Description
一种移动终端 Mobile terminal
技术领域 Technical field
本发明涉及一种移动终端,特别是涉及一种既可以保证铃音响度足够大, 又可以防止由于非常规操作铃音响度过大伤害人耳的移动终端。 The present invention relates to a mobile terminal, and more particularly to a mobile terminal capable of ensuring that the sound of the bell is sufficiently large, and that the human ear is prevented from being excessively damaged due to an unconventional operation.
背景技术 Background technique
随着移动终端在人们生活中的使用日益普遍, 其应用环境也是越来越复 杂。 移动终端不可避免地会在非常嘈杂的环境下使用, 比如施工工地、 地铁、 公交车, 闹市区和公共大型食堂等。 由于周围环境噪声比较大, 必然会影响 到人耳的听觉。 如果铃音响度不够大, 用户就很难在嘈杂环境下感知来电铃 音。 这样就可能导致漏接比较重要的来电, 影响到用户的正常工作。 因此, 移动终端厂家一般都会提高铃音响度来迎合市场需求, 因此市面上移动终端 的来电铃音的响度也是越来越大, 甚至有的移动终端铃音响度等级已经达到 了可能伤害人耳的地步, 如果在移动终端喇叭的出音孔靠近人耳时来电, 因 为铃音响度过大, 非常容易造成对人耳的伤害, 尤其是使用二合一喇叭的移 动终端。 As mobile terminals become more and more popular in people's lives, their application environment is becoming more and more complex. Mobile terminals are inevitably used in very noisy environments, such as construction sites, subways, buses, downtown areas, and public canteens. Due to the relatively large ambient noise, it will inevitably affect the hearing of the human ear. If the sound level of the bell is not large enough, it is difficult for the user to perceive the incoming call ring tone in a noisy environment. This may result in missed calls that are more important, affecting the normal work of the user. Therefore, mobile terminal manufacturers generally improve the bell sound level to meet the market demand, so the loudness of the ring tone of the mobile terminal on the market is also getting larger and larger, and even some mobile terminal bell sound level has reached the risk of hurting the human ear. At the same time, if the sound hole of the mobile terminal speaker is close to the human ear, because the bell sound is too loud, it is very easy to cause damage to the human ear, especially the mobile terminal using the two-in-one speaker.
为解决嘈杂环境下铃音响度不足与防止铃音响度过大伤害人耳的矛盾, 各个移动终端厂家也釆取了一些规避措施, 主要的规避措施有以下两种: 一 种是, 提供振动功能, 这个在一定程度上可以减少用户对铃音响度大小的依 赖, 但却受到移动终端携带方式的限制, 因为当移动终端在用户的随身口袋 里时, 因为移动终端距人体比较近, 来电时有振动, 用户就很容易感知到, 一般不会漏接来电; 而当移动终端在用户随身携带的包里时, 因为移动终端 距人体比较远, 来电时即使有振动, 用户也不容易感知到, 就很有可能漏接 来电。 另一种规避措施是, 移动终端釆用来电铃音渐变的模式, 即来电时铃 音的响度是从小到大逐渐的达到最大, 这种措施也在一定程度上緩解了铃音 响度和安全的矛盾。 在满足运营商对铃音响度限制的音频客观指标要求的同 时, 铃音响度有一定程度的提升, 但是其铃音响度还是无法满足用户在嘈杂 环境下使用的需求。
发明内容 In order to solve the contradiction between the lack of sound quality in the noisy environment and the prevention of excessive sounding of the bell, the mobile terminal manufacturers have also taken some evasive measures. The main evasive measures are as follows: One is to provide vibration function. This can reduce the user's dependence on the size of the bell to a certain extent, but it is limited by the way the mobile terminal is carried, because when the mobile terminal is in the user's pocket, because the mobile terminal is closer to the human body, there are Vibration, the user can easily perceive, generally do not miss the call; and when the mobile terminal is in the bag that the user carries, because the mobile terminal is far away from the human body, even if there is vibration when the call is made, the user is not easy to perceive, It is very likely that the call will be missed. Another circumvention measure is that the mobile terminal is used to mode the electric ring tone, that is, the loudness of the ring tone is gradually increased from small to large, and this measure also relieves the sound and safety of the bell to some extent. contradiction. While satisfying the operator's requirements for the audio objective indicators of the bell's sound limit, the bell sound level has been improved to a certain extent, but the bell sound level still cannot meet the user's needs in noisy environments.

