Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, a person of ordinary skill in the art would be able to obtain all other embodiments based on the present application, which fall within the scope of the present utility model.

As described in the background art, in the related art, along with the development of the light and thin terminal, the speaker space is smaller and smaller, and is affected by the product space, the material and other aspects, the loudness of the speaker of the handheld terminal is not high, and the audio and video experience is poor in noisy environments.

In view of this, as shown in fig. 1 and 2, the embodiment of the first aspect of the present application proposes a terminal fitting 10 applied to a terminal body 20, at least one speaker 200 being provided inside the terminal body 20, the speaker 200 including a magnet 210, the terminal fitting 10 including a fitting body 100 and at least one first magnetic member 130 installed in the fitting body 100; the fitting body 100 is detachably mounted outside the terminal body 20, and the position of the first magnetic member 130 corresponds to the position of the speaker 200 of the terminal body 20.

In the present embodiment, the terminal fitting 10 includes a fitting body 100 and a first magnetic member 130 mounted in the fitting body 100, the first magnetic member 130 corresponding in position to the speaker 200 after the fitting body 100 is mounted to the outside of the terminal body 20. When the first magnetic member 130 is attracted to the magnet 210 of the speaker 200, the magnetic circuit around the speaker 200 can be reinforced, so that the driving force value of the speaker 200 can be increased, and the mid-frequency sensitivity of the speaker 200 can be improved. By increasing the mid-frequency sensitivity, the loudness of the speaker 200 can be increased, thereby facilitating an improved audio-visual experience in noisy environments.

Specifically, in the first embodiment of the present application, as shown in fig. 1 and 2, the terminal fitting 10 is a protective case, and the fitting body 100 includes an upper cover 110 and a lower cover 120 of the protective case. The speaker 200 is provided with a plurality of first magnetic members 130, a part of the first magnetic members 130 are located on the upper cover 110, and a part of the first magnetic members 130 are located on the lower cover 120. When the accessory body 100 is mounted on the outside of the terminal body 20, the first magnetic member 130 of the lower cover 120 may attract the magnet 210, so that the driving force value of the speaker 200 is increased and the loudness is increased. After the protective cover is closed, the first magnetic member 130 located on the upper cover 110 may also attract the magnet 210, so as to increase the driving force value of the speaker 200 and increase the loudness.

Further, as shown in fig. 3 and 4, one first magnetic member 130 located at the upper cover 110 corresponds to one first magnetic member 130 located at the lower cover 120 at the same speaker 200 position of the terminal body 20, respectively. Thus, after the protective covers are closed, each speaker 200 may attract two first magnetic members 130, one of which is located on a side of the display panel 300 facing away from the speaker 200, and the other is located on a side of the rear cover 400 facing away from the speaker 200.

According to the experimental verification of the inventor, the loudness value may be raised by about 3db when the speaker 200 is attracted to one first magnetic member 130, and by about 6db when the speaker 200 is simultaneously attracted to two first magnetic members 130.

Therefore, in this embodiment, after the protective sleeve is folded, the magnetic circuit around the speaker 200 may be further reinforced, so that the driving force value of the speaker 200 is further improved, and further, the mid-frequency sensitivity of the speaker 200 is further improved, and the loudness of the speaker 200 is further increased.

In a specific embodiment, as shown in fig. 1 to 4, the terminal body 20 is provided with four speakers 200 in different areas, and accordingly, the first magnetic members 130 are provided with eight, wherein four first magnetic members 130 are located on the upper cover 110, and the other four first magnetic members 130 are located on the lower cover 120, and one first magnetic member 130 located on the upper cover 110 and one first magnetic member 130 located on the lower cover 120 correspond to the same speaker 200 of the terminal body 20. Thus, each speaker 200 may correspond to two first magnetic members 130, which is advantageous for further improving the driving force value of the speaker 200, further improving the mid-frequency sensitivity of the speaker 200, and further increasing the loudness of the speaker 200.

In other embodiments of the present application, the terminal body 20 is provided with a plurality of speakers 200 in different areas, and the first magnetic member 130 located on the upper cover 110 corresponds to a portion of the speakers 200, and the first magnetic member 130 located on the lower cover 120 corresponds to another portion of the speakers 200, that is, each speaker 200 corresponds to only one of the first magnetic members 130. Alternatively, a part of the speakers 200 corresponds to one first magnetic member 130 located at the upper cover 110 and one first magnetic member 130 located at the lower cover 120 at the same time, and another part of the speakers 200 corresponds to only one first magnetic member 130 located at the upper cover 110 or one first magnetic member 130 located at the lower cover 120. The present application is not limited in this regard.

