Description

Technical Field

[0001] This utility model relates to a sound-generating device, and more particularly to headphones. Background Technology

[0002] Earphones (or headphone jacks) are audio devices that convert electrical signals into sound waves. Through speakers or vibrating units placed close to the ears, they convert the electrical signals from audio devices (such as mobile phones, computers, and media players) into audible sound. Their core function is to provide a personalized audio experience while isolating external noise or maintaining environmental awareness, making them suitable for music, calls, work, exercise, and other scenarios. Based on different wearing methods, headphones can be broadly categorized into over-ear, in-ear, earbud, and ear-hook headphones. Ear-hook headphones are designed to fit around the ear. To offer more features, ear-hook headphones often integrate blood oxygen and heart rate monitoring units, allowing users to monitor their physical condition at all times.

[0003] However, due to the differences in ear shape and size among individuals, the distance between the sensing component and the back of the ear is uncontrollable when different people wear the headphones. There is a phenomenon where the distance between the sensing component and the back of the ear exceeds the effective sensing distance of the sensing component, which ultimately leads to the inability to collect blood oxygen and heart rate data, or inaccurate data collection results. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to propose an earphone to solve the problems in the prior art where the distance between the earphone's collection component and the back of the ear is too large, resulting in the inability to collect blood oxygen and heart rate or inaccurate collection results.

[0005] The technical solution adopted by this utility model to solve its technical problem is an earphone, which is suspended from the auricle. The earphone includes:

[0006] The ear frame includes an ear hook and a first connecting part and a second connecting part respectively connected to both ends of the ear hook. A sound-generating element for emitting sound is provided in the first connecting part; and a monitoring element for monitoring heart rate and / or blood oxygen is provided in the second connecting part.

[0009] This utility model has at least the following beneficial effects:

[0010] Using the support section and sound-generating element as a reference, the position of the monitoring element at the second connection part is determined.

[0049] Example 1

[0050] Please refer to Figures 1-2 This utility model discloses an earphone with a suspension portion that hangs on the auricle. The earphone includes an ear frame 100, which includes an ear hook portion 130 and a first connecting portion 110 and a second connecting portion 120 respectively connected to both ends of the ear hook portion 130. A sound-generating element 300 for emitting sound is provided in the first connecting portion 110; a monitoring element 200 for monitoring heart rate and / or blood oxygen is provided in the second connecting portion 120. The ear hook portion 130 has a support section 131, and any point on the support section 131 can be used as the highest support point and abut against the highest point of the suspension portion. The line connecting any highest support point to the center of the sound-generating element 300 is defined as the first connecting line 134, and the line connecting the center of the sound-generating element 300 to the center of the monitoring element 200 is defined as the second connecting line 310. The included angle between the first connecting line 134 and the second connecting line 310 is between 114.6° and 135.7°. The suspension part refers to the recessed area between the ear and the brain. This area has a highest point with the greatest height, and the support of this highest point for the earphone suspended on it is greater than the support of other parts of the suspension part for the earphone.

[0051] First, it should be noted that the earphone in this embodiment is an ear-hook type, suspended above the suspension part of the auricle by the ear hook 130. The first connecting part 110 and the second connecting part 120 are positioned in a clamping posture on the front and back sides of the auricle, respectively, to provide a slight clamping effect. During wearing, the earphone is first hung on the auricle, and then rotated to a predetermined angle, at which point the sound-emitting element 300 is precisely aligned with the ear canal. The design purpose of this invention is that when the earphone is rotated to align the sound-emitting element 300 with the ear canal, the ear bracket 100 can be stably suspended on the auricle. More importantly, it allows the monitoring element 200 to be placed against or as close as possible to the back of the ear, ensuring that the effective monitoring range of the monitoring element 200 can at least partially cover the back of the ear, making the monitoring process smoother and the monitoring results more accurate.