为使本发明的目的、 技术方案和优点更加清楚明白, 下文中将结合附图 对本发明的实施例进行详细说明。 需要说明的是, 在不冲突的情况下, 本申 请中的实施例及实施例中的特征可以相互任意组合。 In order to make the objects, the technical solutions and the advantages of the present invention more clearly, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be arbitrarily combined with each other.
在本实施例的移动终端的正面壳体内侧, 在出音孔的位置处设置有阻尼 装置, 例如设置厚阻尼布等, 还可以减小正面出音孔的面积和个数, 进而降 低正面出音的响度。 本发明的移动终端在除正面外的任一面上, 设置有至少一个出音孔。 特 别是在喇叭前音腔的侧面上增加侧出音孔, 出音孔的位置可以在左右两侧面, 也可以在上下两侧面上, 当然也可以在背面上。 侧出音孔的个数可以是一个, 也可以是多个。 In the inner side of the front casing of the mobile terminal of the embodiment, a damping device is disposed at a position of the sound hole, for example, a thick damper cloth is provided, and the area and the number of the front sound hole can be reduced, thereby reducing the front surface. The loudness of the sound. The mobile terminal of the present invention is provided with at least one sound hole on either side except the front side. In particular, the side sound hole is added to the side of the front sound chamber of the speaker, and the sound hole can be located on the left and right sides, on the upper and lower sides, or on the back side. The number of side sound holes may be one or more.
本发明实施例只列举最常规的一种多出音孔设计, 如图 1 所示, 1是移 动终端正面的出音孔, 2是在本实施例移动终端左侧面上设置的出音孔, 3是 在本实施例移动终端右侧面上设置的出音孔, 4是在本实施例移动终端上侧 面上设置的出音孔, 用来增加有效出音面积, 分流正面出音孔的能量。 The embodiment of the present invention only cites the most conventional multi-sound hole design. As shown in FIG. 1 , 1 is a sound hole on the front side of the mobile terminal, and 2 is a sound hole disposed on the left side of the mobile terminal of the embodiment. 3 is a sound hole provided on the right side of the mobile terminal of the embodiment, and 4 is a sound hole provided on the upper side of the mobile terminal of the embodiment, for increasing the effective sound output area and diverting the front sound hole. energy.
图 2是本发明实施例的移动终端的喇八音腔的侧视剖面图, 图 3 是本发 明实施例的移动终端的喇叭音腔的正视剖面图, 如图 2所示, 在本实施例的 移动终端的正面壳体内侧, 出音孔 1的位置处设置有阻尼装置 22, 例如较厚 的阻尼布。 喇叭单体 20的后音腔 24为密闭型, 这样可以避免前音腔与后音 腔声波相互干涉, 影响铃音响度。 在喇叭出音孔设计时, 除了常规的在移动 终端喇叭的正面出音孔 1外, 同时在移动终端的两个侧面各增加了一个出音 孔, 如图 3的左侧出音孔 2和右侧出音孔 3 , 或在终端的上侧面增加一个上 侧出音孔 4。 这样本实施例的移动终端可以减少来电铃音从正面出音孔输出 的分量, 由此带来的铃音响度的损失则通过两个侧出音孔(或上侧出音孔) 来补偿。 2 is a side cross-sectional view of a horn cavity of a mobile terminal according to an embodiment of the present invention, and FIG. 3 is a front cross-sectional view of a horn cavity of a mobile terminal according to an embodiment of the present invention, as shown in FIG. The inside of the front casing of the mobile terminal is provided with a damping device 22, such as a thicker damping cloth, at the position of the sound hole 1. The rear sound chamber 24 of the horn unit 20 is sealed, so that the sound waves of the front sound chamber and the rear sound chamber can be prevented from interfering with each other, which affects the sound quality of the bell. In the design of the speaker sound hole, in addition to the conventional sound hole 1 on the front side of the mobile terminal speaker, a sound hole is added to each side of the mobile terminal, as shown in the left sound hole 2 of FIG. The sound hole 3 on the right side, or an upper sound hole 4 is added to the upper side of the terminal. Thus, the mobile terminal of the present embodiment can reduce the component of the ringing tone output from the front sound hole, and the loss of the bell sound is compensated by the two side sound holes (or the upper sound hole).