In other embodiments of the present application, the terminal body 20 is provided with only one speaker 200, and the first magnetic member 130 is located at the upper cover 110 and the lower cover 120 and corresponds to the positions of the speakers 200, respectively. Therefore, when the protective sleeve is folded, the magnet 210 of the speaker 200 can attract the two first magnetic members 130, so that the driving force value of the speaker 200 is further improved, the mid-frequency sensitivity of the speaker 200 is further improved, and the loudness of the speaker 200 is further increased.

Fig. 5 shows a split structure diagram of a speaker 200 according to a first embodiment of the present application, as shown in fig. 5, the speaker 200 includes a dome 220, a diaphragm 240, a voice coil 230, a bracket 250, an annular pole piece 260, a pole piece 261, and a yoke 270, where the voice coil 230 is connected to the dome 220, and the voice coil 230 is configured to vibrate after being energized, so as to drive the dome 220 to vibrate, thereby implementing electroacoustic signal conversion. The diaphragm 240 surrounds the dome 220, two ends of the bracket 250 are respectively connected with the diaphragm 240 and the magnet 210, the annular pole piece 260 and the pole piece 261 are arranged on the same layer and are positioned on one side of the magnet 210, which is close to the dome 220, and the annular pole piece 260 and the pole piece 261 are used for magnetic conduction, so that magnetic induction lines are distributed more uniformly. The yoke 270 is located on the side of the magnet 210 facing away from the dome 220, and the yoke 270 is used for magnetic conduction, so that magnetic induction lines are distributed more uniformly. In the speaker 200, the magnet 210 may also be referred to as magnetic steel.

As shown in fig. 6 and 7, the inside of the terminal body 20 is provided with a Box cavity 600, the speaker 200 is located in the Box cavity 600, the terminal body 20 includes a display panel 300 and a rear cover 400, and the Box cavity 600 is located between the display panel 300 and the rear cover 400.

It should be noted that, as shown in fig. 6, in the embodiment of the present application, the sound outlet channel 410 of the speaker 200 is located at a side of the rear cover 400. Therefore, even if the two first magnetic members 130 are respectively positioned at the side of the display panel 300 facing away from the speaker 200 and the side of the rear cover 400 facing away from the speaker 200 after the terminal fitting 10 is mounted outside the terminal body 20, the sound output of the speaker 200 is not affected.

As shown in fig. 7, the lower cover 120 of the accessory body has a certain distance between the first magnetic member 130 of the lower cover 120 and the yoke 270 of the speaker 200 after being mounted outside the rear cover 400. This distance setting has a certain effect on the degree of loudness increase of the loudspeaker 200. As shown in fig. 7, the first magnetic member 130 located at the lower cover 120 may have a distance of 0.5-1.5mm from the yoke 270 after the terminal fitting 10 is mounted at the outside of the terminal body 20. Thus, the driving force value of the speaker 200 can be effectively improved. Specific:

the loudness of the loudspeaker 200 is mainly related to the mid-frequency sensitivity.

The intermediate frequency sensitivity is calculated as follows:

from the formula, the intermediate frequency sensitivity is mainly related to the driving force Bl and the mass M of the vibration system _MS Area of vibration S _D Voice coil 230 DC resistor R _E And the like. The intermediate frequency sensitivity is proportional to the driving force Bl, and the larger the driving force Bl, the larger the intermediate frequency sensitivity and the larger the loudness. The driving force Bl is mainly determined by the magnetic force of the magnet 210, and is also influenced by material and volume factors.

Through experiments and verification of the inventor, the driving force Bl value can be effectively improved by making the first magnetic member 130 correspond to the position of the loudspeaker 200 and magnetically attract the magnet 210.

Specifically, fig. 8 shows a magnetic induction diagram of the speaker 200 when the first magnetic member 130 is not provided, fig. 9 shows that the first magnetic member 130 is located at one side of the speaker 200, fig. 10 shows a magnetic induction diagram of the speaker 200 when the first magnetic member 130 is 1mm from the yoke 270 in fig. 9, and fig. 11 shows a magnetic induction diagram of the speaker 200 when the first magnetic member 130 is 1.5mm from the yoke 270 in fig. 9. As can be seen from comparing fig. 8 and 10 with fig. 8 and 11, after the first magnetic member 130 is disposed, the magnetic path around the speaker 200 is enhanced, and the magnetic flux is increased. For reference, the size model of the speaker 200 is 16×20×2.3 (unit: mm).