[0052] When the earphone is suspended on the ear, there is a point on the inner surface of the ear hook 130 that abuts against the highest point of the suspension. This point on the inner surface of the ear hook 130 can be defined as the highest support point. It is understandable that, due to differences in ear shape and size among different wearers, after rotating the earphone to align the sound-generating element 300 with the ear canal, the highest support point for each wearer will also be different. These multiple highest support points are continuously distributed on the inner surface of the ear hook 130, forming a continuous segment, which is the support segment 131.

[0053] Based on this, this embodiment uses the support segment 131 and the sound-generating element 300 as a reference to determine the position of the monitoring element 200 in the second connecting part 120 (to ensure that the shape of the ear bracket 100 can adapt to the shape of the auricle, the approximate positions of the first connecting part 110, the ear hook part 130, and the second connecting part 120 are basically fixed, so it is only necessary to determine the position of the monitoring element 200 in the second connecting part 120 to locate the position of the monitoring element 200 in the entire earphone). This ensures that when each highest support point on the support segment 131 contacts the highest point on the auricle, the monitoring element 200 can be as close as possible to or against the back of the ear, so that at least a portion of the back of the ear is within the effective monitoring range covered by the monitoring element 200. Ultimately, while ensuring accurate monitoring of blood oxygen and heart rate, the earphone can be worn on more ears of different shapes and sizes, making it suitable for a wider range of people. That is, the angle between the first connecting line 134 and the second connecting line 310 is between 114.6° and 135.7°.

[0054] It should also be mentioned that the sound-emitting element 300 refers to a device capable of emitting sound, specifically it can be a speaker or other sound-emitting component. The center of the sound-emitting element 300 described in this case is the geometric center of the speaker. Since the purpose of this embodiment is to determine the height position of the monitoring element 200 on the second connecting part 120, if the sound-emitting element 300 has multiple speakers, the center of the sound-emitting element 300 refers to the midpoint between the highest and lowest speakers. The center of the monitoring element 200 refers to the geometric center of the monitoring area formed by several transmitting lights and several receiving lights. Since the purpose of this embodiment is to determine the height position of the monitoring element 200 on the second connecting part 120, the center of the monitoring element 200 can also be understood as the position at half the height of the monitoring area, that is, the center in the height direction.

[0055] It should also be mentioned that monitoring element 200 refers to a device capable of collecting data such as heart rate and blood oxygenation. Specifically, it can be configured as a heart rate and blood oxygenation sensor or other device capable of collecting these two data points. A heart rate and blood oxygenation sensor is a physiological parameter monitoring device based on non-invasive detection technology. It directly reads and transmits health parameters such as blood oxygenation and heart rate to the device through a sensor, realizing real-time monitoring of human health status. Its structure mainly includes a light emitter, a light receiver, and a signal processor. Based on the absorption, reflection, and scattering characteristics of light by human tissue, when a light beam shines on the skin surface, some light is absorbed and some is reflected back. With the heartbeat, the blood volume and blood flow velocity in the blood vessels change periodically, which causes changes in the intensity of light absorption and reflection. By detecting changes in the intensity of reflected or transmitted light, a signal related to cardiac activity, namely the PPG signal, can be obtained. After a series of processing steps on the PPG signal, the heart rate can be calculated. Blood oxygen saturation refers to the percentage of oxyhemoglobin in the blood relative to total hemoglobin. Human tissues exhibit different absorption characteristics to light of different wavelengths. Oxyhemoglobin and deoxyhemoglobin have different absorption coefficients for red and infrared light. The dual-wavelength light absorption ratio algorithm utilizes this characteristic, calculating the light absorption ratio by detecting the light absorption intensity of the PPG signal under red and infrared light, and thus obtaining blood oxygen saturation.

[0056] Furthermore, the end of the support segment 131 near the first connecting part 110 has a first extreme support point 132, and the end of the support segment 131 near the second connecting part 120 has a second extreme support point 133. The angle between the first connecting line 134 where the first extreme support point 132 is located and the first connecting line 134 where the second extreme support point 133 is located is 21°.

