[0033] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0036] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0037] The utility model provides a dust-removing earphone and an earphone assembly, which are suitable for application scenarios such as listening to music and can effectively solve the problem that foreign matter at the dustproof net is difficult to clean.

[0038] Example 1

[0039] The earphone assembly provided in this embodiment includes an earphone box and a dust-removing earphone housed in the earphone box.

[0040] See also Figure 1 The dust-removing earphone includes an earphone housing 1, a dust-proof net 2, a first sound wave generator 3, and a second sound wave generator 4.

[0041] The earphone housing 1 is provided with a receiving cavity 101 and a sound outlet hole 102 connecting the receiving cavity 101 to the external space of the earphone housing 1 ; the dustproof net 2 is installed at the sound outlet hole 102 .

[0042] The first sound wave generator 3 and the second sound wave generator 4 are both located in the accommodating cavity 101, the first sound wave generator 3 is arranged opposite to the dustproof net 2, and the operating frequency of the second sound wave generator 4 is lower than that of the first sound wave generator 3, so the vibration energy of the sound wave generated by the first sound wave generator 3 is relatively large, so as to send high-energy sound waves to the dustproof net 2 to shake off foreign objects on the dustproof net 2.

[0043] In this embodiment, the first sound wave generator 3 is a high-frequency speaker; the second sound wave generator 4 includes a medium-frequency speaker and / or a low-frequency speaker. When dust removal is not performed, the first sound wave generator 3 and the second sound wave generator 4 work together to play songs. The first sound wave generator 3 focuses on reinforcing high-frequency segments, and the second sound wave generator 4 focuses on reinforcing medium-frequency and / or low-frequency segments, which is beneficial to improving sound quality.

[0044] When foreign matter such as dust is stuck on the dustproof net 2, the first sound wave generator 3 generates high-frequency sound waves toward the dustproof net 2. The high-frequency sound wave vibration can shake off the foreign matter on the dustproof net 2, thereby cleaning the foreign matter on the dustproof net 2.

[0045] Therefore, the dust-removing earphone and earphone assembly provided by the present invention can effectively solve the problem that foreign matter on the dustproof net 2 is difficult to clean.

[0046] In this embodiment, a battery 6 electrically connected to the first sound wave generator 3 and the second sound wave generator 4 respectively and a circuit board 5 electrically connected to the first sound wave generator 3 and the second sound wave generator 4 respectively are provided in the accommodating cavity 101 .

[0047] Furthermore, the circuit board 5 is provided with a high-frequency sound wave circuit for driving the first sound wave generator 3 to emit high-frequency sound waves and a wireless communication module for wirelessly connecting to a control terminal such as a mobile phone.

[0048] The first sound wave generator 3 is wirelessly connected to a control terminal for controlling the working state of the first sound wave generator 3 through the wireless communication module. The user can control the first sound wave generator 3 to enter the dust removal mode through the control terminal, and then the high-frequency sound wave circuit can drive the first sound wave generator 3 to emit high-frequency sound waves to shake off foreign objects on the dustproof net 2.

[0049] Optionally, a sensor device 7 is further provided in the accommodating cavity 101 , which is arranged opposite to the dustproof net 2 and detects foreign matter on the dustproof net 2 , and the circuit board 5 includes a dust detection circuit electrically connected to the sensor device 7 .

[0050] When there is foreign matter on the dustproof net 2, the sensor device 7 will generate an electrical signal change. After the dust detection circuit detects the changed electrical signal, it automatically controls the high-frequency sound wave circuit to drive the first sound wave generator 3 to emit high-frequency sound waves to automatically shake off the foreign matter on the dustproof net 2.

[0051] Optionally, the sensor device 7 can be a photodetector, and accordingly, the dust detection circuit is a laser dust detection circuit containing an LED. When dust particles in the air enter the sensor cavity, they scatter the light emitted by the LED. The change in the intensity of the light signal received by the photodetector is proportional to the number and size of the dust particles. The signal processing circuit processes these signals, and the microcontroller calculates the concentration of the dust particles based on the processed data. Specifically, the specific structure and working principle of the laser dust detection circuit are not the focus of the present invention and are not described in detail.

[0052] In some other embodiments, the sensor device 7 may also be a capacitor, and accordingly, the dust detection circuit is a capacitive dust detection circuit. The capacitive dust detection circuit detects dust using the principle of dust particle sensitivity to capacitance. When dust particles are deposited on the electrodes of the capacitor, the capacitance value of the capacitor changes. The advantage of this method is that it is also sensitive to atmospheric dust particles with smaller particle sizes.

[0053] Alternatively, the sensor element 7 may also be a thin film resistor, and accordingly, the dust detection circuit is a capacitive dust detection circuit. A resistive dust detection circuit generally uses a thin film resistor, and when dust particles are deposited on the resistor, the resistance value increases.

[0054] In summary, the dust removal earphone and earphone assembly provided in this embodiment have the following beneficial effects:

[0055] ① The first sound wave generator 3 is set directly opposite to the dustproof net 2. When the dustproof net 2 is stuck with dust or other foreign matter, the first sound wave generator 3 emits high-frequency sound waves to shake off the foreign matter on the dustproof net 2. This is simple and convenient, and will not damage the dustproof net 2.

[0056] ② The first sound wave generator 3 is a high-frequency speaker, which is used to emit high-frequency sound waves to remove dust when necessary, and can also be used to cooperate with the second sound wave generator 4 to play sound and improve the sound quality;

[0057] ③Dust removal can be manually controlled through the control terminal, or automatic dust removal can be achieved through the dust detection circuit.

[0058] Example 2

[0059] This embodiment provides a dust removal earphone, which is applicable to the earphone assembly of embodiment 1. The difference between this embodiment and embodiment 1 is that:

[0060] In this embodiment, the first sound wave generator 3 is an ultrasonic oscillator; the second sound wave generator 4 includes at least one of a high-frequency speaker, a medium-frequency speaker, and a low-frequency speaker.

[0061] When dust removal is not performed, the first sound wave generator 3 does not work, and only the second sound wave generator 4 works and plays the song.

[0062] When foreign matter such as dust is stuck on the dustproof net 2, the first sound wave generator 3 generates ultrasonic waves toward the dustproof net 2. The ultrasonic vibration can shake off the foreign matter on the dustproof net 2, thereby cleaning the foreign matter on the dustproof net 2.

[0063] Compared with Example 1, the dust-removing earphones provided by the utility model have the following advantages: the sound wave energy generated by the ultrasonic oscillator when vibrating is greater, and the cleaning effect on foreign matter is better.

[0064] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0065] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
