Description

Technical Field

[0001] This invention relates to the field of headphone structure technology, and in particular to a headphone. Background Technology

[0002] Nowadays, urban workers face increasing life pressures, and negative emotions can easily lead to various physical problems, ranging from loss of appetite and lethargy to more serious conditions such as depression. Therefore, the need for monitoring one's own health indicators is essential.

[0003] Headphones, mobile phones, watches, and other portable electronic devices that are frequently used by ordinary people are important means of monitoring health indicators. Especially for young people who are accustomed to using headphones, being able to monitor their various indicators in real time through headphones and detect health problems early will play a very important role in maintaining health.

[0004] Currently, there is a lack of products on the market that utilize headphones to collect low-frequency heart sounds. This is mainly because heart sounds are in the ultra-low frequency range below 20Hz, and the noise-canceling microphones of existing headphones have poor performance in collecting this frequency band; in addition, there is too much noise in the ear canal, making it difficult to collect. Summary of the Invention

[0005] The main objective of this invention is to propose an earphone that can effectively acquire low-frequency heart sound signals.

[0006] To achieve the above objectives, the present invention provides an earphone, wherein the earphone comprises:

[0007] The outer shell has an ear inlet end with an opening.

[0008] The mounting bracket is installed inside the housing and covers the opening. The mounting bracket has a sound hole and a sound receiving hole corresponding to the opening.

[0009] A speaker, mounted on the side of the mounting bracket facing inwards from the housing, and positioned corresponding to the sound hole; and,

[0010] A microphone is mounted on the side of the mounting bracket facing the inside of the housing, and the microphone's microphone port is connected to the microphone hole on the mounting bracket to receive low-frequency heart sounds transmitted through the hole.

[0011] In one embodiment, the microphone is attached to the mounting bracket such that the microphone's sound port is in communication with the sound receiving hole.

[0012] In one embodiment, the microphone is attached to the mounting bracket by adhesive.

[0013] In one embodiment, the mounting bracket includes a base plate covering the opening and a side panel extending from the edge of the base plate toward the interior of the housing, the side panel being circumferentially arranged along the edge of the base plate, and the sound hole and the sound receiving hole being formed on the base plate.

[0014] In one embodiment, the base plate is mounted to the housing via a resilient seal.

[0015] In one embodiment, the resilient sealant comprises foam adhesive.

[0016] In one embodiment, a gap is provided between the side panel and the outer shell.

[0017] In one embodiment, the side panel supports and fixes the speaker, and the gap between the speaker and the side panel is sealed by a sealing structure, so that the speaker, the base plate and the side panel enclose a cavity, and the sound hole connects the cavity and the opening.

[0018] In one embodiment, the microphone is mounted in the cavity.

[0019] In one embodiment, a pressure detection device is also provided inside the cavity.

[0020] In one embodiment, the detection structure of the air pressure detection device includes a diaphragm within the microphone.

[0021] In one embodiment, the earphone further includes a flexible circuit board, and the microphone and the speaker are electrically connected to the flexible circuit board, respectively.

[0022] In one embodiment, the frequency of the sound signal received by the microphone is A, then A < 20Hz.

[0023] In the technical solution of this invention, the earphone includes a housing and a speaker and a microphone installed within the housing. On one hand, the microphone is configured to receive low-frequency heart sounds. On the other hand, the speaker and microphone are mounted within the housing via a mounting bracket. Compared to directly mounting the speaker and microphone to the housing, the mounting bracket provides a certain degree of isolation, isolating vibrations caused by noise received by the housing, thereby reducing the impact of noise on the microphone's reception of low-frequency heart sounds. This configuration, by optimizing the structure and improving the sound wave propagation path, allows for better collection of heart sound information within the ear canal using the structure in conjunction with the microphone capable of receiving low-frequency heart sounds, thus meeting usage requirements.

[0033] Nowadays, urban workers face increasing life pressures, and negative emotions can easily lead to various physical problems, ranging from loss of appetite and lethargy to more serious conditions such as depression. Therefore, the need for monitoring one's own health indicators is essential.

[0034] Headphones, mobile phones, watches, and other portable electronic devices that are frequently used by ordinary people are important means of monitoring health indicators. Especially for young people who are accustomed to using headphones, being able to monitor their various indicators in real time through headphones and detect health problems early will play a very important role in maintaining health.

[0035] Currently, there is a lack of products on the market that utilize headphones to collect low-frequency heart sounds. This is mainly because heart sounds are in the ultra-low frequency range below 20Hz, and the noise-canceling microphones of existing headphones have poor performance in collecting this frequency band; in addition, there is too much noise in the ear canal, making it difficult to collect.