[0057] Specifically, the area projected onto the ear hook 130 by the angle formed by the two first lines 134 connecting the first and second extreme support points 132 and 133 is the support segment 131. Determining the size and orientation of this angle determines the position and length of the support segment 131. Setting this angle to 21° maximizes the length of the support segment 131, ensuring it has more maximum support points and a wider range of applicability. Of course, the position and length of the support segment 131 within the ear hook 130 depend on factors such as the headphone's center of gravity, shape, and the curvature design of the ear hook 130.

[0058] Furthermore, when the length direction of the first connecting part is perpendicular to the horizontal plane, the projected length of the first connecting line in the vertical plane is between 19.1mm and 22.7mm.

[0059] Specifically, the height of the first extreme support point 132 is lower than the height of the second extreme support point 133. Since the height difference between the first extreme support point 132 and the center of the sound-generating element 300 is 19.1 mm, and the height difference between the second extreme support point 133 and the center of the sound-generating element 300 is 22.7 mm, this means the height difference between the first extreme support point 132 and the second extreme support point 133 is 22.7 - 19.1 = 3.6 mm. When different people wear the headphones, the highest support point at the upper end of the first connection line can fluctuate within a height difference of 3.6 mm. This height difference allows more earlobes of different sizes and shapes to find a highest support point between the first extreme support point 132 and the second extreme support point 133, thus ensuring stable wearing of the headphones and placing the monitoring element 200 against or as close as possible to the back of the ear.

[0060] In other words, the sound-generating element 300 needs to be aligned with the ear canal, and the height difference between the sound-generating element 300 and the highest support point can be converted into the height difference between the ear canal and the highest point of the suspension. That is to say, as long as the height difference between the wearer's ear canal and the highest point of the suspension is between 19.1mm and 22.7mm, a highest support point can be found within the support section 131 to stably wear the headphones and ensure that at least part of the area behind the ear falls within the coverage area of ​​the monitoring element 200.

[0061] Furthermore, when the length direction of the first connecting part 110 is perpendicular to the horizontal plane, the angle between any first connecting line 134 and the horizontal plane is between 55° and 76°.

[0062] It should be noted that when wearing the headphones, you need to rotate them at a certain angle to get them to the most stable and comfortable position. During the rotation of the headphones, the first connecting wire 134 also rotates, and its angle with the horizontal plane changes accordingly.

[0063] Therefore, if a horizontal plane is used as a reference, the static state of the headphones needs to be selected to describe the first connection 134. In this embodiment, as... Figure 1 As shown, in this static state, the length direction of the first connecting part 110 is perpendicular to the horizontal plane. At this time, the angle between the first connecting line 134 where the first extreme support point 132 is located and the horizontal plane is 55°, and the angle between the first connecting line 134 where the second extreme support point 133 is located and the horizontal plane is 76°. That is, the angle between any first connecting line 134 and the horizontal plane is between 55° and 76°.

[0064] Further, please refer to Figure 3 The monitoring element 200 has a first transmitting area 210, a second transmitting area 220, a first receiving area 230 and a second receiving area 240, and both the first receiving area 230 and the second receiving area 240 can receive light beams from the first transmitting area 210 and the second transmitting area 220.

[0065] The minimum distance between the center of the first launch area 210 and the center of the first receiving area 230 is between 4.5mm and 9mm;

[0066] And / or, the minimum distance between the center of the first transmitting area 210 and the center of the second receiving area 240 is between 4.5 mm and 9 mm;

[0067] And / or, the minimum distance between the center of the second transmitting area 220 and the center of the first receiving area 230 is between 5mm and 11mm.

[0068] The minimum distance between the center of the first transmitting area 210 and the center of the first receiving area 230 is defined as the first distance, and the minimum distance between the center of the first transmitting area 210 and the center of the second receiving area 240 is defined as the second distance, and the absolute difference between the first distance and the second distance is less than or equal to 3mm.

