuit design, and reduces development cycle and design cost. Compared with the solution of achieving muting by operating the knob and volume reduction button, the present invention can achieve the purpose of muting more quickly.

DETAILED DESCRIPTION

[0034] Please refer to Figures 1 to 15 As shown, it shows the specific scheme of the embodiment of the present invention.

[0035] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] A method for quickly mute control of a speaker device is disclosed. Four buttons are reserved on a panel of the speaker, namely, a volume-button, a volume+button, a call button, and a microphone button, and the four buttons are all capacitive touch buttons. When a user covers the four buttons on the panel with his palm, the speaker automatically controls to quickly mute.

[0037] Among the four buttons, if one button is triggered individually, the software of the control system of the speaker recognizes the key value of the button. If more than two buttons are passively triggered at the same time, the key value recognized by the software is the combined value of the two or more buttons. The control system of the speaker mutes the speaker according to the combined value of the four buttons recognized by the software. When each touch button is triggered individually, the software recognizes the key values ​​as 0x01, 0x02, 0x04, and 0x08 respectively. All buttons can be triggered at the same time, and the key value recognized after triggering is the combined value. Figure 4 As shown:

[0038] [Volume-] and [Call] are triggered at the same time, and the key value is 0x01|0x02=0x03;

[0039] The [Volume-], [Call], and [Volume+] keys are triggered at the same time, and the key value is 0x01|0x02|0x04=0x07; the [Volume-], [Call], [Volume+], and [Microphone] keys are triggered at the same time, and the key value is 0x01|0x02|0x04|0x08=0x0F;

[0040] When your palm covers the panel, that is, the four touch buttons are triggered at the same time, the software recognizes it as a palm-covering operation and mutes the speaker, achieving the purpose of quick muting.

[0041] The four buttons can be triggered individually or simultaneously; the button acquisition module (such as Figure 1 As shown in the figure, the four buttons (such as buttons K1 to K4) are collected respectively, and the corresponding bit of the button storage register corresponding to the triggered button will be set to 1, and the corresponding bit of the register corresponding to the untriggered button will be set to 0; when a button is triggered, the button collection module will send an interrupt signal to notify the button distribution (such as Figure 2 Module (shown) for distributing the keys;

[0042] After receiving the interrupt signal that the key is triggered, the key distribution module reads the key register stored in the key acquisition module, and the read value is the register value, which is then decoded by the key decoding module (such as Figure 3 The key value is obtained by decoding it.

[0043] The key distribution module divides the key events into single key events and combined key events based on the decoding results fed back by the key decoding module. After obtaining the key event type, it is necessary to determine whether it is a palm-covering action. The determination conditions are: first, the key event is a combined key event, and second, the key value is a set value (for example, the key value is 0x0F). When both conditions are met, it is determined to be a palm-covering action, and the speaker is muted at this time.

[0044] like Figures 9 to 15As shown, it provides an assembly structure of a speaker without a mute button, which subverts the traditional assembly method (the traditional assembly method is generally from bottom to top, that is, the bottom shell is used as the installation reference, the speaker, circuit board and other electronic functional parts are installed on the bottom shell, and then the front shell is installed. This assembly method requires the bottom shell to provide a complex installation and positioning structure for the electronic functional part, especially the tail end of the speaker. The structure of the bottom shell is relatively complex, and it needs to be assisted by gluing and other bonding and positioning at multiple locations during installation, and there are many assembly processes. When subsequent inspection and maintenance are required, it is necessary to remove the front shell, and then remove the electronic functional part. Since the circuit board is located below the speaker, it is more troublesome to disassemble. In fact, common faults of speakers are poor interfaces and local connections on the circuit board. In addition, when the speaker is in use, the bottom shell is often hit, and the electronic functional parts such as the circuit board are installed on the bottom shell, which are easily damaged by vibration.)

[0045] In this embodiment, a speaker without a mute button includes a front shell 10, a speaker electronic functional component 20 and a bottom shell 30. It can be used as a desktop speaker and is suitable for miniaturized design.

[0046] The bottom of the face shell 10 has a speaker mounting position 11, a circuit board mounting position 12 and a battery mounting position 13, and the top of the face shell 10 is provided with a sound outlet hole corresponding to the speaker mounting position 11; here, the corresponding speaker mounting position 11 is a through hole, and further a dust cover with a plurality of dense holes is added on the top of the face shell 10, which can be a dust cover of a thin metal sheet or a plastic sheet, or a dust cloth can be added on the surface of the dust cover. Four buttons are reserved on the top of the face shell 10, namely, the volume-button, the volume+button, the call button and the microphone button, and the four buttons are all capacitive touch buttons; the four buttons act as mute control buttons when triggered together. By triggering multiple buttons at the same time to automatically control the quick muting of the associated speakers, the device can be muted quickly by covering the designated area of ​​the device with the palm of the hand, which does not affect the appearance and structural design and can achieve quick muting. Compared with small devices with independent mute button solutions, the present invention deletes a mute button, which is convenient for ID, structure, and circuit design, and reduces development cycle and design cost. Compared with the solution of achieving muting by operating the knob or volume down button, the present invention can achieve the purpose of muting more quickly.