Fig. 12 shows a Bl curve a measured when the first magnetic member 130 is not provided, a Bl curve b measured when the first magnetic member 130 is 1mm apart from the yoke 270, and a Bl curve c measured when the first magnetic member 130 is 1.5mm apart from the yoke 270. It can be intuitively seen that, with respect to the curve a, the curves b and c are lifted, that is, by providing the first magnetic member 130, the driving force Bl is lifted as a whole.

According to the simulation data calculation, the loudness value is 94.8dB without the first magnetic member 130, the loudness value is 96.6dB when the distance between the first magnetic member 130 and the yoke 270 is 1mm, the loudness value is 96.9dB when the distance between the first magnetic member 130 and the yoke 270 is 1.5mm, and the loudness value is improved by about 3dB, which means that the sound level is doubled and the loudness improvement is obvious.

Therefore, in the embodiment of the present application, by arranging the first magnetic member 130 on the terminal fitting 10, and making the first magnetic member 130 correspond to the position of the speaker 200 and magnetically attract the magnet 210, the loudness of the speaker 200 can be increased, thereby being beneficial to improving the audio-visual experience in a noisy environment.

In fig. 12, the negative half axis of the abscissa indicates that the voice coil 230 vibrates in a direction toward the magnet 210, and the positive half axis indicates that the voice coil 230 vibrates in a direction away from the magnet 210. The amount of lift of the Bl curve on the negative half axis is slightly larger than that on the positive half axis because the portion of the voice coil 230 that is enclosed in the magnet 210 is larger when vibrating in the direction toward the magnet 210.

As shown in fig. 10 to 12, according to the simulation analysis of the inventor, when the distance between the first magnetic member 130 and the yoke 270 of the speaker 200 is 1mm or 1.5mm, the magnetic circuit of the speaker 200 is significantly reinforced and the driving force value is significantly increased. Therefore, by making the distance between the first magnetic member 130 and the yoke 270 be 0.5-1.5mm after the terminal fitting 10 is mounted on the outside of the terminal body 20, the driving force value of the speaker 200 can be effectively improved, thereby being beneficial to improving the mid-frequency sensitivity of the speaker 200 and further beneficial to improving the loudness of the speaker 200.

In a specific embodiment, as shown in fig. 7, the magnet 210 of the speaker 200 is located toward the rear cover 400, that is, the yoke 270 is located at a side of the speaker 200 near the rear cover 400, and the speaker 200 may be fixed to the rear cover 400 by screws. The rear cover 400 has a thickness of about 0.5mm, and a distance between the first magnetic member 130 of the lower cover 120 and the magnet 210 of the speaker 200 is about 0.65mm. In addition, by adjusting the position of the first magnetic member 130 in the protection cover, the distance between the first magnetic member 130 and the magnet 210 of the speaker 200 can reach 1mm or other specific values, so that the loudness value is high.

In the first embodiment of the present application, the first magnetic member 130 is a block magnet. Thus, the first magnetic member 130 has a simple structure and low cost.

In other embodiments of the present application, the first magnetic member 130 may also be a sheet-shaped magnet, a bar-shaped magnet, or a magnet of other shapes, which is not limited in this application.

As shown in fig. 7, in the first embodiment of the present application, after the accessory body 100 is mounted on the outside of the terminal body 20, the projection size of the first magnetic member 130 on the rear cover 400 is smaller than the projection size of the magnet 210 of the speaker 200 on the rear cover 400. Thereby, the production cost of the terminal fitting 10 can be reduced.

In other embodiments of the present application, the first magnetic member 130 may be located only on the upper cover 110 or only on the lower cover 120, which is not limited in this application.

As shown in fig. 1 to 4, in the first embodiment of the present application, the fitting body 100 further includes a connection portion 150, and the connection portion 150 is used to connect the upper cover 110 and the lower cover 120.

In the first embodiment of the present application, the terminal body 20 is further provided with a hall switch; the terminal fitting 10 further includes a second magnetic member 140, and the second magnetic member 140 is located at a position of the fitting body 100 corresponding to the hall switch.