[0069] Furthermore, the second receiving area 240, the second transmitting area 220 and the first receiving area 230 are arranged sequentially upward along the height direction, the first transmitting area 210 is located to the side of the second transmitting area 220, and the height of the first transmitting area 210 is lower than the height of the first receiving area 230 and higher than the height of the second receiving area 240.

[0070] Please refer to Figure 4 Each of the first transmitting area 210 and the second transmitting area 220 is equipped with two IR lamps 260 and one RED lamp 250. The two IR lamps 260 are located on either side of the RED lamp 250. The RED lamp 250 and the IR lamps 260 serve as transmitting lamps to emit light beams. Each of the first receiving area 230 and the second receiving area 240 is equipped with a PD lamp 270 to receive the light beams emitted by the transmitting lamps. The distance ranges between each transmitting area and each receiving area are obtained through simulation experiments and calculations. Setting these distances within this range makes it easier for the monitoring element 200 to collect heart rate and blood oxygen data.

[0071] Furthermore, the headphones also include a housing containing a battery and a Bluetooth communication module. The battery powers the sound-generating element 300, the monitoring element 200, and the Bluetooth communication module. The Bluetooth communication module enables communication between the headphones and mobile devices, allowing them to function as wireless Bluetooth headphones. This allows them to be used in various fitness activities such as running, swimming, and cycling, playing sound and monitoring data such as heart rate and blood oxygen during exercise. In other words, it is an ear-hook wireless Bluetooth headphone with blood oxygen and heart rate monitoring functions.

[0072] Example 2

[0073] Please refer to Figures 1-2This embodiment discloses an earphone, including:

[0074] The earphone 100 includes an ear hook 130 and a first connecting part 110 and a second connecting part 120 respectively connected to both ends of the ear hook 130. The first connecting part 110 is provided with a sound-generating element 300 for generating sound; the second connecting part 120 is provided with a monitoring element 200 for monitoring heart rate and blood oxygen.

[0075] The line connecting the center of the sound-generating element 300 to the center of the monitoring element 200 is defined as the second connecting line 310. When the length direction of the first connecting part 110 is perpendicular to the horizontal plane, the angle between the second connecting line 310 and the horizontal plane is between 0° and 30°.

[0076] In this embodiment, using the sound-emitting element 300 as a reference, the angle between the second connecting line 310 and the horizontal plane is set between 0° and 30°. The position of the monitoring element 200 is determined by the position of the sound-emitting element 300. (To ensure that the shape of the earcup 100 can adapt to the shape of the auricle, the approximate positions of the first connecting part 110, the ear hook part 130, and the second connecting part 120 are basically fixed. Therefore, only the position of the monitoring element 200 in the second connecting part 120 needs to be determined to locate the position of the monitoring element 200 within the entire earphone.) This ensures that when the sound-emitting element 300 is aligned with the ear canal, the monitoring element 200 can be as close as possible to or against the back of the ear, so that at least a portion of the back of the ear is within the effective monitoring range covered by the monitoring element 200. Ultimately, while ensuring accurate monitoring of blood oxygen and heart rate, this earphone can be worn on more ears of different shapes and sizes, making it suitable for a wider range of people.

[0077] It should be noted that when wearing the headphones, you need to rotate them at a certain angle to achieve the most stable and comfortable fit. During this rotation, the second cable 310 will also rotate, and its angle with the horizontal plane will change accordingly.

[0078] Therefore, if a horizontal plane is used as a reference, the static state of the headphones needs to be selected to describe the second connection 310. In this embodiment, as... Figure 1 As shown, in this static state, the length direction of the first connecting part 110 is perpendicular to the horizontal plane, and the angle between the second connecting line 310 and the horizontal plane is between 0° and 30°.

[0079] Further, please refer to Figure 3 The monitoring element 200 has a first transmitting area 210, a second transmitting area 220, a first receiving area 230 and a second receiving area 240, and both the first receiving area 230 and the second receiving area 240 can receive light beams from the first transmitting area 210 and the second transmitting area 220.

