Description

Technical Field

[0001] The present invention relates to the technical field of earphones, and in particular to an earphone and an earphone set. Background Art

[0002] As we all know, with the technological development and upgrading of smart electronic products such as mobile phones and tablets, the research and development of their accessories has also been continuously improving. For example, although Bluetooth technology successfully made traditional headphones wireless in the last century, giving birth to wireless Bluetooth headphones, in fact, the market performance of wireless Bluetooth headphones has been lukewarm. It was not until recent years that major manufacturers eliminated the headphone jack of smart electronic products in pursuit of lightweight design, and then wireless Bluetooth headphones really began to be rapidly promoted.

[0003] Compared to traditional headphones, wireless Bluetooth headsets free users from the cumbersome demands of wires, allowing them to make calls in a variety of ways. The speaker inside a wireless Bluetooth headset consists of a diaphragm, voice coil, and magnet. The voice coil is fixed to the diaphragm. When current flows through the voice coil, it generates a magnetic field. The interaction between the magnetic field and the magnet drives the diaphragm to vibrate, producing sound.

[0004] Currently, the internal design of existing wireless Bluetooth headsets places the speaker and battery in close proximity, with the diaphragm facing the headphone outlet and the magnet facing away from the outlet and closer to the battery. This structural design is the easiest to manufacture, and therefore adopted by almost all headphone manufacturers without hesitation. However, this structural design has problems. Due to the close proximity of the magnet and battery, the magnetic field generated by them can easily interfere with the vibration control of the speaker diaphragm, thereby affecting the sound quality of the wireless Bluetooth headset, and also significantly affect the performance of the battery circuit.

[0005] Therefore, improvements to the existing technology are needed. There are two common solutions: 1. Installing the battery inside the earphone stem. However, this approach is difficult to manufacture, places specific demands on the battery, is costly, and is not suitable for earphones without stems (such as bean-shaped and earhook earphones). 2. Positioning the battery as far away from the speaker as possible, i.e., leaving an isolation gap between the battery and the speaker to increase the distance between them. However, this approach increases the overall thickness of the earphones, which does not meet the requirements for miniaturization and lightweighting, and is unacceptable to users.

[0006] Therefore, the existing improvement solutions are too limited and are not suitable for promotion in delicate and beautiful product lines.

[0007] The above information is presented as background information only to assist with an understanding of the present disclosure and is not a determination or admission that any of the above may be applicable as prior art with respect to the present disclosure. Summary of the Invention

[0008] The present invention provides an earphone and an earphone kit to solve the problem in the prior art that the distance between the magnet in the earphone and the battery is too close, thereby affecting the earphone sound quality and the battery circuit performance.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0014] The speaker includes a magnet and a diaphragm, the diaphragm faces the first front cavity, and the magnet is arranged close to a side of the second front cavity away from the battery so that the speaker is disposed facing the battery.

[0015] Furthermore, in the earphone, the front cavity and the rear cavity are separated by a partition plate, and a first tuning hole communicating with the first front cavity is formed on the partition plate;

[0016] A first tuning net is attached to the first tuning hole.

[0017] Furthermore, in the earphone, the speaker is fixed in the shell, and the magnet is arranged in the shell close to the second front cavity.

[0018] Furthermore, in the earphone, a second tuning hole communicating with the second front cavity is provided on the shell at a position corresponding to the second front cavity;

[0019] A second tuning net is attached to the second tuning hole.

[0020] Furthermore, in the earphone, the second front cavity is sealed and separated from the first front cavity, and the second front cavity is connected to the rear cavity.

[0021] Furthermore, in the earphone, the second front cavity is connected to the rear cavity through an assembly gap.

[0022] Furthermore, the earphones also include a charging copper column and an FPC reinforcement plate;

[0023] A charging hole is provided on the shell;

[0024] The FPC reinforcement plate is arranged in the housing;

[0025] The charging copper column is arranged on the FPC reinforcement plate and penetrates the charging hole.

[0026] Furthermore, in the earphone, the FPC reinforcement plate is provided on the inner wall of the shell and extends into the rear cavity along the assembly gap between the second front cavity and the rear cavity.

[0027] In a second aspect, an embodiment of the present invention provides an earphone kit, comprising:

[0028] Earphones, wherein the earphones are the earphones as described in the first aspect above;

[0029] An earphone box, in which the earphone can be stored, is provided with a positioning member that attracts the magnet.

[0030] Furthermore, in the earphone kit, an earphone storage slot is provided in the earphone box;

[0031] The positioning piece is arranged in the earphone receiving slot at a position corresponding to the magnet.