[0047] The electronic functional component 20 of the speaker includes a PCBA board, a speaker 21 and a battery; a control system is arranged on the PCBA board, and the control system includes a control chip, and a software program can be recorded in the control chip. The control system includes a key acquisition module, a key distribution module, and a key decoding module. The speaker 21 and the battery are connected to the PCBA board through pluggable data interfaces respectively. The speaker is installed at the speaker installation position 11 with the bottom of the face shell 10 as a reference, and the battery is installed at the battery installation position 13 with the bottom of the face shell 10 as a reference, and the PCBA board is installed at the circuit board installation position 12 with the bottom of the face shell 10 as a reference, and the PCBA board is located below the speaker 21, and the battery is located on both sides of the speaker 21; the bottom of the speaker 21 (also referred to as the tail end) keeps a distance from the PCBA board and is not in direct contact; the PCBA board includes a main PCBA board 22 and a battery electrically connected to the speaker 21. The power supply and data input control PCBA board 23 and the button control PCBA board 24 of the main PCBA board 22 are located below the power supply and data input control PCBA board 23 and the button control PCBA board 24; the inner periphery of the face shell 10 is provided with a plurality of card slots 101 arranged at intervals, the PCBA board is connected with a wire, and a plurality of card blocks 27 arranged at intervals are provided on the wire, and the card blocks 27 can be detachably inserted into the corresponding card slots 101, so that the wire is installed and positioned along the inner periphery of the face shell 10. The wires include a first wire 25 and a second wire 26, wherein the first wire 25 is located on a half ring side of the inner periphery of the face shell 10, and the second wire 26 is located on the other half ring side of the inner periphery of the face shell 10; one end of the first wire 25 is connected to the power and data input control PCBA board 23, and the other end of the first wire 25 is connected to the main PCBA board 22 through a pluggable data interface, one end of the second wire 26 is connected to the key control PCBA board 24, and the other end of the second wire 26 is connected to the main PCBA board 22. The data interface is located at the bottom of the main PCBA board 22 and can be exposed by removing the bottom shell 30. A number of connecting columns extend downward from the bottom of the face shell 10, and the main PCBA board 22, the power and data input control PCBA board 23, and the key control PCBA board 24 are respectively connected and positioned at the bottom ends of the corresponding connecting columns. The screws are inserted from the bottom of the main PCBA board 22, the power and data input control PCBA board 23, and the key control PCBA board 24. When installing, the bottom of the cover 10 is turned upside down, and the electronic functional parts are placed and locked in place one by one. When disassembling, it is convenient to remove the screws. The main PCBA board 22, the power and data input control PCBA board 23, and the key control PCBA board 24 all maintain a shock-absorbing gap 40 with the bottom cover 30.

[0048] The bottom shell 30 is detachably assembled at the bottom of the face shell 10 to cover the speaker electronic functional components 20. The top of the bottom shell 30 further extends upward with a plurality of abutment columns 31, which pass through the shock-absorbing gap 40, and the top of the abutment column 31 abuts against the bottom of the corresponding main PCBA board 22, the power and data input control PCBA board 23, and the key control PCBA board 24. The top of the abutment column 31 is a buffer, such as a soft elastic material (silicone sheet, EVA sheet, other shock-absorbing pads, etc.). A foot pad 32 is provided at the bottom of the bottom shell 30, and a foot pad installation recess is usually provided at the bottom of the bottom shell 30, and the foot pad 32 is pasted in the foot pad installation recess. The foot pad 32 can be made of materials such as silicone to play an anti-slip role. At the same time, the foot pad can also reduce the vibration of the bottom shell 30 when it is collided.

[0049] Usually, during installation, the bottom of the face shell 10 is turned upside down, and then the corresponding electronic functional parts are installed one by one. After they are installed in place, they are screwed in and fixed. During operation, it is also equivalent to screwing in from top to bottom. The entire speaker electronic functional component 20 is fixed on the face shell 10 to form a semi-finished product, and then the bottom shell 30 is assembled on the bottom of the face shell 10. When maintenance is required, the bottom shell 30 can be removed. If only the PCBA board is to be repaired, after the bottom shell 30 is removed, it is exposed, and the interface can also be repaired. If further maintenance is required, the main PCBA board 22 and the power supply and data input control PCBA board 23 electrically connected to the main PCBA board 22, the key control PCBA board 24, and even the speaker, etc. are removed by unscrewing the screws. The operation is very simple and fast.

[0050] In this way, the traditional assembly method is overturned, and the speaker electronic functional component 20 is installed based on the front shell 10, so that the bottom shell 30 is not necessarily related to the speaker electronic functional component 20, the structure and assembly process are simpler, and the bottom shell 30 can be disassembled for subsequent maintenance, and it is also convenient to design and control the gap between the speaker electronic functional component 20 and the bottom shell 30. Moreover, it is more conducive to the independent and free design of different shapes of the bottom shell.

[0051] The design focus of the present invention is that multiple buttons are triggered simultaneously to automatically control the rapid muting of the associated speakers. The device can be muted quickly by covering the designated area of ​​the device with the palm of the hand. This does not affect the appearance and structural design, and can achieve rapid muting. Compared with small devices with independent mute key solutions, the present invention deletes a mute button, which is convenient for ID, structure, and circuit design, and reduces development cycle and design cost. Compared with the solution of achieving muting by operating a knob or volume down key, the present invention can achieve the purpose of muting more quickly.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