[0080] The minimum distance between the center of the first launch area 210 and the center of the first receiving area 230 is between 4.5mm and 9mm;

[0081] And / or, the minimum distance between the center of the first transmitting area 210 and the center of the second receiving area 240 is between 4.5 mm and 9 mm;

[0082] And / or, the minimum distance between the center of the second transmitting area 220 and the center of the first receiving area 230 is between 5mm and 11mm.

[0083] The minimum distance between the center of the first transmitting area 210 and the center of the first receiving area 230 is defined as the first distance, and the minimum distance between the center of the first transmitting area 210 and the center of the second receiving area 240 is defined as the second distance, and the absolute difference between the first distance and the second distance is less than or equal to 3mm.

[0084] Furthermore, the second receiving area 240, the second transmitting area 220 and the first receiving area 230 are arranged sequentially upward along the height direction, the first transmitting area 210 is located to the side of the second transmitting area 220, and the height of the first transmitting area 210 is lower than the height of the first receiving area 230 and higher than the height of the second receiving area 240.

[0085] Please refer to Figure 4 Each of the first transmitting area 210 and the second transmitting area 220 is equipped with two IR lamps 260 and one RED lamp 250. The two IR lamps 260 are located on either side of the RED lamp 250. The RED lamp 250 and the IR lamps 260 serve as transmitting lamps to emit light beams. Each of the first receiving area 230 and the second receiving area 240 is equipped with a PD lamp 270 to receive the light beams emitted by the transmitting lamps. The distance ranges between each transmitting area and each receiving area are obtained through simulation experiments and calculations. Setting these distances within this range makes it easier for the monitoring element 200 to collect heart rate and blood oxygen data.

[0086] Furthermore, the minimum distance between the center of the sound-emitting element 300 and the center of the first emission area 210 is between 12mm and 18mm.

[0087] Specifically, after the headphones are put on, the center of the sound-emitting element 300 is aligned with the ear canal, and the back of the wearer's ear is positioned between the sound-emitting element 300 and the monitoring element 200. That is, as long as the minimum distance between the center of the wearer's ear canal and the back of the ear is between 12mm and 18mm, it ensures a stable fit while at least a portion of the back of the ear is covered by the effective monitoring range of the monitoring element 200, thus achieving smooth and accurate data acquisition. Therefore, this headphone can accommodate ear sizes of greater variation, making it suitable for a wider range of users.

[0088] Example 3

[0089] Please refer to Figures 1-2 This embodiment discloses an earphone, which is suspended from the auricle. The earphone includes:

[0090] The ear frame includes an ear hook and a first connecting part and a second connecting part respectively connected to both ends of the ear hook. A sound-generating element for emitting sound is provided in the first connecting part; and a monitoring element for monitoring heart rate and / or blood oxygen is provided in the second connecting part.

[0091] The ear-hanging part has a support section, and any point on the support section can serve as the highest support point and abut against the highest point of the suspension part.

[0092] The line connecting any highest support point to the center of the monitoring element is defined as the third line, and the projected length of the third line on the horizontal plane is between 20.4 mm and 28.3 mm.

[0093] Specifically, when a user wears the headphones, the suspension part at the upper end of the auricle abuts against the highest support point. At this time, the detection element is located on the back of the auricle and monitors the wearer's blood oxygen and heart rate. Setting the horizontal projection length of the first connecting line between 20.4mm and 28.3mm ensures that when any support point on the support section abuts against the suspension part, the detection element can be as close as possible to or against the back of the auricle, accommodating auricles of greater size and suitable for different users.

[0094] It is understandable that the first line 134 and the second line 310 described and defined in this case do not actually exist in the product, but are merely hypothetical line segments for the purpose of description and reference.

[0095] It should also be noted that during actual wear, the ear and earcup 100 do not make point-to-point contact, but rather surface-to-surface contact. The descriptions of the highest support point, etc., in this case are merely for ease of understanding and description, and do not imply a point-to-point contact between the earphone and the ear. The highest support point can also be understood as the center point or edge point of the highest contact surface between the earphone and earcup 100.

[0096] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