[0032] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0033] An embodiment of the present invention provides an earphone that reversely configures the speaker in the front cavity, that is, the diaphragm in the speaker is arranged on the side opposite to the front cavity and close to the battery, and the magnet in the speaker is arranged on the side away from the battery. This increases the distance between the magnet and the battery, and no longer generates a magnetic field that easily interferes with the signal between the two, thereby avoiding affecting the sound quality of the earphone and the performance of the battery circuit.

[0034] The earphone set provided by the embodiment of the present invention not only has the aforementioned earphones with improved sound quality, but also saves the conventional magnet configuration space and cost because the magnet of the speaker in the earphone is used for adsorption and detection when entering the box.

[0051] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0052] Example 1

[0053] In light of the aforementioned deficiencies in existing wireless Bluetooth headsets, the applicant, drawing upon years of extensive practical experience and expertise in the design and manufacture of such products, combined with applied theory, has actively engaged in research and innovation, hoping to develop a technology that addresses these deficiencies and thereby enhance the practicality of wireless Bluetooth headsets. Through continuous research and design, repeated prototype production, and refinement, the applicant has ultimately developed the present invention, which possesses substantial practical value.

[0054] Please refer to Figure 1-5 , an embodiment of the present invention provides a headset, comprising:

[0055] The housing 1 has a front cavity 4 and a rear cavity 5 separated from each other. The front cavity 4 is provided with a sound outlet 2 connecting the accommodating cavity with the outside world.

[0056] a battery 6, disposed in the rear cavity 5;

[0057] a loudspeaker 7 disposed in the front cavity 4 and dividing the front cavity 4 into a first front cavity 401 and a second front cavity 402 , wherein the first front cavity 401 is in communication with the sound outlet 2 ;

[0058] The speaker 7 includes a magnet 701 and a diaphragm 702 . The diaphragm 702 faces the first front cavity 401 . The magnet 701 is arranged close to the side of the second front cavity 402 away from the battery 6 so that the speaker 7 faces the battery 6 .

[0059] It should be noted that, as mentioned in the background technology, the side of the speaker of the wireless Bluetooth headset in the prior art has a diaphragm facing the headset sound outlet, while the side with the magnet is away from the headset sound outlet and close to the battery. In this structural design, the speaker divides the interior of the shell into a front cavity and a rear cavity, and then the side of the speaker with the diaphragm is located in the front cavity, and the side with the magnet is located in the rear cavity, that is, the front cavity faces outward (close to the human head), and the rear cavity faces inward (close to the outside world). This is a common practice in the industry and is the most convenient structural design for headset production. However, widespread application does not mean that there are no problems. The applicant discovered in production research that this structural design has the problem of affecting the sound quality of the headset and the performance of the battery circuit. The reason is that the distance between the magnet and the battery is too close, so that a magnetic field will be generated between the two, which can easily affect the sound quality of the headset and the performance of the battery circuit. Therefore, in order to solve this problem, the present application still divides the front cavity 4 and the rear cavity 5, and the front cavity faces outward (close to the human head) and the rear cavity faces inward (close to the outside world). However However, the speaker 7 is not used as the dividing line between the front cavity 4 and the rear cavity 5. In fact, this embodiment creatively uses the speaker 7 to further divide the front cavity 4, that is, the front cavity 4 includes a first front cavity 401 and a second front cavity 402 (there is no further division of the front cavity 4 in the prior art), and then the diaphragm 702 in the speaker 7 is set in the first front cavity 401, and the magnet 701 in the speaker 7 is set in the second front cavity 402, that is, relative to the front cavity 4, the second front cavity 402 faces outward (close to the human head side), and the first front cavity 401 faces inward (close to the outside side). In this way, the appearance of the earphones is unchanged, but inside the earphones, the entire speaker 7 is reversed, that is, the original diaphragm is far away from the battery and the magnet is close to the battery. Now the magnet 701 is far away from the battery 6 and the diaphragm 702 is close to the battery 6, which makes it impossible for the magnet 701 and the battery 6 to generate a magnetic field that easily affects the sound quality of the earphones and the performance of the battery circuit due to the increased distance, thereby solving the problem of affecting the sound quality of the earphones and the performance of the battery circuit.

[0060] In addition, although this embodiment further divides the front cavity 4 into a first front cavity 401 and a second front cavity 402, and the speaker is inverted, since the first front cavity 401 is designed to be connected to the sound outlet 2, the sound generated by the vibration of the diaphragm 702 can still be transmitted to the sound outlet 2 through the first front cavity 401 and then enter the ear.