对于复合膜的喇叭后音腔需要做密闭处理, 而常规振膜的喇叭则不是强 制要求的, 但做密闭处理的话, 音响效果更好。 一般要求后音腔的密闭音腔 至少 1CC (立方厘米)以上,如果要取得理想的效果,要求后音腔要达到 1.5CC 以上。
本实施例中侧出音孔的导音管道与喇八的前音腔 23相连通,并且避免过 于狭长和过多弯折。 For the horn of the composite membrane, the sound cavity needs to be sealed, and the horn of the conventional diaphragm is not mandatory, but if it is sealed, the sound effect is better. Generally, the closed sound chamber of the rear sound chamber is required to be at least 1 cc (cubic centimeters) or more. If the desired effect is to be achieved, the rear sound chamber is required to reach 1.5 cc or more. In the present embodiment, the sound guiding duct of the side sound hole communicates with the front sound chamber 23 of the Rab, and avoids excessively long and excessive bending.
本实施例的移动终端其工作原理是, 声音的响度随着距离的增加是成平 方衰减的, 因此移动终端到人耳的距离只要不小于 10cm, —般不会因为铃音 过大而伤害到人耳, 而对于限制铃音响度的客观音频指标, 则是防止在极端 情况下, 即喇叭出音孔贴近人耳时突然来电, 如果铃音响度过大就会很容易 伤害的人耳。 而本发明则正是为了避免这种情况, 在贴近人耳的出音孔加厚 了阻尼布的厚度, 即增加了声阻尼, 进而减少了喇叭正面出音孔输出的能量, 降低铃音的响度, 保证在极端情况下不至于伤害人耳。 这个措施势必会影响 来电铃音的响度, 但可以通过增加侧面出音孔来弥补正面出音的损失。 The working principle of the mobile terminal of this embodiment is that the loudness of the sound is squared with the increase of the distance, so the distance from the mobile terminal to the human ear is not less than 10 cm, and generally does not hurt because the ring tone is too large. The human ear, and the objective audio index that limits the sound level of the bell, is to prevent sudden calls when the speaker sound hole is close to the human ear in extreme cases. If the bell sound is too loud, it will easily hurt the human ear. The present invention is precisely to avoid this situation, the thickness of the damper cloth is thickened in the sound hole close to the human ear, that is, the sound damping is increased, thereby reducing the energy output from the sound hole of the front surface of the horn, and reducing the ring tone. Loudness, to ensure that in the extreme case does not hurt the human ear. This measure will inevitably affect the loudness of the incoming ring tone, but it can compensate for the loss of the frontal sound by adding a side sound hole.
本发明的技术特点在于, 根据人们打电话的习惯, 一般人耳都会正对移 动终端喇叭的正面出音孔, 那么降低正面出音的响度, 就可以减少直达声对 人耳的伤害; 而通过增加侧出音孔既可以降低正面出音的响度, 保护人耳, 又可以弥补正面出音响度的不足的问题, 从而达到一举两得的效果。 The technical feature of the present invention is that, according to the habit of people calling, the general human ear will face the front sound hole of the mobile terminal horn, then reducing the loudness of the frontal sound can reduce the damage of the direct sound to the human ear; The side sound hole can not only reduce the loudness of the frontal sound, but also protect the human ear, and can also make up for the problem of lack of sound on the front side, thereby achieving the effect of two birds.
釆用本发明的移动终端不但可以满足运营商提出的限制来电铃音响度的 客观音频指标的要求, 而且可以有效的緩解铃音音量不够大的问题, 尤其是 对于提供给对来电铃音响度有客观指标要求的运营商的移动终端, 本发明提 供了一种有效的解决方法。 The mobile terminal of the present invention can not only meet the requirements of the objective audio index proposed by the operator to limit the sound quality of the incoming call bell, but also effectively alleviate the problem that the ring tone volume is not large enough, especially for providing the sound quality of the incoming call bell. The present invention provides an effective solution for the mobile terminal of the operator required by the objective index.
以上仅为本发明的优选实施例, 当然, 本发明还可有其他多种实施例, 在不背离本发明精神及其实质的情况下, 熟悉本领域的技术人员当可根据本 发明作出各种相应的改变和变形, 但这些相应的改变和变形都应属于本发明 所附的权利要求的保护范围。 The above is only a preferred embodiment of the present invention, and of course, the present invention may be embodied in various other embodiments without departing from the spirit and scope of the invention. Corresponding changes and modifications are intended to be included within the scope of the appended claims.