[0036] This invention proposes an earphone; please refer to [link / reference]. Figures 1 to 2 The following is a detailed description of the headphones as described in this application, with reference to the specific accompanying drawings.

[0037] Please see Figures 1 to 2The earphone 100 includes a housing 1, a mounting bracket 2, a speaker 3, and a microphone 4. The housing 1 has an in-ear end with an opening 11. The mounting bracket 2 is installed inside the housing 1 and covers the opening 11. The mounting bracket 2 has a sound hole 21 and a sound receiving hole 22 corresponding to the opening 11. The speaker 3 is installed on the side of the mounting bracket 2 facing the inside of the housing 1 and is positioned corresponding to the sound hole 21. The microphone 4 is installed on the side of the mounting bracket 2 facing the inside of the housing 1, and the sound receiving port on the microphone 4 is connected to the sound receiving hole 22 on the mounting bracket 2 to receive low-frequency heart sounds transmitted through the opening 11.

[0038] In the technical solution of this invention, the earphone 100 includes a housing 1 and a speaker 3 and a microphone 4 installed within the housing 1. On one hand, the microphone 4 is configured to receive low-frequency heart sounds. On the other hand, the speaker 3 and the microphone 4 are installed within the housing 1 via a mounting bracket 2. Compared to directly installing the speaker 3 and the microphone 4 onto the housing 1, the mounting bracket 2 provides a certain degree of isolation, isolating vibrations caused by noise received by the housing 1, thereby reducing the impact of noise on the microphone 4's reception of low-frequency heart sounds. This configuration, by optimizing the structure and improving the sound wave propagation path, allows for better collection of heart sound information within the ear canal using the structure in conjunction with the microphone 4, which is capable of receiving low-frequency heart sounds, thus meeting usage requirements. Specifically, to meet the requirement of picking up low-frequency heart sounds, the lowest sound frequency that the microphone 4 in this application can pick up should be below 20Hz. It is understood that the microphone 4 in this application is mainly used to pick up low-frequency heart sounds. While achieving the same objective, the microphone 4 can be replaced, for example, by being configured as a pickup unit, depending on actual needs, and is not limited here.

[0039] Specifically, the microphone 4 is attached to the mounting bracket 2 so that the microphone 4's microphone port is connected to the microphone hole 22. The connection between the microphone 4's microphone port and the microphone hole 22 on the mounting bracket 2 can be achieved in various ways, including but not limited to connecting via an additional conduit. However, obviously, an additional conduit increases the possibility of the microphone 4 picking up noise and also increases cost, making it less practical. Therefore, in this embodiment, the microphone 4 is directly attached to the mounting bracket 2 so that the microphone 4's microphone port is directly connected to the microphone hole 22. This eliminates the need for an additional connection structure to connect the microphone 4's microphone port to the microphone hole 22, allowing the microphone port to directly connect to the opening 11 on the outer shell 1. This enables better collection of heartbeat information and reduces noise interference caused by the headphone 100 structure.

[0040] Furthermore, the microphone 4 is adhered to the mounting bracket 2 using adhesive. Based on the structural feature that the microphone 4 is attached to the mounting bracket 2 so that the microphone port directly connects to the microphone hole 22, the microphone 4 can be attached and fixed to the mounting bracket 2 in various ways, such as by screwing it onto the mounting bracket 2, or by welding it directly to the mounting bracket 2, etc. Any method that achieves the aforementioned attachment feature is acceptable and is not limited here. In this embodiment, the microphone 4 is adhered to the mounting bracket 2 using double-sided adhesive. This method is convenient for installation and removal, low in cost, and effective. Furthermore, the adhesive used also provides a certain degree of sealing to seal the gap between the microphone port and the microphone hole 22, ensuring its sound reception performance. Additionally, the adhesive also provides a certain degree of buffering and protection, further cushioning and preventing vibrations of the mounting bracket 2 from affecting the microphone 4's pickup of heart sounds.

[0041] Furthermore, the mounting bracket 2 includes a base plate 23 covering the opening 11 and a side panel 24 extending from the edge of the base plate 23 toward the interior of the outer casing 1. The side panel 24 is arranged around the edge of the base plate 23, and the sound hole 21 and the sound receiving hole 22 are opened on the base plate 23. The mounting bracket 2 mainly includes the base plate 23 located at the opening 11. In this embodiment, the side panel 24 extending toward the interior of the outer casing 1 is also provided along the edge of the base plate 23. The side panel 24 is arranged around the edge of the base plate 23, which increases the installable operating area of ​​the mounting bracket 2, facilitating the installation of various structures inside the outer casing 1, or facilitating the arrangement of the installation positions of the structures inside the outer casing 1, and improving the freedom of structural design. On the other hand, it increases the noise isolation area to improve the isolation of the mounting bracket 2 from noise vibration from the outer casing 1 and meet functional requirements.