[0061] It can be understood that the shell 1 in this embodiment, in addition to accommodating the components listed above, should also include device designs such as a main board and a microphone board. The specific function of these devices is to ensure the normal operation of the various functions of the headset. Since these device designs have been implemented in many existing technologies and are not the focus of the design of this solution, they will not be elaborated in depth here.

[0062] Similarly, in addition to the magnet 701 and diaphragm 702 listed above, the speaker 7 should also include device designs such as a voice coil and a washer. The specific function of these devices is to ensure the normal operation of the various functions of the earphones. Since these device designs have been widely implemented in the existing technology and are not the focus of the design of this solution, they will not be elaborated in depth here.

[0063] In this embodiment, the speaker 7 is fixed in the housing ( 1 ), and the magnet 701 is arranged in the housing 1 close to the second front cavity 402 .

[0064] In this embodiment, the front cavity 4 and the rear cavity 5 are specifically separated by a partition plate 3, and the partition plate 3 is provided with a first tuning hole 8 communicating with the first front cavity 401;

[0065] A first tuning net 9 is attached to the first tuning hole 8 .

[0066] Optionally, the first tuning net 9 is located in the first front cavity 401 .

[0067] It should be noted that the design of the first tuning hole 8 enables the first front cavity 401 to be connected with the rear cavity 5, thereby achieving the purpose of releasing the pressure in the first front cavity 401 on the one hand, and on the other hand, excluding the airflow formed by the vibration of the diaphragm 702 in the speaker 7 from the first front cavity 401, so as to reduce the impact of the airflow on the output of the sound source and improve the frequency response; and the design of the first tuning net 9 can, on the one hand, prevent dust from entering the first front cavity 401 through the first tuning hole 8, and on the other hand, it can also achieve the purpose of tuning by affecting the sound transmission effect by setting the air permeability (specifically, the number, density, and size of the grids on the first tuning net 9 will affect the air permeability).

[0068] Moreover, the first tuning net 9 can be set to be fixedly set in the first front cavity 401, or can be set to be movably set in the first front cavity 401. There is no restriction here. However, if it is movably set, two or more tuning areas with different air permeabilities need to be designed on the first tuning net 9, so as to improve the tuning effect of the headphones and improve the user experience.

[0069] In this embodiment, a second tuning hole 10 communicating with the second front cavity 402 is opened on the housing 1 at a position corresponding to the second front cavity 402 ;

[0070] A second tuning net 11 is attached to the second tuning hole 10 .

[0071] Optionally, the second tuning net 11 is located in the second front cavity 402 .

[0072] Similarly, the design of the second tuning hole 10 enables the second front cavity 402 to communicate with the outside world, thereby releasing the pressure in the second front cavity 402; and the design purpose of the second tuning net 11 is to prevent dust from entering the second front cavity 402 through the second tuning hole 10.

[0073] In addition, since the second tuning net 11 only needs to cooperate with the second tuning hole 10 to adjust the pressure in the second front cavity 402 and prevent dust from entering, there is no need for the second tuning net 11 to be movable. It is generally sufficient to be fixed in the second front cavity 402. Moreover, there is no restriction on the number, density, and size of the grids on the second tuning net 11, and they can be determined according to the size of the dust particles that need to be blocked.

[0074] In this embodiment, the second front cavity 402 is sealed and separated from the first front cavity 401 , and the second front cavity 402 is connected to the rear cavity 5 .

[0075] Optionally, the second front cavity 402 is connected to the rear cavity 5 through an assembly gap.

[0076] It should be noted that, in this embodiment, the second front cavity 402 is connected to the rear cavity 5 through an assembly gap, which is beneficial for decompressing the gas in the ear canal to the rear cavity 5 and then transmitting it out from the rear cavity 5 when wearing.

[0077] In this embodiment, the earphone further includes a charging copper column 12 and an FPC reinforcement plate 13;

[0078] The housing 1 is provided with a charging hole 14;

[0079] The FPC reinforcement plate 13 is arranged in the housing 1;

[0080] The charging copper column 12 is disposed on the FPC reinforcement plate 13 and passes through the charging hole 14 .

[0081] It should be noted that the design of the charging copper column 12 and the FPC reinforcement plate 13 is to provide the earphone with a rechargeable function, that is, the battery 6 can be charged by contacting the charging contacts of the charging box through the charging copper column 12 and the FPC reinforcement plate 13.