The Hall switch is a magneto-electric conversion device, which is manufactured by utilizing an integrated packaging and assembling process on the basis of the Hall effect principle, the input end of the Hall switch is characterized by magnetic induction intensity, and when the magnetic induction intensity reaches a certain value, a trigger inside the Hall switch is turned over, and the output level state of the Hall switch is turned over.

In this embodiment, the second magnetic member 140 may induce the hall switch while the first magnetic member 130 attracts the magnet 210 of the speaker 200, so that the output level of the hall switch is inverted. Therefore, the processor in the terminal body 20 can adjust the sound effect parameters after receiving the overturning signals of the hall switch, so that the sound effect parameters are matched with the improved loudness value, the effect of the loudspeaker 200 is optimal, and the sound effect requirements of different scenes of the terminal body 20 are met.

Specifically, in the first embodiment of the present application, as shown in fig. 1 and 2, the terminal body 20 is provided with a first hall switch 500 and a second hall switch 510 inside, and two second magnetic members 140 are provided, wherein one second magnetic member 140 is located on the upper cover 110, and the other second magnetic member 140 is located on the lower cover 120. The second magnetic member 140 located on the lower cover 120 corresponds to the first hall switch 500 in position, and the second magnetic member 140 located on the upper cover 110 corresponds to the second hall switch 510 in position.

In the case where the protective case is not installed, the processor inside the terminal body 20 invokes the first set of sound effect parameters, in the normal volume mode. Under the condition that the external installation protective sleeve of the terminal body 20 and the upper cover 110 of the protective sleeve are opened, the first magnetic part 130 positioned on the lower cover 120 is attracted to the magnet 210, the magnetic field of the loudspeaker 200 is enhanced, the driving force value is improved, meanwhile, the first Hall switch 500 senses the second magnetic part 140 positioned on the lower cover 120, the first Hall switch 500 is opened, the processor inside the terminal body 20 invokes the second set of sound effect parameters after recognizing that the first Hall switch 500 is opened, and the loudness is improved by about 3db. After the protection cover is folded, the first magnetic part 130 located on the upper cover 110 is also attracted to the magnet 210, the magnetic field of the loudspeaker 200 is further enhanced, the driving force value is further improved, meanwhile, the second hall switch 510 senses the second magnetic part 140 located on the upper cover 110, the second hall switch 510 is also opened, the processor inside the terminal body 20 invokes a third set of sound effect parameters after recognizing that both hall switches are opened, an oversized sound volume mode is started, and the loudness is improved by about 6dB.

It should be noted that, by providing the first magnetic member 130, the driving force value of the speaker 200 may be enhanced, so that the loudness of the speaker 200 may be increased, which means an increase in amplitude. Because the existing diaphragm technology already supports single-side 0.9mm large amplitude, the diaphragm technology can completely bear the increase of the amplitude. In addition, the amplitude is increased from 0.3mm to 0.4mm, and the amplitude is increased from 0.4mm to 0.5mm, so that the loudness is increased by more than 3dB, and the frequency is correspondingly increased, but the total harmonic distortion of the super-linear kernel is lower, and the frequency response is increased appropriately, but the debugging and the performance are not affected.

In the first embodiment of the present application, the second magnetic member 140 is also a block magnet. Thus, the second magnetic member 140 has a simple structure and low cost.

In other embodiments of the present application, the second magnetic member 140 may also be a sheet-shaped magnet, a bar-shaped magnet, or a magnet of other shapes, which is not limited in this application.

By increasing the mid-frequency sensitivity, the loudness of the speaker 200 can be increased, thereby facilitating an improved audio-visual experience in noisy environments.

It can be appreciated that, in the embodiment of the present application, since the first magnetic member 130 is located in the fitting body 100, the thickness of the terminal body 20 is not increased while the loudness is being raised.

In addition, in the embodiment of the application, since the first magnetic member 130 in the accessory body 100 can attract the magnet 210 of the speaker 200, the magnet 210 attracted to the first magnetic member 130 does not need to be additionally arranged inside the terminal body 20, and the magnet 210 of the speaker 200 can replace the whole magnet 210, so that the loudness can be improved and the terminal cost can be reduced. For example, when the accessory body 100 is a protective case, the first magnetic member 130 disposed on the protective case top cover 110 can attract the magnet 210 of the speaker 200 to close the protective case, so that there is no need to additionally dispose another magnet 210 attracted to the first magnetic member 130 in order to close the protective case inside the terminal body 20.