[0042] Furthermore, the base plate 23 is mounted to the outer shell 1 via an elastic sealing element 25. On one hand, when the base plate 23 is mounted to the outer shell 1, the connection between the base plate 23 and the outer shell 1 needs to be sealed by the sealing element to ensure the sealing performance of the earphone 100 and extend its service life. On the other hand, the aforementioned sealing element is an elastic sealing element 25, so that the connection between the base plate 23 and the outer shell 1, sealed by the elastic sealing element 25, also has a certain vibration buffering effect, further improving the noise and vibration isolation performance of the mounting bracket 2 and meeting functional requirements. Specifically, in this embodiment, the elastic sealing element 25 is made of foam adhesive, which has a simple structure, low cost, good effect, and is more practical.

[0043] Furthermore, a gap is provided between the side panel 24 and the outer shell 1. This gap is designed to prevent external noise signals from passing through the outer shell 1 of the earphone 100 during vibration propagation. The side panel 24 isolates the vibration, and the spaced arrangement between the side panel 24 and the outer shell 1 avoids direct contact propagation. This maximizes the isolation of the microphone 4 from vibrations on the outer shell 1, effectively shielding the microphone 4 from interference signals and ensuring its reception of low-frequency heart sounds.

[0044] Furthermore, the side panel 24 supports and fixes the speaker 3, and the gap between the speaker 3 and the side panel 24 is sealed by a sealing structure 26, so that the speaker 3, the base plate 23, and the side panel 24 enclose a cavity 27, and the sound hole 21 connects the cavity 27 and the opening 11. With the speaker 3 fixed to the mounting bracket 2, the sealing structure 26, located at the gap between the speaker 3 and the side panel 24, serves two purposes: firstly, to stabilize and seal the speaker 3; and secondly, to form the cavity 27, thereby improving the sound performance of the speaker 3. Specifically, the sealing structure 26 is made of sealing silicone.

[0045] Furthermore, the microphone 4 is installed in the cavity 27. The installation positions of the microphone 4 and the speaker 3 on the mounting bracket 2 are not limited; they can be spaced apart from each other as long as they fulfill their respective functions. In this embodiment, the microphone 4 is placed inside the cavity 27. This reduces the space occupied by the speaker 3 and the microphone 4, and the cavity 27 further shields noise, meeting the high-precision sound pickup requirements of the microphone 4.

[0046] In addition, an air pressure detection device 5 is also provided inside the cavity 27. It is understood that if the earphone 100 is not the right size or is worn incorrectly, it will cause air leakage in the ear canal. This leakage affects sound quality, leading to poorer noise reduction and a worse user experience; it also affects the acquisition of infrasound waves, reducing the accuracy of heart sound signal monitoring. Therefore, after the earphone 100 is worn, it automatically triggers a fit detection. At this time, the speaker 3 continuously plays a preset audio, and its diaphragm vibrates the air to produce sound. Since the ear canal is a sealed structure when the earphone 100 is worn normally, the internal air pressure changes with the audio output of the speaker 3. The air pressure detection device 5, located in the cavity 27, detects these changes in air pressure and determines whether the earphone 100 is worn correctly. This allows the user to be alerted to adjust the earphone if it is worn incorrectly, thus ensuring a better user experience.

[0047] Specifically, the detection structure of the air pressure detection device 5 includes a diaphragm inside the microphone 4. It is understood that the air pressure detection device 5 can be a structure independent of the speaker 3 and the microphone 4, but the microphone 4 contains the diaphragm structure, whose function is similar to that of the air pressure detection device 5. Therefore, in this embodiment, the diaphragm inside the microphone 4 is used as the air pressure detection device 5 to reduce structural costs.

[0048] In addition, the earphone 100 also includes a flexible circuit board 6, and the microphone 4 and the speaker 3 are electrically connected to the flexible circuit board 6 respectively. To facilitate the control of the speaker 3 and the microphone 4 by the earphone 100, the flexible circuit board 6 is also provided inside the earphone 100 for electrical connection with the microphone 4 and the speaker 3. Specifically, the flexible circuit board 6 is easy to adjust in shape and layout, and has practicality.

Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