[0082] In this embodiment, the charging hole 14 is provided on the housing 1 at a position corresponding to the second front cavity 402 ;

[0083] The FPC reinforcement plate 13 is disposed in the second front cavity 402 .

[0084] It should be noted that since the second front cavity 402 accommodates the magnet 701 instead of the diaphragm 702, a charging hole 14 can be opened at the position corresponding to the second front cavity 402 on the shell 1, and then the FPC reinforcement plate 13 can be set in the second front cavity 402, which will not affect the sound quality of the earphones.

[0085] Moreover, since the second front cavity 402 is facing outward (close to the side of the human head), when the earphone storage slot of the matching earphone box is opened horizontally, that is, the earphone is placed flat in the earphone storage slot, the charging copper column 12 located on the shell 1 corresponding to the second front cavity 402 is a design that facilitates charging, because the position on the shell 1 corresponding to the second front cavity 402 is just facing the bottom of the earphone storage slot, which makes it convenient to contact with the charging contacts designed on the bottom of the earphone storage slot, and the contact is relatively stable.

[0086] In this embodiment, the FPC reinforcement plate 13 is disposed on the inner wall of the housing 1 and extends into the rear cavity 5 along the assembly gap between the second front cavity 402 and the rear cavity 5 .

[0087] It should be noted that the assembly gap here is not the same as the aforementioned assembly gap. The assembly gap here is generally fixed in the shell and extends to connect to the control board.

[0088] Optionally, the FPC reinforcement plate 13 can be fixed in the housing 1 by means of 3M adhesive bonding and hot gluing.

[0089] Although terms such as housing, sound outlet, partition, first cavity, second cavity, battery, and speaker are frequently used herein, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations would be contrary to the spirit of the present invention.

[0090] An embodiment of the present invention provides an earphone that reversely configures the speaker in the front cavity, that is, the diaphragm in the speaker is arranged on the side opposite to the front cavity and close to the battery, and the magnet in the speaker is arranged on the side away from the battery. This increases the distance between the magnet and the battery, and no longer generates a magnetic field that easily interferes with the signal between the two, thereby avoiding affecting the sound quality of the earphone and the performance of the battery circuit.

[0091] Example 2

[0092] Please refer to Figure 6 , an embodiment of the present invention provides an earphone kit, comprising:

[0093] Earphones, wherein the earphones are the earphones as described in the first embodiment;

[0094] An earphone box, in which the earphones can be stored, is provided with a positioning member 15 that attracts the magnet 701 .

[0095] Optionally, an earphone storage slot 16 is provided in the earphone box;

[0096] The positioning member 15 is provided in the earphone receiving slot 16 at a position corresponding to the magnet 701 .

[0097] It should be noted that in the prior art, when a wireless Bluetooth headset is placed in a charging box, no matter whether the headset receiving slot 16 is opened vertically or horizontally, the common positioning method for the headset is generally to rely on one or more magnets (or iron blocks) added to the headset, and then cooperate with the iron blocks (or magnets) set at corresponding positions in the headset receiving slot 16, and use the principle of opposite magnets attracting each other or attracting each other with the iron blocks to make the headset and the charging box positioned in the same way, so that the charging copper column 12 can accurately contact the charging pin 17 set in the headset receiving slot 16, thereby realizing the function of accurately storing and charging the headset. The specific design diagram is as follows Figure 7-8 As shown, Figure 7 The example shown is an example of a headphone receiving slot 16 being opened horizontally. Figure 8 What is shown is an example of a vertically opened earphone receiving slot 16. Since the prior art requires adding materials such as iron blocks or magnets to both the earphones and the charging box, it not only increases the production cost, but also increases the instability of the structure, while also taking up valuable space inside the earphones. Unlike the prior art, this embodiment only needs to add a positioning member 15 in the charging box, which can be an iron block or a magnet, and then use the magnet 701 of the speaker 7 in the earphone itself to attract and position it with the positioning member 15. This is the effect of the inverted design of the speaker 7 in this embodiment, because the magnet 701 in the speaker 7 is set in the second front cavity 402 facing outward (close to the side of the human head), so it is closer to the earphone receiving slot 16, so that the magnet 701 can directly generate a mutual attraction force with the positioning member 15 set at the corresponding position in the earphone receiving slot 16 to help position the earphone.

[0098] An embodiment of the present invention provides an earphone set that, in addition to having the aforementioned earphones with improved sound quality, also uses the magnet of the speaker in the earphones for adsorption and detection when entering the box, thereby saving the space and cost of conventional magnet configuration.
